10 Gigabit Ethernet is the single most transformative upgrade you can make to a NAS setup. But only if your workload actually demands it. A 1GbE connection supports approximately 110 MB/s of sustained SMB throughput when no other bottleneck is present. A 10GbE connection lifts that ceiling to approximately 1,100 MB/s. Nearly 10x the throughput. For demanding workloads, 10GbE can remove a 1GbE or 2.5GbE bottleneck, provided the NAS, storage, client and protocol can sustain the higher throughput. But the upgrade is not free, and it is not simple. This guide covers what Australian buyers need to know: the hardware, the cabling, the costs, and the mistakes to avoid.
In short: 10GbE is worth the investment for video editors, multi-user business file servers, and all-flash NAS setups where 2.5GbE still bottlenecks performance. 10GbE switch pricing varies widely with port count, connector type and management features; verify current Australian prices for the selected model. If your workload is single-user Plex streaming, photo backups, or general file storage, 2.5GbE is the smarter choice at a fraction of the cost.
When 10GbE Is Worth It (and When 2.5GbE Is Enough)
The decision between 10GbE and 2.5GbE is not about which is faster. Obviously 10GbE wins. The real question is whether your workload will actually benefit from the extra speed, and whether the cost is justified for your situation.
10GbE makes sense when:
- You edit video directly from a NAS and your specific codec, resolution, frame rate and stream count require sustained throughput above 300 MB/s.
- Multiple users access the NAS simultaneously. A 10GbE connection to the NAS can serve several 1GbE or 2.5GbE clients at full speed
- You run an all-flash or SSD-cached NAS where the drives can actually deliver 10GbE-class speeds
- You transfer large datasets regularly. VM images, RAW photo catalogues, database dumps. And waiting is costing you time
- You run iSCSI targets or virtualisation storage where latency and bandwidth both matter
2.5GbE is enough when:
- You are a single user streaming Plex media, backing up files, or running a home file server
- Your NAS uses spinning hard drives in RAID. Four-drive HDD RAID 5 performance varies substantially with the NAS, drives, RAID implementation and workload; compare tested results for the exact system with the usable throughput of 2.5GbE.
- You want a meaningful speed boost without re-cabling your house or paying for 10GbE switching
The Port Speed Isn't the Whole Story: CPU and RAM Matter Too
A 2.5GbE port only guarantees a faster link between the NAS and your switch, not that the NAS can actually sustain that speed for real work. Budget 2-bay units built around entry-tier CPUs, often paired with just 1-2GB of RAM, can struggle to hold 2.5GbE line-rate (roughly 280 MB/s real-world) once you move past a simple file copy. SMB encryption, antivirus scanning, or a background cloud-sync app like Synology C2 or QNAP HybridMount running at the same time all eat into that CPU/RAM headroom. This gap can be less visible on Gigabit because 1GbE itself carries only about 110 MB/s; many current NAS hard drives can exceed that in sequential transfers. It matters more at 2.5GbE and above, where the network stops being the limiting factor and the NAS's own processor and memory start to be. Before paying extra for a 2.5GbE model, check its CPU class and RAM against what you actually plan to run, not just the port speed on the spec sheet.
The multi-user multiplier: Even if each client only has a 1GbE or 2.5GbE connection, a 10GbE uplink on the NAS prevents congestion when multiple people access the NAS at the same time. A small office with four editors pulling footage simultaneously can saturate a 2.5GbE NAS link easily. A 10GbE NAS uplink gives headroom for everyone.
10GbE PCIe Card Options for NAS
Most NAS units do not include 10GbE ports out of the box. The standard upgrade path is a PCIe network adapter card that slots into your NAS (if it has a PCIe expansion slot) or into your desktop/workstation. There are two categories: RJ45 copper cards and SFP+ fibre/DAC cards. Each has trade-offs that matter for Australian buyers.
Synology 10GbE Adapter Cards
| Model | Synology E10G30-T1 |
|---|---|
| Type | Single-port 10GbE RJ45 (copper) |
| Interface | PCIe 3.0 x4 |
| Compatible NAS | DS1825+, DS1823xs+, DS1821+, DS1621+ and other models on Synology's list; the DS1525+ takes only the E10G22-T1-Mini |
| Cheapest AU listing | $282 (I-Tech) |
| Data transfer rates | 10 Gbps/5 Gbps/2.5 Gbps/1 Gbps/100 Mbps |
The E10G30-T1 is a single-port 10GbE 10GBASE-T add-in card for Synology systems; it replaces the E10G18-T1, which is end-of-life. It uses RJ45 copper, which means you can connect it with standard Ethernet cables (Cat6 minimum). Compatibility is model-specific, so check Synology's list for the exact NAS before purchasing.
| Model | Synology E10G30-F2 |
|---|---|
| Type | Dual-port 10GbE SFP+ |
| Interface | PCIe 3.0 x8 |
| Use Case | Link aggregation, failover, fibre connections |
| Cheapest AU listing | $465.83 (MegaBuy) |
The E10G30-F2 is the dual-port SFP+ card for Synology NAS units. SFP+ uses either fibre optic transceivers or direct-attach copper (DAC) cables rather than RJ45. The dual ports enable link aggregation or failover for business-critical deployments. It costs more than a single-port card such as the E10G30-T1. It only makes sense if you need SFP+ specifically (matching your switch infrastructure) or need two ports. For a new home or prosumer deployment, choose a current single-port adapter that appears in Synology's compatibility list for the exact NAS model.
QNAP 10GbE Adapter Cards
| Model | QNAP QXG-10G2T-X710 |
|---|---|
| Type | Dual-port 10GbE RJ45 (copper) |
| Interface | PCIe 3.0 x4 |
| Chipset | Intel X710 |
| Compatible NAS | model-specific. Confirm the exact NAS and adapter combination in QNAP's compatibility database before purchasing. |
| Cheapest AU listing | $649 (Scorptec) |
QNAP's QXG-10G2T-X710 is a dual-port 10GbE card built on the Intel X710 chipset, which supports SR-IOV for virtualisation workloads. It costs more than a single-port card such as the E10G30-T1, but it gives you two 10GbE ports. QNAP also offers single-port 10GbE and 5GbE cards, though availability varies at Australian retailers.
Compatibility matters: Both Synology and QNAP maintain compatibility lists for their PCIe cards. Not every NAS model has a PCIe slot, and not every slot supports every card. The DS225+ and DS425+ (Synology's newer 2-bay and 4-bay Plus models) do not have PCIe slots at all. They ship with 2.5GbE built in. Check your NAS model's specifications before purchasing a 10GbE card.
10GbE Switch Options for Australian Buyers
A 10GbE adapter in your NAS is only half the equation. You also need a switch (or a direct connection) that supports 10GbE. This is where costs escalate and where Australian buyers need to plan carefully. Consumer-grade 10GbE switches are still niche in Australia, and enterprise switches carry enterprise pricing.
There are two main approaches: QNAP QSW unmanaged switches (purpose-built for NAS networking) and Ubiquiti UniFi managed switches (for users already in the UniFi ecosystem or who want management features). A third option, a direct point-to-point connection between NAS and workstation, avoids the switch cost entirely.
Network Switch Options
| QNAP QSW-2104-2T-R2 | QNAP QSW-1105-5T | Ubiquiti Flex Mini 2.5G (USW-Flex-2.5G-5) | Ubiquiti Flex 2.5G (USW-Flex-2.5G-8) | Ubiquiti Pro XG 10 PoE (USW-Pro-XG-10-PoE) | |
|---|---|---|---|---|---|
| 10GbE Ports | 2x 10GBASE-T RJ45 | None (2.5GbE only) | None (2.5GbE only) | 1x 10 GbE RJ45/SFP+ combination uplink port | 10 × 10GbE RJ45 PoE+++ ports + 2 × 10G SFP+ ports. |
| 2.5GbE / 1GbE Ports | 4x 2.5GbE | 5x 2.5GbE | 5x 2.5GbE | 8x 2.5GbE | N/A |
| Managed | No | No | Yes (UniFi) | Yes (UniFi) | Yes (Layer 3) |
| Cheapest AU listing | $269 (Scorptec, Computer & Parts Land) | Check current listings | $95 (Landmark Computers, Computer & Parts Land, MSY, Umart) | $295 (Landmark Computers, Computer & Parts Land) | $1,199 (MSY, UMart) |
| Best For | NAS to workstation over Ethernet | Legacy 2.5GbE-only model | Compact 2.5GbE segment | Multi-device 2.5GbE segment | Business/prosumer full 10GbE |
The QNAP QSW-2104-2T-R2 is the current revision of this entry-level mixed 10GbE/2.5GbE switch; treat the original QSW-2104-2T as a legacy model. Its two 10GBASE-T RJ45 ports can connect a NAS and workstation using Ethernet cables, while four 2.5GbE RJ45 ports serve other devices. Choose the QSW-2104-2S if two SFP+ ports and DAC cables are required. At $269 (Scorptec), the QSW-2104-2T-R2 is a relatively affordable Australian option for two 10GBASE-T RJ45 ports plus four 2.5GbE ports. Stock availability varies by retailer and supplier, so check current availability before planning your build around it.
For a small all-10GbE network, the TP-Link TL-SX105 (our pick above) has five unmanaged 10GbE RJ45 ports and a market price of about $414. For full 10GbE switching across more ports, the Ubiquiti UniFi Pro XG 10-Port (USW-Pro-XG-10-PoE) is $1,199 at MSY and UMart and provides ten 10GbE RJ45 ports and two SFP+ ports with Layer 3 management. It is a serious investment, but for a small video production studio or a business file server serving multiple 10GbE workstations, it eliminates the bottleneck entirely. It also includes PoE+++ on its RJ45 ports, which may or may not be useful depending on your setup.
The Direct Connection Shortcut
If you only need 10GbE between one workstation and one NAS, skip the switch entirely. Connect your NAS 10GbE port directly to a 10GbE card in your PC with a single cable. This works with either RJ45 (Cat6/Cat6a cable) or SFP+ (DAC cable). Short SFP+ DAC cables are inexpensive. For a working point-to-point link, both adapters must use matching media: pair the E10G30-T1 with an RJ45 10GBASE-T PC card and Cat6/Cat6a cable, or use SFP+ adapters at both ends with a compatible DAC. No switch required.
Direct connection tip: When connecting NAS to PC directly without a switch, you need to assign static IP addresses on both 10GbE interfaces (e.g., 10.0.0.1 and 10.0.0.2 on a /24 subnet). Your regular 1GbE or Wi-Fi connection to your router handles internet traffic. The 10GbE link is purely for NAS-to-PC file transfers. Both Synology DSM and QNAP QTS support multiple network interfaces with different subnets natively.
Cabling: Cat6a vs SFP+ DAC vs Fibre
Cabling is where 10GbE upgrades can either stay affordable or spiral in cost. The choice depends on distance and what ports your equipment uses.
RJ45 Copper (Cat6 / Cat6a)
10GbE over RJ45 requires Cat6 cable for runs up to 55 metres and Cat6a for runs up to 100 metres. Cat5e is not specified to provide a guaranteed 10GBASE-T channel; existing short runs may work but should be tested. This is one of the key friction points: if your house is wired with Cat5e, you can upgrade to 2.5GbE without re-cabling, but 10GbE will require pulling new Cat6 or Cat6a cable through the walls. For short desktop runs (under 5 metres), a quality Cat6 patch cable is sufficient. For Cat6a structured cabling through walls or ceilings, use a registered cabler with the appropriate structured-cabling competency. Obtain a site-specific quote from a registered cabler, as cost depends on the run and installation conditions.
SFP+ Direct Attach Copper (DAC)
DAC cables are twinaxial copper cables with SFP+ connectors on each end. They are passive, inexpensive and low-latency, but suit short distances (typically 1-3 metres). DAC is the ideal solution when your NAS and workstation (or switch) are in the same rack or on the same desk. The downside: both ends need SFP+ ports, so your NAS card and switch must both have SFP+ rather than RJ45.
Fibre Optic (SFP+ with Transceivers)
For runs longer than a DAC cable can cover between SFP+ devices, fibre optic cables with SFP+ transceivers are the standard approach. A 10G multimode SFP+ transceiver such as Ubiquiti's UACC-OM-MM-10G-D is rated for 300 metres on OM3 and 400 metres on OM4 fibre, and single-mode (OS2) goes much further. The cables themselves are inexpensive, but each end needs an SFP+ transceiver module, which adds cost per port. This is primarily a business and rack environment solution. Most home users will never need fibre for NAS connectivity.
NAS Models with Built-In 10GbE
A handful of NAS models ship with 10GbE ports built in, eliminating the need for a separate PCIe card. These are primarily higher-end models aimed at business users, video editors, and all-flash deployments. Here are the key options available from Australian retailers.
QNAP Models with Built-In 10GbE
| Model | QNAP TS-h973AX-32G |
|---|---|
| Bays | 9 (5x 3.5" HDD + 4x 2.5" SSD) |
| CPU | AMD Ryzen V1500B (Quad-Core) |
| RAM | 32GB DDR4 |
| Built-In Network | 1x 10GbE RJ45 + 2x 2.5GbE RJ45 |
| Cheapest AU listing | $1,849 (Computer & Parts Land) |
| AU market price | about $2,174 |
The TS-h973AX is one of the most practical 10GbE NAS options for Australian prosumers and small businesses. It includes a 10GbE RJ45 port alongside two 2.5GbE ports, plus nine bays in a hybrid configuration that supports both HDDs and SSDs. The Ryzen V1500B CPU handles virtualisation and container workloads well. The TS-h973AX-32G has a market price of about $2,174, while the cheapest TS-h973AX-32G listing is $1,849 at Computer & Parts Land.
| Model | QNAP TVS-672XT-i3-8G |
|---|---|
| Bays | 6 (3.5" HDD) + 2x M.2 NVMe |
| CPU | Intel Core i3-8100T (Quad-Core) |
| RAM | 8GB DDR4 |
| Built-In Network | 1x 10GbE RJ45 + 2x 1GbE RJ45 + 2x Thunderbolt 3 |
| AU availability | Phased out by QNAP; some Australian retailers still list it |
| Successor | TVS-h674T (10GbE optional via PCIe card) |
The TVS-672XT is a legacy QNAP creative-workstation NAS with built-in 10GbE and Thunderbolt 3; QNAP has phased it out and names the TVS-h674T as its replacement, so it is not a current recommendation even though some Australian retailers still list it. Thunderbolt 3 provides a theoretical 40Gbps link and supports a direct SMB connection to a Mac or PC, but actual NAS file-transfer throughput depends on the storage, protocol and client configuration. Its successor, the TVS-h674T (market price about $5,041), has two Thunderbolt 4 ports and two 2.5GbE ports, with 10GbE optional via a PCIe expansion card, so it does not have built-in 10GbE. Unless you specifically need Thunderbolt, the TS-h973AX is the better fit for built-in 10GbE.
Asustor Models with Built-In 10GbE
Asustor's Flashstor Gen2 and Lockerstor Gen3 lines include models with built-in 10GbE. The Flashstor 6 Gen2 (FS6806X) has a market price of about $1,448, includes 10GbE and is designed as an all-flash 6-bay M.2 NAS. The Flashstor 12 Gen2 (FS6812X) has a market price of about $2,358 and adds dual 10GbE ports and 12 M.2 bays. These are niche products aimed at high-speed SSD storage rather than traditional HDD NAS setups.
Synology Models with 10GbE Options
Synology's 2025 Plus desktops (DS225+, DS425+, DS925+, DS1525+ and DS1825+) do not ship with built-in 10GbE; its xs+ models do. The DS1823xs+ has one 10GbE RJ45 port and the DS3622xs+ has two 10GbE ports; the DS1823xs+ has a market price of about $3,280. The Plus models with a slot take an add-in card instead: the DS1825+ supports the E10G30-T1, E10G30-T2 and E10G30-F2, and the DS1525+ takes the E10G22-T1-Mini in its network upgrade slot. For most Synology users, the path to 10GbE is a slot-equipped model such as the DS1825+ with the E10G30-T1 card.
Real-World 10GbE Throughput Expectations
Marketing materials say "10 Gbps." Reality is more nuanced. Here is what to actually expect from 10GbE NAS connections in typical Australian setups.
Illustrative 10GbE NAS Throughput
| 4-Bay HDD RAID 5 | 4-Bay HDD RAID 10 | SSD Cache + HDD | All-Flash (NVMe) | |
|---|---|---|---|---|
| Sequential Read | 400-500 MB/s | 350-450 MB/s | 500-800 MB/s (cached) | 900-1,100 MB/s |
| Sequential Write | 300-400 MB/s | 250-350 MB/s | 300-400 MB/s | 800-1,000 MB/s |
| 10GbE Saturated? | No. Drives are the bottleneck | No. Drives are the bottleneck | Partially. Depends on cache hit rate | Yes. Network becomes the bottleneck |
| 10GbE Benefit | Moderate (headroom for multi-user) | Moderate | Significant for hot data | Maximum benefit |
The critical takeaway: 10GbE does not make spinning hard drives faster. Four-bay RAID 5 throughput varies substantially with the NAS, drives, RAID implementation and workload; use tested results for the specific configuration. You will see a speed improvement over 2.5GbE, but not the full 10x increase the marketing implies. The real scenario where 10GbE is fully utilised is all-flash NAS deployments or when multiple users share the connection simultaneously.
The SMB multi-client overhead: SMB throughput varies with file size, copy tool, protocol features, client and server configuration, storage and CPU; do not assume a fixed overhead percentage. Small files (under 1 MB) are particularly affected. Don't expect 10GbE speeds when copying thousands of small files. Large sequential file transfers (video files, disk images) will get closest to theoretical maximums.
Common 10GbE Mistakes Australian Buyers Make
These are the common 10GbE mistakes that waste money or lead to disappointing results.
Mistake 1: Buying 10GbE with Cat5e Cabling
Cat5e does not reliably support 10GbE. A short Cat5e run may establish a 10GbE link, but reliable performance is not guaranteed by the cabling specification and should be tested. This is fine for 2.5GbE, but 10GbE requires Cat6 (up to 55m) or Cat6a (up to 100m). Before buying a 10GbE card, check what cabling you have. If it is Cat5e and the run is through walls, you either need to re-cable or use SFP+ with DAC/fibre instead.
Mistake 2: Forgetting the PC Side
A 10GbE NAS card only speeds up the NAS end. Your PC or Mac also needs a 10GbE connection. Most consumer motherboards only include 1GbE or 2.5GbE. You will need a 10GbE PCIe card for your desktop (for example, a used Intel X540-T1 or Mellanox ConnectX-3) or a Thunderbolt-to-10GbE adapter for a laptop. Forgetting this step and ending up with a 10GbE NAS connected to a 1GbE PC is surprisingly common.
Mistake 3: Expecting HDD Arrays to Saturate 10GbE
Four-bay HDD RAID 5 throughput varies substantially with the NAS, drives, RAID implementation and workload; use measured results for the exact configuration. Spending on 10GbE hardware (NAS card + switch) to access a spinning-disk NAS gives diminishing returns compared to the much cheaper 2.5GbE upgrade path. 10GbE shines with SSDs or with multiple simultaneous users.
Mistake 4: Mixing Up RJ45 and SFP+ Without Planning
RJ45 and SFP+ are not interchangeable without adapters. If your NAS card has RJ45 and your switch only has SFP+ ports (or vice versa), you need either an SFP+-to-RJ45 transceiver module (such as the Ubiquiti SFP+ Copper Transceiver) or a different card/switch combination. Plan your entire chain. NAS port, cable, switch port, cable, PC port. Before purchasing anything.
The Full 10GbE Upgrade Cost in Australia
Here is what a complete 10GbE upgrade actually costs in Australia, broken down by scenario. Verify live Australian retailer listings before purchasing.

Buying networking hardware in Australia: Your first step for a faulty product is usually the retailer that sold it. The ACCC explains your rights under the Australian Consumer Law at accc.gov.au. Manufacturer warranties may exclude parallel imports, and enforcing rights against an overseas seller can be difficult.
NBN and Remote Access: 10GbE Is a LAN Upgrade
A common misconception worth addressing: 10GbE has nothing to do with your internet speed. Upgrading to 10GbE improves transfers between devices on your local network. Your PC to your NAS, your Mac to your NAS, your NAS to another NAS. It does not make your NBN connection faster. On a typical NBN 100 plan, upload speeds are capped at roughly 20-40 Mbps (depending on technology and congestion). Current eligible FTTP and HFC Home Ultrafast services have a wholesale tier of approximately 1000/100 Mbps; Home Hyperfast reaches 2000/200 Mbps on FTTP and 2000/100 Mbps on HFC. Remote access to your NAS, Synology Drive sync, QuickConnect, and similar features are all limited by your NBN upload, not your LAN speed.
CGNAT prevents ordinary inbound IPv4 port forwarding, but relay services such as Synology QuickConnect and QNAP myQNAPcloud Link can still provide remote access, usually with performance limitations. Check with your ISP whether you have a public IPv4 address. This is a separate issue from 10GbE but worth noting if you are investing in your NAS setup.
Planning Your 10GbE Upgrade: Step by Step
If you have decided 10GbE is right for your workload, here is the operational sequence to follow. Getting this order wrong leads to wasted purchases and compatibility headaches.
Step 1: Verify your NAS supports 10GbE. Check your NAS model for a PCIe expansion slot (for example the Synology DS1825+, DS1823xs+ and DS3622xs+, or the QNAP TS-x64/x73A series and most rackmount models). The Synology DS1525+ has a network upgrade slot that takes only the E10G22-T1-Mini. If your NAS has no PCIe slot, the reliable options are a model with built-in 10GbE or a vendor-documented external adapter supported by that exact NAS and operating-system version; do not assume a generic USB-to-10GbE adapter will work.
Step 2: Decide between RJ45 and SFP+. RJ45 is simpler (standard Ethernet cables) but 10GbE RJ45 ports use more power and generate more heat than SFP+. SFP+ is cheaper for short runs (DAC cables are inexpensive) but requires SFP+ ports on all equipment. Most home and prosumer users should start with RJ45 for simplicity.
Step 3: Audit your cabling. For RJ45 10GbE: check that existing cable runs are Cat6 or Cat6a. For SFP+: DAC cables suit short links within a rack or desk; fibre optic handles longer distances. If re-cabling is needed, factor this into your budget and timeline.
Step 4: Choose your switching (or go direct). For a single NAS-to-PC connection, skip the switch and go point-to-point. For multiple devices, select a switch that matches your port type (RJ45 or SFP+) and budget.
Step 5: Order everything together. NAS stock and networking hardware availability can be inconsistent at Australian retailers. Ordering piecemeal risks having half a setup sitting idle while waiting for the other half. Check stock at Scorptec and PLE before ordering. Stock status and supplier lead times vary by retailer and product; confirm availability and a firm ETA before ordering.

Can I use 10GbE with my existing Cat5e house cabling?
No. Cat5e does not reliably support 10GbE. Cat5e is not specified to provide a guaranteed 10GBASE-T channel. A short existing run may establish a link, but reliable 10GbE performance is not assured and should be tested. For 10GbE over copper, you need Cat6 (up to 55 metres) or Cat6a (up to 100 metres). Cat5e is fine for 2.5GbE, which is why 2.5GbE is the more practical upgrade for most Australian homes with existing cabling.
Do I need a 10GbE switch or can I connect NAS to PC directly?
A direct point-to-point connection works perfectly for a single NAS-to-PC setup. Connect a 10GbE port on your NAS directly to a 10GbE port on your PC using a Cat6/Cat6a cable or SFP+ DAC cable. Assign static IPs on both interfaces. You still use your regular 1GbE or Wi-Fi connection for internet access. A 10GbE switch is needed when multiple devices must share the 10GbE network. A multi-interface NAS can also remain accessible over its ordinary LAN while maintaining a separate direct 10GbE link to one workstation.
Will 10GbE make my Plex streaming faster?
For a single Plex stream, 10GbE is overkill. Plex bandwidth depends on each file's bitrate and the number of simultaneous streams. Compare their aggregate bitrate with the available network capacity. 10GbE benefits Plex setups primarily when the server is also handling other workloads simultaneously (file transfers, backups, transcoding) or when you have an exceptionally large library and want faster metadata scanning. For pure Plex streaming, 2.5GbE is more than sufficient.
How much does a full 10GbE NAS setup cost in Australia?
A basic point-to-point setup needs a 10GbE adapter in the NAS (for example the Synology E10G30-T1, $264.96 at MegaBuy), a 10GbE card in the PC and a cable. Multi-device access adds a 10GbE switch such as the QNAP QSW-2104-2T-R2 ($269 at Scorptec) plus cabling. A business-grade setup with a multi-port 10GbE switch such as the Ubiquiti Pro XG 10-Port ($1,199 at MSY and UMart) also needs structured Cat6a cabling, which needs a site-specific quote. The cost is higher than 2.5GbE, but 10GbE delivers roughly 4x the throughput.
What is the difference between SFP+ and RJ45 for 10GbE?
RJ45 uses standard Ethernet cable (Cat6/Cat6a) and standard Ethernet ports. Familiar and easy to work with. SFP+ uses either fibre optic cables with transceiver modules or DAC (Direct Attach Copper) twinaxial cables. SFP+ advantages: lower power consumption, less heat, inexpensive short-range DAC cabling. RJ45 advantages: works with existing structured cabling, no special modules needed, more familiar for home users. The right choice depends on your infrastructure. If you already have Cat6a runs through the house, RJ45 is easier. If your NAS and switch are in the same rack, SFP+ with DAC is cheaper and cooler.
Does upgrading to 10GbE make my internet faster?
10GbE does not increase the speed provisioned by your internet plan, although multi-gigabit LAN ports may be needed to avoid a local bottleneck on internet services faster than 1Gbps. It speeds up transfers between your devices. PC to NAS, NAS to backup NAS, workstation to file server. Your internet speed is determined by your NBN plan and connection type. On a typical NBN 100 plan, uploads are capped at 20-40 Mbps regardless of your LAN speed. Current eligible FTTP and HFC Home Ultrafast services have a wholesale tier of approximately 1000/100 Mbps, subject to provider participation and service eligibility. Remote NAS access through Synology QuickConnect, QNAP myQNAPcloud, or VPN is always limited by your internet upload speed, not your LAN speed.

Is it worth upgrading from 2.5GbE to 10GbE?
It depends on your bottleneck. If you are a single user with an HDD-based NAS and 2.5GbE already delivers 280 MB/s real-world speeds close to your RAID array's capability, jumping to 10GbE provides marginal benefit at significant cost. If you are a video editor working with 4K+ footage, running an all-flash NAS, or sharing the NAS across multiple simultaneous users who collectively saturate 2.5GbE, the upgrade to 10GbE is justified. The cost difference between 2.5GbE and 10GbE varies with adapters, switching, cabling and existing equipment, and should be calculated for the proposed build.
