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 these 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. A 4-drive RAID 5 with HDDs typically tops out at 400-500 MB/s sequential, which 2.5GbE (280 MB/s real-world) covers for most single-user workloads
- You want a meaningful speed boost without re-cabling your house or spending $500+ on 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 barely matters on Gigabit, since a single mechanical hard drive already tops out around 100-120 MB/s, close to what 1GbE can carry anyway. 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 E10G18-T1 |
|---|---|
| Type | Single-port 10GbE RJ45 (copper) |
| Interface | PCIe 3.0 x4 |
| Compatible NAS | DS1825+, DS1823xs+ (E10G18-T1); DS1525+ (E10G22-T1-Mini); RS models (model-specific compatibility only) |
| AU Price (Mwave) | $239 |
| AU Price (Scorptec) | $269 |
The E10G18-T1 is the go-to 10GbE card for Synology NAS owners. It uses RJ45 copper, which means you can connect it with standard Ethernet cables (Cat6 minimum). Plug-and-play in DSM. No driver installation required. The E10G18-T1 is an EOL adapter that remains available from some retailers. Verify the current supported adapter and live price for your exact Synology model before purchasing. Compatibility is model-specific; confirm the E10G18-T1 against Synology's compatibility list for the exact NAS model before purchasing.
| Model | Synology E10G30-F2 |
|---|---|
| Type | Dual-port 10GbE SFP+ |
| Interface | PCIe 3.0 x8 |
| Use Case | Link aggregation, failover, fibre connections |
| AU Price (Mwave) | $459 |
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. At $459, it costs nearly twice the E10G18-T1. It only makes sense if you need SFP+ specifically (matching your switch infrastructure) or need two ports. For most home and prosumer setups, the E10G18-T1 is the better buy.
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. |
| AU Price (Scorptec) | $649 (currently out of stock) |
QNAP's QXG-10G2T-X710 is a dual-port 10GbE card built on the Intel X710 chipset, which also supports SR-IOV for virtualisation workloads on QNAP's Virtualisation Station. At $649, it is significantly more expensive than Synology's single-port E10G18-T1, but it gives you two 10GbE ports and advanced features. QNAP also offers single-port 10GbE and 5GbE cards, though availability varies at Australian retailers. Stock can be inconsistent due to lower volumes through the distribution channel.
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.
10GbE Switch Options. AU Pricing
| QNAP QSW-2104-2T | QNAP QSW-1105-5T | Ubiquiti Flex Mini 2.5G | Ubiquiti Flex 2.5G 8-Port | Ubiquiti Pro XG 10-Port | |
|---|---|---|---|---|---|
| 10GbE Ports | 2x SFP+ | None (2.5GbE only) | None (2.5GbE only) | None (2.5GbE only) | 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) |
| AU Price | $299 (Scorptec, OOS) | $159 (Scorptec) | $109 (Scorptec) | $329 (PLE) | $1,489 (PLE) |
| Best For | NAS to workstation via SFP+ | Budget 2.5GbE for NAS | Compact 2.5GbE segment | Multi-device 2.5GbE segment | Business/prosumer full 10GbE |
The QNAP QSW-2104-2T is the sweet spot for Australian NAS owners who want 10GbE without enterprise pricing. 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 $299, it is a relatively affordable Australian option for two 10GBASE-T RJ45 ports plus four 2.5GbE ports. When it is in stock. Stock has been inconsistent through BlueChip and Dicker Data distribution, so check availability before planning your build around it.
For full 10GbE switching across multiple ports, the Ubiquiti UniFi Pro XG 10-Port at $1,489 (PLE) 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 all 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). A Ubiquiti 0.5m SFP+ DAC cable costs $39 from Scorptec., and a 1m cable is $39. For a working point-to-point link, both adapters must use matching media: pair the E10G18-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 from Scorptec or PLE for $10-$20 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, cheap, and low-latency. But limited to short distances (typically 1-3 metres, with some 5m options). A Ubiquiti 0.5m SFP+ DAC costs $35 and a 1m costs $39 from Scorptec. 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 5 metres between SFP+ devices, fibre optic cables with SFP+ transceivers are the standard approach. Multimode fibre (OM3/OM4) supports 10GbE up to 300 metres, and single-mode (OS2) goes much further. The cables themselves are inexpensive ($15-$40), but each end needs an SFP+ transceiver module ($30-$80 each depending on brand). 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 |
| AU Price (PLE) | $1,699 |
| AU Price (Mwave) | $2,567 |
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. At $1,699 from PLE, it offers strong value for a built-in 10GbE NAS. Compare that to buying a separate NAS plus a $239-$269 10GbE card, and the TS-h973AX comes out ahead on features.
| 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 Price (PLE) | $3,799 |
| AU Price (Mwave) | $3,057 |
The TVS-672XT is QNAP's premium creative workstation NAS with both 10GbE and Thunderbolt 3. Thunderbolt 3 allows direct connection to a Mac or PC at up to 40 Gbps, while 10GbE serves the rest of the network. At $3,057-$3,799 it is a serious investment, and the hardware platform is ageing. Unless you specifically need Thunderbolt 3 connectivity, the TS-h973AX offers better value for most 10GbE use cases.
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) at $1,699-$1,720 includes 10GbE and is designed as an all-flash 6-bay M.2 NAS. The Flashstor 12 Gen2 (FS6812X) at $2,399-$2,408 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, but they represent the highest raw throughput per dollar if your workflow demands all-flash speeds.
Synology Models with 10GbE Options
Synology does not currently ship consumer or prosumer desktop NAS models with built-in 10GbE. Their approach is to offer PCIe expansion cards (E10G18-T1, E10G30-F2) for Plus and XS series models. Built-in 10GbE is also available on desktop DiskStation models, including the DS1823xs+ with one 10GbE RJ45 port and the DS3622xs+ with two 10GbE ports., which start at ~$6,531+. For most Synology users, the path to 10GbE is a Plus or XS model with a PCIe slot plus the E10G18-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.
Real-World 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. That exceeds 2.5GbE (280 MB/s real-world) but falls well short of saturating 10GbE (1,100 MB/s). 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 (the file-sharing protocol used by Windows and Mac to access NAS shares) introduces overhead that reduces raw throughput by 5-15% depending on file sizes. 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
After helping NAS owners troubleshoot networking issues, certain patterns emerge repeatedly. These are the 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 (around $50-$100 for a used Intel X540-T1 or Mellanox ConnectX-3 from eBay) or a Thunderbolt-to-10GbE adapter for a laptop ($200-$350). 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
As shown in the throughput table above, a 4-bay HDD RAID 5 array tops out at roughly 400-500 MB/s. That is 3-4x faster than 1GbE and nearly 2x faster than 2.5GbE, but still less than half of 10GbE capacity. Spending $700+ 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 (like the Ubiquiti SFP+ Copper Transceiver at $139 from Scorptec) or a different card/switch combination. Plan your entire chain. NAS port, cable, switch port, cable, PC port. Before purchasing anything.

Australian Consumer Law protections apply when purchasing networking hardware from Australian retailers. This covers faulty PCIe cards, switches, and transceivers for a reasonable period regardless of the manufacturer's stated warranty. ACL consumer guarantees generally apply to goods sold by Australian businesses, including parallel imports, and to overseas businesses selling directly to Australian consumers. 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 (Synology Plus/XS series, QNAP TS-x64/x73A series, most rackmount models). If your NAS has no PCIe slot, your options are: buy a NAS model with built-in 10GbE (QNAP TS-h973AX, Asustor Flashstor Gen2), use USB-to-10GbE adapters (limited performance), or accept that 2.5GbE is your ceiling.
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 cost $35-$39) 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 handle runs up to 3-5m, 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, PLE, and Mwave 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 (NAS card + PC card + cable) can be done for $310-$350 on top of your existing NAS. With a switch for multi-device access, budget $600-$800 more (QNAP QSW-2104-2T at $299 plus cabling and a PC-side card). A full business-grade setup with a multi-port 10GbE switch like the Ubiquiti Pro XG (from $1,489) plus cabling can reach $2,000-$2,500 before the NAS itself. The cost is higher than 2.5GbE (which can be done for under $200 total) but 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, cheaper short-range cabling (DAC cables from $35). 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.
