NAS for Video Editing 2026: Throughput, 10GbE & the Right RAID
· Last verified July 2026
If you edit video, your storage problem looks nothing like a photographer's, even though you both shoot the same cameras. A photo library is thousands of small random reads that stress latency; a timeline is a handful of big files streamed in order, and what breaks is throughput: the megabytes per second the pool and the network can deliver without the playhead stuttering. Get that one number right and everything else falls into place, so let's start there rather than with drive brands.
Why video editing is a bandwidth problem, not an IOPS problem
The reason this distinction matters is that it changes what you spend money on. A NAS built for photography wants low latency and often an SSD tier for the catalog, because Lightroom scrubbing through 40,000 thumbnails is a storm of tiny random reads; that's an IOPS workload, and we cover it in the sister guide on planning a NAS for photographers. Video is the opposite. When you scrub a 4K timeline the drive is handing you one long, mostly sequential file, so raw sequential MB/s is the metric, and spinning disks are surprisingly good at it: a single 7200 RPM CMR drive sustains roughly 200-260 MB/s on the outer tracks, and a four-drive parity array stripes several of those together.
That has a liberating consequence: for most editors the hard drives are not the bottleneck at all. A four-bay RAID 5 pool can comfortably read past 500 MB/s sequentially, which is far more than a single editing stream needs and more than a 2.5GbE link can even carry. The thing that actually throttles you sits between the NAS and your machine (the network), which is why the rest of this guide spends more time on Ethernet than on platters. The takeaway to carry forward: size the network to your codec first, and only worry about the disks when you move to RAW or many simultaneous editors.
Map your codec to the MB/s the NAS has to sustain
Every codec has a data rate, and dividing it by eight turns bits-per-second into the megabytes-per-second your storage has to feed per stream. This is arithmetic, not a benchmark, so you can do it for your own footage in a minute. Apple publishes ProRes target data rates and the figures below come straight from the Apple ProRes data-rate table, while delivery codecs like H.265/HEVC, the efficient compressor behind most camera and streaming files, run an order of magnitude lighter, as the HEVC overview lays out.
Here is what one video stream actually asks of the pool, rounded and paired with the network tier that carries it with headroom to scrub:
- Consumer 4K H.265 / H.264 (~100-150 Mbps) → ~13-19 MB/s. A single stream fits inside 1GbE with room to spare; this is most hobby and run-and-gun footage.
- ProRes 422 LT, 4K30 (~350 Mbps) → ~44 MB/s. Two or three streams still sit inside 2.5GbE.
- ProRes 422, 4K30 (~500 Mbps) → ~63 MB/s. Comfortable on 2.5GbE; tight on 1GbE the moment you add a second angle.
- ProRes 422 HQ, 4K30 (~750 Mbps) → ~94 MB/s. One stream nearly saturates 1GbE on its own; this is where gigabit stops being enough.
- ProRes 422 HQ 4K60 or ProRes 4444, 4K30 (~1.1-1.5 Gbps) → ~140-190 MB/s. Past 2.5GbE for anything beyond a single clip; 10GbE for multicam.
- 8K ProRes or camera RAW (BRAW, ProRes RAW, R3D) → several hundred MB/s to >1 GB/s. Firmly 10GbE territory, and often flash rather than spinning disks.
The practical move is to multiply your worst-case stream by the number of angles you cut simultaneously, then add a rough 30% for the scrubbing, caching and thumbnail traffic an NLE generates on top of playback. A three-angle ProRes 422 multicam at 4K30 is already 3 × 63 ≈ 190 MB/s before overhead, which tells you, before you've bought anything, that this project needs 10GbE and gigabit was never in the running.
The network is the real gate: 1GbE vs 2.5GbE vs 10GbE
Because the pool is rarely the limit, the Ethernet port is where editing NAS builds are won or lost, and the three tiers map cleanly onto the codec math above. Plain gigabit tops out near 113 MB/s in practice, which the ProRes 422 HQ line just showed is a single-stream ceiling: fine for H.265 proxies, hopeless for real multicam. Stepping to 2.5GbE lifts you to roughly 280 MB/s over the Cat 5e already in your walls, which is the sweet spot for a solo 4K editor and the upgrade most people should make first; the practical case is laid out in the 2.5GbE NAS upgrade guide.
10GbE is the tier that unlocks the heavy end, delivering around 1,100 MB/s in the real world (enough to stream RAW, run multicam ProRes, or serve several editors from one pool), and it's the reason serious edit NASes ship with an SFP+ or 10GBASE-T port. The standard itself is mature and cabling is undemanding at short home runs, as the 10 Gigabit Ethernet reference notes; if you're weighing the jump, the 10GbE NAS upgrade guide covers switches, NICs and the real-world numbers. The rule that saves money: match the port to your heaviest routine project, not to a codec you'll touch once a year.
A tempting shortcut is to bond two 2.5GbE ports with LACP link aggregation and call it 5 Gigabit, but that isn't how a single editor experiences it. A LACP bond hashes each TCP connection onto one physical link, so a lone file copy or a single playback stream never exceeds one port's speed; aggregation only helps when many separate flows run at once, as the link aggregation article explains. SMB Multichannel, introduced with SMB 3.0 and described in the Server Message Block overview, does the opposite: it stripes one session across multiple NICs and receive queues, so a single large read can actually exceed one link. If your NAS and workstation both support it, two 2.5GbE ports with SMB Multichannel can beat the same two ports in an LACP bond for a solo editor: a genuinely useful trick, but seasoning on top of simply buying a 10GbE card if the budget is there.
Editing off the NAS vs archiving to it: two different builds
People search "NAS for video editing" meaning two very different things, and conflating them is why so many builds disappoint. In the first, you edit directly off the NAS: the media lives on the pool, every editor mounts the same share, and the network has to carry live playback; this is the bandwidth build the sections above describe, where 2.5GbE or 10GbE and proxy workflows do the heavy lifting. When a codec is too heavy to stream comfortably, most NLEs let you generate lightweight proxies to edit against and relink to the originals at export, which is how a modest network survives ProRes HQ or RAW sources.
In the second pattern the NAS is a project archive and backup, not a scratch disk. You cut off a fast local NVMe or a Thunderbolt SSD, then push finished projects and camera originals to the NAS for safekeeping and long-term capacity. Here network speed barely matters (a nightly sync over gigabit is fine), and what you actually care about is terabytes per euro, parity that survives a drive failure, and an off-site copy, because RAID alone protects against exactly one thing. If that framing is new, why RAID is not a backup is worth five minutes before you trust a single array with masters. The honest takeaway: decide which build you're doing before you buy, because the archive job is cheaper and the editing job is faster, and the hardware that's ideal for one is over- or under-spec'd for the other.
Which RAID fits editing, and when flash earns its price
For a spinning-disk media pool the goal is read bandwidth plus survivable rebuilds, and that points at parity RAID for most people. RAID 5, Synology's SHR-1 or ZFS RAIDZ1 stripe reads across N-1 drives, so a four-bay pool reads fast enough to overrun 2.5GbE while giving back only one drive of capacity, the sweet spot the calculator preset at the top compares. Once you run five or more drives at 16 TB and up, step to RAID 6, SHR-2 or RAIDZ2, because a multi-day rebuild on large disks raises the odds of a second failure or an unrecoverable read error mid-repair; Backblaze's Q1 2025 Drive Stats put 16-22 TB annualized failure rates in the 0.9-1.7% band (source), low but not low enough to gamble a masters pool on single parity.
RAID 10 is the option editors reach for when they write heavily onto the pool or want the shortest possible rebuild, since it mirrors rather than recalculates parity; the trade is 50% usable capacity, which is expensive when a media library only grows. The full comparison lives in RAID 10 vs RAID 6, but for a mostly-read editing pool RAID 6 usually wins on cost-per-terabyte. Flash enters the picture only at the top: when you cut 8K, camera RAW or dense multicam directly, a spinning pool runs out of per-stream throughput and latency, and an NVMe or all-flash scratch volume becomes the working disk while the HDD parity pool demotes to archive tier. The OpenZFS project documents how a fast special or cache vdev fits a pool in its workload tuning notes, and the broader HDD-versus-flash trade is weighed in HDD vs SSD for a NAS. The decision rule: parity HDD for the library, flash only for the footage you're actively scrubbing at the extreme end.
Drives and network gear that fit an edit pool
Recommendation by use case
The hobbyist cutting single-angle 1080p or 4K in H.265 barely stresses anything: a 4-bay box with 4×16 TB in RAID 5 or SHR-1 and a 2.5GbE link edits smoothly, and gigabit even copes for proxies. Spend the saved money on an off-site backup rather than a faster network you won't saturate, and lean on the best 16 TB NAS drive shortlist for the platters. This is also the tier that overlaps with a media server, so the Plex storage guide pairs naturally if the same box streams your library.
The serious enthusiast or part-time pro cutting 4K ProRes 422/HQ wants 2.5GbE at minimum and should budget for 10GbE if multicam or 4K60 is routine: a 4-bay Ugreen DXP4800 Plus or a similar Intel box with a 10GbE port, 4×16-18 TB in RAID 5, and proxies for the heaviest sources. This is the build where the network, not the drives, decides whether playback is glassy, which is exactly why the product cards above weight toward the 10GbE trio.
The full-time studio or anyone cutting 8K, camera RAW or dense multicam should run a 6-bay-plus box with dual 10GbE, an NVMe or all-flash scratch volume for active footage, and a RAIDZ2 or SHR-2 HDD pool as the masters archive; a Ugreen DXP6800 Pro with 2×10GbE or a comparable TrueNAS build fits. Pair it with a second copy off-site, because a fire or a ransomware event takes the whole array regardless of parity, and no RAID level has ever restored a lost master. If the box itself isn't chosen yet, the best 4-bay NAS guide covers the class most editors land on.
