The right NAS speed for 4K editing is not determined by “4K” alone. It depends on the codec, frame rate, number of simultaneous clips, whether you edit native media or proxies, and whether one workstation or a team is pulling from the same storage.
For proxies and project archives, 1GbE can still be useful. A controlled solo workflow may work well on 2.5GbE, while high-bitrate native media, multicam timelines, and shared editing usually justify planning around 10GbE. The network port is only one part of the decision: the drives, client SSD, switch, and editing workflow must sustain the same path.
Start With the Timeline, Not the “4K” Label
Two 4K files can place completely different demands on a NAS. A compressed camera clip may be relatively light to read, while a 4K ProRes master, RAW sequence, or several synchronized camera angles can require far more sustained throughput. Resolution tells you how many pixels are in the frame; it does not tell you how quickly the editor needs to read media.
Begin with the footage you actually cut: codec, frame rate, colour format, number of active angles, and whether you use effects or color work that requires frequent timeline reads. Then add the number of people who may work from the NAS at the same time. That is a more reliable buying method than choosing a port because it has the largest number on the box.
Turn Footage Data Rate Into a NAS Read-Speed Target
Codec and frame rate set the starting point
The Apple ProRes white paper shows why codec details matter. At DCI 4K (4096 × 2160) and 24p, its published target rates range from 155 Mb/s for ProRes 422 Proxy to 1,131 Mb/s for ProRes 4444. These figures describe media data rate, not the complete bandwidth budget for a working edit.
| Example: DCI 4K at 24p | Published target rate | Approximate media read rate | Planning implication |
|---|---|---|---|
| ProRes 422 Proxy | 155 Mb/s | 19 MB/s | Low network demand; useful for proxy workflows. |
| ProRes 422 | 503 Mb/s | 63 MB/s | One stream is manageable, but headroom still matters. |
| ProRes 422 HQ | 754 Mb/s | 94 MB/s | Leaves little room on a 1GbE editing path. |
| ProRes 4444 | 1,131 Mb/s | 141 MB/s | Calls for a faster, well-balanced workflow. |
Build in headroom for real timeline work
A timeline rarely reads one file at one constant rate. Multicam editing, picture-in-picture, audio tracks, thumbnails, waveform generation, renders, and another editor’s activity all compete for throughput. Treat the calculated media rate as a starting point, then choose a network and storage layout with enough margin for peaks rather than targeting the exact number.
Choose 1GbE, 2.5GbE, or 10GbE by Editing Workflow
1GbE is best treated as an archive, transfer, or proxy-editing path. It can be useful when your project is designed around lightweight proxy files, but it has limited headroom for native high-bitrate footage or several active streams.
2.5GbE is a sensible step for a solo editor working with compressed media, modest ProRes timelines, or a proxy-first workflow. 10GbE becomes the more practical planning tier when you want to edit higher-bitrate native media, run multicam sequences, or give several workstations access to active projects. It is not a guarantee by itself: the NAS must be able to read from storage at the required rate.
| Editing situation | Network starting point | What to verify next |
|---|---|---|
| Archive, backup, or proxy editing | 1GbE | Proxy generation time and local cache space. |
| Solo editing with compressed 4K or moderate native media | 2.5GbE | Single-client NAS read speed and workstation Ethernet. |
| High-bitrate native media or frequent multicam work | 10GbE | Array throughput, NVMe workspace tier, and client SSD. |
| Multiple active editors | 10GbE or faster shared design | Per-user bandwidth, switch uplinks, and concurrent storage reads. |
A Fast Network Does Not Fix a Slow Editing Data Path
Storage throughput must match the Ethernet link
A 10GbE connection only helps when the NAS can serve data quickly enough. A small HDD pool may be excellent for capacity and archive media but struggle to feed multiple high-bitrate reads at once. An active-project SSD or NVMe tier can reduce that mismatch, while the HDD array remains the larger shared library.
Storage networking is an end-to-end design problem: the Arista storage networking white paper similarly frames performance around the complete path rather than one interface speed. NAS drives, RAID layout, client storage, Ethernet adapters, switch capacity, and background jobs all influence what the editor actually experiences.
Keep catalogs, caches, and scratch files in the right place
Shared source media belongs on the NAS; editing catalogs, application databases, cache files, and scratch disks often perform better on the editor’s local SSD. This keeps small, latency-sensitive operations close to the workstation while the NAS handles the large media assets it is designed to centralize.
That separation also explains why a 10GbE NAS can still feel slow with an HDD pool: a fast link cannot overcome a bottleneck elsewhere in the workflow.
Native Media vs Proxies Changes the Speed You Need
Native editing keeps the original camera files online and avoids an extra transcode-and-relink stage. It is attractive when you need immediate access to high-quality source media, but it raises the sustained throughput requirement for both the NAS and the network.
A proxy workflow creates smaller editing files while preserving the originals for finishing and export. It can make a 1GbE or 2.5GbE setup productive for projects that would otherwise call for a much faster shared-storage design. The trade-off is preparation time, storage for proxy files, and careful media relinking.
Choose proxies when they simplify the entire workflow, not only because the current NAS is slower. Choose native editing when the format, collaboration pattern, and available storage path can support it with useful headroom.
One Editor and a Team Do Not Need the Same NAS Design
Solo editing: optimize one complete path
A solo editor can focus on one wired workstation, one NAS connection, and one active-project storage tier. This is often the most cost-effective place to move from 1GbE to 2.5GbE or 10GbE, because only one user needs predictable access to the full available bandwidth.
Shared editing: budget throughput per workstation
Teams need to account for simultaneous media reads rather than a single speed test. A 10GbE NAS port is shared capacity, not 10GbE guaranteed to every editor. The switch, NAS uplink, drive pool, and each client connection should be planned around the number of people and their active formats.
If you are still choosing the broader architecture, whether a shared NAS or direct-attached workspace better fits the way you edit is often the decision to make before sizing the network.
A Practical ZimaCube Path for 4K Editing
For a creator who needs shared capacity and a faster active workspace in one system, ZimaCube 2 is a practical fit when the workflow benefits from separating large media storage from current projects. Its hardware overview documents six SATA drive bays and four M.2 NVMe bays, allowing the storage layout to reflect those two jobs instead of forcing every file onto one type of drive.
A sensible setup is to keep the wider footage library on a protected HDD pool, place active projects or proxy media on NVMe storage, and connect editing workstations over the network tier that matches the calculated workload. Start with 2.5GbE when the project and storage path support it; move to 10GbE when native media, multiple streams, or collaborators make the extra headroom valuable.
Do not choose a ZimaCube 2 solely because you edit 4K. Choose it when you need its mix of expandable SATA capacity and NVMe workspace options, and when the rest of your network can make use of that storage design.
FAQ
Is 1GbE enough for 4K video editing?
It can be enough for proxy workflows, archives, and some lower-demand single-stream projects. It is less comfortable for high-bitrate native media, multicam work, or shared editing because there is little room for peak demand.
Is 2.5GbE enough for a solo editor?
Often, yes—especially for compressed 4K footage, proxies, or a controlled native-media workflow. Confirm that the NAS drives and the workstation can sustain the needed speed before treating 2.5GbE as the answer.
Does 10GbE guarantee smooth 4K editing?
No. It provides more network headroom, but smooth editing still depends on the NAS storage pool, switch, client adapter, local cache location, codec, and number of simultaneous streams.
