Quick answer: 2.5GbE is enough when the actual concurrent edit workload stays under a conservative 250 MB/s planning ceiling and the array and each client can sustain it. Move to 10GbE when originals, multicam, several editors or transfer windows push beyond that margin. Do not upgrade the network first if the measured array is slower than the workload, a client only has 1GbE, or proxies solve the editing problem more cheaply.
For shared 4K workflows, Adobe’s current guidance points to 10GbE; it also says to keep Media Cache on a local SSD. That is a workflow recommendation, not a promise that every 4K codec or NAS will perform the same way.
Video editing network calculator
Only the inputs below affect the result. It calculates locally in the browser and does not send codec choice, project names, filenames, calculated values or workstation details to TPTK analytics.
Demand MB/s = bitrate Mbps ? 8 ? streams/editor ? editors ? proxy factor ? (1 + safety margin). Current ceiling = smallest of client port ? 125 ? 0.8, existing network ? 125 ? 0.8, and measured array MB/s.
The 80% network budget and visible safety margin are TPTK planning assumptions. Line rate is not realized throughput; confirm switch, cable, NIC, adapter and protocol behavior before purchase.
What each Ethernet tier actually means
HD and proxy floor
Use it for light HD, proxy editing or an individual shared project. At a 100 MB/s planning ceiling, one heavy original stream can already be uncomfortable.
Good small-team bridge
Its 250 MB/s planning ceiling suits many proxy workflows and a few moderate original streams when the array also clears the demand.
Do not read 2.5GbE as a per-team guarantee: concurrent editors share the NAS uplink.
Useful middle tier
A 500 MB/s planning ceiling is a rational upgrade where client and switch hardware support it, but it is not automatically cheaper than a clean 10GbE path.
Shared 4K default
A 1,000 MB/s planning ceiling gives room for several editors, originals and transfers, subject to the single NAS uplink and the measured array.
When the original is the problem
Proxies lower active editing demand without pretending the network or disks are faster. Keep originals protected and test the proxy/relink workflow.
When a faster port changes nothing
If the existing ceiling clears the model with a sensible margin, allocate budget to backup, storage capacity or local cache instead.
Check the bottleneck in this order
1. Client link
A 1GbE workstation cannot consume a 10GbE NAS link. Confirm native Ethernet, dock bandwidth and adapter support before buying a switch.
2. NAS/switch uplink
Several fast clients can still share one uplink. Link aggregation may distribute clients but does not turn every single transfer into a combined-port transfer.
3. Array throughput
Use a measured sustained read result. A four-bay HDD array, parity layout, fragmentation and concurrent seeks can be slower than the port label.
4. Local cache
Premiere recommends local Media Cache. Do not move cache onto the share merely because the NAS link looks fast.
5. Workflow
Multicam and simultaneous exports create demand patterns that a single bitrate number misses. Count streams and concurrent editors explicitly.
Useful next steps
Capacity and bitrate sources
Use the storage calculator for camera presets, multiple source rows and backup capacity.
Single-editor active media
A direct external SSD may be the cleaner solution before a shared-storage build.
Editing workstation constraints
Codec decode, local NVMe and GPU requirements remain a separate decision.
Protect the project
Shared editing storage is not an offsite backup or a restore test.

Frequently asked questions
Is 2.5GbE enough for 4K video editing?
Sometimes. It depends on the actual bitrate, concurrent streams, editor count, safety margin, client ports and sustained array read speed. A 4K label alone cannot answer it.
Why is 10GbE commonly recommended for shared 4K editing?
Adobe’s current shared-storage guidance recommends 10Gbps or faster for larger-than-HD frame sizes, larger Productions and multiple simultaneous users. It still requires a capable client and storage array.
Will a 10GbE NAS make a 1GbE computer faster?
No. The 1GbE client link remains the ceiling until the computer has a compatible faster port or adapter and the rest of the path supports it.
Should I use proxies instead of upgrading the network?
Use proxies when they make editing reliable at a lower cost and fit the team’s ingest and relink process. They do not replace backup or capacity planning for original footage.
Does dual 10GbE mean 20GbE for one editor?
Not normally. Two ports can help distribute separate clients or support a specific topology, but a single client flow and link-aggregation behavior depend on the hardware and configuration.
