Storage planning is less about finding the biggest number on a box and more about measuring what you already keep. Photos, video, desktop backups and project folders expand at different rates. A useful NAS capacity plan starts with present usage, accounts for versions and growth, then leaves an independent path for recovery outside the main device.

Quick Answer

Add your current photo, video and computer backup totals, then allow room for versions and at least three years of growth. Calculate usable space after the chosen protection layout, and keep a separate copy outside the NAS. The R8,499 UGREEN NASync DXP2800 is diskless and can support up to 80TB, but SSD or HDD drives must be selected and installed separately.

📊 Build a measurement sheet before choosing drives

Open the storage view on every computer and phone that will feed the NAS. Record broad categories rather than only the grand total: photographs, raw video, edited exports, documents, application backups, music, downloads and shared files. A full system backup can include temporary material that does not need long-term retention, so note whether each category is meant to be preserved, versioned or cleaned regularly.

Measure the rate of change for a few months if possible. A household that takes several phone photos a day may have steady growth. A creator who imports 4K footage can add a large amount after a single shoot. A small business may hold mostly documents yet need several retained versions. Capacity follows behaviour, not just the number of users.

The hard drive category is relevant once this total is known. It is much easier to compare storage options when the target is expressed as usable capacity with a growth allowance, rather than raw capacity without a purpose.

🧮 Translate raw drive space into usable room

Installed drive capacity is not identical to the space available for files. The file system takes some room, and a layout that keeps data available after a drive failure may reserve capacity for that protection. In a two-drive mirror, the smaller drive commonly determines the usable ceiling. A layout that combines capacity across drives may offer more room but accepts a different failure trade-off.

Write down two figures for every candidate layout: raw total and usable estimate. Then add a buffer for temporary ingest, deletion recovery and backup versions. Filling a NAS to its limit makes organising, checking and moving data harder, particularly when a future drive replacement is required.

The UGREEN NASync DXP2800 has an 80TB storage capacity. Treat that as an upper boundary for planning, not a promise that 80TB will be free for files. The diskless NAS storage category can help compare the enclosure choice alongside the media required to make it useful.

🧹 Reduce waste before expanding

When space feels tight, first identify duplicates, accidental copies and obsolete downloads. Do not remove material simply because it looks old. Start with clearly disposable files, then use folders, dates and project names to identify repeated exports or temporary working files. Keep a recovery copy before removing anything that might be needed later.

Retention rules make future growth more predictable. Decide how long to keep phone imports, finished edits, system images and old project versions. A clear rule such as keeping final exports and selected source material is safer than periodically deleting in panic. It also prevents the NAS from becoming a second version of every device's clutter.

Solid-state storage can suit workflows where responsiveness or compact media is important, while hard drives may be chosen for broad archive capacity. The SSD category provides another option to compare against the work being done. The right mix is determined by the data, compatibility guidance and budget, not by one universal rule.

🧳 Keep recovery outside the capacity calculation

The NAS should not be the only destination for the files it protects. A separate copy prevents one device problem from becoming the only recovery option. Decide where it will live, how it will be updated and how long recovery would take. That last question is often missed: a backup that takes weeks to retrieve may not meet a working project's needs.

Test a restore before declaring the plan complete. Restore a photo library sample, a document folder and a larger backup item to another location. Check that the files open, the dates make sense and the expected versions are present. This converts a capacity plan into a recovery plan.

📅 Review the forecast before storage becomes urgent

Put a reminder in the calendar to review usage every few months. Compare actual growth with the original estimate and note any new source of large files, such as a camera upgrade, a new workstation or a shared project. A calm review gives time to prepare an expansion rather than copying data under pressure.

Keep the same measurement categories at each review. If video is growing faster than expected while documents remain stable, the next storage decision is clearer. When a drive change is planned, update the capacity sheet and repeat a restore test after the layout is settled.

🧾 Turn a folder total into a capacity decision

Make a short inventory before selecting drives. Record the current size of photos, video, computer backups and shared work separately, then add the amount created in a typical month. For example, a 2TB library growing by 50GB each month adds about 1.8TB over three years before versions, duplicate imports and fresh device backups are counted. The purpose is not to predict every file perfectly; it is to avoid buying from an empty starting point.

Then calculate the usable figure for the protection layout you intend to use. Two drives with the same raw capacity do not automatically provide the sum of both drives if the layout is designed to tolerate a drive failure. Add a margin for temporary copy jobs and keep the outside backup separate from the NAS capacity calculation. Revisit the table after several months. If video work or PC backups are growing faster than expected, an early plan for expansion is easier than moving a full archive under pressure.

Frequently Asked Questions

How much free room should a NAS keep?

Leave a practical buffer for new imports, versions and maintenance. The exact margin depends on workload, but a plan that runs permanently at the limit has little room for safe housekeeping.

Why is usable capacity lower than the drive labels add up to?

Formatting and the chosen protection layout affect what can be used for files. A resilient layout may deliberately reserve capacity to tolerate a drive problem.

Should photos and PC backups be counted separately?

Yes. They grow differently and may have different retention needs. Separate figures make it easier to decide what requires frequent copies or longer history.

Is a NAS backup enough on its own?

No. Keep an additional copy away from the NAS and test restoring files from it.
