Best Hard Drives for Photo Storage

A 45 MP camera shooting RAW produces roughly 50–80 MB per frame. At 500 shots per shoot and two shoots a week, that is 2.5–4 TB of originals per year before edits, exports, or video. Most working photographers need at least 8 TB today with room to grow; if you keep every original (you should), plan for 12–20 TB within a few years. Buy more than you think you need — drives are usually cheaper per TB at higher capacities, though that relationship is less predictable in the 2026 shortage market, so check the live $/TB table before committing to a size.

CMR for a primary working drive. Lightroom and Capture One generate heavy random read traffic when building previews and serving catalog queries — CMR handles this well. SMR drives throttle under that random-write/read pattern and can become noticeably sluggish during catalog operations. For a cold archive you rarely access, SMR is fine and is sometimes cheaper per TB.

A desktop external HDD is enough for a solo photographer editing from one machine. A NAS adds value when you edit from multiple computers, want always-on network access to your library (useful with Synology Photos or Lightroom smart previews), or need a proper 3-2-1 backup target. NAS hardware adds cost; if the simpler setup meets your workflow, start there and upgrade later.

Three copies of your files, on two different media types, with one copy off-site. In practice for photographers: your main archive drive, a second backup HDD stored at home, and an off-site copy — either a drive you rotate to another location or cloud storage. No single drive is a backup. The cost of an extra high-capacity HDD is trivial compared to re-shooting a wedding.

A 2.5-inch bus-powered portable HDD (up to 5 TB) works well for backing up memory cards in the field. For cinema RAW that generates several hundred GB per day, consider two portable drives and copy simultaneously — never rely on a single copy of irreplaceable footage.
