2TB External SSD Explained: A UK Buyer's Guide

Short answer: a 2TB external SSD is the fast choice for editing directly off the drive, but for archiving delivered RAW photos and finished video it is expensive for what you need. A 2TB hard drive gives the same capacity for far less, which is why many photographers keep an SSD as the working drive and a hard drive as the archive.

If your internal drive keeps filling with RAW photos and finished videos, the real question is not just SSD versus hard drive — it is which job each one does. This guide weighs the speed you actually need against the cost of keeping a second copy of client work.

Working drive or archive drive?

The two roles have very different needs. A working drive is where you cut current projects, so speed matters and an SSD earns its price. An archive drive holds finished, delivered work you rarely open, where capacity and cost per terabyte matter far more than raw throughput.

Once a batch of client photos or a video project is delivered, moving it off an expensive SSD working drive onto a cheaper 2TB archive keeps the fast storage free for the next job — without letting archive costs run away.

Is 120 MB/s fast enough for backups and archiving?

For copying finished files across and storing them, a hard drive's ~120 MB/s is perfectly workable — you set a large transfer going and let it run. Where it shows its limits is scrubbing through 4K timelines or shifting huge libraries all day; that is when an SSD's speed genuinely changes the workflow. Be realistic about which of those you actually do before paying the SSD premium.

HDD versus SSD on cost per terabyte

This is the number that decides most archive setups. Portable hard drives sit at roughly a few pence per gigabyte, while SSDs cost several times more for the same space. Across multiple 2TB archives, that difference adds up quickly — so paying SSD prices to store footage you rarely touch is money that could fund another backup copy instead.

How much RAW and video fits on 2TB?

As a rough planning figure, 2TB holds tens of thousands of RAW stills, or roughly 30–40 hours of 4K footage, or far more 1080p. Usable space is a little under the headline 2TB after formatting, and 4K projects eat capacity fast, so size your archive for the projects you actually keep rather than the drive's label.

Why one drive is never enough for client work

A single drive — SSD or hard drive — is one drop or failure away from losing a delivery. Keep client footage on at least two drives, ideally with one stored away from your desk. For a small, portable SSD to pair with a larger archive, see our 500GB external SSD guide, and for choosing the archive drive itself our portable hard drive buying guide.

The 2TB hard drive alternative for archiving

As the archive half of that pairing, the BackupDrive 2TB Portable External Hard Drive keeps delivered projects safe without SSD prices. It offers 2TB over USB 3.0 Micro-B (up to 120 MB/s), is USB bus-powered so there is no power brick to pack, weighs 168 g, and includes data rescue support with a 12-month UK warranty. It works with Windows 10/11 and macOS 10.12 and later, is £96.26 inc. VAT with free UK delivery and 30-day returns, and is rated 4.7 out of 5 from 320 reviews.

Frequently asked questions

Is a 2TB external SSD worth it over a hard drive?

For editing directly off the drive, yes, because an SSD is far faster. For archiving delivered RAW photos and video you rarely reopen, a 2TB hard drive gives the same capacity for much less, which is why many photographers use an SSD working drive and a hard drive archive.

Is 120 MB/s fast enough for video backups?

For copying finished files across and storing them, a hard drive's roughly 120 MB/s is fine, since you start a large transfer and let it run. For scrubbing 4K timelines or moving huge libraries all day, an SSD's higher speed makes a real difference.

How much RAW and video fits on 2TB?

As a rough guide, 2TB holds tens of thousands of RAW stills or around 30 to 40 hours of 4K footage, and far more 1080p. Usable space is slightly under 2TB after formatting, and 4K projects use capacity quickly.

Can I store client work on just one drive?

No. A single drive, SSD or hard drive, is one failure away from losing a delivery. Keep client footage on at least two drives, ideally with one stored away from your desk as an offline copy.
