Portable SSDs for Backups: Real Brands, and a Scam Worth Knowing About

A genuine 1TB portable SSD from an established brand costs roughly £90-135 in the UK right now. A listing offering 2TB for £17 isn't a deal, it's very likely mislabelled storage.

  • Three real 1TB portable SSDs from established brands compared
  • The fake-capacity SSD pattern to watch for
  • How to verify actual storage capacity before or after buying

A 2TB SSD for £17-20 is very likely a capacity scam, not a deal

Genuine 1TB portable SSDs from established brands run roughly £90-135 in the UK right now. Unbranded listings claiming 2TB or higher at a fraction of that price are a well-documented pattern: the drive’s firmware reports a fake, inflated capacity, and it silently corrupts data once you exceed the drive’s real, much smaller storage. This isn’t a rare edge case; it’s a common scam pattern specifically on generic, unbranded portable storage listings.

Editorial take

How to Check a Drive's Real Capacity

If you've already bought an unbranded drive and want to verify its real capacity, free capacity-testing tools exist that write and verify data across the drive's full claimed size, which will expose a fake capacity quickly rather than waiting to discover corrupted backups later. For a genuine backup drive specifically, the safer approach is buying from an established brand in the first place, where this fraud pattern essentially doesn't occur, rather than relying on after-the-fact verification.

Best for
Anyone wanting a genuinely trustworthy 1TB backup drive Buyers who've been burned by or want to avoid capacity-fraud listings
Not for
Anyone needing more than 1TB on a single drive without paying a genuine branded 2TB price Buyers relying on a single backup drive as their only copy of important data
Pros
  • All three picks are from established, verifiable storage brands with genuine 1TB capacity
  • USB-C connectivity across all three works with modern laptops and MacBooks without an adapter
  • Real stated transfer speeds (Picks 2 and 3) give a genuine performance data point rather than vague marketing language
Cons
  • None of the three are the cheapest 1TB-labelled listings you’ll find — that’s specifically because they’re genuine branded capacity, not fake
  • 1TB may not be enough for very large backup needs — check whether a 2TB genuine branded option fits your budget if so
  • As with any storage purchase, backups should still exist in more than one location or format, not solely on a single portable drive
Before you buy

What to Check Before Buying Any Portable SSD

What to look for

What to Check Before You Buy

01
Established, verifiable brand
Capacity fraud is essentially unheard of from major, established storage brands.
Look for
A named brand with a public track record, like SanDisk, Crucial, Samsung, or Western Digital.
Avoid
Unbranded or generic-sounding storage listings, especially at unusually low prices for the claimed capacity.
02
Price relative to known market rate
Genuine 1TB portable SSDs have a fairly consistent real-world price range.
Look for
Pricing broadly in line with other verified branded 1TB listings.
Avoid
A capacity claim priced dramatically below the norm with no stated reason (clearance, warranty exclusion).
03
Stated transfer speed
A specific speed figure suggests a real tested product rather than vague marketing.
Look for
A specific MB/s figure stated in the listing.
Avoid
No performance information at all on a listing marketed for backup speed.
Frequently Asked Questions

Portable SSDs for Backups: Frequently Asked Questions

How can I tell if a portable SSD listing is a capacity scam?

Compare the price against the known market rate for genuine branded storage of that capacity. A dramatically lower price for a high claimed capacity from an unbranded seller is the clearest warning sign.

What happens if I buy a fake-capacity drive?

The drive’s firmware reports an inflated capacity, and data written beyond its real, smaller size gets silently corrupted, which is especially dangerous for backups you’re relying on.

How do I check a drive's real capacity after buying it?

Free capacity-testing tools exist that write and verify data across the drive’s full claimed size, exposing a fake capacity quickly rather than risking corrupted backups later.

Is 1TB enough for backup purposes?

For most personal backup needs, yes. If you have very large media libraries or backup needs, check for a genuine branded 2TB option rather than an unusually cheap high-capacity unbranded listing.

Which brands are considered reliable for portable SSDs?

SanDisk, Crucial, Samsung, and Western Digital are among the established, verifiable brands with long track records in portable storage.

Should I rely on a single portable SSD as my only backup?

No, it’s good practice to keep backups in more than one location or format rather than relying solely on one drive, regardless of how reliable it is.

Does USB-C 3.2 Gen2 make a real difference for backups?

It offers faster stated transfer speeds than a standard USB-C connection, which meaningfully reduces time for large backup transfers specifically.

What should I check before buying any portable SSD for backups?

The brand’s legitimacy, the price relative to known market rates for that capacity, and whether a specific transfer speed is stated.

Key Takeaways

Key Takeaways

  • A suspiciously cheap high-capacity drive is a red flag, not a bargain. Genuine 1TB portable SSDs from established brands cost roughly £90-135 in the UK.
  • Capacity fraud is a real, documented pattern. It specifically targets unbranded, generic-sounding storage listings at unusually low prices.
  • Established brands essentially eliminate this risk. SanDisk, Crucial, and similar brands have public track records worth paying for.
  • Verify capacity with a free testing tool if unsure. Especially important before trusting a drive with actual backup data.
  • Keep backups in more than one place. Even a trustworthy branded drive shouldn’t be your only copy of important data.
