The "best external hard drive" lists are mostly affiliate bait. They rank by commission, not by whether the drive will still work in 5 years.
Here is a clear method you can follow in about 5 minutes.
Step 1 — Don't use an SSD for backups
SSDs lose data if left unplugged for years (electrons leak). If you are backing up files and putting the drive in a drawer, you need a spinning HDD.
Only use an SSD for active, daily work.
Step 2 — Look at the Brand
Hard drives are mechanical. The two most reliable manufacturers are Western Digital (WD) and Seagate. Avoid "no-name" brands on Amazon.
Look for the WD My Passport or Seagate One Touch.
Step 3 — Check these 3 specs
Before you buy, look for these three things:
- USB 3.0 or USB-C: For fast transfers.
- At least 2TB: 1TB fills up fast.
- Hardware encryption (optional): If you are carrying sensitive data.
If a listing has a known brand, USB 3.0+, and at least 2TB, it is worth looking at.
Step 4 — Run the find
Instead of reading 20 reviews, tell the find engine exactly what you need. Use this query:
❯ external hard drive 2TB, WD or Seagate, USB 3.0, UK
Rallynex will:
- Search live listings across retailers.
- Filter out the no-name brands.
- Cross-check the specs against known reliable models.
- Show you the ones that actually deliver — with the source, the price, and the specs.
The short version
- Do not use an SSD for long-term backups. Use an HDD.
- Stick to WD or Seagate.
- USB 3.0 is fast enough for backups.
- 2TB is the sweet spot for price and capacity.
That is the whole method. Everything else is marketing.
