WD Blue 2.5-inch HDD Spec and Price in the United Kingdom
The 2.5-inch Blue is WD's laptop and SFF hard drive: 5400rpm, a 128MB cache, and the 7mm height that fits standard 2.5-inch bays in notebooks and external enclosures alike, per the WD product brief. Sequential throughput is 150 MB/s — the ceiling the SATA III interface would permit only if the platters were faster, which 2.5-inch mechanics are not. The two-year warranty matches the 3.5-inch Blue.
Prices include VAT.

What owners and reviewers say
Summarised from 1 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- One of the first thin 2.5-inch drives to reach 1TB, with top-of-class performance in that category.
- Bundles shock, vibration and head-parking protections, with low power draw suited to mobile use.
Commonly criticised
- Lagged a slightly thicker same-capacity sibling in several workloads.
- Some results were only mid-pack, and measured power use was a little above the vendor's claims.
