Seagate BarraCuda 3.5-inch HDD Spec and Price in the United Kingdom
BarraCuda is Seagate's mainstream 3.5-inch line: the 1TB and 2TB SKUs spin at 7200rpm while the 4-8TB capacities run 5400rpm, all with 256MB of cache at the larger sizes, per the Seagate data sheet. It is CMR across the current lineup, which is what separates it from BarraCuda's discontinued SMR generations and the WD Blue at the same shelves. The two-year warranty and the price-per-terabyte make it the default bulk-storage drive for desktop builds.
Prices include VAT.

Commonly criticised
