Western Digital Blue Mobile 1 TB

A 1000GB 2.5" HDD on the SATA interface. At roughly $0.1 per gigabyte it sits in the mid-range tier. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 128MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

At $99.99 it sits in the mid-range drive bracket. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current drive prices across retailers.
