Western Digital Blue Mobile 2 TB

This is a 2000GB 2.5" HDD on the SATA interface. At roughly $0.1 per gigabyte it sits in the high-end tier. Sequential throughput tops out at 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.

Expect to pay around $198.00, which lands it among high-end options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.
