Western Digital Scorpio Blue 80 GB

This is a 80GB 2.5" HDD on the SATA interface. At roughly $0.61 per gigabyte it sits in the budget tier. Sequential throughput tops out at 550 MB/s reads and 520 MB/s writes, backed by 8MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $49.00 price tag places it squarely in budget territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.
