Western Digital Green 120 GB

This is a 120GB 2.5" SSD on the SATA interface. Sequential throughput tops out at 550 MB/s reads and 520 MB/s writes. At roughly $0.29 per gigabyte it sits in the budget tier. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $34.99 price tag places it squarely in budget territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.
