Seagate ST500LM000 500 GB

A 500GB 2.5" HDD on the SATA interface. At roughly $0.09 per gigabyte it sits in the budget tier. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 64MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $44.99 price tag places it squarely in budget territory. PlanMyPC's builder flags compatibility problems automatically and adds the part's price to your build total.
