Western Digital Scorpio Black 500 GB

A 500GB 2.5" HDD on the SATA interface. At roughly $0.5 per gigabyte it sits in the high-end tier. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes, backed by 16MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.
