Western Digital Scorpio Blue 500 GB

This is a 500GB 2.5" HDD on the SATA interface. At roughly $0.26 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 8MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $129.99 price tag places it squarely in high-end territory. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing.
