OWC Mercury Electra 6G 1 TB

This is a 1000GB 2.5" SSD on the SATA interface. At roughly $0.12 per gigabyte it sits in the high-end tier. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.

Its $116.75 price tag places it squarely in high-end territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.
