Silicon Power S55 480 GB

This is a 480GB 2.5" SSD on the SATA interface. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes. At roughly $0.22 per gigabyte it sits in the mid-range tier. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work.
