SSD Specs Database

Maintained by Gabriel Ferraz:
"I'm a computer engineer from Brazil, with a passion for hardware, who started this project to catalog all SSDs out there. Special help was provided by my friend Riccardo Buonaurio. He helped me a lot in finding some information."

Below you will find a reference list of most solid-state-drives released in recent years.
