Its okay for a budget SSD and for just storing the OS and nothing else on it, but you may as well spend slightly more money for more space and faster speeds.


Terrible

3 months ago.

Horrible SSD, uses a controller with a known reputation for failing, and is more expensive than significantly better SSDs, like the WD Green, SU650, and L5 Lite 3D
