It's not bad,but doesn't have TRIM support...


Average

It is perfect for a laptop drive, not so much for a gaming PC. The low capacity on this drive also makes it a very poor game drive. On the flip side, boot times are 2-3x as fast as a traditional hard drive.

The most basic SSD par excellence, useful to improve performance with little money expenditure.


Average

2 years ago.

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

2 years 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
