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


Poor

5 months ago.

Offers poor performance over other SSDs at around the same price point with low read and write speeds and very small capacity.


Average

12 months ago.

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.


Good

13 months ago.

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

23 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
