The write speed has deteriorated a lot in just an year. The seq write speed decresed from 300MB/s to only 50MB/s.

Very slow SSD wish I never bought it


Terrible

poor life time...30 days drop to 97%


Terrible

It's cheap, the performance and capacity is cheap.


Average

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


Poor

4 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

11 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

12 months ago.

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


Average

24 months 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

21 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
