Very slow SSD wish I never bought it

120GB is low count limited, but Pretty fine for basic FHD, high textures loadout gaming :)

My bios never recognised that disk even though it worked with the Samsung 840 Evo and 850 Evo. Bad choise.

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

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


3 years ago.

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


2 years 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.


2 years ago.

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


3 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.


3 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


13 months ago.

its a low end one, pay for what ya get and you really dont get much
