A great value for a boot drive. The only thing that holds it back is the lack of a DRAM cache, but for the price, it is an excellent choice. I know many people who use this drive; for all of them, it has not caused a single problem.

A pretty decent SSD for a faster boot drive on a budget.


Good

With SATA-3 cables/controller/motherboard and in AHCI or Intel RST mode works just nice! Weight is really light and the case is fully aluminium. Yeah, memory type of this SSD is MLC, but still performs very well.


Average

Quite slow speeds compared to it's other slightly more expensive competition. I can't recommend it. You get what you pay for I suppose.
