Super fast speed for a smaller 120 drive. Compares to 850 Pro speeds for about $100 less! Found it on sale for $69.99 and is the best bang for the buck!

Excellent product, very good performance!!!

Really good price to performance on this MLC SSD. for a 120GB it delivers a punch as most 120GB models have limited performance, as producers want you to buy the larger capacity, more expensive models such as 240GB and so on. This drive competes with other top quality, low price storage drives. —Nov '17

It's tiny as $hit but o-boy if it's faster than a HDD. And also, for some reason, is cheap as hell :D
