This product is very good. It is very fast. Loads from the Power button to windows in +-2 seconds. Its not the newest gen or the fastest, but to be honest in the real world you will not notice a difference. I will recommend this product to anyone.

Brilliant upgrade for a boot drive if you motherboard supports it. Excellent boot time speed - I'm on the login screen within literally 5 seconds.
I've been using the Adata XPG SX8200 256GB M.2 drive and the Corsair really improves on boot up speed so I'm extremely impressed and I'd highly recommend this drive.

These are some of the faster m.2 ssd's available in this performance segment. The price outshines the western dig black, and samsungs by a significant margin, but the performance is still within the same ballpark as the other brands. Highly recommended!
