Is a beast
Normally I do not write reviews, but this ssd is a beast. I have XPS 9710 I clone drive C to the new SSD 4TB and the performance such as copying pasting photoshop open folders are very fast and noticeable.

Lightning Fast🔥🔥🔥
It's really a beast, I' am using this is my victus gaming laptop. I love this, I am playing GTA V, Horizon forza etc heavy end games without any lag. I know this performance is also depend on other components. But this nvme is doing maximum from the storage disk side. 7300 Mb/s read speed as per they advertised. Really recommended.
