I bought this ssd because, having bought a "B650M AORUS ELITE AX ICE" motherboard, I wanted to put a maximum capacity ssd on it: a M.2 PCI-E 5.0 4x ssd.
The product is a bit expensive compared to others for the same capacity; but from what is offered at LDLC, all the PCI-E 5.0 4x are in the same price range.
From what I've been able to test, the transfer speed is more than adequate. I'd recommend this product to anyone looking for a high-performance ssd.
