Excellent SSD at a good price. I had to buy a copy of Windows 10 to use it as a system drive but that was my bad (lack of research), glad I did though, I don. know why I clung on to Windows 7 so long now. Plenty of emails from CCL keeping me informed until it was delivered, which wasn't very long. I've read a few bad things people have said about CCL but I've purchased from them quite a few times and there has only been the odd minor hiccup.
