if your on a budget then go for the cheaper non pro,i have both drives and can't tell any difference between them,its only in benchmarking software you would see any difference
im speaking for the 256/250gb models,smaller size models might be different as its the size of the drive aswell that affects speeds,the bigger the better
Thanks guys. I went with the non pro version. Only needed 120g too as not storing anything on the laptop.
(Sorry OcUK bought elsewhere. Your prices need looking at!)
Do you need an adaptor to install these into laptops?
