SanDiskExtreme SSD - SDSSDX-480G upgrade

I have a W520 and need to upgrade my drive.

What device shoudl i go with?

Hello,

as far as i can understand your question you want to upgrae your laptop/netbook with an extreme SSD. in that case the only thing you have to make sure is if the laptop/notebook has a normal SATA connection or a mSATA connection with the existing drive.

if you have the SATA connection you can use any retail drive from Sandisk. if you have a mSATA connection you must contact your manufacturer of your pc to ensure that you will buy a compatible drive.
