That model appears to already have a 160Gb SSD. Were you wanting to replace the current SSD or replace the 500GB HDD? The only question is whether your computer supports SATA III. If it doesn't, then you won't get the full speed from that SSD. I can't tell whether your computer uses SATA II or SATA III.
Did you get your SSD? How do you like It? Mine is awesome and just wanted to see what you think of yours.
