What HDD is in the laptop now?
As to 4 and 8mg, that would be milligrams? Must be a typo. Check Crucial.com for memory. Crucual might make an offer on their SSD's as well.
Help would be appreciated with this upgrade as info on my old Sony VGN-FW378D is scarce and the question is the ScanDisk ExtremePro SSD compatable on the data transfer rate capacity or other unknown challenges with this upgrade? OS is Vista and I want to upgrade to Windows 7,,it has 4mg memory w/8mg max capacity. The old dog works fine but needs some boost. Any info would be great. Thank you.
