If you take a look at the spec sheet under 'Storage' you'll see your system only has a SATA II (3.0 Gb/s) interface so the SSD you get needs to be able to run at this speed. Review the SSD's spec sheet to double check. As an example here is a drive that will work: [http://www.samsung.com/semiconductor/minisite/ssd/downloads/document/Samsung_SSD_750_EVO_Data_Sheet_Rev_2_1.pdf|Samsung 750 EVO] Note the 'Interface' line clearly states it runs in all three SATA specs. this drive has auto I/O speed sense technology, many drives today don't as the market for upgrading older SATA I & SATA II systems is waning and to be price competitive the drive companies (both HD & SSD) are dropping this ability and only offering fixed SATA III drives.
