OCZ Agility 3 SSD, 120GB, SATA 6Gb/s, model AGT3-25SAT3-120G http://www.amazon.com/dp/B004Z0S6SO/?tag=tec06d-20 $84.99 with free shipping ($69.99 after $15 mail-in rebate) Notes Some people have reported that their motherboard won't recognize this drive. Be sure to test for this soon after delivery, in case you need to send it back. The latest firmware is version 2.22 (you can use a utility like CrystalDiskInfo to report on the installed firmware). OCZ says that you can't update the firmware if the SSD is your Windows boot drive. If you need to update the firmware, be sure to do it before you install the o.s. Many computer cases don't have a 2.5" drive mount. You can get a 2.5" to 3.5" drive bay adapter or take the cheap route and use double-sided sticky tape. Amazon sells the Silverstone SDP08 3.5" to 2 X 2.5" bay converter for $12.99.
