Summary: Purchased two of them four years ago (for roughly the same price as they are sold today). Worked great for four years, although I would get occasional "Blue Screen of Death", which seemed to be related to those drives. Used in a Raid0 configuration as my boot drive, the performance was outstanding.
Summary: Gave me 5 good years and then crapped the bed yesterday. Controller apparently died as it no longer shows upas a drive with any interface . Sort of painful since it was the OS. The 1T drive sitting next to it is still kicking along and it got most of the work.
Great performance, flashing firmware is a NIGHTMARE

Summary: This drive provides great performance, when it works properly! I have had numerous issues with these drives in several PC's I have either upgraded to use this drive, or built from scratch with this SSD as the boot drive.
Summary: My company bought me this solid state model (S599) with 256GB. It has been just over a year and the drive died on me. Worked fine, shutdown my laptop before lunch, came back and nothing. Tried using an external enclosure to access the drive on another machine and nothing. Drive is complete screwed.
Summary: I got this drive for a laptop, created a factory image on it, and had a great time using it for about 3 weeks. Unfortunately, at the end of 3 weeks, it simply died. No error messages, no nothing - just will not be recognized by the bios anymore.
Summary: I bought two of these and put it on my GA-X58A-UD3R v2.0, set it up on RAID0 and the speed is incredibly fast. My OS is Win7 x64. Very easy to set up. I got a 7.8 mark on the windows benchmark on the hdd item.
Summary: If this unit works for you good, but beware if you need to get any service from ADATA. They are extremely slow and their process is inadequate. Here's my story: I bought this unit to install in my Dell Laptop.
