Very Very Fast
Pros: Lightning Fast. Caught on $40 off sale!!! Thanks, Newegg!
Cons: Actual read/write times may vary from datasheet, but does not interfere with the fact that a ssd will beat the heck out of any hdd.
The screws for mounting the adapter plate may not work in all cases (Antec 900). I used velcro to mount the plate.
Other Thoughts: Version 1.5 of the firmware was released on July 2, 2012. It is unlikely that a drive has shipped with the latest firmware. In fact, TOOLBOX will not offer to run firmware if the drive is up to date. Follow the instructions, and your drive will work faster than ever. When they instruct you to shutdown and run again, do not just reboot. You must power down and turn back on. (trial and error proof)
