It's a Mushkin Chronos, which was very well reviewed.
What happened last night was I used Super Duper to copy my original HDD's contents to the SSD, swapped drives and rebooted. Boot time was impressive, as was FFX loading. I had a 15 minute YouTube clip playing while I did the dishes. It ground to a halt in the middle of the video, and my pointer was stuck on beachball. I let it sit for about 10 minutes, but it did not recover. I then held down the power button to force a shutdown. When I powered the laptop back on, it flashed the "no disk" icon.
I have an Thermaltake BlacX, and when I plug the SSD into it this afternoon, Disk Utility doesn't show any drives connected other than my lappy's internal HDD and optical drive.
