OCZ Vertex beta firmware with background 'Garbage Collection'
 

OCZ wanted some feedback from us on their previously hush-hush project: custom Indilinx firmware. Since they did not have the end-user flasher ready to roll, they passed us a sample that was pre-flashed from their lab. The internal firmware revision was 1585. It arrived a couple of days ago, and I've been beating on it ever since.
