Yes, this entire problem of new SSDs always falling into severely poor performance ruts, with the firmware fix then "bricking" drives, and the second firmware update required to resolve the problem. Intel had this problem twice, now Crucial.
The original firmware has a slight chance of bricking the drive, but generally should be okay to use... the firmware fix had a better chance of bricking drives during the update process, and then it was discovered their software program itself had an issue with certain motherboard configurations.
They stated they would begin tested of a final solution on May 10th with the update to go live this month if no more issues popped up.
So far the only new controller to not have a performance/reliability snafu has been Sandforce. Intel, Indilinx, and Micron have each endured theirs (Not counting JMicron)... so I'm wondering if something's going to crop up with Sandforce given it has with everyone else. Jumping to bleeding edge technology does have its risks, especially for the first SSD to incorporate the C300's controller and the first SSD to use SATA 3.
