Comment Re:Different failure mode (Score 2) 82
My experience is quite different to this - most SSDs I've seen fail have been the flash that's failed, and the drive puts itself into read-only mode so that it won't damage the flash with further writes. This allows you to copy the data off the drive. Interestingly, some failed SSDs report to the OS that they are read-only, but others pretend to be a read/write device, but they silently discard all the writes. At least you can still get the data back that has already been written though.
If however the controller fails, then the drive can suddenly die - and as most drives are using some form of encryption on their flash chips, even if you transplant another controller, the crypto keys will not match and the data will be unrecoverable.
