I've always wondered about how data recovery works with solid state drives. At Storage Visions 2012 we spoke with Drive Savers and found out exactly how the process unfolds and also learned about pricing for most cases.
I'll tell you that the cost is a bit prohibitive, it's pretty common to see bills getting into 2K USD but as you know, some data simply does not have a price.
In the pictures you see some drives that have gone through the recovery process for various reasons. If you look closely a few of the drives have been dismantled with the flash removed from the PCB. While rare, in some cases the flash has to be read individually and the data reconstructed from fragments.
