The low prices and high speed access of the Sandforce controller made it an appealing option for SSD manufacturers such as Toshiba, Intel, Kingston & OCX. But it soon became a problem for users when the SSD devices using these controllers started to fail in their computers after just six months of use. Usually it resulted in the device not being recognised by the computer bios, and not functioning at all.
That was okay if you were happy to have it replaced under warranty by the manufacturer. The problem came when you wished to try and recover critical data that may have been stored on these SSD’s. The use of full hardware encryption on the controller and the device, meant that the data could not be recovered, even when using low level data chip removal.
Fortunately today these controllers are not so popular, and as a result most mainstream manufacturers do not use them. But be aware that they can still be found in some non branded SSD’s.
