Intel worked with SandForce for  a year and a half to produce an SSD that met Intel’s rigorous standards, and made hundreds of changes to SandForce’s firmware.  Users of SandForce controllers can differentiate their SSDs through the addition of features in the SSD controller’s firmware.  Intel did this by tapping into its expertise in end-to-end data protection (something the company learned when working with Hitachi to introduce that company’s Intel-based enterprise SSDs) while harnessing Intel’s deep understanding of its own NAND flash and of the I/O needs of the PC.

End-to-end data protection is not a trivial feature: Continue reading
