Both drives also incorporate Toshiba’s proprietary QSBC (Quadruple Swing-By Code) error correction technology. QSBC is a highly efficient error correction code (ECC) that helps prevent corrupted data caused by NAND wear, improving reliability and extending the lifespan of the drive.

    Is it possible tha these controllers are based on OCZ IP ?
    i mean, it would make sense, since they bought them and OCZ has lots of expertise in controller tech.

      Or possibly Phison, as there is a relationship there also, and Phison has announced plans to move more strongly into enterprise controllers.

      • blank

        Yeah, but they dont own Phison though, so it makes little sense to license controller IP if you have one inhouse.

        But does Toshiba’s inhouse have an enterprise version? Until they develop their own, they may have to go outside so as to get a foothold in an exploding market now. Keep in mind that the press release says “Toshiba-designed”, not “Toshiba-produced” or “Toshiba-designed and -produced.”

        OCZ has bunch of enterprise grade stuff and plenty of expertise in that field, so its only reasonable to get that from them (since they own them).
