A couple of days ago DailyTech reported that there were problems with Samsung's 32nm NAND flash memory. The site contacted
Samsung and heard the new 32nm flash will need a new SSD controller to work properly. The South Korean giant is working on a revision of its flash controller, and its probably safe to assume Indilinx is updating its Barefoot SSD controller as well.
DailyTech reported several days ago that SSD manufacturers have been having problems with Samsung's latest generation of 32nm NAND flash. The new chips have slow write speeds, thus making them unsuitable for use in SSDs since that is one of the major advantages that the new drives have over conventional hard drives.
We have received a reply from Samsung confirming the issue, stating that "for quality SSDs, every NAND process geometry upgrade requires a matching upgraded controller. Should (Samsung's) 30nm-class NAND be used with a conventional controller of insufficient quality, performance slowdowns are indeed possible".
