Corsair shared more info its plans for the upcoming transition from 34nm to 25nm NAND flash memory on its solid state disks.

The 25nm NAND flash memory is cheaper to manufacture but the downside is that it's less durable and somewhat slower than the previous generation. The company says more over-provisioning will be needed to ensure reliability, and reports tests show a roughly 3-4 percent drop in performance. All of Corsair's new Force SSDs with 25nm NAND will get an "-A" suffix to make it easy to determine the difference with the 34nm disks.

Corsair, a worldwide designer and supplier of high-performance components to the PC gaming hardware market, today announced its plans for the upcoming transition from 34 nanometer to 25 nanometer flash chips used on its solid-state drives.
