Intel's 335 Series has nearly identical specs to the 330 Series, but ships (as of now) only in 240GB capacity size and uses 20nm synchronous NAND flash. Intel rates the new 20nm flash at 3K P/E cycle just like the 25nm flash used on the 330. Even though the 330 and 335 share almost identical spec sheets, we expect some improvement in other areas. Intel had an extra year to work on the 335 Series firmware. Firmware and programming are just as important as the hardware used to make an SSD. We also want to keep an eye on latency since latency should increase as the lithography shrinks. The LSI SandForce SF-2281 is the perfect controller to look for increased latency since it lacks a DRAM buffer.
