WD and SanDisk unveil new SSDs: starting at $100 for 250GB, built on 64-layer 3D NAND

Western Digital and its subsidiary SanDisk revealed new SSDs using 64-layer 3D NAND memory. They start at an affordable $100 for the 250GB model and going all the way up to 2TB. They are nearly identical, except that the WD drives come in 2.5/7mm and m.2 2280 form factors, while the SanDisk is available only in 2.5 flavor.

Both SSD models are based on a Marvell controller and the higher capacities should offer 560MB/s sequential read, 550MB/s sequential write, also 95K/84K IOPS in random read/write. The base 250GB model is a bit slower, though not by much.

The drives are available in 250GB, 500GB, 1TB and 2TB capacities and will be available in the third quarter of this year, starting at $100 for the 250GB model. Prices for the higher capacities havent been announced yet. The previous generation Blue SSD offered 1TB for $300. Anyway, the new drives all have a 3-year warranty and are rated at 1.75 million hours MTBF.
