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 haven’t
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.
