Mum's the word on what controller Hitachi has attached to its new enterprise-class Ultrastar SSD400S.B family of solid state and whether it skipped Intel's chipset in favor of something from SandForce, just like the Santa Clara chip maker recently did, but we at least know the new SSDs are rocking Intel-produced 25nm single-level cell (SLC) NAND flash memory chips, a fact both companies are quick to boast.
The new Ultrastar SSD400S.B family is the first in the business to use 25nm SLC NAND flash chips, a more expensive solution to multi-level cell (MLC) chips, but also more reliable, which is why they're preferred in mission critical environments.
Hitachi's new SSDs are shipping in 100GB, 200GB, and 400GB flavors and feature 2.5-inch 6Gbps Serial Attached SCSI (SAS) interfaces. They've been rated to race along at up to 536MB/s for sequential reads and up to 502MB/s for sequential writes, along with up to 57,000 read and up to 25,500 sustained write IOPS.
Pricing has not been announced, but considering these are enterprise drives with SLC memory, they won't be cheap.
