NAND flash.

The company’s new SSDs for its Ultrastar enterprise drive lineup – officially, the Ultrastar SSD400S.B, which comes in 100 GB, 200 GB and 400 GB capacities – are equipped with 6 Gigabit per second SAS interfaces in a 2.5-inch form factor. Hitachi says that it uses proprietary “endurance firmware” which allows the drives to survive heavy usage, and claims its 400 GB SSD can handle up to 35 petabytes of random writes over the drive’s lifetime.

Hitachi says the drive’s interface allows up to 57,500 reads and 25,500 sustained writes inputs/outputs per second. The company also offers a self-encrypting drive option that scrambles and descrambles data as it is stored and accessed, according to Hitachi. The hardware-based encryption relies on an encryption key to work, so the company claims that deleting that key will make data inaccessible on its self-encrypting drives.
