As a business device it touts several security features, such as encryption. Hitachi is offering an optional self-encryption technology which will protect sensitive company data, as well as enhance secure erasure of information. Since encryption is handled by the drive itself and not software on a computer, this could save time, effort and money.
 
The SSDs comply with the the Trusted Computing Group's Enterprise A Security Subsystem Class encryption specification.
 
Hitachi has worked with Intel to develop the high-endurance SLC NAND flash memory and has produced the SSD400S.B in three capacities: 100GB, 200GB, and 400GB. It features a 2.5-inch 6GB/s Serial Attached SCSI interface, which opens up potential avenues for use as tiered storage in datacentres.

The SSD has up to 536MB/s and 502MB/s read and write speeds respectively. IOPS speeds are also up to 57,500 and 25,000 for reading and sustained writing, making the device 100 times faster than traditional hard drives.
 
Reliability is also one of the primary selling points, with the 400GB version able to endure up to 35 petabytes of random writes before finally petering out. To put that in context, that would mean five years of writing close to 20TB every single day, which is far more than people are likely to use, and given the relatively low capacity of SSDs in comparison to HDDs it would mean overwriting data several times a day. Additional advanced data integrity and power loss management technologies enhance the device's reliability.
 
The SSD400S.B is available immediately through select original equipment manufacturers. Self-encryption does not come as standard, and all versions of the device come with a five year or max petabyte write limited warranty.
