Hitachi recently released a new enterprise class SSD based on Intel’s 25nm MLC flash. Dubbed the Hitachi SSD400M, the new solid state drive is aimed at Enterprise users and Cloud data centers. It comes in the standard 2.5" form factor, features a SAS 6Gb/s interface, and will be available in 200GB and 400GB capacities.
As an enterprise drive, the Hitachi SSD400M supports end to end data protection, error correction, error handling and self encryption on certain models compliant with the Trusted Computing Group’s Enterprise A Security Subsystem Class encryption specification. Further showing it’s intended usage as an Enterprise drive, the 25nm MLC based drive is rated for 7.3 Petabyte lifetime write, which Hitachi says amounts to 10 full drive writes per day for five years. Coincidentally, the warranty of the drive is a five year limited warranty or until the drive exceeds the maximum rated number of petabyte writes per capacity. Hitachi states that they expect a .44 annual failure rate and have projected a 2 million hour MTBF.
Performance of the drive is much better than that of the previously reported Intel drive, as it delivers 495MB/s sequential reads and 385MB/s sequential writes. The SSD is further rated at 56,000 read IOPS and 24,000 write IOPS.
The SSD400M has already shipped to various OEMs and will be available soon. More information on the new SSD can be found here.
