How Real-World Numbers Make the Case for SSDs in the Data Center REGISTER >

New Ultrastar drives, which use Intel's 25-nanometer high-endurance NAND flash, are designed to serve as a Tier 0 layer for high-transaction-type applications.

SANTA CLARA, Calif. -- Hitachi's global storage division, needing to find a way to keep up with the constant advances in NAND flash at competitors such as Toshiba, Samsung, Micron, SanDisk and Seagate, on Aug. 9 introduced a new line of MLC (multi-level cell) solid-state disks for enterprise systems.

The announcement was made at the annual Flash Memory Summit here at the Santa Clara Convention Center, which continues through Aug. 11.

Hitachi's new Ultrastar SSD400M drives, which use Intel's 25-nanometer high-endurance NAND flash, come in a 2.5-inch form factor with a 6Gb SAS interface in capacities of 200GB and 400GB. It is designed to serve as a so-called Tier 0 layer for high-transaction-type applications.

Tier 1 storage, also known as production storage, usually consists of high-speed SAS (serial-attached SCSI) hard drives and is considered the primary tier for production data. Tier 2 and Tier 3 storage tiers (generally consisting of slower, cheaper SATA -- or serial ATA -- drives) handle non-critical data that does not require the speed of Tier 1 storage. Some archiving is done at the Tier 3 level.

Tier 0 is SSD-based storage used to improve performance beyond what current Tier 1 storage can offer for selected applications, such as financial services, retail sales, and others. Early on, Tier 0 storage has consisted of a RAM disk, which is more expensive than NAND flash. NAND flash is moving quickly into this space.

Ultrastar SSD400M 400GB features write endurance of 7.3 petabytes (PB) lifetime random writes, Hitachi said, which equates to 10 full drive writes per day for five years. The new multi-level SSDs also include all of the enterprise features found in the company's front-line Ultrastar single-level cell (SLC) drives, such as end-to-end data protection, error correction and error handling, Hitachi said.

"Tier 0 enterprise applications are of increasing importance as more and more IT managers are redesigning their data centers for improved total cost of ownership, and to support advances in cloud computing, virtualization and thin provisioning," said Joseph Unsworth, research director of NAND Flash and SSD at Gartner.
