OCZ releases next-gen PCIe SSD

From InfoWorld: OCZ today released the fifth generation of its PCI-Express SSD (solid state drive), which it said can perform at a 2.8GB/sec read rate.

The new Z-Series SSD R4 doubles the performance of the previous generation SSD, according to OCZ CEO Ryan Petersen.

Past generations of OCZ's Z-Drives sported up to 2TB of capacity and 1.4Gbit/sec throughput. The latest model comes in capacities ranging from 300GB to 1.2TB on a half-height card and from 800GB to 3.2TB on a full-height card.

Unlike previous generations of OCZ drives, which were sold directly to end users, the new hardware is targeted directly at server manufacturers.

One major systems manufacturer expects to ship a card with four OCZ PCIe controllers, generating over 400,000 4K random input-output operations per second (IOPS), Petersen said.

The new generation of OCZ SSD drives use Micron's NAND flash with 25 nanometer circuitry .

Micron also makes a competitive line of PCIe-based SSDs for enterprises.

The Micron P320h line , announced in June, boasts performance of up to 3GB/sec. However, Micron's card uses high-end SLC (single-level cell) NAND flash. OCZ's SSD uses less expensive MLC (multi-level cell) flash, which allows it to offer its product at $7 per gigabyte.
