This week, OCZ Technology Group Inc. unveiled the Z-Drive, a PCI-Express (PCIe) solid-state disk (SSD) drive designed for enterprise-class data centers that boasts throughput speeds of up to 800MB/sec.

OCZ said the new drive is bootable and takes the serial-ATA (SATA) bottleneck out of the I/O equation by employing a high-speed PCIe architecture coupled with a compact enterprise-grade RAID array. The drive has 8 PCIe lanes and an internal four-way RAID 0 configuration to increase performance.

The PCEe interface is currently rated at 500 MB/sec per lane (8Gbit/sec with 8 lanes). PCIe 3.0, to be released in 2010, will have a throughput rate of 1GB/sec per lane. SATA's maximum throughput is currently at 3Gbit/sec., although it is moving to 6Gbit/sec.

OCZ offers customization options for OEM clients that want tailored hardware or firmware options for their businesses.

"The Z-Drive is designed not only to be higher performing and more reliable than conventional solutions, but also to significantly reduce both the maintenance and overall TCO for our clients," Ryan Petersen, CEO of the OCZ Technology Group, said in a statement.

The drive is available in multi-level cell (MLC) NAND flash memory and single-level cell (SLC) models referred to as p84 and e84 respectively. According to OCZ, the p84 Z-Drive has a maximum sequential read rate of 750MB/sec and a maximum write rate of 650MB/sec. Using a 4KB file size, the drive has a maximum rate of 10,000 input/output per second. The e84 Z-Drive, on the other hand, has a maximum sequential read rate of 800MB/sec and a maximum write rate of 750MB/sec. This SLC model can achieve up to 16,000 input/output operations per second.

Available in 256GB, 512GB, and 1TB (p84 only) capacities, the Z-Drive comes with a three-year warranty with technical support.

OCZ did not offer pricing for the drive, which is normally dictated by its resellers.
