OCZ first unveiled its Z-Drive at CeBit earlier this year with a few scant details but today we can fill in a lot of the information gaps as OCZ officially announced the immediate availability of the Z-Drive line of PCI-Express solid state drives. The drives incorporate a built-in RAID controller and a four-way RAID 0 configuration with x8 PCI-E lanes to offer some pretty impressive performance numbers.
The Z-Drive is available in multi-level cell (MLC) and single-level cell (SLC) models, referred to consecutively as p84 and e84, with three different capacities being offered - 256GB, 512GB, and 1TB (p84 only). OCZ has published conflicting numbers concerning maximum read/write speeds when you look at the product announcement versus the numbers published on its web site, so we'll go with the more conservative numbers. The maximum read/write speeds for the MLC-based p84 models are 750 MB/s and 650 MB/s respectively. As you would expect, the e84, based on the SLC NAND flash memory can offer higher throughput with maximum read speeds of 800 MB/s and maximum write speeds of 750 MB/s.
While OCZ didn't share pricing information with us, a check online showed one site offering the 1TB p84 MLC drive for $3,200US.
