OCZ has finally made available their Z-Drive series of SSDs, which overcome the throughput issues of serial ATA by skipping it altogether and using the PCI Express bus. While they are expensive, they do offer a new class of performance over even the fastest SSDs on the market today.

The new Z-Drives (no, ‘Z’ does not always have to mean zombie) read speeds of 450 – 510MB/s and write speeds of 300 – 480MB/s depending on the model. Unfortunately, that speed comes at a very literal cost: the cheapest of the drives, offering 250GB of capacity, runs a staggering $1560. The highest end offering, giving up 1TB of high-speed flash storage, will run more than twice that at close to $3400. The Z-Drives are essentially the same flash chips found in the company’s pre-existing SSDs, integrated with a hardware RAID controller and cut to fit a PCI-e x4 form factor. Currently, the drives are only available at Amazon.com.
