Just How Fast is OCZ's New 1 TB SSD?

It's been barely a day since we first brought you the news of OCZ's massive 1 TB solid-state drive.  In case you missed it, here's a quick rundown: Dubbed the Z Drive, this powerful, videocard-like device hooks into your PCI Express x8 slot to deliver the punishing performance of a RAID 0 array of four, 256 GB solid-state drives.  But that's not all.

The Z Drive also sports a hardware RAID controller and 256 MB of onboard cache. This helps the device allegedly achieve read and write speeds of 600 MB/sec. and 500 MB/sec. respectively.  Or, at least, that's what OCZ's been boasting about its new $1,500 device.  Belgian Web site Madshrimps was able to get its hands on a Z Drive for a little bit of benchmarking action and here's what they were able to find.

Next, the benchmarks: Madshrimps fired up HD Tune Pro 3.10 and was able to coax the Z Drive into delivering 100 MB/se.c read and write speeds when using smaller file lengths of around 4K for the testing.  As they increased the file lengths on the benchmark, the Z Drive's transfer rates shot up to appoximately 1,400 MB/sec. read and 1,100 MB/sec .writes.  That's a crazy amount for a synthetic benchmark, but what about performance results that are more indicative of real-world use?

Madshrimps fired up SiSoft Sandra File system and found that the Z Drive outputted a drive index of around 550 MB/sec.  This blew away competing scores from Gigabyte's i-RAM drive, as well as the scores of any conventional drive or RAID of drives based on spinning platters (go figure).  In the final tested benchmark, PCMark Vantage, the Z Drive outputted scores of more than 125 MB/sec. for all its hard drive tests.  At the top of the scale, the Z Drive capped out at a speed of 507 MB/sec. on the application's Windows Media Center test.  The Z Drive achieved an overall PCMark score of more than 43,000 points--that's downright fast, even without any other point of comparison on the tested PC.
