OCZ debuts 510MB/sec, 1TB solid-state drive

updated 03:45 pm EDT, Fri April 24, 2009


OCZ on Friday took its turn at the new class of RAID-striped solid-state drives and launched the Z-Drive. Like offerings from Fusion-io, the Z-Drive ties together four SSDs to a central RAID controller and plugs into a PCI Express slot, eliminating the bottlenecks of SATA and transferring data twice as fast or more than single SSDs. OCZ claims peak read speeds of 510MB per second and peak writes of 480MB per second for its top-end drive.

The earliest versions of the Z-Drive will have either 250GB, 500GB or 1TB of storage, but all models have 256MB of cache to keep data moving. They work with Mac OS X, Windows XP and later operating systems. Drives should be available soon; their cost isn't known, but OCZ promises that the line will be "priced aggressively" to be affordable to high-end home users rather than just professionals.

    A four-drive striped array? What's the mean time between failures for SSD drives? Because this setup will reduce it by 75%.

    there is pricing on mwave... they must define priced aggressively different than i do.

    not that it is a bad deal all things considered. but it is hardly mass market pricing... even for "high-end home users".

    250GB : $1559
    500GB : $2399
    1TB : $3759

    Mean time between failure

    Taking into account that most SSDs have a MTBF of 50-100 years, a 75% reduction does not seem impractical. At minimum, that would be 10 years, probably 25 - in electronics lifespan, thats eternity.
