It's been quite a while since we've seen an update to the RevoDrive product family. The last all flash model we tested was the RevoDrive 3 X2 480GB. That drive shipped with four LSI SandForce SF-2281 controllers and 512GB of flash with an MSRP just north of $1,600. The new OCZ RevoDrive 350 480GB we're testing today cuts the price in half for the same capacity size and doubles the PCIe bus interface speed by increasing the number of PCIe lanes to the host. The RevoDrive 350 isn't the first RevoDrive branded product to use Toshiba Toggle flash, although the RevoDrive 3 Max IOPS was a fairly rare model.
The RevoDrive product family is for prosumers, power users, and enthusiasts who demand the highest levels of performance. RAID 0 based products perform remarkably well at high queue depths and under heavy loads. Sadly, some of the tasks we do every day, the consumer tasks, can actually run slower with these products than expected. The trick to achieving the highest performance is to run workloads that take advantage of high queue depths. Some of the tasks include batch photo editing, audio / video production, multitasking consumer workloads, and VM systems.
Specifications, Pricing and Availability
The new RevoDrive 350 ships in three capacity sizes, 240GB, 480GB, and 960GB of user available capacity. The 240GB model has two LSI SandForce SF-2281 controllers, while the 480GB and 960GB double the controller count to four. The controllers link back to OCZ's VCA 2.0 controller that bridges the SATA to PCIe bus. The RevoDrive 350 is the first RevoDrive product to use eight lanes back to the host system, twice as many as previous generations.
Today, we're testing the 480GB model with up to 1800 MB/s sequential read and 1700 MB/s sequential write speeds. Random performance for the 480GB model comes to 90k IOPS read and 140k IOPS write. OCZ rates endurance at 50GB per day for three years, the length of the warranty.
The RevoDrive 350 supports TRIM through SCSI unmap, so your idle time will help keep performance high when not hitting the drive with data writes.
The press deck included MSRPs for the new RevoDrive 350 family. The 240GB lists at $529.99, 480GB at $829.99, and the 960GB at $1,299.99. The prices are higher than purchasing two or four 128GB SSDs, but the RevoDrive is more than just a few SSDs slapped together. The drive has an onboard RAID controller that works with OCZ's Toolbox and simplifies installation. Intel's current prosumer / entry-level workstation chipset, X79, only has two native SATA 6Gb/s ports. The RevoDrive offers X79 systems the ability to run a high performance storage system without hassle.
