OCZ RevoDrive - Introduction
OCZ has been on the cutting edge of SSDs since they hit the consumer market and are on the pioneer trail once again with their most affordable PCI-Express based SSD yet - the RevoDrive. As implied, this isn't their first PCI-E drive but it is the first that carries a price tag that rivals that of the more traditional SATA port based SSDs. At an MSRP of $349 for the 120GB version, they aren't what you would consider inexpensive for storage devices in general, but considering the performance, hardware onboard and pricing of similar capacity SSDs, the price point is rather impressive.
The RevoDrive features a pair of Sandforce SF-1200 controllers in a RAID 0 configuration - all on one card. Think of it like the NVIDIA SLI and ATI Crossfire cards with dual GPU's on one card. You get all the benefits of a traditional RAID 0 configuration without the hassle and expense of multiple drives and add-in RAID controller cards. We've seen the performance of just one Sandforce based drive begin to hit the SATA II bandwidth ceiling, and moving to a higher bandwidth interface will really allow the RevoDrive to stretch its legs.
The trade-off for this extra bandwidth and speed is TRIM will not work with RAID configurations. Nor will idle garbage collection. Before you run off screaming, this is not as bad as it seems. Normal use shouldn't see an appreciable performance drop-off for quite some time although the more full the drive is, the more it will affect long-term performance. After banging on the drive with a battery of benchmarks for many hours (not recommended), I saw some impact on the scores but nothing alarming. With the over provisioning and DuraClass technology, the Sandforce controller does a nice job of maintaining performance over time. Rumor has it that OCZ may be developing a TRIM tool specifically for their PCI-E based RAID drives; although, when that might be is anyone's guess.
