Thread: OCZ XTwo 240 Gigabyte PCI-convey solid-state drive

The solid-state drive market proceeds to develop at a quick pace and competition is beginning to heat up once again. While there was once only a some controllers worth picking from, half a dozen viable options take the market yet. The introduction of the Marvell 88SS9174 controller utilized through the Crucial RealSSD C300 stirred things up, when the currently freed Samsung S3C29MAX01, utilized exclusively in the Samsung 470 series SSDs, furnished now another excellent choice for clients.


Though a lot of attention is being garnered through these latest products, the majority of solid-state drives are even based on the renowned SandForce SF-1200 controller as it provides some of the best performance, and it is not worse in conditions of costing either.


Though there are more Sand Force founded drives than we care to count, the most notorious would have to be OCZ's Vertex 2. OCZ was fast to jump on the SandForce bandwagon, creating the Vertex 2 between the first to ship with this controller. Since then, the company has freed many products founded on the SF-1200, adding the RevoDrive.




First declared back in June, the actual RevoDrive conveyed not one, but 2 SF-1200 controllers in RAID and boasted up to 80,000 IOPS (Input/Output functions each Second). It established in capacities ranging from 50GB by 480GB. The 50GB example flaunted sustained information transfer velocities of 350 MB/s while sequential read velocities were claimed to be as high as 540MB/s.


As effective as the first RevoDrive was, the follow up example we are trying now fully blows it out of the water. Less than 2 months before, OCZ declared the RevoDrive X2 effectively doubling the number SF-1200 controllers utilized in RAID and arriving in sizes from 100GB by an insane 960GB.


The extra controllers boost sustained write velocities up to 600MB/s with sequential read/write throughputs arriving at 740 and 720MB/s. Moreover, the RevoDrive X2 is told to be capable of an amazing 120,000 IOPS.


Dissimilar traditional solid state drives, the RevoDrive XTwo is a PCI-Express solid-state drive. That means it does not rely on the SATA interface, creating it so different from last products that we have reviewed, so let's dive in for a closer look.
