SSDS are both a break with the past and a category of products evolving. For users accustomed to performance today all relating to conventional hard drives, it is often unnecessary to look far to find considerably better: the simple DSS interfaced in SATA are often capable of speeds exceeding 3 GB/s. In this range, it would be difficult not to recommend the last models Crucial and OCZ and more particularly the OCZ Vertex 3.
Always in the field of SATA SSDS, we begin to find more in addition to model controller based on SandForce SF-2200, and they already announced as future reference on the subject (at least when bugs have been eliminated); the Crucial m4 is probably the least expensive product in this category. But in any event, it is clear that the ceiling is the SATA 6 GB/s is not yet close to represent a problem in the segment of desktop computers.
Of course, there are still performance enthusiasts who want more; But if the SSD 2.5 "current are not fast enough to meet your needs, you have choice to divert you the SATA and its bandwidth limited to 600 MB/s. If allow you your finances, you may have the eye on a connected to PCI Express SSD or a cluster SSD RAID connected in SATA; in both cases, you can say goodbye to the support of the TRIM on Windows. Among the models of this type (planned for workstations), the OCZ RevoDrive RevoDrive X 2 include and probably best-known, for the simple reason that they can be used as a boot drive, which is not always the case in this category.
The problem of these two products is that they are built on the same controller that the OCZ Vertex 2, while it is now on the market the 3 Vertex, appealing to the second generation and whose performance SandForce controller exceed those of the PCI Express models as is RAID. What's more natural for OCZ, therefore, renew its range and launch today its RevoDrive 3 X 2, a product based controller SF-2200 and whose announced performance are worlds away from what we have seen so far, as shown in the table below:
Vertex 2 E
RevoDrive X 2
Vertex 3
RevoDrive 3 X 2
Max sequential read throughput
Flow rate Max sequential write
Blocks of 4 KB random write
The secret of these impressive figures? OCZ indicates that the RevoDrive 3 X 2 contains a PCI Express to SAS controller (against a controller PCI - X to SATA for RevoDrive X 2) and four second generation SandForce controllers.
RevoDrive 3 X 2 is therefore to Vertex 3 RevoDrive X 2 was the Vertex 2. The names have more sense when we know that the first Vertex contained an Indilinx controller; the Vertex 2 / RevoDrive were built around a first-generation SandForce controller Vertex 3 / RevoDrive 3 were passed to the second generation of the controller.
For storage, difficult to not be enthusiastic specialists! If you saw the video online by our friends from Engadget, RevoDrive X 3 is the first consumer SSD (LSI and Fusion-io are intended for businesses and therefore are not here) to promise speeds beyond 1 GB/s.
Unfortunately, if you are specialist storage, you know also that the fastest models are also the most expensive. If a Vertex 3 is already given, the equivalent of several Vertex 3 on a PCI Express card is even more. It's clearly a performance-oriented product, and those who wish to access will pay dearly.
Things are now clearly developed, is a series of important issues. How the RevoDrive 3 X 2 manages to display astronomical performance? Is it really his promises? Fixes the compatibility problem highlighted by Chris in his article OCZ RevoDrive X 2: faster than the SSD SSD?
