AS-SSD BenchmarkAlex Schepeljanski of Alex Intelligent Software develops the free AS SSD Benchmark utility for testing storage devices. The AS SSD Benchmark tests sequential read and write speeds, input/output operational performance, and response times. Because this software receives frequent updates, Benchmark Reviews recommends that you compare results only within the same version family. Beginning with sequential read and write performance, the 120GB OCZ Revo PCI-E Solid State Drive produced 393.05 MB/s read speed, and 185.54 MB/s write performance. The sequential file transfer speeds have traditionally been low with this benchmark tool because of uncompressed data, especially with SandForce controllers, which is why we will concentrate on the operational IOPS performance for this section. Single-threaded 4K IOPS performance delivers 23.21 MB/s read and 63.28 MB/s write, which is similar to a single SandForce-driven SSD but still among the highest results we've recorded. 64-thread 4K reads recorded 221.92 MB/s, while write performance was 170.45 MB/s... both earning the OCZ Revo SSD a spot among the top performance results in our charts.
Displayed in the chart below, the 64-thread 4KB IOPS performance results for several enthusiast-level storage products helps to illustrate which products offer the best operational input/output under load:
Compared to the 228/143 MBps 64-thread 4KB IOPS two separate SandForce SF-1200 SSDs in RAID-0 produced, the OCZ RevoDrive matches read performance and heavily outperforms in write operations. Drive Hardware
In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.

Comments
They have certain bandwidth restrictions on the PCI-E bus with multiple PCI-E slots occupied concurrently. (X16 is divided into X8 times two)
I just wonder if this architecture would effect the output of the drive, and if the drive would effect the output of the Video Card?
PARECE QUE VAO MUDAR A TATICA!
Aside from the tranlation, can someone tell me if this type of storage( via Pci-e)is bootable??
I'd guess quite a lot will need bios updates.
I notice the idle power consumption on the data sheet provided by OCZ is 7W. Although still small, it seems to be much higher than other SSDs. Is this correct? If so, is it an artifact of having two controllers on the card or of being a PCI-E footprint? Any idea?
I agree with you about the controller; it works, but better options exist. Perhaps it was a cost benefit issue.
@ Neil: OCZ doesn't recommend motherboards with restrictive bandwidth on the PCI-Express bus, and the P55 motherboard would be a concern if SLI or CFX were used. If it's a single VGA with Revo on P55, I don't see a problem.
@ Robert: A standard SSD has a controller and NAND, while the Revo has twice the amount of NAND ICs, a RAID processor, and PCI-E bridge. This is where the extra power consumption comes from.
