More details and images of Asus' ROG RAIDR Express have surfaced.
They were first spotted at CES back in January, but the folks over at SweClockers have managed to get a couple more images and a nice big spec sheet.
As was already clear earlier, the RAIDR is an SSD in a PCIe form factor, with support for the PCIe 2.0 x2 interface. It carries two SSDs in a RAID 0 configuration, which are each based off a SandForce SF2281 controller, running Toshiba-built 19 nm MLC NAND flash memory.
Because of the way the RAID array is built by Asus, the ROG RAIDR does support TRIM commands, SMART, and NCQ regardless of being a RAID 0 based SSD. Normally, when tweakers attempt to build a RAID array with two SSDs through the motherboard, these functions won't work. Moreover, the controller hides the RAID 0 array from the system, therefore not requiring any F6 drivers, appearing to be a standard AHCI controller and a single disk.
To start out with, Asus will launch two models, a 120 GB version and a 240 GB version, which offer sequential read speeds of up to 765 MB/s and 830 MB/s, and write speeds of up to 775 MB/s and 810 MB/s, respectively.
