- PCIe 2.0 x 2
It is a beast, watchout with AMD APU 08/27/2013
This review is from: ASUS ROG PCI-E 240GB PCIe 2.0 x 2 MLC Internal Solid State Drive (SSD) RAIDR Express
Very very fast, and works with a 6800K on a GA-F2A85X-UP4 (has UEFI) temporarily (see the cons below), but will be installed into a more powerful future machine using a 4770K.
Read and write speeds are ~660 MB/s for read and 500 MB/s on write for crystaldiskmark (ROG) in Win 8 64. Transfer speeds in ATTO from 1024 through 8096 are consistent with 780 MB/s write and 816 MB/s read.
Buy this with the knowledge that it cannot be refunded by Newegg once it is shipped - read their policy.
Watch out if you are pairing with an APU, you cannot use the x4 slot on ATX motherboards (bandwidth shared among all other devices linked to FCH or older term, "south bridge"): crystalmark results and file transfer rates in Win 8 (64) will be significantly lower, while ATTO will be unchanged. Thus you need to run it on one x16 sized PCIe slot: splitting your the bandwidth to x8 x8 if you are using a PCIe GPU concurrently.
PCIe ssd appears to be the future. Some other manufacturers aimed towards the server market have them already on x4 (PCIe 2.0) and higher laned slots (they will cost closer to $100K when you find them now). I can see this device lasting at least through 2018 as a primary drive, and coupled with a 32 GB (DDR3 2400MHz) RAMdisk at the same time. By then, an ssd will be likely be significantly faster and cheaper.
