I have two Corsair sata3 180gb SSD'S that I want to set up in Raid 0 for my primary OS drive. What can I expect for read/write speeds and they will be connected to the sata3 ports. Currently I have my OS on a RevoDrive X2 that gives me 740gb/s read and 720 gb/s write. I am thinking the two sata3 SSD'S in raid will give better read/write performance ?
It's sure a lot faster running (2) SSDs than the PCI RevoDrive. The read/write speed are doubled from what I saw in some of the CrystalDiskMark results posted at overclock.net. A single Crucial M4 128 Gb SSD for example (with the latest 0009 firmware version) typically gets you 500 MB of sequencial read speed. It's doubled if combining another same SSD on RAID 0 array. The sequencial write speed is also doubled. TRIM is no longer a problem as the SSD's Garbage Collection (GC) feature works with RAID array.
I'm planning to get another Crucial M4 128 Gb SSD to run on RAID 0 because of what I saw in the result.
