I am planning a Sandybridge build next month and have a question about SSD's.I currently have Windows7 and some of the major stuff by Earth Simulations, GEX, Active Sky, Meaga Scenery, Flight 1 etc on a Crucial C300 SSD attached to a 6GB controller and fsx on another C300 also attched to sata 6.I have managed to buy another C300 (off a mate) and as my install of fsx currently only has 19GB of free space left and the C drive 39.5GB I was planning on either running two C300 in Raid 0 on a marvell controller (on a new B3 Sandybridge Board) and the C drive on the intel controller, or just both C300 with fsx split between the two with the large scenery add ons etc on one and the rest on the other.As I have never gone down the RAID route before I would like some advice.Also with all this talk of achi being better for ssd's does anyone have any direct experience of this as I would need to sort that out before the Win7 64 bit install apparently.I do hope this all makes some sense!

Ahci is better used with SSD's, but you can activate it without reinstalling W7: http://www.ithinkdiff.com/how-to-enable-ahci-in-windows-7-rc-after-installation/As for SSD raids, I think there's still no way to get TRIM to work with SSD RAIDs (somebody correct me if I'm wrong) so I'm not sure it's a good ideaAhci is better used with SSD's, but you can activate it without reinstalling W7: http://www.ithinkdiff.com/how-to-enable-ahci-in-windows-7-rc-after-installation/As for SSD raids, I think there's still no way to get TRIM to work with SSD RAIDs (somebody correct me if I'm wrong) so I'm not sure it's a good idea

Trim command will NOT work with SSDs in Raid 0. Unless the manufacturers develop a way to delete the garbage, you will need to back-up and restore.That said, depending on the controller, it will take a long time to degrade the drive.

Don't use SSDs in RAID configuration, rather get smaller SSDs and put the OS on one, FSX on the other, Sceneries on third, etc.When using mechanical drives, the primary reasons for RAID are fail-safe reliability (RAID 1 and 5), sustained read-write speed for RAID 0, or both advantages at the same time in more complex nested RAID arrangements such as RAID 10 (1+0) or RAID 50 (5+0). Note that access and seek times are not improved whatsoever by any RAID array configurations.SSDs don't really break-down (you should still back-up, though, as a virus could wipe your drives or other misfortunes and calamities could subject you to data loss), so the fail-safe reason for using RAID is no longer there. For practical purposes, SSDs have zero access and latency times (actually seek and latency no longer even exist for SSDs), so you have a big gain there, leaving the sustained transfer rate of parallel HDDs as the only advantage a RAID 0 array could give you (but only when transferring very large files, otherwise the advantage in the seek and latency of SSDs with the more common smaller file sizes would mean the sustained transfer rate advantage of a RAID 0 array could very well get swamped by the zero seek/latency of SSDs.Cheers,- jahman.
