Would Raid 0 Sata II be worth it over unraided Sata III?

I have two spaces in my PC case for SSDs using the akasa 2 SSD converter in the floppy drive slot.

My Rampage III Extreme also has two marvel Sata III ports, but these dont run any faster with raid, but do provide 366 mb/s read speed on my 64 Gb crucial C300.

I decided to pre order the £119 Adata drive and use it in the second Sata III slot. My 64 Gb C300 is good enough for my boot drive, and then I can use the Adata drive for whichever games I currently play.

However I'm now wondering if getting two of them and running them in raid 0 on the sata II ports as both my OS and gaming drive would be any more beneficial over running one seperately on sata III.

Space isnt really the concern, just whether I would see any benefit from two of them in raid 0 on sata II vs a single drive on sata III.

I'm considering throwing my money away to grab a pair of them while they are £1 per Gb. Also the news that Intel are adding trim support to SSDs in raid makes it even more appealing.

The max speed of a single drive on your SATA3 port - 366MB/s?

Moving a drive to SATA2 port is going to top out at 250-300MB/s. So in moving to RAID0 with two drives you'd get 500-600MB/s... theoretically. Less any overhead in the raid controller and timing differences between the two drives.

Depends on whether spending 100% more is worth it to you.

Jumping on the thread here with a similar question but, I am considering two 120-128 SDDs and running them in RAID-0 on my SATA 300 only motherboard rather than a single 240-256 drive.

Apparently the Nforce controller on my board (see sig) would give me the full 300mb/s on each port.

The thing I am worried about is the lack of Trim in that scenario.

Is one of the Marvell/Sandforce/Intel or Indlix controllers better in non TRIM environments i.e. RAID ?

The marvel controller on my mobo has the equivalent max bandwidth of a 1x PCI-E slot, which I think is around 50m mbps. 366 mbps is the maximum speed that my crucial C300 runs at.

I think im not going to bother with the 120 Gb drive anymore and carry on gaming off my raid 0 HDDs.
