You don't have TRIM on drives in an array. On any controller. But you can run in RAID mode on an ICH10R and still have TRIM on a single SSD.

This. RAID = AHCI + RAID capability.

p.s I use the intel storage manager. pic to come, but im off to uni now.!!

This is faster

Pretty sure 2 Vertex 3's (they are 500mb each, right?) in RAID 0 beat the Revo x2.. cuz, you do know the chips on the revo drives are setup in RAID 0 and thats how they get the speeds. Also, with vertex 3's, you won't need to worry (as much) about whether it'll work on your board (PCI-E drives don't work on all motherboards).

OT:
Is this thread essentially saying this?: RAID setting in BIOS = AHCI if used with one drive?
I have a question similar to this as well.

The problem is this
If controller 1 is set to RAID, controller 2 can ONLY be set to IDE or RAID.
If controller 2 is set to RAID, there is no other option then RAID for controller 1.
No available AHCI setting in conjunction with RAID.

Seeing as I currently have 4 HDD's in RAID array's, I have run into a problem with the Vertex 2 I've won.

2 Vertex 2s in RAID match the Revo but cost less - all the Revo is underneath is 2 Vertex 2 drives in RAID0 coupled to a cheap ass 8 year old PCI-X RAID controller, then to a PCI-X to PCIe bridge chip, which then (usually) connects through the ICH10R anyway.

A single Vertex 3 matches (or is close to) the Revo - you don't need 2.

Yes - if you are in RAID mode, then you are also in AHCI mode (RAID is a subset of AHCI, and AHCI is required to run in RAID mode). You are fine to use your RAID0 and your single Vertex 2 together, and you will be able to use TRIM on your SSD.

If you ran 2 Vertex 2s in RAID on the same controller however, you would not get TRIM at all - it doesn't work on drives in an array.

This is also the reason why you don't get TRIM on the Revo - the drives are already RAIDed, and no controllers (currently) support TRIM in RAID. And if I'm honest, I don't believe they ever will...

I think you might want to take those things out of RAID. Before you destroy them.

Thanks for the detailed answer! It relieves some stress xD

I only used 2 vertex 3's in RAID 0 to compare to the RAID 0 on the RevoDrive
I know a V3 is almost as fast in of itself.

That just means TRIM is enabled on the system - it doesn't mean it's working. You can use the same command on a system with no SSDs present and it will return the same value - doesn't mean you can TRIM your mechanical drive. There is no way to tell if it is actually working - but if you hop over to Intel's site you'll find out that their controllers don't actually allow TRIM in RAID, which should give you a little clue as to whether or not it is working...

This.

Just because the OS is sending the command doesn't mean the drives are receiving it, let alone honoring it.

I put degradation of performance and "destruction" in the same basket. When you poison a system's ability to operate at full potential, you are destroying its performance. You may not be physically destroying anything, but substandard performance is no better (to me). Sure, you can get the drive back by just refreshing it, but then you have to go through the hassle of backing stuff up. Why make life difficult?
