OCZ Colossus (internal RAID-0) SSDs and TRIM?

[mgrmgr]

I tagged this question onto Anand's latest great SSD treatise, but am repeating it here hopefully for greater discussion...

Any idea if the (mid-Sept release?) OCZ Colossus's internal RAID setup will handle the problem of RAID controllers not being able to pass Windows 7's TRIM command to the SSD array? I'm intent on getting a new Photoshop machine with two SSDs in Raid-0 as soon as Win7 releases, but the word here and elsewhere so far is that RAID will block the TRIM function.

Would a Colossus 128GB solve that problem?

I assume OCZ will have handled the problem of updating firmware if one is running a RAID-0 pair. If the sell it as a "single drive" they must have a reasonable way to update firmware..but does anyone know for sure?

I know it's early, but...

No idea if Colossus will be TRIM compatible out of the box, or even at a later date with firmware updates, but to be sure there is nothing about raid that outright precludes TRIM functionality...it simply requires a raid controller chip that is capable of passing along the TRIM command to the flash controller chip and having that controller chip be TRIM aware (firmware) that such commands are coming to it.

Given that OCZ is acutely aware of the necessity of TRIM, it would be a colossal mistake IMO for them to create/release such a product without TRIM capability (either at time of release or planned upgrade in future firmware release).

I think that Trim also needs to be supported in the driver. That is why the same chipset supports Trim in single drive mode but not in RAID mode. A different driver is used depending on what mode the chipset is in. I wonder if Intel is waiting until their drive supports Trim until they update their driver to support Trim?

From the OCZ forums:

"The cache is per Indilinx controller, EG 2 controllers 128, 4 controllers 256.

Been told drives will have GC and TRIM pass thru, i have not tested one yet though."

Much appreciate the three replies. Yes, it would certainly seem like a "colossal" mistake if the drive can't deal with firmware updates, GC, and TRIM. Thanks especially to dali71 for passing along the info that the Colossus should have this. Any time frame on when you might get one to test?

On paper, the 128GB looks like a really great drive and price. (It makes typing hard, but) I'm keeping my fingers crossed.
