2 90GB Force SSDs in RAID-0 vs. 1 180GB Force w/Trim Enabled

Hi,

I'm looking to upgrade the original HDD in my Dell Workstation 690 and have decided to go with a Corsair SSD. However, I'm torn between running a single Force 180GB or two separate 90GB drives in a RAID-0 configuration. There isn't much price differential, so which will provide better performance? I hear the RAID-0 configuration will be much quicker out of the box but will deteriorate as TRIM cannot be enabled in RAID configurations - is this the case? Or can TRIM be enabled with a RAID configuration? Does getting a single SSD where I can enable TRIM make more sense?

Thanks for your help.

You cannot use TRIM on RAIDed drives.

RAID 0
+ Faster speed
- 2 pieces of hardware = 2 possible failure points

Personally I'd go for the bigger drive.

Note: No one refers to the drives by their unformatted sizes :) I'd get the 160 GB or the 240 GB.

Pros and cons either way really, raid0 with the force drives have nearly twice the sustained transfer rates, but how often do you transfer huge files to an os drive? you buy the ssd for seek time so it wouldn't be a bad choice to get the single drive then add another once raid trim comes out.
