I'm planning on using a pair of these as my boot drive in software RAID0 configuration. Doe anybody know of any issues / pitfalls there may be with this?
RAID 0 is pretty silly for a boot drive, unless you want to double your chances of drive failure-
there are other things you should use fast drives for (scratch, data/working drive) before the boot, see here for some thoughts

Amen to that.
Mac Pro + spending money on boot drive(s) - waste .
8-core Nehalem....400MB/s of drive read bandwidth....starting Leopard. If you do it, time the boot with a stopwatch. I want to know if you can go from a cold start to the login window in under 5 seconds or not. (I've heard tales of under 10 seconds off a single drive)
The quickest thing I've ever seen was on an ASUS board, where they stored an OS on the board via a firmware chip. ~5 sec. The OS is stripped, but it works. Fastest cold start to internet browsing/email I've ever seen.8-core Nehalem....400MB/s of drive read bandwidth....starting Leopard. If you do it, time the boot with a stopwatch.

More did you use a RAID card or just software RAID for this configuration?My system drive is 2x X25-M in a RAID-0 config and it's hands-down the best investment I've ever made. Every other traditional hard drive based system feels like a snail.

Everytime I read one of these threads I laugh.
If anyone has ever used a Mac Pro with either one X25-M or dual X25-M drives (RAID-0) they'll know that it's the greatest performance boost to general system responsiveness and operation you will ever experience.
If you boot it up open a bunch of apps and shut it down 50X per day with a stopwatch in hand, then SSD will yield benefits.
If you boot up once per day and actually use your machine to WORK within an app on images or graphics files, then I dispute whether a fast boot/app drive does anything to improve your workflow, and the money would MUCH better be spent first on RAM, then on a fast array for your scratch disc(s) and data drives.
Thanks More. Were they difficult to install with the Maxupgrades kits?
From barefeats (who have, in-lab, MANY more SSD options and much more thorough benchmarking than any individual here):
"THE STATE of SOLID STATE
There is much interest in using Solid State Drives (SSDs) for boot drives. With the exception of the Intel X25-E, the write speed of SSDs is unimpressive. Also the price needs to come down and the capacity go up for SSDs to be practical as OS X boot drives.
On the other hand, for Professional photographers who use Adobe Photoshop edit RAW photos with lots of layers, a pair of 32GB X25-Es in a RAID 0 set as a dedicated scratch volume is very attractive, producing up to 500MB/s read and 340MB/s write. If you need more capacity, Intel is supposed to start shipping a 64GB version by March 1st, 2009. "
Another words, if you really have money to burn, and feel the need to put it into the diminishing returns proposition that is SSD, use them for the right thing (which is not a boot drive).
Put everything on a single wickedly fast RAID0 SSD array and be amazed.
Just done some timed tests with booting and launching CS4 apps.
Boot (from start-up chime): 15.8 seconds
Photoshop CS4 launch (cold*): 1.8 seconds
Illustrator CS4 launch (cold*): 2.2 seconds
InDesign CS4 launch (cold*): 4.0 seconds
*cold = first launch of the app from a system restart.
I'm using Apple's good old software RAID solution in Disk Utility. Does the job nicely
