Sandforce Drives and R0? Maintenance possible/needed?

[jcool]

Hey guys,

Anvil's SSD testing has me craving a pair of SF-1200 50GB SSDs in Raid 0 for my OS partition (Win7 Pro x64) - OCZ Vertex LEs are in stock at my local distributor's for 150€ a piece (w/o taxes), and I am about to purchase them.
Just a few questions beforehand, as I am only familiar with Intel, Indilinx and Jmicrap-based drives:

1. These drives support TRIM, but since there is no way to pass on the TRIM command in Raid 0, is there another way to do "maintenance" on those drives? Like GC for Indilinx?
2. Do they even need maintenance, or are they pretty much "stable" performance-wise like the X25-Ms? Of course I am aware of the "do an image, wipe drives, re-load Image" procedure but I'd like to keep this to a minimum (like once a year tops)
3. I am currently running a single 60GB CSX Q2 SSD (Indilinx) which supports GC. I've freshly set it up with Windows 7 a few months ago, so it is properly aligned. Can I just clone that Image to the new Raid 0 or would that be a bad idea performance-wise? No clue what Win7 uses for default Offset, or what I should use for 2x Sandforce drives in R0.
4. What Raid stripe size should I use? I remember 128k worked best for 2x Indilinx in R0.

Controller is the ICH10R (GB EX58-Extreme/evga E760, soon to be Classified SR-2), no LSI 92xx for me (yet)

Thanks guys!
