Now I don't know if you can keep TRIM, but I always use the largest strip available. More caching=faster speeds.

Good to know.  It was mentioned that Intel released a new driver with TRIM support in RAID, but P55 chipsets are not listed as compatible.  The ones I listed are newer, and have P55 listed as compatible chipsets.  I'll probably need an EVGA tech to answer that part.

 
i was so happy when i saw that intel intergrated raid and trim but thats only on their board and its not full blown trim. its like a hybird when i was looking it. basicly if you have a GREAT garbage disposle on your SSD it will be like full trim support.
 
I contacted the Kingston tier 3 SSD support, they said  as long as you turn off all the extra writing on your disk raid should be ok.
 
as of now you have to choose, keep the drives for an extra 6-10 months or get insane speeds.
 
vertex 3 in raid 0 was my plan until hyperX droped price in nearly half. just remember SSD slow down not completly die out. the speed diffrence probably will balance out the non trim support as long as you turn off all the extra windows writting to it.
 
OCZ's gabarge collector seems to standard hopefully will improove with firmware updates.
in a year they wil probably be some insane SSD and you foget about ur vertex 3. worst case a year and half.

- No trim in any R0 config, no matter what ssd's are used. Trim commands are passed to a single drive under  raid array but not part of the array.
  - My drives have never ever seen a single trim command, been in some R0 array since the day I bought them.
  - GC is much better than trim and will maintain performance over time very easily, at least on Crucial drives.
  - As to stripe size 64k and 128k are the standards but you can go all the way down to 4k. If you want to find out which is better for your drive you can setup the array, but leave it blank. Boot into windows from another drive and try some bench runs on the array.
  - SSD's will pretty much scale 100% when you go from 1 to 2.
