Just remember that Trim doesn't work in raid and your drives are full of garbage from reading and writing to them, if the drives are new enough they may have on-board trim in each drive....whether or not that it works in raid I don't know. Plus you should have shut off defrag, that will deteriorate the drives even faster.
I wasn't aware of the TRIM issue. It looks like it's expected to be available in the near future for RAID 0, though I didn't read anything conclusive. Fortunately I have my OS and selected applications on the SSD's and keep all of my profiles and data different drives. So there is less writing and deleting going on on the SSD's than "normal". Still, perhaps I"m starting to see the effects of this issue. Thanks for the info!
Defrag has never run on my SSDs, fortunately...oddly I went in to double-check and it had never run on my primary data drive either..doh! Only 8% fragmented, but still - running that now
