It's TRIM support not TRIP support.
TRIM is not supported using any Raid controller or any onboard motherboard RAID. I've been trying to do this as well. I hear people say that 160GB is faster than a 2x 80GB running RAID 0 and has TRIM support. Would not recommend going for RAID just yet. Some people report that the gains and loss cannot be "felt" during normal use. With that said, I'd skip the RAID and just get whatever size you need to by pass the RAID because the headaches that come with it isn't worth it.
P.S I bought myself a RAID card before I knew that TRIM is not supported. Have to wait for Adaptec to generate some driver. God knows how long that will take. Some RAID card don't even support Windows 7 either.
Don't go RAID! Not worth it. Take that $150 that you might spend on a controller and invest in a bigger SSD.
Ah, sorry about that I must have been really tired when I wrote that. :O
Anyway the idea is coming from test's I've seen on SSD drives where commercial ready solutions of Raid 5, where 4 disks are hidden in a chamber directly on a PCI-ex Raid controller. "PhotoFast G-Monster Promise PCI Express" It was much better than all single drives in some aspects, but was beaten hard by X25-M in all other. The idea was to gain the advantages of the PhotoFast solution without sacrificing the overall performance of the X25-M.
I have seen many tests of RAID 0 arrays using X25-M reaching over 300mb/s read, but if the RAID compromises other aspects maybe the use of it is limited as you say.
What? Trim with RAID is not supported? Now you tell me! I just got my two 80GB Intel SSDs today and was planning on using them as RAID1. I am using a new Asus P7P55D-E motherboard. Does this mean I am out of luck? This may be a dumb question, but will this ever be supported? And what would need to be updated to support this (firmware, RST, Win7)? I guess I could get by with just one drive, but the security of RAID1 was nice warm fuzzy.
Second thought: Would it be wise to set up a RAID1 now and hope for TRIM support later?
