I chose to go with the OCZ 30gb in RAID. Why?
1. I contacted a support person on the OCZ forum and they assured me that on their drives with the newest firmware, garbage collection/Trim works in RAID.
2. I hackintosh so SSDs that do Trim are useless to me (OSX doesn't support Trim) as are drives that just do garbage collection in NTFS.
The OCZ drives to a file system agnostic garbage collection, so it works good in OSX or Linux. In fact, that is why OCZ is the only brand that has "Mac" version of SSDs, even thought the guy on the forum told me they were the EXACT same thing as the non-Mac versions at a higher price. Companies just can't help themselves from milking an extra margin out of Mac idiots who think that the Apple has to be on the box for stuff to work.
With all that said, the Intel drives are DEFINITELY faster on writes (even after RAID) and honestly an 80GB Intel drive probably beats both in a RAID due to the way SSDs work.
