I just picked up 2 super talent sx 64gb ssd and running raid0. They are the newest thing from super talent.They use the new samsung 8 channel controller and have a 128mb cache onboard.They are rated for 200MB read 120MB write each.I got them at newegg for $173 U.S.
performance is awesome, none of the problems earlier ssd's suffered from.They might not look as flashy as some others, but they do perform at advertised speeds without a hiccup.Windows 7 boot time for me 8sec.
Just a thought for those thinking of investing in ssd
