I figured I'd upgrade one of my RAID's recently in my box that I use to manipulate video - I constantly move 4 GB + files around on this box. So i bought a couple Seagate perpendicular based HD's that use the new 3 Gb/sec connections and wow! Low and behold, it hit 111 MB/sec sustained!!! Wow! I'm blown away by that!!! Here are some #'s so that you can compare! I'm still a little in shock if you can't tell. My old RAID was already pretty impressive at 80 MB/sec sustained.
