I had set up a RAID 0 in my MacBook in order to squeeze some extra life into Aperture. This was with 2 Seagate 500GB 7200rpm drives. Seems that the idea was a good one but didn't take into account the processor overhead needed for the software RAID. The performance of my system actually decreased even though disk activity increased. I ran GeekBench and XBench. The GeekBench tool gave me 1507 with the RAID, and 2768 without it. Xbench was 113.97 without the RAID, and 83.84 with the RAID. Uncached Write/Read scores were all higher because of the RAID but like I said overall system performance took a hit. I did this because I didn't want to buy an SSD at the moment. Was wondering if I would get any gains from the RAID 0. The upside to all this is that I have a backup drive in my laptop next to the main drive, and when I do get the SSD, the secondary drive is already in there waiting for when I transfer my image and music libraries. Anyway just thought I would let everyone know. Enjoy the picture.
