As many of you know, I've had a couple of Gen1 80GB Intel SSD's in software RAID0 in my Mac Pro for many months now... and I'm a huge advocate of SSD's to the point of becomming obnoxious about it around here I also use the stock 1TB Black that came with my Mac Pro for archiving project work. In addition, I have a 1TB Time Capsule I use for backups. As you can imagine, that empty drive bay in my Mac Pro was driving me nuts... just begging for another SSD to slot in there. In addition, the 160GB of my dual drive array was getting a little strained and either needed some serious house-keeping or some additional capacity. Both of these problems were solved recently when I saw a Gen1 SSD for sale on Craigslist... I couldn't resist. Since I had to rebuild the array anyway, I thought it would also be a good opportunity to both secure-erase the old drives and also install Snow Leopard and all my apps from scratch since it's been many months since either had been done. You can read all about the process I used to secure-erase the drives in this thread. Here's the results... Note that the anticipated ICH limit of 600+MBps seems to be a reality as AJA's max read is 623MB/s compared to what should be closer to 750MB/s for three Intel SSD's. The write throughput is as expected... about 3x70MB/s showing that the drives and Mac OSX software RAID0 scales directly with the number of drives in the array. Xbench, which hasn't been updated since 2006, and whose results are terribly inconsistent, turned out much different scores. It simply doesn't seem capable of saturating these SSD's as these scores and throughput measurements are not much different than my dual drive array achieved. Not surprisingly, perceived real world performance hasn't really changed. The dual drive array was already blindingly fast. Now it's just silly. The biggest benefit is actually the added space. Using the Icydock enclosures makes install a breeze as you can see from the photos. The Mac Pro internals really are a work of art!
