Okay, so... To make a raid 60, you make a raid 6 first then stripe that. If you started with a 4 disk raid 6 array and increased your number of disks to 8 when you stripe it, I have no trouble visualizing performance and capacity advantages. However, I'm having trouble visualizing trade offs, speed or capacity differnces if you compared a 8 drive raid 6 vs an 8 drive raid 60. If you are not Nanofrog, but you did stay at a holiday inn last night, you are welcome to reply as well. Thanks!
