My experience has been that the ASR (5400s, 2010s, etc) outperform the AAC (2200s). I don't currently have a similar ASR system setup, i'll try and get one to post an objective measure. On a 4-disk raid5 (similar disk, IBM IC35L146UCDY10-0 147GB, 10K), I'm achieving 46MB/s write, and 83MB/s on read, 'sequential' dd performance with AAC on RELENG_4. --don
