This is atypical, however DPT HBAs are *very* touchy about termination and cabling. For instance, with two identical (old) Seagate Hawks on a SmartCache III, I get 2MB/s reads from one and 500kB/s from the other. At a minimum each drive's write cache should be disabled with dptmgr, since it causes problems with DPT HBAs. Andy.
