Also note that (unless things have changed recently) the Elite will be out of form factor (about 2 inches longer than a 'standard' 5 1/4" drive. There are also several 3 1/2" drives in the works spinning faster than 3600 RPM. At least one of them has higher sustainable throughput at 16K and 32K i/o sizes than the WrenRunner II (now officially known as the Seagate 4767N). -- Dave Olson Life would be so much easier if we could just look at the source code.
