According to both ALF and Palomax people, OMTI controllers are one of the better ones in terms of performance vs price. OMTI RLL controller with Palomax can get about 250K/sec and 500K/sec with OMTI MFM performance vs 100K/sec read speed over a equivalent Western Digital... The OMTI controller 5527 (RLL drive) can do 1:1 interleave on a XT and it is about $100 Canadian ($80 U.S.) which is not much more of what Western Digital ask for a controller that can only handle 3:1 interleave. In another word, lower end Western Digital HDC is a dog. (Won't say the same for their higher end stuff as I have never played around with them.) > >-ethan K. C. Lee
