Also, a 5.25" drive does require more power than a 3.5" drive so that may cause problems if you are using a number of NuBus cards. For the true power user, there is the FWB hammer300is. This is a 3.5" drive which fits perfectly on a standard IIcx/IIci bracket. It delivers 12.5ms seek along with an average latency of 6.95ms. Sustainable transfer rate is 2.0 MB/sec. You will be hard pressed to find a 5.25" drive which can match these specifications. (Unless you have one of our hammer1000's :-) Sorry to sound so PR-ish on the net but I wanted to put to bed a few myths about 3.5" drives. -- Henry Kwan | AppleLink: D0690 FWB, Inc. | CompuServe: 71320,1034 2040 Polk St. Ste 215 | Internet: claris!wet!logic@ames.arc.nasa.gov San Francisco, CA 94109 | UUCP: {claris,hoptoad,lamc,ucsfcca}!wet!logic
