The 16 is the one you want for a 15Mhz drive. The -8 will only run the drive at 3:1 interleave. -- Karl Denninger (karl@ddsw1.MCS.COM, <well-connected>!ddsw1!karl) Public Access Data Line: [+1 708 808-7300], Voice: [+1 708 808-7200] Macro Computer Solutions, Inc.

Well I was talking with a tech at adaptec the other day, and this is what I was informed of for what it's worth (actually about two months ago). > According to an add in a German magazine there exist three versions of > this controller: > ACB 2322B for 10Mb/s > ACB 2322B-0 for 15Mb/s > ACB 2322D for 20Mb/s drives. > > My dealer however assures me that these versions don't exist.

The ACB 2322B is rated to 10mbps and contains 8K cache (I ran a 15mbps drive on this controller!) The ACB 2322B-8 has 8K cache and is rated to 15mbps The ACB 2322B-16 has 16K cache and is rated at 15mbps (if you can find one) The ACB 2322D has 16K cache and is just a more current version of the 2322b16 controller. I didn't ask about 20mbps drives, so I can't say if this controller is cabable of this data rate. I hope this is of some help, and maybe somebody else can shed some light on the ability of the 2322D to run at 20mbps transfer rates... ------------------------------------------------------------------------------- Internet : howardl@wb3ffv.ampr.org | Howard D.
