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

> ACB 2322B   for 10Mb/s 
> ACB 2322B-0 for 15Mb/s
> ACB 2322D   for 20Mb/s drives.

> ACB 2322B no cache
> ACB 2322B-8 8K cache
> ACB 2322B-16 16K cache

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...
