I believe it tops out at 20MB/s right now. (Don't have my manual with me right now.) To answer your questions: SCSI II is faster, and better. Generally this will only matter on hard drives, since tape units and CD-ROM drives aren't currently fast enough to really benefit from the higher throughput. You can attach a tape drive to your card without much problems. One thing to note: the sound cards are not made to be used for heavy duty use; basically they're there so you can buy a SCSI CD-ROM. Hooking up 7 SCSI devices to a SB16-SCSI2 is asking for problems. If you are looking at eventually upgrading to a SCSI based system, perhaps you might want to look at buying a separate card. If a tape drive is all you are looking for, the port may be just what you want. Hope this helps, Christopher Hayashida
