I have a 8500/150 and am going to buy a CD-RW drive from APS and it has a Interface SCSI-3, 50-pin Centronics Connector. (APS website: http://www.apstech.com/prod/item.cfm?cat=2&item=428 )Will my 8500/150 connect to the drive? I know that the speed of the 8500/150 SCSI is max 5 mb/sec. Is the speed of the SCSI 3 faster than 5mb/sec. Any and all information about this matter would be WONDERFUL!! Thanks!!
Will Somebody please tell me if I can hook up the SCSI 3 to my 8500/150. Thanks!!!!

Correct me if I'm wrong, but off the top of my head SCSI 3 is capable of either 160MB/s or 360MB/s.
Pleas note, it may be 160Mb or 360Mb, I'm not sure - or I may be thinking of Ultra SCSI 160.
Or I may be totally off. However, I am positive it is faster than 5MB/s.
Will post back info l8r.

SCSI-3? I always hear that those things weren't as fast as the SCSI-2s, especially the UW SCSI-2s, and its more less dead technology...wonder where you dug up one of those things...hmmm...I guess 126 device support is nice, but how useful is it if the cable is limited to 6 feet long? or has that been changed as well for SCSI-3?

None of this matters. With the right cable, your 8500 will run the CD-RW just fine. However, it will only transfer data as fast as the controller in the Mac, meaning you may not be able to burn CDs at the maximum speed of the drive.

I beg to differ with the last poster. Yes, it will work with the appropriate cable; yes, the SCSI interface on your machine acts as a bottleneck in a general sense. However, there isn't a CD burner in existence that can't utilize SCSI-1's bandwidth without room to spare (even a 12X needs only 1.8MBps, roughly 1/3 of SCSI-1's 5MBps). Burn away!

Thank you for all the replys! I found after going through hundreds of Apple Tech Info pages that the SCSI connection is indeed faster than the burner ;-). However, I cannot find a cable that has the connectors that I need on it. I need a 25 pin male to SCSI 3, 50 pin Centronics cable. Does anybody know where I can buy one of these babies and how much it will cost me? THANKS!!!

If you can find one, it'll probably run for about US$20+. Last I heard, Adaptec makes everything...otherwise, online warehouses are your best bet...

Hi all, well i just talked to an APStech person and she said that they supply the cable that I need :-). I wish they would post that on the support sheet for the drive. I think I am going to get it, wow 12x write that means I full CD can be burned it like 6 minutes, thats crazy fast!! Thank you everybody for all your help.
