low down on ultra160

[oXide 0]

For the longest time I've thought that the max speed any harddrive can do is just 40something megs per second....this goes for all flavors of ATA and SCSI, etc...I felt that things like Ultra160 just refers to the bandwidth that that particualr interface can handle simultainiously. For example, ultra160 can handle 4 drives going at 40megs/sec at a time. But not nessesarily one drive giving info at 160meg/sec, just because drives cant do it.

Anyway, I just ordered this ultra160 drive and the specs say

 

EXTERNAL TRANSFER RATE (mbyte/sec) _______40 Sync

Low Voltage Differential(LVD) _______80/160 Sync

 

what the heck does that mean. Does that mean the the drive actually serves data at 160megs/sec, or is that just what it "connects" to the scsi bus at?

 

Thanks

another oXidious question that goes unanswered...is it safe to assume that if I cant answer technical questions, then no one else can?

Just replying to say that I don't have a clue as to the answer to the question that you asked.

The thing is .. with things such as say udma 100 ultra 160 SCSI, that's how much is transferred via the buffer. Those transfer rates you were talking about earlier downplay sustained transfer rate or in other words, actual transfer rate.
