Submitted by: NoClueSpeeds of various computer interfaces
Keeping track of the speeds of the various computer interfaces can be tricky,
especially when some of them are listed in Megabits per second and others in Megabytes
per second. I had put together a list a few years ago, but it was a little dated (no
ATA-100, Ultra160 or 320 SCSI, etc.). Here is the updated list in Megabytes
per second.

I hope this is helpful. 
Keep in mind that these are maximum speeds...just 'cause the pipe is that fat,
doesn't mean you're pushing that much data through it. |
