I don't know why, but I have always held this facination for "SCSI" or "Small Computer System Interface"
Even before I actually knew what it did, I had this curiousity towards it. In computer tech. class we are studying the mighty SCSI interface with all of it's capabilities. One of my class-mates pointed out that SCSI is on the way out. This filled me with sadness because of my peculier love for the thing and, I don't even have one.
I've been getting a lot of my study material from the books that I have purchased and been pouring over, it's difficult to absorb so much information, but I have gathered from "Scott Mueller's, Upgrading and Repairing PCs, 15th anniversary edition" that the SCSI is mightier than I or my classmate realized.
Scott says that it can support up to 15 devices and, when you consider that most systems can support up to 4 host adapters, each with up to 15 devices, for a total of 60 and that there are even dual channel adapters that can double that figure, that's pretty impressive.
Then there's speed. The latest "Ultra 4", (Ultra 320) SCSI version supports transfer speeds of up to 320 MBps and, an even fast version is being developed, called "Ultra 5", (Ultra 640), which will transfer at 640 MBps. By comparison, parallel ATA aka IDE transfers at speeds up to 133 MBps, whereas the new serial ATA transfers at 150MBps.
My question is this. Is SCSI really on the way out or is it on the way up?
Thanks in advance, chesgems
