Are you looking for current technology or the whole history? Current
technology google "ATA-100", "ATA-133", "UDMA", "EIDE", "SATA", "SCSI",
"U160", "U320" and "Fibre channel" (note that's "re", not "er") and you
should after suitable fine tuning of your search find out all you wanted
to know.
"Access time" is loosely speaking the time required for the mechanical
parts of the drive to move into position to read or write whatever data
you need to read or write, while "transfer rate" is the amount of data
that can be read or written in a given amount of time.
I'm a freshman Computer Systems Technology student at a junior college
where the instructor's cancelled 7 classes in seven weeks and cuts
hour and a half lectures to twenty minutes, tops. When he doesn't
"lecture" he shows old PBS videos. I don't have previous experience
with computer hardware.
Exactly how many kinds of hard drives are there? Out of the blue he
made us do a search for three hard drives and get their access time
and transfer rates. We have not talked a single word about hard
drives let alone access time and/or transfer rates. Hardly anybody
knew what he was talking about.
He told us to look up ATA-100's and "Scuzzies." I know that means
SCSI. I just want a link or site where the difference between hard
drives and the major brand name/models could be explained, and also
exactly what access time and transfer rate mean. (I'm assuming access
time deals with the CPU, but, heck, maybe it has to do with the OS or
application files.)
