I have a USB 2.0 Buslink hard drive, and although the drive's internal speed
is faster than my internal EIDE drive (7200RPM vs 5200RPM, or thereabouts),
in action it is only about half as fast, according to my CD writing
software's data transfer tests. Although USB 2.0 is far faster than 1.1, it

PLEASE - we did this whole raid/striping, ide vs scsi thing about 3

Do we have to go through it all again?!?!

I think that's BS. Do you have numbers to substantiate that, using same
speed drives?

Do you believe a larger cache helps with large file reads and writes? For
reads it is no help, and
How about taking all this HD and CPU stuff offline!!! I, for one, am really
tired of getting deluged with all this CRAP all over again.

Quite a bit, if you run RAID 0.

It isn't necessarily a hassle, but it sure can be...which I am sure is true
of IDE RAID systems
ntly have IDE drives with lots of file cache. I
have yet to see acceptably priced SCSI disks of the size I required.

I personally don't know of any notebooks that use SCSI drives, but I would
be happy if and when they do, at least have an external SCSI port

Steve,
> 5) raid striping is less reliable than a single disk of similar size.
That is a very debatable point (the rest of what you said, sounds fine to
me). It is a MTTF (Mean Time To Failure...and do not confuse that with
MTBF) issue, and MTTF for current drives is far more than yours or I wi
Thanks for answering my query and your input and views.

Of course, but I wasn't selective. I just found the two lowest priced
drives with the same specs.
