all the discs have a maximum safe speed marked on 'em. For little ones this
is usually about 12500, but 9" for example are mostly about 7000 I think,
and 12" slower than that. 's about the angular velocity of the periphery, I
assume.

's like the urban myth about 56x CD drives - it was alleged that the
periphery of the disc goes supersonic, thereby shattering it. not true. But
they might still break up due to centripetal forces. ISTR that "standard"
CD speed is 300 rpm, so a 40x one is doing 12,000 flat out.

CDs are constant linear velocity so the RPM varies on where on the
disc you are reading data. Quick google looks like the linear speed is
1.2 to 1.4 m/s or around 200 to 500rpm. It does appear that CDs can
fail at high speeds but that is because they ain't strong enough not
because of supersonic edges.

1.4 * 56 = 78.4m/s or 175mph way short of supersonic at around
750mph...

Modern data drives are not CLV though as spining a disc up and down
from 2,000 to 12,000+ RPM isn't easy. They are Constant Angular
Velocity and the drive sorts out the varying data rates depending on
what bit of the disc is being read.

quite. nowhere near. Mind, I gather they can indeed fail, which must be
quite impressive.

What are you saying about the wonderful Charlotte..... Martyn may
correct me, but last application of WARREN and CHEQUE BOOK was for her

Doesn't the "40x" refer to theoretical data rates rather than rpm?

I can't remember the figures, but the "40x" is a marketing dept. abuse
of the facts anyway.........

highly probable. I've not yet worked out which of intel and AMD are
extracting the urine about processor speeds, probably both.

Processor speed is pretty meaningless - unless you are comparing
two processors of the same design.

I wouldn't describe Charlotte as "background", nor as a "service"!
Not within right-hook range anyhow.

It wasn't directed at Charlotte - more a general stating of what I have
seen wives do after the spending of vast sums on 4WDs.
