Liteon make a very fast CD-Drive?
 
I just got this Combo drive (DVD-ROM - CD-RW) off my dad, and the speeds are as follows:

52X CD Read
32X CD-RW Write
52X CD Write
16X DVD-ROM Read

I did a "buffer" test on it, since it has a 2mb buffer, came back at 22MB/S and I was like :shocked: . Fastest drive I have ever seen or used before, any one else got a drive this fast? :D

Yes - I think some of our sony drives at work are 52 read & write.

lots of cd rom makers hate the companies that keep making them faster and faster - just stop its getting silly :) having the same race with dvds now but hopefully max speed will be 16x

Why?

i think they need to change the dvds if you go faster the 16X disc will spin at about the same 10,000-RPM speed as a 52X CD-ROM

As long as it works - what difference does it make?

Just as long as the discs are strong enough I mean.

cos they will probably cost more

Why faster than 16X? It reads a DVD much faster than a normal CD. Normal CD's on this are read at about 7mb/s according to the box, and DVD's are read at 21mb/s. So why go any higher than 16x? They need to make normal CD's faster unless they all start to write CD's as DVD which I bet will happen some time in the future.

It's like everything tho - new technology is always expensive - all you have to do is sit and wait and it'll probably be really cheap in the long run. Just because it's gonna cost more initially - is that a reson to not want it to be developed?

"The 16X DVD+R specification was sent to manufacturers at the beginning of June, officials said Monday. When 16X DVD burners begin shipping, the DVD+R and DVD-R camps will have topped out on the obvious means to improve optical storage performance: CD and DVD read, write, and rewrite speeds.

"16X speeds are at pretty much the physical limit," said Greg Standiford, a product engineer within the optical devices division at Hewlett-Packard, who said the limiting factor is the polycarbonate material used to form the disc: spinning it faster may crack it, he said.

"My understanding is also that when 16X comes out in the future it's as fast as we can go," added Scott LeFevre, product general manager for branded products at Iomega Corp.

Manufacturers may be able to tweak the rewrite speeds to improve them slightly and charge higher prices, LeFevre said. "But when 16X CD-RWs were announced a couple people announced 56X (CD-ROM read) speeds and the rest of us rolled our eyes and said 'Give us a break,'" LeFevre added. "

getting faster and faster isnt always great when what you have is fine - leave that for the next format

I wonder if they could make removerble hard drive platers ;)

In a plastic casing, slot it in, spins up at about 7200RPM, and runs much faster than any CD-Drive, could be the new way of transfering data :)

Explosive fracture! - it happens an 52x drives, if the CD is already sufferring from stress fractures.

Once the physical rotation limit is an issue, the fastest possible speed is then 100% full CAV from start to finish - CD-RW drives have already arrived there, but most DVDR drives are still doing Zone-CLV - even on CD-R media (a few do P-CAV, and a rare one actually added P-CAV for DVD - with the transfer rate ramping steadily from 4x to 8x at the start) - mind you, at the beginning of P-CAV mode for CD-R , there was the difficulty in maintaining good calibration over a varying speed, an issue whaich has not yet been worked on much in DVD.
