Can today's PC ultize all of a 50+X CD read spec.?

[BentValve]

Just wondering if were ever going to see 100x readers or are we at the cap with the technology/media given?

I am guessing we are at overkill already with 56X drives out there..I may be wrong but if not then what speed is actually about the usable speed for a modern high end Athlon or P4 rig?

 

[Chaotic42]

The problem isn't the computer being able to handle the speeds, it's that the discs start exploding somewhere around 60x (not 100% sure on the number).

You'd need to do some kind of multi-beam thing like the old Kenwood drives.

 

[BentValve]

So the answer is yes?

Yeah, I think it was the Kenwood 72X?

100x = 15MB/sec on a CD - way below what even a modest current PC can handle, so the answer is Yes to the title question and probably NO to the question in your post! Even 1000x wouldn't be out of the question given blue laser technology - SATA is already at 150MB/sec potential thruput (and SCSI is at 320 for 64bit/66MHz PCI slots) if the drives were actually up to doing it. But when it comes to technology, it is always wise to "never say never" .
. If someone tries/perfects the Kenwood (actually by the end of their run they had become fairly reliable, but by then Kenwood's damaged reputation had done its work) approach or similar to keep the rpms down there is no reason READ speeds can't increase dramatically. It's the cheaply made media that requires the rpms to be kept reasonable. Multiple heads would probably be required and I don't think consumers would be willing to pay the price. The CD medium is pretty much obsolescent as the media density is just too low. So no one else may attempt it except maybe in the DVD or some other higher density realm...

Isn't SATA II spec'd at 1.5 GB/s?

No, 3.0 Gb(Gigabits)/sec.

PS CDs could easily go faster by using the polymer DVDs are made out of, but since that's not part of the CD spec, the drive would have to figure out the composure or just blow up most CDs

Nope..

The Zen Technology drives uses multiple laser beams to read a CD so it does not have to spin the disc so fast. The Kenwood 72X actually spins at a rate of only about 15X.

That's why I was reluctant to part with my old Kenwood drive... It was much quieter than most CD ROM and DVD drives out there.

The Zen multibeam drives never did become very popular because they do seem to have issues with certain CD-Rs and CDRW discs... And Pioneer is the only maker to make a DVD drive with the Zen technology-- And it's SCSI only.

Doesn't matter... The new Asus E616P 16x DVD with its Quietrack technology I feel is just as good.

Are you on crack or something man? I've searched high and low, Pioneer does not have a multibeam SCSI drive.

Sorry, you are right, Pioneer does not make a truex drive. I must have confused it with something else.
