Thread: CD Drives

my 48x reader cos tme about 30$ including shiping from newegg.com, its a year old, so its probably cheaper than that.

haha i have a 2x SCSI burner lying around here somewhere. and a 4x2x10 i think it is

i think it was yamaha. 90% of the cd were burned were coasters haah

CD-ROM Notes
Technical Note on CD ROM Drive Speeds

Please Note - Portions Excerpted from CMP Publication,

A fast CD ROM drive is a requirement on today's systems. PC's do not sell without one, even at the entry level. Furthermore, a drive's X factor, or speed rating, is a major selling point.

The first CD-ROM drives ran at the same speed as music (or audio) CD players and provided a data transfer rate of 150 Kbytes per second. Soon after that, 2X drives came out, transferring data at 300 KBPS. So Called 8X drives were capable of 1,200 KBPS transfer rates. Up to this point drive speeds were (are) rated according to their average speed and transfer rates.

At that point discs became unbalanced from spinning too fast, and some drives would literally shake themselves apart. A physical barrier had been reached, but apparently that did not stop manufacturers from introducing 12X, 16\X and 24X and even up to the current 50+X drives. These designations, however, often referred to the peak, not the average speeds. These drives actually offer performance similar to that of the average 8X drives.

In a more "real-world" test done by copying a 31 Mbyte file from CD to hard drive, a 24 X rated CD-ROM took 15 seconds. That works out to a transfer rate of 2,066 KBPS - just under the 16 X specification of 2,200 KBPS, or 2.2 MBPS. While this is nearing hard drive territory in terms of speed, it is nowhere near the specified 24 X transfer rate of 3,600 KBPS, yet this drive sells for considerably more than the 16 X drives comparable to it's tested performance.

As speeds continue to increase, (or more appropriately, the manufacturers literature for these products show speed increases) consumers will need to keep an even closer eye on the fine print before you make a decision as to what you really need or want in your system.


From HERE --Take it as you will-I mean....my 52x can be as crap as an 8x? Well, I also have one of those £18.00 52x drives, and I suppose in truth it does say 52x MAX.

Oooh I forgot. It says 'spinning apart', so I guess thats because they are relatively small. Who knows?

I present you the limiting speed of CDs.

Well, I dont have a Dremel, but I do have a rotozip.

I guess that will do if I ever find a wish to blow a cd up

Well, for that, just throw them like a frisbee and have them hit something hard... they make quite the mess.

you should always burn at the speed your disks are rated for... that's likely the only speed the company tested them for...

i've heard that a 52x isn't that much better than a 48x, and it's not exactly worth it to get a 52x...

But its more fun at 10000 rpm!

That's about the most amusing experiment I've ever read about...Imagine doing that same thing with a material that wouldn't bust apart, and then adding blades on the side and launching them through the woods...
