Sure, technical limitations do tend to go away when there is enough money at stake. In this case I don't think that's the case, though--there's not that much advantage to faster transfer speeds. That would normally only be much of an issue to the sort of people that post here--and we have better options for throwing around big piles of data anyway.

LorenPechtel How is that different from what I said? There is SOME economic incentive--the casual user. This isn't much of an answer. If the links go dead, is your answer worth much more than a comment? Just provide the links for some example. If they go dead, there are still hundreds of them on google — phuclv.

At revolutions of about metres per second, today's state-of-the-art lead-foot drives approach the speed of sound - metres per second through air at room temperature - subjecting the spinning disc to a force times that of gravity, researchers have found.

Although Stadje has no statistics that many people are being hurt, he had his first indication last week that consumers are suffering when he received an e-mail from a man who had a plastic splinter embedded in his skin, drawing blood. The fact some drive makers have introduced speed limits on their drives indicates to Stadje that there is truth in his claims. In lab tests at Atlas Copco Controls, spinning optical disks at top speeds - up to 30, revolutions per minute rpm - resulted in severe damage to the ceiling and the protective metal sleeve that encased the test spindle.

At 52x CD-ROM speeds 27,rpm disks shatter in a "rain of plastic particles", shooting out long, sharp, knife-like shrapnel at half the speed of sound: "The result was a pile of shimmering plastic chips," he says. CD and DVD mechanisms are found in many computer and consumer electronics devices in homes, cars, and offices.

Although many such devices have the slower, older mechanisms, faster drives that could cause injury will filter through over the next year as costs fall. Following the naming convention, those drives are considered 72x CD drives. CD-ROM average seek times range from milliseconds ms to as low as 80ms. In comparison, current hard drive seek times are typically around 9ms, and some are lower. This accounts for the variable data transfer rates that one finds in advertisements and specification sheets for these drives.
