Storage is expensive, slow, and eats up a great deal of power, according to famed writer Mark Stephens, more commonly known by his pen name, Bob X. Cringely. He believes a new start-up company he’s behind can change this.
Cringely labels the new hard drive technology ‘Metal Foil Drive’ (MFD) and it consists of using flexible titanium or stainless steel foil platters in place of the much thicker and rigid glass or aluminium substrate platters in present hard drives.
Claiming that the foil drive is faster than even that of present flash memory, he beams that an MFD-equipped “… 10-gigabyte 0.85-inch drive can spin up, read or write data, then shut down again, all in less time than it takes to perform the same task using flash while being just as resistant to shock damage and more resistant to heat.”
“That 10-gig drive will cost $24 compared to $240 for 10 gigs of flash,” he adds.
He was sure to send a hearty message to the upcoming hybrid drives that Vista will support. These use both platters and flash memory to increase the access time.
“The hybrid drive is dead,” Cringely recently declared to an audience at the University of Illinois. “This uses less power than the hybrid drive and it’s faster.”
MFD is also cheaper, he says, as hybrid drives “… cost more — a LOT more — just like Vista costs more than XP.”
In equal amounts and compared with existing platters the new required materials do cost more. Cringely assures, however, that “… the total material cost is substantially less,” as the platters consist of one-tenth the mass.
The foil material is treated with the same magnetic coating of present platters, but there is a big difference in manufacturing. Rather than individually coating and polishing each platter as is currently the practise, the MFD surface can be cheaply coated and treated while rolled out on sheets. From here, platters are simply punched-out.
As a result of thinner platters, Cringely claims MFD can greatly increase storage density. “The way we obtain greater storage density is simply by putting more platters in a drive (say 12-15 instead of 4-5 in an enterprise 3.5-inch drive) because they are much thinner and can be stacked closer together.”
Cringely suggests that 60GB iPods could now be reduced to the thickness of the thinner 30GB units.
In terms of power consumption, he says hard drives based on MFD use “… 70-95 percent less energy to run than the current state of the art.” He further adds “Our 3.5-inch drives can use the spindle motor from a 1-inch drive.”
These drives can run in temperatures of 100 degrees celcius. As such, spindle speeds of 30,000rpm can be made for the enthusiast crowd. Cars, which are infamously heat-prone, are also a possibility.
Tape storage is another of the many areas in which Cringely hopes to take on with foil drives, stating in his University speech that MFD will cost only three cents more per gigabyte than existing tapes at 20 cents (as opposed to 17 cents for tapes).
He cites the dramatically increased read and write speeds and lower power usage as reasons for why companies would switch from tapes over to the slightly more expensive medium.
Cringely says we should begin to see drives based on MFD technology “… under well-known brand names” as soon as this time next year, which suggests that production is already underway.
We aren’t aware of the manufacturers behind MFD, but Cringely mentions that Seagate hopes it dies.
Presumably, Seagate isn’t one such manufacturer.
