Ultra Fast Disk Drives With No Moving Parts
saccade.com writes "Let's face it, the slowest part
of PC's today is the disk drive. Bit
Micro has come up with a nifty solution - flash memory based
disk drives available in typical
disk
form-factors. These e-disks are electrically compatible
with ATA, SCSI, etc. but run orders of magnitude faster - access
times down to 40 usec and transfer rates over 100 MB/sec. What's
the catch? Cost. Currently going for just under $1K/G, a 30G model
I recently held in my hand was worth much more than my car. However,
as flash memory prices drop, so do the price of these drives.
Within the decade the spinning hard disk may go the way
of the floppy and CRT."
Because I'm pretty sure most of us were aware of high cost flash media disks.
Are we done yet with the whole 'floppies are dead' stories? I regularly use floppies because it's easier to plop in a floppy, copy one file and pop out the floppy than it is to put in a USB drive, wait for your pc to recognize it (don't know about Macs), copy the file then have to correctly disconnect the USB drive
What about those machines which don't have USB drives or who aren't on a network? What then? Floppies will be around much longer than anyone thinks and for good reason.

Within the decade the spinning hard disk may go the way of the floppy and CRT.
You mean it'll still be the default option on most new PCs and in use by ~90% of PC users?
The reason hard disks etc are seperate devices is because they have mechanical parts that require motors etc to work. If this is going to be replaced by memory chips then why not just integrate the whole lot on the motherboard as just another plug in memory module? Why make it slower by passing it through SCSI or ATA not to mention the extra cost of including the interface electronics?
Within the decade the spinning hard disk may be capable of holding terabytes, or even petabytes, on a single platter. And it will be orders of magnitude cheaper than solid state storage as we know it. I doubt that hard drives will go the way of the dodo anytime soon.
Just as a comparison, look at how many backup solutions still use tape media (and use it very effectively and cheaply, I might add).

Sure, hard drives are slow, but that's not my main problem with them. They *are* a bottleneck, but since most applications get the hard disk access "out of the way" at the very beginning and load everything they need into RAM, I could deal with slow hard drive technology for the rest of the forseeable future, if only...
... they were reliable. Hard drives are the only PC components that have ever died on me. Actually, that's not quite true - I had a CD-rom die once, and a few fans here and there; what do all these have in common? Mechanical parts. And when it comes down to it, what do most users value most in their computers? The files on their hard drives. Spinning death traps is what they are. Spinning, clicking, grinding death traps.
I don't know much about flash memory technology or the reliability associated with it. I don't give a hoot how fast it is. If it's solid state (no moving parts) and can guarantee me it won't one day decide to utterly destroy itself, I'm sold.
