Hard disk drives and there future?

Something I thought of the other day looking at how far we've come in Computer technology and storage capacities, replacing the floppy disk for the USB pen drive etc is how I can't understand why we still use a physical disc and mechanical means to still store PC data which at times can be at risk of being lost due to damaged disks or errors in disk sectors. Now I'm not an expert on computer hardware and only have a basic understanding of how they run but why do we not have Hard drives that use a different means of storage like on microchips or whatever it is they use on things like Ipods and whatever? I realsie that there could still be the same risk of loosing data but won't it be different types of risks and risks that are associated with having a physical disc?

Again no expert here just trying to understand?
 
What you're talking about is available. They use flash memory as the storage medium and are called solid state drives. They have a much lower access time, but the transfer rates are in the same ball park or slightly lower than mechanical hard drives. The reason they aren't in wider usage is because they can't compete with traditional hard drives on capacity or cost. For example, at Newegg, the cheapest solid state drive is 8GB and costs $219. The largest one has a capacity of 128GB and a price tag of $3265.
 
Storage size and price...

Anyone use an 80 gb or higher flash drive?

Physical hard drives are on their way out though especially in hand held devices. 32 gb storage is already available.
 
SDHC memory cards have a theoretical maximum capacity of 2 terabytes, though the association that controls the SDHC standard has placed a cap on the maximum allowable size of 32 gigabytes; CF cards. We're probably a while off actually seeing flash storage that has quite that large a capacity (I would expect largely on grounds of cost, as already noted), but it's without the bounds of possibility that such sizes will someday be available.

Of course, while it seems likely that flash memory will dominate mobile storage for a while yet, the successor to the magnetic hard-disk might very well turn out to be a thing called racetrack memory, which IBM has very recently successfully demonstrated a working example of (see here).
 
As with everything in economics, the market will eventually determine when hard drives will no longer be utilized.

Here is one for $189, it is 32GB and SATA, not IDE. This is actually big enough for your OS and a couple games. Throw 2 of them on a RAID controller and you're laughing, use a 1TB harddisk for media and backup.
 
Hard Disks are ridiculously cheap for the storage capacity they offer. The price of Flash Memory and related technologies is falling fast, but that goes for Hard Disks too. The question is when Flash will offer enough capacity at a price cheap enough to satisfy the demands of the average user. For some tasks that date was five years ago, for some it's right now, and for others it's still a hazy cloud in the distance.

Improvements are still being made to hard disk technology and performance, I believe there are a few 15k RPM SCSI drives now that can crack 125MB/sec on the outer tracks.

Something important to realize is that computers already use multiple levels of storage arranged in a hierarchy. The faster the memory, the more expensive it is, and therefore the less of it a computer has. A hard drive is simply the bottom of the pyramid; and even if you were to interpose a layer of flash memory between it and system RAM, I suspect there still would be a hard drive down there somewhere.
 
^ That happens with RAM too, I think the real problem is in having the resulting PC cost as much as the family car. ;)
 
We also cross the boundary of how much power the average PC really needs - when we all have hi-def videos filling our hard drives we will need terabytes of storage - but it will not need to be fast, the current hdd speeds are just fine, so the issue becomes reliability - which continue to improve.

As for cpu and memory performance these will continue to improve but the average user just will not need new pcs with the kind of power that is coming.

The thing that really narks be off is artificial enticements to buy new pcs and software, like flabby operating systems that demand ridiculous cpu and memory requirements just to browse the net or write a letter - I mean you Vista!!!!
 
^ If all you need to do is browse the net or write a letter then you can get by with a 300MHz Celeron and 128MB of RAM, yet I don't see many people doing that. ;)

Decoding HD video requires a reasonable amount of processing power. I think the first batch of Toshiba HD DVD players actually shipped with Pentium 4 CPUs that Intel was keen to get rid of.

Also, and I don't wish to derail this into another Vista thread, but most of the criticisms levelled against it also applied to XP at this point in its lifecycle. For your "average user" interested in writing letters and browsing the net, XP brought two things over 9x: A shiny interface, and stability. Vista offers a shiny interface too, and it should be fairly obvious that there are some sharply diminishing returns in the realm of "not crashing" that preclude Vista from offering the second improvement. XP, like Vista, was also publically crucified upon release for its absurd system requirements, those same system requirements which are now deemed to be eminently reasonable. I can understand people disliking Vista, what I don't understand is their letting XP off the hook for the same crimes. A stable version of Windows 95, supporting the latest hardware, would do 95% of what your "average user" needs from their OS.

Eh? MILLIONS of people do nothing more than that - and will continue to do so for years.

It is the interactive features which use the processing power, but remember a Pentium 4 is an old chip now - you need nothing like the power of the latest PCs to decode HD video, absolutely nothing like it.

The big difference was it offered something genuinely new - the NT 32 bit Kernel - to home users. It was worth the upgrade to join the 32 bit world and it was genuinely quite a big deal.

For business users I would tend to agree - I have worked for a couple of companies still running Win2k networks, as for their use they have little or no need to change over.

To be fair no-one is implying it is a Vista specific criticism. Microsoft could easily release an OS that ran well on all hardware released in the last couple of years, certainly as well as XP. For reasons best known to themselves (and I have seen lots of reasons punted, cartel with PC companies, lousy coding, lousy design etc) they relase an OS in Vista that does not run well on any BRAND NEW low end cheap PC and only really gets shunting on super PCs with high end graphics cards, very fast processors and about 4GB or RAM.

For a mass market OS that is plain silly - and it is worse with Vista than it was with XP. I remember XP being a dog on new PCs shipping with 128MB of RAM, but on pretty much any new processor with 256MB it ran just fine.

A stable version of Windows 95 supporting new hardware is what Windows 98SE was by and large - and I know a lot of people who still swear by it - I dont know if you have ever installed it on a new super PC but it is comically fast, especially to boot to desktop.

The point is XP has been around so long it has become a standard, and frankly from SP1 onwards has been a damn fine operating system. This might well be true of Vista on the latest PCs but this of course might change.

What really helped adoption of XP was the release of Server 2003, as Enterprises rolled out both at the same time. Vista will almost certainly have the same benefit from the eagerly anticipated Server 2008.

I haven't, but I've wanted to try it ever since I read about how Windows "minimises" open windows by simply moving them to X,Y coordinates that are off the screen. Apparently in 9x those coordinates are close enough that, with a suitably arranged modern multimonitor setup, you can actually see all the "minimised" windows piled atop each other in the corner.

Haha - I hadn't heard that - that is rather cool.
