    I was at my local electronics store recently, and there by the register they had some keychain usb flash drives for super cheap. It made me wonder, Why don't they scale up the size of these drives, and use them instead of mechanical ATA hard drives? It seems to me that having no moving parts would be an advantage, and they should be alot faster. Is there something in the technology that limits this? Or would it be a matter of cost?

    Just curious


    Fixin' shit that ain't broke.

    Work out the bucks per gigabyte and you have it - over here in the uk it's about 10 for a 1Gig stick and 100 for a 250gig drive - so it's about 25:1 in favour of the IDE at present.

    Also.......Flash drive's infomation is stored chemically unlike hard drives which are stored magnetically.

    Flash drives do not last long.
    The hand of time rested on the half-hour mark, and all along that old front line of the English there came a whistling and a crying. The men of the first wave climbed up the parapets, in tumult, darkness, and the presence of death, and having done with all pleasant things, advanced across No Man's Land to begin the Battle of the Somme. - Poet John Masefield.

    Do you mean they don't hold their data for long periods, and aren't as reliable? How long can they hold data?

    I was just curious. I can't wait for the day when my long-term storage in my computer uses chips instead of platters and heads...and runs at a speed closer to the system ram.

    er I'd like an explanation as to how flash drives work as well, I'm not sure 'chemically' is the most apt description - I'll have a poke around though.

    Edit: - it's no different to the old 'flash' memory is 'chemically' is incorrect.

    Google 'Flash memory wiki' it seems accurate to me.

    Flash drives use non-volotile memory, that is, their data is stored even when power is off. The faster flash drives will run at 450Mb/s.

    SATA-II hard drives run at up to 3Gb/s. They are faster. Computers can use chips to read and write data to. This is what EPROM chips are, but they dont last long and are slow. I cannot see what is wrong with Winchester drives. do you have something against magetic storage? :wink:

    Sorry Leo, Eproms do last long, they easily outlive hard drives. I have an early PC from 1978 it still functions perfectly. Eproms, lose their data only if subjected to UV light, that is why the quartz window should be covered.

    I meant flash chips such as the bios chip.

    You have a computer from 1978 ???
    How big is your house ?????????

    Incidentally, the new Windows Vista uses any attached flash drives as extra memory.

    Vista uses them as faster means of storing virtual memory. You have to tell Vista to use a specific device in the device properties from Computer.

    You can get hard-drives now with flash memory built in for this purpose. One of the Vista-standards requires this of laptops.

    No..not really. It's just right now, my hard drive is the weak link in my computer. As a computer tech, the vast majority of hardware problems I see have to do with the hard drive. I just thought.. "why not use something without moving parts?"

    Are sata-II drives available yet? sign me up!
    edit: just "froogled" sata-II ...wow thery're availiable...I thought they weren't out yet. I wonder if you have to have a sata-II controller to get 3 gb/s? I just looked at the manual of my brand new motherboard, and it says it supports speeds of 1.5 gb/s.

    If your motherboard supports speeds of 1.5gb/s then that is unfortunately all you will get. However there are other factors which are useful to know that will affect hard-disk performanche, such as buffer memory and spin speed (in RPM)

    If you want to buy a really decent quick hard drive then I would recommend Western Digital's Raptor. (150gigs, 10,000rpm, 16mb buffer)

    If you want the model code it's: Western Digital Raptor X WD1500AHFD 150GB 16MB Hard Drive.

    And here is a link to an online review: http://www.overclockers.co.uk/showpr...-073-WD&tool=3

    And yes, SATA-II has been out for quite a while now, where have you been hiding ? :wink:

    Incidentally, what are the specifications of your computer system at present?

    I just had a motherboard failure at Christmas, and I didn't have much money, so I got what I could. It's a AMD athlon 64 3800 x2. I only had the money for 512mb of ram...which really slows things down. As soon as I get some more money, that's the first thing.
    The motherboard only cost $60 US...I kinda wish I would have researched it a little more before I bought it. I guess when I'm ready for a new drive..I might just chuck this one, and get one with a sata-II controller.
    I'm familiar with the raptors...I was looking at one of the 15k rpm models..but they're a little pricey for me right now.

    Well, as with everything in life, you get what you pay for......Thats what I have to tell my wife all the time when she buys complete crap and thinks its a bargain and then wondered why afterwards it doesnt do such a great job of doing what its supposed to do, or doesnt last long. :-D
