Windows XP: Solid Sate Hard Drive
Solid Sate Hard Drive
by Themisive - 7/24/07 10:41 AMFor a while, I've been hearing about devices that will store data without the need for motors and moveable heads - similar to the solid state flash drives available now.
I was wondering, has anyone heard of them, and if so where could I get them?

Any computer shop should be able to sell you products from Samsung or Sandisk.

These were promised back in the 80s

I remember the promise of these drives back in the 1980s. This was before "flash" memory had been invented.
First attempts were EEPROM, but this was too slow even then. Most envisaged a box of static RAM with a backup battery attached, and like the BIOS battery, you would have to change it every year or so.
Flash memory is no good for this purpose, particularly with OSes like Windows running virtual memory files. Flash only has a limited number of read/write cycles, and then it dies. The way Windows plays fast and loose with a hard drive, a flash option wouldn't last long. Who of us knows how many thousand (million?) read/write cycles occur just calling up a jpeg onto the screen?
I have seen machines booting from a USB key strictly to DOS, or very crippled versions of Windows to protect the key from "virtual memory strikes", and they do work.
But remember, with those billions of transistors packed inside, the statistical likelihood of a failure is still not zero.
Hate to burst your bubble

Here is an explanation why laptops have the option of hard drive or Solid state drive. The flash memeory inside a laptop will read/write over the whole flash memory and not 1 part of it like a regular thumb drive this technique allow for the SSD to last a very long time. In 2008 you will see laptops tweaked with flash memory vs. today laptops have that option for a SSD which are not tweaked for Windows operating system. In short term your don't get the full beneficiary of a SSD.
Flash memeory has advanced and it's been geting cheaper. In the near future you will seem SSD replacing hard drives little by little.
Right now

Even if they were for general sale, they would be quite expensive in single units. It really wouldn't be worth buying at this point. A few years down the road, once the manufacturing technology has matured, and more companies are making such devices... Things could very well be different.
Of course some researchers have also just recently figured out the cause for the majority of HDD failures, in the form of frequent small oscillations of the platters. So, in a few years it may be that the mean time to failure for platter based drives is significantly higher. None of which does us much good now, but that's how it goes.
Don't spend your money yet. . .

Thanks all

Flashdisk
by daleisfflchamp - 7/27/07 11:36 PM In reply to: Solid Sate Hard Drive by ThemisiveFlashdisk is a solid state harddrive, only they're small in size, and small in capacity. I'm not kidding, solid state harddrive is based on flashdisk, only they figure out to make a bigger flashdisk that is designed to handle tens or hundreds of gigabytes of data, and not only a few gigabytes of data, and is not designed to be portable.
16 Gig is a good starting point
by TreknologyNet - 9/11/07 6:19 AM In reply to: Flashdisk by daleisfflchampI can buy a 16GB flash drive already, and I can make it bootable, appreciate the limited power it uses, enjoy its crash-proofness, and it's comparable silence BUT flash is still not immune to multiple over-write failure and an OS like windows that frequently thrashes drives "just for the hell of doing a memory swap" is going to make short order of your flash drive. The same problem would exist with Linux and the "swap partition".
