Hello,

I have created a clone of my hard drive onto a compact flash card and am booting off of it. It seems that it is much slower. In general, it shouldn't be slower? Am I wrong?

Yes I will much slower, USb drives, flash cards...etc are generally not designed for that and will be slower. And yes, you're wrong.

This comes as a mild shock to me based on some of my readings on the internet. So using flash cards with Windows XP Home on them is not going to speed up my computer from my old IDE drives.

So Far, I must be wrong since that is the result. An update from Windows XP took 8 hours to complete. Well thank you for the response. Chalk this up to experience.

Your welcome. I'll be a bit more specific about why.

First off, usb drives or flash cards or thumb drives...whatever you want to call them use pretty much the same technology as SSDs do however the Nand memory in usb drives is much much cheaper, lower quality, and therefore slower. It also operates on less channels. In addition, dont forget interface...USB is extremenly slow...its theoretical limit for usb 2.0 is like 60MB per second vs SATA II which can do like 375MB as a theoretical limit so big difference there.

And finally...
Here is a USB drive 8GB...a cheap one:

Here is the cheapest 8GB SSD...and im talking dirt cheap:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

See the price difference?...thats about 3 1/2 times more expensive.

Edit:
-I dont even think that USB flash drives have any form of buffer or cache...

Painfully, I now know that my project was a complete bust from the beginning. Thanks for the information.
