Could someone clear this up for me?

So I was sitting around and reading about new tech. I finished reading an article on samsungs flash memory progress. Naturally I wondered when they'll be on common ground. But I'm confused on several things...

How come some solid state drives such as the one mentioned in this topic Link have data access '250' times faster that standard hd tech but practically all flash memory I've seen has read/write times the same MB has your common hard drive?

Reading about that I-ram card, it appears to be limited by the Sata bandwidth. Are these solid state drives using a different interface that hasn't found it's way into household desktops?

Thanks to anyone who answer my stupid questions ...

Flash is different from Ram. Flash is non volitile ( I think) so it doesn't need electricity running through it constantly to remember things. Your regular ram that you use needs constatn voltage to remember things. If it doesn't get fed, it will forget everything. That is why Flash drives are slower than ram drives.

That's one reason why there different. But it doesn't explain why there so much slower.

Any other replies as to why flash memory is slower that those solid state drives.
