Yup. I'm gonna do it. I'd like to do it with windows XP... but so far have had no luck.
Anyone who's tried this before will tell you "you can't make a removable drive dynamic" which is the first step to making a drive part of a RAID in windows. A buddy and I are currently working on rewriting the drivers for a Sony Microvault 2GB thumb drive, so that windows sees it as a normal magnetic hard drive, but its slow going. Anyone have any other ideas for making this work in windows?
Also, yeah, I know it's easier to do in Linux (we're trying to get it going with Kubuntu at present) but unfortunately, neither of us are all that great with Linux. We're kinda' grasping at straws (so to speak) when it comes to the actual terminal. If you know of a good guide on how to go about raiding removable drives (or any drives) in Kubuntu, please post a link to it.
Cheers!

What programming is it in?
It just seems like some kind of deep magic that governs the proper implementation hardware.

I own/operate a Technical Consulting company, and we're working on creating a more stable way to store images of our customer's computers (for backup service we provide). Solid state is more stable and reliable than magnetic storage (hard drives), so we want to raid as many solid state drives as we can to store the images.
We were editing a C based driver, and editing the .inf file that controlled the device tags that utilized the compiled C driver.
In other words, yes, deep magic.
While I see your point about solid state being more reliable, and I believe faster, isn't this painfully cost inefficient? I mean, magnetic storage price-per-gig can go well below $1, but flash memory runs at $10/gig and higher.
I mean, for the same cost as making a 1tb flash RAID, you could make a 10tb magnetic RAID, or 10 1tb RAIDs, giving you up to 10x backup. I mean, hard rives fail, but 10 drives all at the same time? It's pretty unlikely.

while you make a good point sir, It's not just about stability, its also to see if we can do it. It may cost a lot, but its kinda fun just to see what we can do with it... not to mention that the price of flash memory is plummeting. Don't you remember when 4GB drives were $150? thats a lot more than $10/gig.
And yeah, the price is falling, but I'd still be wary to use the them as a primary storage medium, at least for now.

If, on the other hand, you really want to get the USB RAID working, that won't be much help. As far as linux is concerned, Ubuntu's forums are a great place to check. Chances are someone can help you if not actually link you to a walkthrough of how to do it.

The iPod Shuffle raid was done on OSX, the OP is doing this on Windows. I would have linked to the Shuffle Raid, but all of the pictures seem to be down so it's not as interesting. Link for those interested in it anyway.
Unfortunately, already seen it and it's a different game... but thanks anyways
You're going to hit a couple of walls..
* USB speed, the bus can only transfer so much data and frankly it is nowhere near the speed of of a SCSI or SATA bus. (with lots of flash drives connected via usb you'll have severe performance problems)
* Flash drives have a limited number of writes and with RAID you're looking at above the normal for writes
* Speed of the flash drives, while in general they offer initial speed burst general speed is much lower than that of any hard drive

I've got a spare copy of Portal, if anyone wants it message me.
took the words right outta my mouth.
and again, we're doing it for stability, not as much for performance. Not to mention just to see if we can... and we did, so no worries
Well, great
So how did it turn out?
