    Angry Major bummer....

    Well guys, I found a surprise this morning when I left for work: a FedEx package from M-Systems with the uDOC they promised me. For those that don't know, the uDOC is M-Systems' newest DiskOnChip product which they claim will be the fastest embedded storage solution on the market. Even faster than SanDisk's cards. It's unique in that it uses a USB interface. For those of you that are thinking, "XP can't boot from USB!!" Well, M-Systems has a custom driver for the uDOC. So as long as your mobo can boot USB 2.0 this is probably the greatest thing ever.... As long as your mobo can boot USB 2.0. Guess what? The MII (and probably all other VIA EPIA mobo's) can't boot USB 2.0, but only 1.0. Yeah, they have 2.0 support once the OS loads, but the BIOS only runs them in 1.0 which completely *****s the possibility of using USB for booting anything other than DOS!!! There are BIOS's out there that do real USB 2.0, but it's a matter of finding out which ones now. This is really ****ty because this product seems really cool. It's even smaller than a CF disk!!! So now I'm off to finding a mobo that can boot USB 2.0. I'll be emailing VIA to see if they have any plans to un***** themselves and support true USB 2.0 booting. DAMN!!!!

    That is bad news, have you got the 2GB one ?

    Why go for USB over the IDE version? I have been looking at these, and the IDE version plugs straight in to the IDE slot, see pic attached

    That's not a uDOC. According to M-Systems this will be faster than any other DOC storage they've released before. The iDOC (IDE version you're talking about) only has 5MB/s sustained read rate and 1.5MB/s sustained write rate. They claim 20MB/s read rate and 10MB/s sustained write rate for the uDOC. It is very fast on my laptop USB 2.0 connector. Way faster than the SanDisk ExtremeIII even just copying files. It's just a matter of finding a mobo with Phoenix BIOS v4 Release 6.1 which has Highspeed USB boot. The Epia's use the Award BIOS which according to Phoenix's website doesn't have highspeed booting.

    this looks pretty cool if you can get it working, looks promising for <10sec boot times, keep us updated

    SFiorito, What kind of real life sustained transfer rates have you been getting with your CF card(s)?

    I haven't really tested any of the cards with a real HD performance tool so I can't say for sure.... I've used HDTach before, but maybe Sandra is better? Anyone have recommendations for a good HD testing tool?

    Storage review does great hard drive reviews. Check out their Testing/burn in faq.

    Sandra has a flash memory speed benchmark that I've used recently. I may take a dive into the camera sites tomorrow to see what I find...

    Okay, here's an update.... according to Intel tech support all their new boards (which run AMIBIOS8) support high-speed USB booting. I've got one of their Micro-ATX boards with a CeleronD on order so hopefully it'll be here by Friday and I'll finally be able to test out the uDOC.
