Hi UnkwnTech,
You'd need a USB host adapter which used SPI/UART/I2C and you'd need to write a driver. Maybe a native code driver.
Chris
Ahhhhhh native code!!!
In all seriousness I've posted 2 questions today (both of which you've answered) do you think it'd be easier to impliment this or is there a simpler way to store large amounts of data. I'm working on a project which requires being able to write !< 16GB to disk? I'm looking to use either 16 or 32 GB SD or Flash drives.

Hi UnkwnTech,
A few options:
1. Cloud storage
2. Combo PC + Netduino application
3. Use of multiple SD cards
4. One of the non-open-source .NET MF boards might have limited support for this (i.e. commercial SD license).

I'd love to do option 1, but that would require a GSM/CDMA shield, this is an "in-the-feld" project (also leaving out option 2). #3 would be intriguing, however I'm not sure that there are enough pins on the Netduino to do 16GB+. So that seems to leave me with option 4. Time to start doing some research.

what kind of data are you storing? what kind of time period are you dealing with? Maybe a compression algorithm?
Something like this and a ND+ could get you to 8GB?

That is an interesting option, one that I hadn't considered.

I'm thinking you could stage a file on the local SD card, then FTP it to the nas device on a background thread.

here's another interesting unit on Amazon, with a 2TB limit:

That is also an interesting option. So much so that I just ordered one.

I see this device is $35.99, for $4 more you could geat a wireless router that supports 2 USB drives. See: http://www.newegg.co...ASUS-_-33320030, an ASUS WL-500GP V2 802.11b/g Multi-Functional Wireless Router with x2 USB Plug-NShare hard drive function and Print Server Function $39.99 after rebate.
I have never used either of these devices so I can not say which would work better.

I had considered that however the application for this is to be "in-the-field" and battery powered, I don't want anything larger than absolute must, and no more features than I can get away with.
