What you do need is a USB flash drive. I had an 4GB and an 8GB in my desk already and you may have one kicking around your office as well.
Now, there are some specifications which I will post here just in case you decide to go out and buy one, but I just tried what I had handy since many don't have read/write specification listings on the device. How much information can you put on a device the size of your thumb or smaller? ☺ The USB Flash Drive must have a capacity of at least 256 MB, with at least 64 kilobytes (KB) of free space. I recommend a larger USB flash drive and they are pretty inexpensive for a 1GB or more. It needs to be at least a 2.5 MB/sec throughput for 4-KB random reads and at least a 1.75 MB/sec throughput for 1MB random writes.

Have a bunch of flash drives you wish to dedicate? Windows will allow you up to eight flash drives for a maximum 256 gigabytes (GB) of additional memory. Of course, you would be limited by the number of USB slots you have on your computer.
