Why use it as a flash drive as a page file? Flash drives are limited by the USB speed. Old computers probably have usb1.1 (Judging from the DDR1 statement) and that isn't enough to be worth it.
USB 2.0 isn't useable with readyboost as well imho. It's not usable to those people from third world countries as well. Cheap flash drives are very slow yah know? Won't even right 20MB/s. That isn't usable as a page file imho.

the max throughput of usb 1.1 is just 12mbps or 1.5MB/s . usb 2 increase it to 480mbps or 60MB/s but the speed of the flash drive still depend on the chip inside the flash drive itseld

and it is actually only using flashdrive as pagefile when random read/write needed because nand flash have better random speed than traditional hard disk drive

i try readyboost on 2GB ddr3 pc and there are almost no effect at all .
