If type does not matter, why not use an SD card?
There was an article in CircuitCellar (see 
http://www.circuitcellar.com/magazine/176toc.htm "Portable FAT library 
for MCU Applications").
I bought the article ($ 1,50) and it contains a FAT filesystem interface 
towards an SD/MMC including source code.

So if this is the only reason for USB host, go for the SD card (easier 
to implement than USB).
