I think you can use two 16 gig flash drives together to get your 32g. You can store your saves, DLC and even full games on them.
The limit is 32GB per flash drive, and you can use 2 flash drives at the same time for a rough total of 64GB, it's been that way for a while now. --- http://www.forzamotorsport.net/en-US/gallery.aspx?gamertag=TheBlueStig My Forza 4 gallery, all paintjobs available for purchase on my storefront.
but I believe you have to get a $15 transfer cable to take the data off the old one and put it on the new one?
What old one?
You said he has a 4GB Slim, that means he doesn't have an HDD.
The 4GB storage device is an internal flash drive pre-configured as an MU (and which does not factor into the 2 USB storage device limit), it is not an HDD. --- R.I.P. Eve English (Feb. 12, 1968 - Oct. 13, 2010) Momma Eve, you will be missed.

You should be able to use anything that can be formatted to FAT32 and connect via usb. Read/write times might not be ideal though. --- You can't make an omelette without crushing dozens of eggs beneath your steel boot and then publicly disemboweling the chickens that laid them as a warning.
