Thanks guys . Yeah the 5 Mbps write speed is a bummer but it sure can store a lot of data.
In retrospect, I should've asked for the 32GB flash voyager as I don't even like the form factor. Stupid tube is a hassle to use and the survivor labels are just plain paper stuck onto the tube and the drive and are already coming off.(Wonder if it's Made in China but my uncle threw away the packing.)
I don't know how many inches but it's about the size of a shotgun bullet(those who have seen one can relate).
It was free so no damages. $179 for my uncle I think.
