Formatting a flash drive

I am confused about which formatting format to use in setting up a new flash drive. I am reading conflicting reports about using the MS-DOS (FAT) vs Mac OS Extended (Journaled) format.

I have some old flash drives that are formatted as MS-DOS(FAT) and they seem to work fine. I read an article where it said that the Mac OS Extended (Journaled) format resulted in slower data transfer times

Any one with any recent experience/knowledge about which way is best.

Here are a couple of articles on this issue.
Formatting as Mac OS Extended Journaled allows you to use the drive for anything the Mac can do, including Versions and Time Machine. If all you want it for is use on your Mac, this seems to be the way to go. I didn't see any mention of format affecting data transfer speed.

If you need to switch between Mac and Windows, MS-DOS (FAT) (FAT32) is nearly universal between the two systems. Mac OS can read and write FAT32. ... -mac-os-x/ ... sh-drives/
