Transcend basic. To Gump it, "Basic is as basic does." Not glamorous, but certainly speedy and reliable. A bog-standard classic form-factor with accompanying reliability. The little head caps are always disposed of immediately.
HP stubby. Little bit pricier than similar brands, but the compactness lends itself to very efficient use in car audio systems or laptop ports.
Verbatim slim. Very svelte; possibility the most emaciated drive in the USB-verse. So wonderfully thin that, in the wild, it's sure to get lost faster than a single sock in the dryer. But, typical of Verbatim drives, nice and fast.
Lexar USB 3.0. So, on the digital roundabout of life, what one loses on the side of gripworthy chunkyness, one gains with the new USB 3.0 speed. Large files zoom up and down the pipe at about 8-10 times the speed of ye olde 2.0 standard.
Verbatim stubby. The shortest I've seen and owned. Most useful for sticking permanently into a laptop's side. Truly set and forget.
Verbatim slimline. Came with an annoying protective rubber flap which begged for removal. Thin, fast, reliable. All the good stuff.
Apacer with plastic body. Separate magnetic cap (best left in a drawer, away from other electronics). Not too flashy, but plays well with car MP3 systems.
MicroSD reader and adapter. Terrifically useful for accessing phone cards on the move.
Verbatim slider. Plastic and as chunky as anything. Somewhat flimsy and prefers not to travel too much.
SanDisk Cruzer Micro. Metal. Nice and skinny. Can take the knocks.
