Any USB cable from a computer or electronics store should be fine. I've never
had one that didn't work (including those that came with my cameras).

The "cylinders" are ferrite chokes intended to keep the cables from radiating
RF.

A quick comment about external hard drives... Several months ago I got a
standard (not SS) external hard drive with USB 3.0 interface from Seagate in
exchange for reviewing it. It simply would not work on my computer's
front-panel USB 3.0 port -- it jerked and sputtered and beeped.

Seagate told me I should connect to a USB 3.0 port wired directly to the main
board -- and that fixed. It seems that USB ports connected to the main board
with a cable cannot supply the spec'd maximum current. This should not be a
problem with your SSD drive, which has no motor.
