I have hit and miss issues with USB at times as well. I ordered a sata
external enclosure that has a fan for cooling as well.  Some external
enclosures have both sata and USB ports.  That way you can use sata when
possible. 

I ordered three USB enclosures and only one works well.  The others
either don't work at all or are very slow. 

I might add, I've read where people who make their own external drives,
buy the drive and enclosure separately then assemble it themselves, put
the drive into their computer to format with a file system and then put
it in the enclosure for normal use.  Some think it formats better hooked
directly to a sata port inside the puter than it does over USB.  I'm not
so sure myself.  In my experience, if it works well, it works well all
the way around. 

May buy me a card that has both internal and external ports later on. 
Sale maybe??
