I am a Western Digital guy, because whenever I have had a failure (twice in all these years) you call, get an RMA number, and send it. Boom. Done. No questions asked.

Seagate may be equally as customer centric but I have not had any dealings with them.

I will always suggest, however, that BIAB be run from the internal drive. Just the difference in running data through the motherboard bus rather than from a USB port....
