There are small suppliers in Hong Kong who sell refurb enterprise drives at less-exorbitant prices. I've had good luck with this over the years. I stuck with reliable, well-known models like the 4TB HGST, 16TB Seagate Exos (X16), etc.

I used to get them with a year or so of warranty remaining, though last order I got units that must have been from a bulk OEM purchase and weren't warrantied through the manufacturer.

Regardless, I've had good luck this way and failure rates have been within expectations. I started with a few different suppliers to mix inventory in case one source turned out to be a dud, then eventually consolidated on a single supplier who does a great job and has consistently delivered good drives. This method has worked for me for over a decade. Definitely easier than flying around countries, and in my case cheaper than if I'd physically gone to the US like this guy.
