How may I choose an external Time Machine drive?

I don't know whether this is the correct arena for such a post. If not, I hope to be directed elsewhere.

I have a MacBookPro, recently purchased. Use of an external drive saved me, because the previous MBP went south and I was able to restore to this one. I'd like to be able to maintain *two* drives, including one offsite. How to choose?

Two factors: one is, I'm using 128G, growing by, say, 4G or so per year due to prolific addition of photos. (Going to years back to 2001: conceivably some older ones could be archived off…) So I'd like advice on what size external drive is probably best. 1T, 2T, 4T?

The other factor is, I haven't a clue in the world as to what brands are best. I don't need military-grade toughness. The offsite drive will be kept in a bank safe-deposit box, and fetched occasionally for update. What brand is a good choice? Or at least, where may I find reliable reviews of brands?

A drive 3x the size of the data you are backing up is recommended for TM.

I use Mercury Elite Pro drives from OWC and never had an issue with them.

OWC Mercury Elite Pro: Production-Grade External Hard Drive

That is very helpful to know, macjack: I thank you for your prompt reply. (I've marked it helpful and may mark it solved, but please allow me the luxury of reading other responses.)

I'm an old fart, so I figure (using my calculator) I could overdo the capacity of my current 256G MBP by the time I'm 90 or so -- 30 years hence. I don't think either my MBP or a new TM drive would last that long. Machinery would fail or new tech would arise. So it sounds as if 1T might be entirely sufficient. I'll certainly look into OWC Mercury Elite Pro right after typing this.
