Apologies, I believe I paid $189 for the 20tb. Black friday sale at either microcenter or newegg. WD usb external, not some off brand. That was definitely not the normal price though, and the price looks a lot higher this year :/

There are still deals to be found that are closish.

Microcenter has a 24tb external for $249 right now: https://www.microcenter.com/product/679395/seagate-24tb-expa...

amazon has a 22tb for $229 right now: https://www.amazon.com/Seagate-Expansion-22TB-External-Drive...

Those and my $189 price - which is definitely higher than I originally claimed, apologies - are all around $10/tb.
