Well, two hard drives in RAID-0 if you want to play it back in real-time without copying it first to faster storage, because a single SATA drive cannot sustain 597.2MB/sec. Unless your definition of "basic consumer external hard drive" is an NVMe SSD over 10Gbps USB 3.2 or better.

As the thread says - it’s compressed. I’m giving uncompressed sizes as an upper bound.

The GP is pointing out that storing an uncompressed film isn't useful if it can't be played back. Playing back an uncompressed 4K film is nearly 600MBps. That's a data rate you're not going to get out of any consumer HDDs.

But they're not uncompressed. They're compressed. You don't need to play them back uncompressed. You can even compress them losslessly.

I probably wouldn't call it "basic", but aside from that, https://www.amazon.com/Sabrent-Rocket-Thunderbolt-External-S... seems to fit the bill fine.
