That seems a bit over the top. I see 18 TB drives available, but let's posit 20 TB drives, so you need 50 of them. I don't think you can fit 50 3.5" drives in a 1U space, even if there's no motherboard or power supply. 50+ drive storage chassis are generally 4U. I did see some 16 drive 1U servers though, so I'm pretty sure you could fit that much storage into 3U even though I also didn't see any 3U storage chassis.

This has been a thing since 2017 [1] using EDSFF. It is technically possible for 2 PB per 1U, but price and market demand doesn't seems to value these kind of density. So they are mostly used as half petabyte for now.

2.5" SSDs are AFAIK the medium for this.
