Interesting. For a BackBlaze type device with 60 drives, that's 3.6PB of raw storage. BackBlaze's site is blocked at work, but aren't they up to using 22TB drives? And I think Seagate announced 30TB spinning drives this year. So that's 1.3PB or 1.8PB with 3.5" drives. Now if you double the amount of drives (assuming those new Samsung drives are 2.5", and use the propsoed 122TB drives, and you could cool and power it) you'd have 14.4PB! Amazing since the original design needed like 15 pods for a single petabyte.

Cooling and power is less of an issue for workloads like backblaze because most of the drives in any machine will be powered off for long term backup. R2 is probably a different matter, I guess they probably have a caching layer for that.

If those drives uses 2 or 4 PCI Express lanes, wouldn't a modern CPU/mainboard have trouble connecting such many SSDs?

  Yeah, Epycs have 128 PCI-E lanes, so you can get close with 2x, but you do need some for e.g. networking. Though you can also do dual-CPU.

  Not with a PCIe switch daughterboard. These applications aren't routinely bottlenecking PCIe bandwidth.

>Interesting. For a BackBlaze type device with 60 drives, that's 3.6PB of raw storage. BlackBlaze storage pod are 4U, that is 0.9PB / 1U. We have been able to store 1PB per U since ~2020 with EDSFF. So the density achievement isn't quite new.
