This is one of the case limited by PCIe speed, sharing it with SSD so Network could only do 5x400Gbps Network. This is on PCIe 5.0, luckily we have 7.0 spec ready and 8.0 is even in 0.5 draft status.

If we could somehow increase the density further by 5x, we would be able to store 1EB in a single rack.

The most interesting part to me is the last sentence.

>Scality tells us it’s working on supporting a future nearline-class SSD from Samsung, viewed as an HDD killer, with similar or even larger capacity and a roadmap out to a 1 PB drive.

Finally a HDD killer. May be in another 5 - 10 years time. The day of everyone having an SSD NAS / AI Cloud at home will come.

QLC already beats out HDD in power constrained hyperscalar environments. Capex is not the only factor.
