/dev/nvme0n1:
 Timing cached reads:   18158 MB in  1.99 seconds = 9124.28 MB/sec
 Timing buffered disk reads: 5262 MB in  3.00 seconds = 1753.46 MB/sec

That's a "Samsung SM951 - NVMe Native Next Gen PCIe3 x4 M.2 256GB SSD", 
quoting from the invoice issued by Armari[1], the system builder. It's four 
years old, so it isn't even the latest whiz-bang toy. The motherboard is an 
Asus X99-A.

The whole Gentoo system is on it, apart from /tmp, /var/tmp/portage and /home/
prh/boinc. Boinc runs 24/7/52 on 12 threads + Radeon GPU.

1.  Armari build high-powered workstations for the London city financial 
markets, where fractions of a second count. Some serious iron.
