/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. -- Regards, Peter.
