50 WordPress sites on one 16GB VPS. Three months in: 11GB RAM, 30% CPU. Nothing was tight.
So he asked the only question left — is NVMe real, or placebo?
It's real, but only in one place: wp-admin. The frontend is cached, so the disk sits idle. The admin panel isn't — every click is PHP, MySQL and hundreds of small reads.
Someone at ~60 sites moved to an NVMe line and called it "sluggish to normal". Same cores, same RAM, only the disk changed.
Caveat: a lot of "NVMe" plans cap IOPS low enough to make the label meaningless. Ask for the number.
We run NVMe on every LightNode instance — 40+ locations, hourly billing. Test it on one client before you commit.
Which is why "NVMe" gets oversold, and still matters.
