Short answer: NVMe is a protocol that connects solid-state drives over PCIe instead of the older SATA bus. NVMe drives reach several gigabytes per second and hundreds of thousands of random operations per second, against about 550 MB/s for SATA SSDs, which makes databases, builds and busy sites noticeably faster.
NVMe vs SSD explained
SATA SSDs are limited by the SATA III interface at 6 Gbit/s, roughly 550–600 MB/s. NVMe drives use four PCIe lanes: about 3.5 GB/s on PCIe 3.0 and about 7 GB/s on PCIe 4.0, with much lower latency and deep command queues.
On a VPS you share the host's drives, so what you actually get depends on the provider's limits. The difference is clearest for random I/O: database queries, package installs, Docker builds and WordPress admin pages.
Most providers now use NVMe for their main VPS lines; plans described only as 'SSD' are often SATA. Hard-drive (HDD) plans remain useful for cheap bulk storage.

Frequently asked questions
Is NVMe worth it for a VPS?
Yes for databases, e-commerce and anything I/O-heavy; for a static site or a small bot, a SATA SSD is fine.
