“NVMe hosting” has become a slogan in almost every offer. It is worth knowing what is behind it and when paying more for a faster disk makes sense – and when the site will be waiting on something else anyway.
How NVMe differs from SSD
Both are solid-state drives with no moving parts. The difference is how they connect to the server:
- SATA SSD uses an interface designed for spinning disks. It tops out around 550 MB/s, with a command queue that handles one job at a time.
- NVMe connects directly to the PCIe bus. Throughput is counted in gigabytes per second and the drive handles thousands of queues in parallel.
For a website the second property matters more than throughput: the number of small operations per second (IOPS) and the time of a single read. A shop’s database does not read big files – it performs thousands of small reads from different places on the disk. That is where NVMe has the biggest advantage.
When NVMe makes a difference
- Online shops with many products, filters and variants – every search and filter is a database query.
- WordPress with many plugins – some plugins query the database on every page view.
- Admin panels and reports that crunch large tables.
- Many sites on one account, when several of them read from disk at once.
- Backups and data imports – operations on many files finish sooner.
When the disk is not the problem
- A brochure site or a cached blog – finished pages are served from memory and the disk barely works.
- Slow code or heavy plugins – if PHP computes something for two seconds, a faster disk will not shorten it.
- Large images and scripts – load time in the browser depends on page weight, not the server’s disk.
- Too little memory – without enough RAM the server slows down regardless of the disk.
A good test: if the server’s time to first byte (TTFB) is low but the page still loads slowly, the problem is in the page itself – images, scripts, the number of browser requests. If TTFB grows with traffic or when filtering products, the disk and the database are good suspects.
What else to check besides the disk type
- Account limits – how much CPU, memory and how many PHP processes your site gets. A fast disk will not help an account with too few cores.
- PHP version – newer PHP versions are noticeably faster than older ones with the same code.
- Server location – for Polish users, a server in Poland means a shorter trip for every request.
- Caching – a well-configured page cache often gives more than a disk upgrade.
NVMe at Hosteam
Our hosting plans come in two variants: standard and NVMe for sites that lean harder on their database. All VPS servers run on NVMe storage. The servers stand in a data centre in Poland.
