NVMe SSD

NVMe (Non-Volatile Memory Express) is a storage protocol designed specifically for flash memory, bypassing the latency of the older AHCI/SATA interface. Instead of 600 MB/s (SATA SSD), NVMe SSDs typically deliver 3,000–7,000 MB/s sequentially and hundreds of thousands of IOPS — decisive for databases (PostgreSQL, MariaDB), search indices (Elasticsearch, Meilisearch) and high-concurrency WordPress setups. In hosting, 'NVMe' usually means storage pools running on data-centre-grade U.2 or M.2 NVMe drives in RAID 10. Watch out: 'SSD' alone in the spec sheet often means SATA SSD or cloud block storage with throttled IOPS — look for the explicit NVMe label.
