Why storage decides VPS performance
Even with enough CPU and RAM, slow storage ruins response times. Databases, carts, WordPress and log-heavy workloads map disk latency straight into TTFB. KuzeyDC VPS plans use 100% NVMe SSD to target far lower latency than SATA SSD or HDD.
NVMe vs SATA SSD vs HDD
- HDD: high latency, weak random I/O
- SATA SSD: solid random reads; limited by SATA
- NVMe: high IOPS and low latency over PCIe
What to measure
- Random 4K read/write (IOPS) for databases
- Average and p99 latency (ms)
- Sequential MB/s for backups and large transfers
Run a short fio-style benchmark and keep your own numbers—not marketing IOPS. On a quiet VPS plan without noisy neighbors, results stay consistent. Use the same test set when comparing cloud servers so the choice is fair.
Bottom line: do not buy a VPS on vCPU count alone; measurable NVMe I/O shapes real user experience.
