Frequently Asked Questions

Core Technical Specifications

Q1 What is the real-world read and write speed difference between PCIe NVMe and SATA SSD storage? +
A
PCIe Gen4 NVMe drives deliver sequential read/write speeds of up to 5,000 to 7,000 MB/s, compared to SATA SSDs which are physically capped by the legacy SATA-3 bus limit of 550 to 600 MB/s—representing an approximate 10x throughput advantage.
Q2 How does random 4K IOPS performance impact heavy MySQL and PostgreSQL database workloads? +
A
Relational databases read and write data in small random 4K chunks. Enterprise NVMe storage provides 200,000+ IOPS compared to SATA SSDs capped at 50,000-90,000 IOPS, completely preventing database query lockups during peak traffic.
Q3 Why does high queue depth in NVMe eliminate disk bottlenecking during traffic surges? +
A
The NVMe interface supports 64,000 parallel command queues with 64,000 commands per queue, whereas legacy SATA AHCI supports only a single command queue of 32 commands, creating severe disk wait time (`%iowait`) on SATA during traffic spikes.
Q4 Does NVMe storage reduce website Time to First Byte (TTFB) during uncached dynamic requests? +
A
Yes. Because dynamic CMS requests require reading PHP files, template includes, and SQL records from disk, NVMe’s sub-20 microsecond latency cuts file-access overhead and directly reduces TTFB by 40% to 60%.

Deployment & Operational Inquiries

Q5 How does PCIe Gen4 NVMe compare to earlier PCIe Gen3 NVMe drives in hosting hypervisors? +
A
PCIe Gen4 doubles the raw bus bandwidth per lane compared to Gen3 (16 GT/s vs 8 GT/s), allowing virtualization hypervisors to handle heavier parallel multi-tenant read/write streams without disk channel saturation.
Q6 Can NVMe storage prevent database table locking during bulk eCommerce catalog imports? +
A
Yes. During large CSV catalog updates or inventory syncs, NVMe’s high write throughput processes transactions and commits database logs almost instantly, preventing lengthy write locks on active product tables.
Q7 Are enterprise NVMe drives protected by hardware Power Loss Protection (PLP) in data centres? +
A
Yes. Enterprise-grade datacenter NVMe solid-state drives include on-board tantalum capacitors that supply sufficient electrical energy to commit in-flight RAM cache data safely to non-volatile flash memory during sudden power interruptions.
Q8 Why do VPS backup and system snapshot restoration processes complete significantly faster on NVMe? +
A
Creating and restoring disk image snapshots involves moving tens of gigabytes of raw disk blocks; NVMe’s multi-gigabyte sequential throughput completes image transfers in 1 to 2 minutes compared to 10 to 20 minutes on SATA.
