Frequently Asked Questions

What is the advantage of PCIe 4.0 over PCIe 3.0 for M.2 NVMe boot drives?

PCIe 4.0 x4 doubles the interface bandwidth of PCIe 3.0 x4 — from ~3.5 GB/s to ~7 GB/s sequential read. For OS boot and hypervisor storage, PCIe 4.0 reduces boot times and accelerates large VM image loads. In M.2 form factor, PCIe 4.0 ensures the interface is not the performance bottleneck for high-IOPS read-intensive V-NAND TLC SSDs.

What is NVMe 1.4 and how does it improve on NVMe 1.3?

NVMe 1.4 introduces enhanced I/O determinism, improved power management states (APST), persistent memory region support, multi-namespace sharing improvements, and enhanced error injection. For enterprise deployments, NVMe 1.4 improves latency consistency and power efficiency compared to NVMe 1.3 — relevant for hypervisor and database OS boot workloads.

Is P41538-001 interchangeable with P24188-B21 or P24886-001 M.2 22110 variants?

No — P41538-001 is M.2 2280 (80mm), while P24188-B21 and P24886-001 are M.2 22110 (110mm). Physical dimensions differ — 2280 and 22110 are not interchangeable. Confirm your server's M.2 slot length (80mm or 110mm) before ordering. P41538-001 also uses PCIe 4.0 vs. PCIe 3.0 for the 22110 variants — performance differs as well.

The HPE P41538-001 480GB NVMe PCIe 4.0 x4 V-NAND TLC M.2 2280 read-intensive SSD delivers maximum-bandwidth embedded flash storage for HPE ProLiant Gen10 Plus and Gen11. Order today — in stock at the lowest price.
