Frequently Asked Questions

Q: What is the interface of the Intel P5801X 400GB SSD (SSDPFR1Q400GBF1)?

A: The Intel P5801X uses a PCIe 4.0 NVMe interface in the E1.S 15mm form factor. The included PCIe adapter card converts it to a standard half-height PCIe slot, and the adapter itself supports PCIe 5.0 with full backward compatibility.

Q: What read and write speeds does the Intel P5801X 400GB enterprise SSD achieve?

A: This drive achieves sequential read speeds of up to 7,000 MB/s and sequential write speeds of up to 4,800 MB/s, making it one of the fastest enterprise-class E1.S NVMe drives available for data-center-level storage workloads.

Q: What does 100 DWPD mean for the Intel P5801X SSD?

A: DWPD stands for Drive Writes Per Day. A 100 DWPD rating means the full capacity of the drive (400GB) can be completely written 100 times per day over the warranty period — confirming this SSD is purpose-built for the most write-intensive enterprise applications.

Q: Is the PCIe adapter card compatible with standard desktop and server motherboards?

A: Yes. The included adapter converts the E1.S and E3.S SSD form factor to a standard half-height PCIe slot. It supports PCIe 5.0 and is backward compatible with PCIe 4.0 and 3.0 motherboards, allowing broad compatibility across modern server and workstation platforms.
