HPE MK000400KWDUK 400GB MLC PCIe NVMe 3.0 x4 2.5-Inch SSD with SC

Key specifications

The figures below come from this listing's own record. They are the ones that decide whether a part drops into an existing system.

• Storage Capacity: 400 GB. Usable capacity as the manufacturer states it.
• Drive Interface: PCI Express NVMe. The bus the drive expects; the controller or backplane has to present the same one.
• Interface Standard: PCI Express NVMe 3.0 x4. The negotiated link standard.
• Maximum Data Transfer Rate: 8Gb/s. Peak link rate, which is not the same as sustained throughput.
• Drive Width: 2.5". Bay width, which decides whether it drops into the slot.
• Flash Memory Technology: Multi-Level Cell. The NAND type, which tracks with endurance and cost.
• Form Factor: SFF. The size or mounting class the catalogue records for this part.
• Swappable: Yes. Whether the part is designed to be changed with the system running.

Confirming fit

Memory Clearance does not publish a verified compatibility list for MK000400KWDUK. Whether a part of this type is supported is defined by the system or switch vendor's own compatibility matrix, not by the part on its own.

The dependable check is the part number. Read the installed part number from the system's management interface and compare it with the number on this listing. If you send your server model with a quote request, it is checked against this part before you order.

Common questions

Is MK000400KWDUK in stock?

Stock moves, so the quantity shown on this listing is the current figure. For a larger quantity, send the part number and how many you need and the answer comes back against that exact number. Quotes are answered weekdays 8:00 am to 5:00 pm PST.

Does this drive come with a tray?

Only if the listing name says so. Drive listings are either bare or supplied in a generation-matched hot-swap tray, and the name states which.

Can I use this to replace a failed array member?

Match the interface, the capacity, the sector format and the class of the drive already in the array. A mismatch on any of those can be rejected by the controller.

What do I send to get a price on MK000400KWDUK?

The part number, the quantity, the condition you will accept and the server model it goes into. That is enough to answer in one pass.
