Transitioning from the Micron 2550 Series to the Micron 2650 Series

For programs affected by the Micron 2550 lifecycle transition, the Micron 2650 NVMe SSD is the current client-series qualification path. It keeps the PCIe Gen4 NVMe and single-sided M.2 design family while moving to Micron’s ninth-generation 3D NAND.

Do not treat the series name alone as proof of interchangeability. Confirm the form factor, capacity, security configuration, firmware behavior, thermal limits, host support, and the exact replacement part number before approving the change.

The full 2650 specifications are in Micron’s current 2650 product brief.

Micron 2550 and 2650 at a Glance

The maximum values below vary by capacity and test condition. Compare the exact capacities under qualification, not just the family maximum.

Feature	Micron 2550	Micron 2650
NAND	Micron 232-layer TLC	Micron G9 276-layer TLC
Form factors	M.2 2230, 2242, 2280	M.2 2230, 2242, 2280
Capacities	256GB, 512GB, 1TB	256GB, 512GB, 1TB
Interface	PCIe Gen4, NVMe 1.4	PCIe Gen4, NVMe 1.4c
Sequential read	Up to 5,000 MB/s	Up to 7,000 MB/s
Sequential write	Up to 4,000 MB/s	Up to 6,000 MB/s
Random read	Up to 550 KIOPS	Up to 1,000 KIOPS
Random write	Up to 600 KIOPS	Up to 1,000 KIOPS
Endurance	Up to 600 TBW	Up to 600 TBW
Security options	TCG Pyrite and TCG Opal configurations	TCG Pyrite and TCG Opal configurations

The performance figures are not a system-level guarantee. Host platform, workload, capacity, firmware, temperature, and power policy affect measured results.

What Changes in the 2650

Micron’s 2650 documentation identifies three practical changes for qualification:

• G9 TLC NAND with a six-plane architecture and an I/O rate up to 3,600 MT/s;
• higher maximum sequential and random performance than the 2550 family; and
• the NVMe 1.4c revision while retaining PCIe Gen4 and the same three M.2 sizes.

The 2650 remains a client SSD for PCs and notebooks. A system that needs data-center endurance, power-loss protection behavior, hot-plug serviceability, or data-center quality-of-service targets should be evaluated against a data-center SSD family instead.

Qualification Checklist

1. Match the full old and candidate MPNs, including security configuration and packaging.
2. Confirm M.2 length, component height, connector keying, and thermal solution.
3. Check BIOS, NVMe driver, management-tool, and firmware compatibility.
4. Run representative performance, power-cycle, thermal, and security tests.
5. Record the approved firmware and replacement MPN in the program’s controlled documentation.

Send us the affected 2550 part number and host platform, and our team can help identify the 2650 configuration to evaluate.
