Micron 2550 NVMe (PCIe 4.0 NVMe/5,500 MB/s Read/4,700 MB/s Write/Mainstream OEM-Grade Drive) Review

The Micron 2550 NVMe brings Micron's own in-house NAND manufacturing and controller engineering to a mainstream client-grade drive, originally aimed at OEM system builders but also available at retail for buyers who want Micron-branded components directly.

At up to 5,500 MB/s read and 4,700 MB/s write, this drive delivers solid mainstream PCIe 4.0 performance suited to general desktop and laptop use rather than gaming-flagship workloads. Against the Crucial P310, covered elsewhere on this site, both drives share Micron's parent-company NAND manufacturing, with Crucial's consumer branding carrying a more retail-focused warranty and support structure. Against the ADATA Legend 970, also covered elsewhere on this site, both target similar mainstream, non-flagship buyers.

Best for

Buyers who specifically want Micron-manufactured NAND and controller components in a mainstream drive. This drive offers Micron's engineering directly rather than through the consumer-facing Crucial brand.

Not for

Not for gamers seeking flagship-tier PCIe 4.0 speed. The Samsung 990 PRO or Seagate FireCuda 530, both covered elsewhere on this site, better serve that need.
