Micron 9550 MAX 25.6 TB enterprise SSD U.2 15mm PCIe NVMe 5.0 x2
25.6 TB enterprise NVMe SSD with 14000 MB/s reads, 10000 MB/s writes and 3 DWPD endurance in a U.2 15mm form factor
- Massive 25.6 TB capacity stores vast datasets
- Sequential read up to 14000 MB/s accelerates data access
- Sequential write up to 10000 MB/s speeds heavy workloads
- 3 DWPD endurance with 228.2-year MTBF ensures reliability
- PCIe 5.0 x2 NVMe and U.2 15mm form factor fit servers
Capacity and purpose
The Micron 9550 MAX is a 25.6 TB enterprise solid-state drive built for servers, workstations and data centres that need very high storage density in a single U.2 15 mm bay. It is not for buyers who require a smaller or lower-cost drive.
Interface and speed
The PCIe NVMe 5.0 x2 connection delivers up to 14 000 MB/s sequential read and 10 000 MB/s sequential write, with 2 800 000 random read IOPS and 700 000 random write IOPS. These figures apply only to workloads that can saturate the x2 link; lighter tasks will not reach them.
Endurance rating
A 3 drive-writes-per-day endurance rating and 228.2-year MTBF define the write-life envelope for sustained mixed workloads in always-on environments. Buyers needing higher DWPD must select a different model.

Questions about this item
How often will the 25.60 TB Micron 9550 MAX need replacement given its 3 DWPD endurance rating?
At 3 DWPD the drive can sustain three full 25.60 TB writes per day for the warranty period; typical mixed read/write workloads in a server will reach that limit much more slowly, so replacement timing depends on your actual write volume.
What is the first limit that appears when the drive runs sustained writes at 10000 MB/s?
The write throughput ceiling of 10000 MB/s is the first hard limit; once the workload demands more sequential write bandwidth the controller will throttle to stay within that figure.
How much heat and power does the U.2 15mm drive produce when operating all day at 14000 MB/s reads?
The manufacturer highlights power and energy efficiency for maximum reliability, and the 0.6 inch U.2 15mm form factor fits standard server airflow designs to manage heat during continuous operation.
