Silver 2.5 inch 15mm thick NVMe SSD with label showing 12.8TB capacity

Seagate

Seagate Nytro 5550H 12.8TB 2.5" NVMe internal SSD

SKU CH-M543-DP4EH

12.8TB 2.5 inch NVMe SSD delivering 7400MB/s sequential read and 7200MB/s sequential write with 1,700,000 random read IOPS and 495,000 random write IOPS

  • Form Factor2.5"
  • Capacity12.8TB
  • 8TB capacity supports large-scale enterprise workloads
  • 7400MB/s sequential read speed accelerates data-intensive applications
  • 7200MB/s sequential write throughput handles sustained write demands
  • 3 drive writes per day endurance rating ensures long-term reliability
  • 2500000 hours MTBF indicates high operational durability

Enterprise capacity and interface

The Seagate Nytro 5550H is a 12.8TB 2.5 inch internal SSD built for enterprise servers and storage arrays. It connects through a PCIe Gen4 x4 NVMe single port and uses 3D eTLC NAND flash. The 15mm height fits standard drive bays in dense rack environments.

Sustained write endurance

The drive is rated for three drive writes per day with a total of 70,000 terabytes written over its lifetime. Sequential write speed reaches 7,200 MB/s while random write IOPS sustain at 495,000. Average write latency at queue depth one is 12 microseconds.

Suits write-heavy workloads; not for light use

This SSD targets databases, analytics and content-delivery nodes that demand consistent high endurance and low latency. Buyers who need only occasional reads or lower capacity should consider drives with a lighter endurance rating.

Questions sur cet article

What does 7400 MB/s sequential read mean in a real server?

Sustained 128 KB reads reach 7400 MB/s over PCIe Gen4 x4, so large-file scans and database loads finish in a fraction of the time of slower drives.

What does PCIe Gen4 x4 NVMe cap in practice?

The x4 lane width limits peak throughput to the Gen4 signalling rate, so the drive tops out at the quoted 7400 MB/s read and 7200 MB/s write.

What clearance does the 15 mm 2.5 inch form factor need?

The drive measures 14.9 mm high, 70.1 mm wide and 100.4 mm deep, so it fits standard 15 mm 2.5 inch bays and caddies.
