C/D750 Solid-State Drive Series

Product Highlights

  • NVMe Support
  • High and Consistent Performance
  • Proven Data Reliability
  • Hot-Pluggable
  • MemSolid2.0


SFF-8639 Supported, Front-end maintenance support

The PBlaze4 2.5’’ form factor adheres to U.2 provisions for hot plug, hot removal and hot swap. PBlaze4 Serials will guarantee the integrity of data both already committed to non-volatile NAND media and cached writes commit to media during hot plug operation.

Increased Return on Investment

Low Host Memory and Compute Overhead, Increased Density, Reduced TCO

Utilizing Memblaze’s innovative Device-based Architecture, PBlaze4 can significantly reduce host system overhead (1MB memory occupy). With the flexibility of 2.5’’ form factor, it is effective to reduce deployment time, increase the PCIe SSD density and, save operating expense for data centers and reduce the total cost of ownership (TCO).
