  • Dual-port SAS interface delivers sequential reads up to 2100 MB/s
  • Random read performance reaches 400K IOPS for virtualised workloads
  • V-NAND TLC technology exceeds planar MLC endurance
  • Slim 15mm height enables high-density server deployments

High-density enterprise storage

The Samsung PM1643 delivers 30.72TB of capacity in a 2.5-inch form factor designed for enterprise servers and storage arrays. It targets administrators who need to consolidate large datasets into fewer drive bays without moving to bulkier 3.5-inch mechanical drives.

SAS dual-port integration

A native SAS 3.0 controller provides a dual-port 12Gb/s interface for high-availability configurations and direct connection to compatible backplanes or RAID controllers. The 15mm height fits standard 2.5-inch drive carriers, allowing density upgrades within existing chassis without new infrastructure.

Sustained random workload headroom

Sequential reads reach 2100 MB/s while random reads hit 400K IOPS, with firmware-tuned QoS keeping virtual machines responsive under heavy utilisation. The 3D TLC V-NAND endurance suits read-intensive and mixed workloads; write-heavy or latency-critical applications may require higher-endurance alternatives.
