Frequently Asked Questions

What is the advantage of SAS over SATA for enterprise SSDs?

SAS provides dual-port connectivity for high-availability (no single point of failure), higher sustained throughput, and longer cable lengths — making it preferred for enterprise storage arrays and SAN deployments over single-port SATA.

What is 2D NAND MLC?

2D NAND MLC (Multi-Level Cell) stores 2 bits per cell in a planar (2D) architecture. MLC offers higher endurance than TLC or QLC, making it well-suited for mixed-use enterprise workloads with balanced read/write patterns.

The Toshiba PX05SRB384Y delivers 3.84TB of SAS 12Gb/s enterprise SSD storage with 2D NAND MLC flash and dual-port SAS connectivity — a high-endurance, high-availability SSD for enterprise SAS storage arrays and mixed-use data center workloads.
