Samsung’s highest performing SAS enterprise SSD to boost server storage performance

28 April 2021

The industry’s highest performing 24 G serial attached small computer system interface (SAS) solid state drive (SSD) has been unveiled by Samsung. Based on the latest SAS interface, the new SAS-4 PM1653 drive can support twice the speed of the previous 12G SAS-3 generation.

The PM1653 is also the industry’s first 24G SAS SSD made with sixth-generation (1xx-layer) vertical-NAND chips, enabling storage capacities from 800 GB to 30.72 TB for advanced enterprise server systems.

To build a robust 24 G SAS ecosystem across the enterprise market, host bus adapter (HBA) system readiness is also essential. Samsung has been closely working with Broadcom, a leading HBA provider, to ensure a seamless and timely transition to this new SAS milestone.

Its sequential read speed can reach 4,300 MB/s, which is the maximum available speed for the 24 G SAS interface and twice the speed of the previous-generation PM1643a drive.

Leveraging its dual-port system, the new SSD will give enterprise server original equipment manufacturers the flexibility of using one or both ports depending on their system environment. Even if one port was to experience a failure during operation, data can be transferred and accessed through the other port with superior enterprise-grade reliability. The PM1653 is capable of supporting 24 G and the legacy 12G SAS-3 platform as well.

Samsung has begun sampling the PM1653 SSD with select customers, and plans to begin mass production in the second half of this year.
