Samsung today announced its launch of the industry’s highest performing 24G SAS (SAS-4) SSD ― the PM1653. Based on the latest SAS interface, the new Samsung drive can support twice the speed of the previous 12G SAS-3 generation. The PM1653 is industry’s first 24G SAS SSD made with sixth-generation (1xx-layer) V-NAND chips, enabling storage capacities from 800GB to 30.72TB for advanced enterprise server systems.
The Samsung PM1653 has been optimized for high-performance enterprise servers, offering the industry’s highest random read speed – a key metric for server storage performance – of up to 800K IOPS. Its sequential read speed can reach 4,300MB/s, which is the maximum available speed for the 24G SAS interface and twice the speed of the previous-generation PM1643a drive.
Leveraging its dual-port system, the new SSD will give enterprise server OEMs 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.
In order to build a robust 24G 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. Samsung has begun sampling the PM1653 SSD with select customers, and plans to begin mass production in the second half of this year.
