Samsung PM1653 7.68 TB 2.5" SAS V-NAND
Product Information
Enterprise SAS V-NAND SSD for High-Demand Data Centre and Server Storage
The Samsung PM1653 7.68TB is an enterprise-class 2.5-inch SAS V-NAND solid-state drive built for data centre, server and high-availability storage environments. Operating over SAS 24.0 Gbps, it delivers sequential read speeds of up to 4,200 MB/s and sequential write speeds of up to 3,800 MB/s, alongside strong random IOPS performance suited to the mixed read and write workloads of enterprise storage arrays.
Designed for IT infrastructure teams, data centre architects and storage administrators specifying high-capacity, enterprise-reliability SSD storage for SAS-based server platforms, the PM1653 combines Samsung's V-NAND density with the dual-port SAS interface that enterprise environments rely on for path redundancy and continuous availability.
Key Features
SAS 24.0 Gbps Interface with Dual-Port Support
The SAS 24 Gbps interface provides higher protocol-level throughput than SATA and supports dual-port connectivity, enabling path redundancy in enterprise storage arrays and server configurations where continuous availability is a requirement.
7.68TB V-NAND Capacity
7.68TB of Samsung V-NAND SSD storage in a single 2.5-inch SFF form factor, providing high-density storage for rack-mounted servers and all-flash arrays while reducing the physical drive count compared to lower-capacity alternatives.
Enterprise-Grade Endurance and Reliability
Built to Samsung's enterprise SSD standards with high write endurance ratings, power-loss protection and end-to-end data path protection for data integrity in 24/7 server and storage environments.
Strong Sequential and Random Performance
Up to 4,200 MB/s sequential read and 3,800 MB/s sequential write, alongside high random read and write IOPS, provide the storage performance tier appropriate for database, virtualisation, backup and analytics workloads.
Power-Loss Protection
Built-in capacitor-based power-loss protection preserves data in the write buffer if power is interrupted, reducing the risk of data corruption in server environments where power events can occur.
2.5-Inch SFF Form Factor
The standard 2.5-inch Small Form Factor fits the SAS drive bays found in the major enterprise server platforms from HPE, Dell, IBM and Lenovo, providing broad deployment compatibility.
Why Choose the Samsung PM1653 7.68TB
For UK data centre teams and storage administrators specifying enterprise SAS SSD storage:
- SAS 24 Gbps and Dual-Port Redundancy – The enterprise-standard interface for server storage arrays requiring path failover and continuous availability.
- 7.68TB High Density – Maximises capacity per drive bay, reducing physical drive counts and associated failure points in large arrays.
- Enterprise Reliability Features – Power-loss protection, end-to-end data protection and high TBW endurance for 24/7 production workloads.
- Samsung V-NAND Quality – Enterprise-grade manufacturing from one of the primary NAND flash producers globally.
The appropriate storage specification for data centre projects and server storage deployments requiring high-capacity, enterprise-reliability SAS SSD with the throughput to serve demanding server workloads.
Frequently Asked Questions (FAQs)
Q: Which server platforms is the Samsung PM1653 7.68TB compatible with?
A: The PM1653 uses the standard 2.5-inch SFF SAS form factor and is compatible with enterprise server platforms from HPE (ProLiant), Dell (PowerEdge), IBM and Lenovo that provide SAS 12Gbps or 24Gbps drive bays. Confirm your server's SAS controller and backplane are compatible with 7.68TB capacity drives, as older controllers may have per-drive capacity limits.
Q: What is the advantage of SAS over SATA for enterprise storage?
A: SAS provides higher interface throughput (24 Gbps vs 6 Gbps for SATA III), dual-port path redundancy for high-availability configurations, better error detection and correction at the protocol level, and a broader feature set for enterprise storage management. For server storage arrays where continuous uptime and path failover matter, SAS is the appropriate interface.
Q: Is the PM1653 suitable for use in an all-flash array?
A: Yes. The PM1653 is designed for deployment in enterprise storage arrays and all-flash array platforms that accept 2.5-inch SAS SSDs. Confirm your array vendor's compatibility matrix for supported Samsung SSD models and firmware versions.
Q: How does the Samsung PM1653 compare to NVMe U.2 enterprise SSDs for similar workloads?
A: SAS SSDs offer dual-port redundancy which NVMe U.2 does not provide in standard configurations. NVMe U.2 typically offers higher raw throughput but requires NVMe-capable HBAs or controllers. For environments already built on SAS infrastructure, the PM1653 provides enterprise-class performance without requiring controller upgrades. For new builds prioritising maximum throughput, NVMe enterprise options such as the Memblaze PBlaze7 range should also be considered.
