Samsung PM983 960GB Enterprise NVMe U.2 SSD – MZQLB960HAJR

Description

The Samsung PM983 MZQLB960HAJR provides 960GB of enterprise-class solid-state storage in a compact 2.5-inch U.2 form factor. It is built around PCI Express Gen3 x4 and NVMe, delivering substantially lower latency and higher parallel I/O capability than traditional SATA-based enterprise SSDs.

The drive uses Samsung 3D V-NAND TLC flash memory and is designed for demanding mixed-use workloads in servers, data centers, virtualization platforms, databases, cloud infrastructure, and other enterprise applications. Samsung’s PM983 specification lists sequential performance of up to 3,000 MB/s read and 1,900 MB/s write, with random performance of up to 400K IOPS read and 40K IOPS write for the 960GB U.2 model.

The drive also provides enterprise-oriented reliability features, including a 2-million-hour MTBF, power-loss protection, and a rated endurance of approximately 1.3 drive writes per day (DWPD) for 3 years for this specific 960GB model.

Performance
Sequential Performance
Read: Up to 3,000 MB/s
Write: Up to 1,900 MB/s
Random Performance
4K Random Read: Up to 400,000 IOPS
4K Random Write: Up to 40,000 IOPS

Enterprise Reliability

The PM983 is designed for continuous enterprise operation and includes features intended for data-center environments:

Samsung 3D V-NAND TLC technology
Enterprise NVMe architecture
Power-loss protection
Approximately 2 million hours MTBF
Approximately 1.3 DWPD endurance for 3 years
256-bit AES hardware encryption
SMART support
TRIM support
Enterprise-oriented thermal and power management
Compatibility

The MZQLB960HAJR is a U.2 NVMe PCIe SSD, not a SATA SSD.

For proper operation, the host system should provide:

2.5-inch U.2 drive bay
SFF-8639 U.2 connector
PCIe Gen3 x4 NVMe support
NVMe-capable server backplane/controller
Appropriate BIOS/UEFI and firmware support

It is commonly intended for enterprise servers, storage systems, and data-center platforms supporting U.2 NVMe drives.

Important: A standard 2.5-inch SATA backplane cannot be assumed to support this SSD simply because the physical drive size is 2.5 inches. The system must specifically support U.2 PCIe/NVMe.

Typical Applications
Enterprise servers
Data-center storage
Virtualization
Database servers
Cloud computing infrastructure
Application servers
High-I/O workloads
Mixed read/write workloads
Enterprise caching and storage tiers
Software-defined storage

Important Compatibility Note

MZQLB960HAJR belongs to Samsung’s PM983 U.2 NVMe family. It should be installed in a system specifically supporting PCIe/NVMe U.2 storage. Do not list it as a SATA 6Gb/s SSD; some third-party product pages contain incorrect interface information, while Samsung’s documentation identifies the PM983 as a PCIe/NVMe drive.
