Enterprise U.2 SSD for NVMe servers

The Samsung PM9A3 MZQL23T8HCLS-00A07 is a 3.84TB internal solid-state drive built for enterprise workloads. It uses a PCIe Gen4 x4 NVMe U.2 interface to deliver up to 6500 MBps sequential read and 3500 MBps sequential write speeds.

Suits arrays needing high endurance and encryption

This drive fits 2.5-inch U.2 bays and supports AES-XTS 256-bit encryption with TCG Opal 2.0 management. It is not suited for systems that lack U.2 backplane support or cannot boot from NVMe devices.

1.3 DWPD endurance rating defines write life

The Samsung V6 128-layer V-NAND provides a 1.3 drive-writes-per-day rating over three years. This figure determines whether the drive meets the sustained write demands of a specific deployment.

Questions about this item

Does the Samsung PM9A3 3.84TB U.2 drive ship with a heatsink, mounting screws or cables, or must those be purchased separately?

The drive is supplied as the bare 2.5" U.2 module only; no heatsink, screws or cables are included and any required accessories must be sourced separately.

How does the 1.3 DWPD endurance rating guide the choice between this 3.84TB model and other capacities in the PM9A3 range?

The 1.3 drive writes per day rating applies across the PM9A3 line, so selecting capacity depends on total space needed rather than endurance differences between models.

What does the 6500 MBps sequential read figure mean when the SSD is installed in a live server workload?

It represents the peak throughput the controller can deliver over a PCIe Gen4 x4 link under ideal conditions; sustained real-world speeds will vary with queue depth, temperature and system configuration.
