Samsung PM9A3 3.84TB Enterprise NVMe SSD (MZQL23T8HCLS-00A07) – PCIe 4.0 x4 NVMe, Up to 6,900 MB/s, 2.5″ U.2 (7mm)

The Samsung PM9A3 3.84TB (MZQL23T8HCLS-00A07) is a 2.5″ U.2 (7mm) enterprise NVMe SSD with PCIe 4.0 x4 NVMe connectivity and up to 6,900 MB/s read and 4,100 MB/s write. It is built for servers, storage arrays and virtualized workloads where consistent latency and data protection matter.

Consistent, protected performance for servers.

Consistent Performance and Data Protection for 24/7 Workloads

Client SSDs are tuned for short bursts of activity. Under sustained server load their performance can drop sharply, and without power-loss protection a sudden outage can corrupt data still held in the drive’s cache.

The Samsung PM9A3 3.84TB is designed for continuous enterprise duty with firmware tuned for consistent latency, power-loss protection and an endurance rating suited to read-intensive (1 DWPD) workloads.

Predictable Performance Under Load

PCIe 4.0 x4 NVMe connectivity and enterprise firmware keep latency steady for databases, VMs and file services. Sequential speed reaches up to 6,900 MB/s read and 4,100 MB/s write.

Built for Data Protection

Power-loss protection capacitors flush in-flight data to flash if power is lost, protecting array integrity.

Setup Instructions

How to Install the Samsung PM9A3 3.84TB

1. Check that your server, backplane or HBA supports this interface and form factor.
2. Install the SSD in the correct drive carrier.
3. Hot-insert it into the bay (if supported) and confirm detection in the controller or iDRAC/BMC.
4. Add it to a RAID set, storage pool or cache tier and enable health monitoring.
