Samsung PM9A3 3.84TB M.2 22110 PCIe 4.0 x4 (NVMe) SSD

The Samsung MZ1L23T8HBLA-00A07 is an internal solid state drive with 3.84 TB of storage that installs in an M.2 22110 slot and connects over PCIe 4.0 x4 using the NVMe protocol. It sits in the PM9A3 line, a series Samsung created for servers and other systems that demand sustained speed and rock-solid reliability.

Inside the module, V-NAND multi-level cell memory works alongside the Samsung Elpis controller to deliver sequential transfer rates up to 5,500 MB/s for reads and 2,000 MB/s for writes. Random workloads are handled with the same urgency, reaching 800,000 IOPS for 4 KB reads and 85,000 IOPS for writes, so databases, virtual machines, and media streams keep moving without stalls.

Security is addressed on the drive itself. Encryption is performed in hardware using 256-bit AES XTS and is compliant with the TCG Opal 2.0 standard, protecting data without adding CPU overhead. A mean time between failures of two million hours and an active power draw of roughly 8.2 watts help administrators balance uptime expectations with energy budgets.

The PM9A3 proves especially useful in rack servers, hyper-converged appliances, and edge devices where consistent throughput and low latency are critical. Developers building high-speed workstations or scalable storage arrays can also benefit, provided the motherboard offers the longer 22110 M.2 slot.

Before installation, confirm that the host system supports the 22110 form factor and PCIe 4.0 connectivity.
