SAMSUNG
A 1.92 TB enterprise NVMe U.2 SSD built for servers that need high performance and enhanced data reliability
The Samsung PM9A3 is a 1.92TB NVMe U.2 solid state drive built for servers that demand consistent performance and data integrity. Its 2.5-inch form factor fits standard enterprise drive bays and targets IT teams managing business-critical workloads.
The drive slides into a U.2 backplane or carrier using the standard 7mm z-height, so no adapters are required when the chassis supports the form factor. Problems usually appear when the backplane wiring or BIOS does not expose the PCIe 4x4 lanes the controller expects.
Confirm the server or storage array accepts a 2.5-inch U.2 NVMe device and that the backplane provides a PCIe 4x4 electrical connection. Verify the drive bay accommodates the 7mm thickness and that firmware or RAID controllers recognise the PM9A3 model.
No published specifications for this item yet.
Verify the drive appears in the server BIOS or OS as a 1.92TB NVMe device, then run a SMART health check to ensure zero reallocated sectors and normal temperature readings under load.
The drive itself ships alone; no mounting bracket, caddy, heatsink or cables are included, so obtain a compatible U.2 backplane or adapter and any required screws for your 2.5" bay.
The listed MPN MZ-QL21T900 corresponds to the single 1.92TB capacity; no other capacities or versions are associated with this part number.
