Samsung PM9A3 960GB Enterprise NVMe SSD
The Samsung PM9A3 is a 960GB enterprise-class solid-state drive in the M.2 form factor. It connects via a PCI-Express 4.0 x4 interface and delivers sequential reads up to 6800mbps and writes up to 4000mbps. Random read performance reaches 1,000,000 IOPS while random writes hit 180,000 IOPS. This new drive targets servers and workstations that need high-throughput, low-latency storage.
Suited for PCIe 4.0 platforms needing 960GB capacity
This drive fits systems with an M.2 slot wired for PCI-Express 4.0 x4 and workloads that benefit from its read-heavy performance profile. It is not appropriate for platforms limited to PCIe 3.0 or lower, nor for buyers who require larger capacities or higher random write endurance than 180,000 IOPS.
PCI-Express 4.0 x4 interface decides compatibility
The single specification that determines fit is the PCI-Express 4.0 x4 interface; the host must provide an M.2 slot electrically wired for four lanes of PCIe 4.0 to achieve the rated 6800mbps read and 4000mbps write speeds. Without that link width and generation the drive will fall back to lower performance.

Questions about this item
Does my motherboard need an M.2 slot with PCIe 4.0 x4 lanes for this PM9A3 drive to work?
The drive uses an M.2 form factor and a PCI-Express 4.0 x4 interface, so the board must provide an M.2 slot wired for PCIe 4.0 x4.
Will this NVMe SSD run in a PCIe 3.0 M.2 slot if I keep my current server board?
It is backward compatible with PCIe 3.0 slots, though sequential speeds will be limited to the 3.0 x4 ceiling.
How can I verify the drive is delivering its rated 6800 MB/s read and 4000 MB/s write after installation?
Run a sequential benchmark such as CrystalDiskMark or fio; sustained reads near 6800 MB/s and writes near 4000 MB/s confirm expected operation.
