960GB U.2 enterprise SSD

The Samsung PM9A3 is a 960GB enterprise solid-state drive in a 2.5-inch U.2 form factor. It uses V-NAND TLC memory with a Samsung Elpis controller and low-power SDRAM cache. Designed for servers and storage arrays that need consistent throughput and 1 DWPD endurance. New condition.

PCIe 4.0 x4 NVMe 1.4 interface limits

The drive connects through a PCIe 4.0 x4 link using NVMe 1.4. Maximum sequential read reaches 6500 MBps while sequential write tops out at 1500 MBps. Random 4KB read performance is rated at 580,000 IOPS and random write at 70,000 IOPS. These figures are bound by the four-lane PCIe 4.0 interface.

1 DWPD endurance decides fit

The drive is warranted for 1 drive write per day, equating to 1,752 TBW over its lifetime. MTBF is rated at 2,000,000 hours. Active power draw is 9.5W for reads and 8.0W for writes with 3.5W idle. Buyers who need higher write endurance or multiple drive writes per day should look elsewhere.

Questions about this item

What capacity does the PM9A3 MZ-QL296000 provide?

The drive provides 960GB of usable storage in a single 2.5" U.2 form factor.

How does the 6500 MBps sequential read translate to real workloads?

Large-file reads such as backup streams or video ingest can approach 6500 MBps when the host PCIe 4.0 x4 link is saturated.

What does the PCIe 4.0 x4 NVMe 1.4 interface cap in practice?

The x4 lane width limits peak throughput to the PCIe 4.0 x4 maximum, so sequential reads top out at 6500 MBps and writes at 1500 MBps.
