Enterprise U.2 SSD for server workloads

The Samsung PM9A3 MZQL27T6HBLA-00A07 is a 7.68TB enterprise solid-state drive built for 2.5-inch U.2 bays. It connects through a PCIe 4.0 x4 interface using NVMe 1.4 and is designed for read-intensive applications in data-centre environments. The V-NAND TLC memory and Elpis controller target consistent performance under sustained I/O.

Sustained performance under continuous load

Sequential reads reach up to 6700 MBps while sequential writes reach up to 4000 MBps. Random 4KB reads hit 1,100,000 IOPS and random 4KB writes hit 200,000 IOPS. Endurance is rated at 1 DWPD with 14,016 TBW. Active power draws 11.0W for reads and 13.5W for writes, while idle power sits at 3.5W. The drive operates from 0°C to 70°C with 1,500G shock resistance.

PCIe 4.0 x4 NVMe 1.4 interface limits

The four-lane PCIe 4.0 connection caps theoretical throughput at the drive’s published sequential speeds. NVMe 1.4 adds namespace management and sanitize commands but does not increase the link bandwidth beyond the x4 electrical limit. Systems limited to PCIe 3.0 or x2 lanes will reduce both throughput and IOPS proportionally. 256-bit AES encryption is handled by the controller without host CPU overhead.

Questions sur cet article

How much power does the PM9A3 draw at idle and under full read/write load?

The drive uses 3.5 W at idle, 11.0 W during sequential reads and 13.5 W during sequential writes.

What host connector and protocol are required to run this 2.5" U.2 SSD?

A U.2 backplane or cable wired for PCIe 4.0 x4 with NVMe 1.4 support is needed.

Will the 7.68 TB PM9A3 work in a server that only has PCIe 3.0 U.2 bays?

Yes, it will operate at PCIe 3.0 x4 speeds while keeping its 1 DWPD endurance and 14,016 TBW rating.
