SAMSUNG PM9A3 7.68TB U.2 NVMe 2.5" internal SSD
A 7.68 TB U.2 NVMe 2.5" internal SSD delivering 6700 MB/s read, 4000 MB/s write, 1100000 IOPS random read, 200000 IOPS random write and 14016 TBW endurance
- 68 TB capacity for massive data workloads
- 6700 MB/s sequential read speeds up large-file throughput
- 1 million random read IOPS accelerate transaction-heavy applications
- 14016 TBW endurance rating supports sustained write-intensive operations
- 256-bit AES hardware encryption protects data at rest
Datacentre U.2 NVMe 4.0 x4 SSD
The Samsung PM9A3 is a 2.5 inch internal solid-state drive built for datacentre workloads. It delivers 7.68 TB of storage over a U.2 interface running PCIe 4.0 x4. Sequential reads reach 6700 MB/s and writes reach 4000 MB/s. Hardware-based 256-bit AES encryption protects data at rest.
Who this suits and who should look elsewhere
This drive fits servers and storage arrays that accept a 2.5 inch U.2 bay and need high endurance for mixed read-write workloads. The 14016 TBW rating supports sustained write traffic. Buyers who need a different physical connector such as M.2 or E1.S cannot use this drive. Systems without a U.2 backplane or PCIe 4.0 support will not gain full performance.
The spec that decides fit
The U.2 PCIe 4.0 x4 interface is the single specification that determines whether this SSD can be installed and used at its rated speed. The host must provide a compatible U.2 port wired for four PCIe 4.0 lanes. Without that connection the drive will not function or will fall back to a lower speed.
