SAMSUNG MZ-QL27T600 7.68 TB enterprise SSD

SKU CH-E41E-Q510Q MPN MZ-QL27T600

2.5-inch U.2 NVMe drive with 7.68 TB capacity, 6700 MB/s read and 4000 MB/s write speeds, 14016 TB TBW endurance and 256-bit AES encryption

  • 68 TB capacity stores massive enterprise datasets
  • PCIe NVMe 4.0 x4 interface delivers 6700 MB/s read throughput
  • 4000 MB/s write speed sustains heavy write workloads
  • 1100000 IOPS random 4 KB read handles intense transactional I/O
  • 14016 TBW endurance rating supports long-service deployments

Capacity and role

This Samsung PM9A3 solid-state drive delivers 7.68 TB of storage in a 2.5-inch U.2 form factor. It targets enterprise servers and storage arrays that require high-capacity flash for read-intensive workloads. The drive uses a PCI Express NVMe 4.0 x4 interface and includes 256-bit AES hardware encryption for data at rest.

Interface ceiling

The PCIe 4.0 x4 link caps sequential throughput at the stated 6700 MB/s read and 4000 MB/s write rates. Random 4 KB read performance reaches 1100000 IOPS under optimal queue depth. Sustained speeds will fall below these peaks once the controller reaches thermal limits or the host queue is not saturated.

Endurance gate

The 14016 TB total bytes written rating defines the write budget for the warranty period. Workloads that exceed this cumulative write volume will exhaust the endurance reserve before the service term ends. Buyers who need a higher write budget or a different physical connector must select another model.

Questions about this item

How do I decide which capacity of the PM9A3 to order?

The model MZ-QL27T600 is a single 7.68 TB capacity, so there is no capacity choice within this part number.

What does the 6700 MB/s maximum read rate mean once the drive is installed in a server?

It is the peak sequential read speed the controller can deliver over the PCI Express NVMe 4.0 x4 link under ideal workload conditions.

What interface standard does the U.2 connector use and what throughput does it cap at?

The U.2 connector runs PCI Express NVMe 4.0 x4, which limits the drive to the 6700 MB/s read and 4000 MB/s write ceilings stated in the specification.
