SAMSUNG PM9D3a MZWL61T9HFLT-00AW7 1.92 TB 2.5 inch PCIe 5.0 x4 internal SSD

SKU CH-SA0N-TRNCZ

1.92 TB 2.5 inch PCIe 5.0 x4 internal SSD delivering 12000 MB/s reads and 6000 MB/s writes via NVMe

  • Fast sequential reads for large datasets with 12000 MB/s throughput
  • High random read performance at 2000000 IOPS for transactional workloads
  • Sustained write throughput of 6000 MB/s for data-intensive tasks
  • Consistent random write response at 250000 IOPS for mixed workloads
  • Low-latency NVMe protocol over PCIe 5.0 x4 for responsive operation

Capacity and interface

The Samsung PM9D3a MZWL61T9HFLT-00AW7 is a 1.92 TB internal SSD built on a PCIe 5.0 x4 link with NVMe protocol. It targets enterprise servers and workstations that need high throughput for databases, virtualization or analytics workloads.

Build quality and connectors

The drive uses a 2.5 inch U.2 form factor designed for hot-swap drive bays in rackmount chassis. That connector choice means it slots directly into backplanes without adapter cables and draws power from the bay, simplifying installation and maintenance in dense storage arrays.

Upgrade path and fit

It replaces earlier PCIe 4.0 U.2 drives when sequential read speeds of 12000 MB/s and write speeds of 6000 MB/s cut batch windows or checkpoint times. The jump is worth it for applications that saturate the older link, but not for workloads limited by CPU or network bandwidth.

Highlights

  • Fast sequential reads for large datasets with 12000 MB/s throughput
  • High random read performance at 2000000 IOPS for transactional workloads
  • Sustained write throughput of 6000 MB/s for data-intensive tasks
  • Consistent random write response at 250000 IOPS for mixed workloads
  • Low-latency NVMe protocol over PCIe 5.0 x4 for responsive operation

Questions about this item

What does the PCIe 5.0 x4 interface cap in practice?

The PCIe 5.0 x4 interface supports sequential reads up to 12000 MB/s and writes up to 6000 MB/s with this drive.

What physical space does the 2.5 inch form factor need to fit?

It requires a standard 2.5 inch drive bay or mounting bracket in the chassis.

How is the NVMe drive installed and what step is often missed?

Insert the drive into the bay, connect the PCIe cable, then enable NVMe in the system BIOS so the OS can detect it.
