SAMSUNG MZ3L67T6HBLC-00AW7 PM9D3a 7.68 TB enterprise SSD

SKU CH-Q032-A53CY MPN MZ3L67T6HBLC-00AW7

Internal E3.S NVMe SSD with 7.68 TB capacity, PCIe 5.0 x4 interface, 2000000 IOPS random read and 400000 IOPS random write for read-intensive server workloads

  • 68 TB capacity supports large enterprise workloads
  • PCIe 5.0 x4 NVMe interface delivers high throughput
  • 2 000 000 random read IOPS accelerates data access
  • 400 000 random write IOPS sustains write performance
  • E3.S form factor fits dense server deployments

High-capacity E3.S enterprise SSD

The Samsung PM9D3a MZ3L67T6HBLC-00AW7 is a 7.68 TB internal solid-state drive built for server deployment. It uses the E3.S form factor and connects through a PCI Express NVMe 5.0 x4 interface. The drive is rated for read-intensive workloads with 1 DWPD endurance.

Read-intensive server workloads

This SSD suits environments that demand sustained random read performance, delivering 2000000 IOPS at 4 KB. Write-heavy applications requiring higher endurance than 1 DWPD should consider alternatives. The E3.S form factor also requires compatible server chassis and backplane support.

PCI Express NVMe 5.0 x4 interface

The drive operates on a PCIe 5.0 x4 link, which determines both throughput ceiling and host compatibility. Systems limited to earlier PCIe generations will not reach the rated 2000000 IOPS random read or 400000 IOPS random write figures.

Highlights

  • 68 TB capacity supports large enterprise workloads
  • PCIe 5.0 x4 NVMe interface delivers high throughput
  • 2 000 000 random read IOPS accelerates data access
  • 400 000 random write IOPS sustains write performance
  • E3.S form factor fits dense server deployments

Questions about this item

What E3.S slot height and PCIe generation does the PM9D3a need to mount in a server?

The drive uses the E3.S form factor and requires a PCI Express NVMe 5.0 x4 interface, so the server backplane must accept an E3.S module wired for PCIe 5.0.

What is the correct insertion method for the E3.S connector, and what mistake damages the drive?

Align the notch on the E3.S edge connector with the key in the slot, press straight in until the latch clicks, and secure the retention screw; forcing it at an angle bends the PCIe 5.0 pins.

When should the 7.68 TB drive be replaced based on its write endurance rating?

The drive is rated for 1 DWPD, meaning 7.68 TB of writes per day; plan replacement once the SMART media‑wear indicator approaches the rated endurance limit.
