Supermicro

Supermicro HDS-SUN0-MZQL27T6HBLAA7 7.68 TB NVMe server accessory

SKU CH-4S5N-DK7V8 MPN HDS-SUN0-MZQL27T6HBLAA7

7.68 TB U.2 NVMe drive delivers 6800 MBps read and 4000 MBps write speeds for PCIe 4.0 servers

  • 68 TB capacity supports large-scale data workloads
  • NVMe PCIe 4.0 interface delivers 6800 MBps sequential read speed
  • 4000 MBps sequential write speed accelerates write-intensive applications
  • Up to 1000000 random read IOPS handles heavy transactional loads
  • 2000000-hour MTBF rating ensures long-term reliability

Capacity and Interface

This Supermicro server accessory is a 7.68 TB NVMe solid-state drive in a U.2 form factor. It uses Samsung TLC memory and connects via a PCIe 4.0 interface for internal server deployment.

Suited for read-heavy server workloads

The drive suits applications that demand high sequential read throughput and strong random read IOPS, such as caching tiers or content delivery. It is less appropriate for workloads that require sustained heavy write endurance or higher write IOPS than the rated figures.

Headroom at rated speeds

Sequential reads reach 6800 MBps and writes reach 4000 MBps, while 4 KB random performance reaches up to 1,000,000 read IOPS and 180,000 write IOPS. The 2,000,000 hour MTBF indicates a design target for continuous operation in enterprise environments.

Questions about this item

What server interface is required for the U.2 PM9A3 NVMe PCIe 4.0 drive to operate?

The drive requires a U.2 backplane or adapter wired for NVMe PCIe 4.0 x4 lanes.

Will the PM9A3 NVMe PCIe 4.0 drive function in a system limited to PCIe 3.0?

Yes, it will operate at PCIe 3.0 x4 speeds with reduced sequential throughput.

Which benchmark figures confirm the 7.68 TB PM9A3 is performing to specification?

Sequential reads near 6800 MBps, writes near 4000 MBps, and 4 KB random reads up to 1000000 IOPS with writes up to 180000 IOPS.
