Supermicro (Samsung) 7.68TB U.2 PM9A3 NVMe PCIe 4.0 TLC Internal Solid State Drive (HDS-SUN0-MZQL27T6HBLAA7)

The Supermicro (Samsung) PM9A3 is a 7.68TB U.2 NVMe PCIe 4.0 TLC SSD with sequential speeds up to 6,800 MB/s read and 4,000 MB/s write, suited to servers and workstations that support U.2 drives and need fast, high-capacity storage.

Recommended For

• Server and data-center operators adding high-capacity NVMe storage for read-intensive services, such as application servers and data-heavy workloads, in a compatible U.2 system.
• IT teams fitting out U.2 server bays that need up to 7.68TB per drive and PCIe 4.0 NVMe storage for server workloads.
• Server administrators who prioritize protection for data in the drive’s cache during unexpected power loss as part of a business-critical storage setup.
• Homelab and virtualization builders with a U.2 backplane or a verified U.2-to-PCIe setup who want enterprise NVMe capacity for their server or storage host.

Real-World Use Scenarios

• For a web or application server handling requests from many users, the PM9A3 can serve frequently accessed data from local NVMe storage, helping the server keep data access responsive under concurrent workloads.
• For a server running transactional SQL workloads, it can hold database files and support frequent reads and writes; StorageReview’s SQL Server testing found competitive results, though actual performance depends on the database and server configuration.
• For a shared file server, it provides a high-capacity local tier for frequently used files, so multiple users or services can access data without relying on slower disk storage for every request.
• For a virtualized server, it can store VM disks and serve virtual-machine workloads from shared high-speed storage; benchmark results vary by workload, so test the intended VM or virtual-desktop pattern before relying on consistent performance.
