Samsung PM981 256GB M.2 2280 NVMe PCIe Gen3x4 Internal SSD

The Samsung PM981 256GB M.2 2280 NVMe PCIe SSD (Model / Part Number: MZVLB256HAHQ-000H1) is a high-performance Client OEM solid-state drive built by Samsung. Designed as a ultra-fast primary storage solution for desktop systems and modern laptops, it provides rapid OS boot times, near-instant software loading, and high-speed data access—delivering speeds 5 to 6 times faster than standard SATA drives.

Leveraging a PCIe Gen3 x4 NVMe protocol alongside Samsung's proprietary Phoenix controller (S4LR020) and 64-layer 3D V-NAND flash memory, the PM981 achieves sequential read speeds up to 3,000 MB/s and sequential write speeds up to 1,300 MB/s. It features an intelligent pseudo-SLC cache system up to 25 GB for rapid sustained burst transfers, as well as random read/write speeds up to 130,000 / 310,000 IOPS for smooth multitasking.

Available from DataDive, your trusted IT hardware and component provider in Qatar, this original Samsung OEM solid-state drive incorporates hardware-based AES 256-bit encryption (Self-Encrypting Drive) to keep sensitive data protected without degrading performance, making it an ideal, secure choice for system builders and OEM laptop upgrades.
