Samsung 256GB NVMe M.2 2280 PCIe Gen4 x4 Solid State Drive

Model: MZ-VL2256A | Part Number: MZVL2256HCHQ | Series: PM9A1

The Samsung PM9A1 (MZ-VL2256A) is a high-speed, client-tier NVMe solid-state drive built on Samsung’s advanced PCIe Gen4 x4 storage architecture. Serving as the official OEM twin to the highly acclaimed retail Samsung 980 PRO, this 256GB drive is powered by Samsung's proprietary Elpis controller and high-density 3D TLC V-NAND flash memory. It is engineered to deliver extreme bandwidth, hyper-responsive data access, and top-tier power efficiency for modern gaming rigs, creative workstations, and premium laptops.

• Capacity: 💾 256 GB

• Interface: ⚡ PCIe Gen4 x4 / NVMe 1.3 (Backward compatible with PCIe Gen3)

• Form Factor: 📏 M.2 2280 (Standard 80mm length)

• Controller: 🧠 Samsung In-House Elpis Controller

• NAND Flash Type: 🧠 Samsung 3D V-NAND TLC

• Sequential Read: 🏎️ Up to 6,400 MB/s

• Sequential Write: ✍️ Up to 2,700 MB/s

• Random Read/Write: 📉 Up to 500,000 / 600,000 IOPS

• Security & Safety: 🔐 AES 256-bit Encryption, Dynamic Thermal Guard

• PCIe Gen4 Performance (OEM 980 PRO): By tapping into the massive bandwidth of Gen4 infrastructure, the PM9A1 achieves blistering sequential read speeds of up to 6,400 MB/s. It leaves older PCIe Gen3 drives behind, cutting down asset load screens and system boot cycles to near-zero.

• Premium Samsung Elpis Architecture: Utilizes Samsung’s specialized controller and an integrated high-speed LPDDR4 DRAM cache pool. This guarantees rock-solid, predictable burst transfer handling even during prolonged multitasking stress.

• Dynamic Thermal Guard Protection: Integrated with intelligent throttling firmware. The drive continuously monitors its own surface temps, keeping performance optimally high while dynamically protecting the physical NAND layers from overheating in tightly packed laptop chambers.

• TurboWrite 2.0 Acceleration: Employs an aggressive, large SLC write cache allocation layer. The drive shifts files seamlessly, executing file downloads and patch updates without suffering from the deep write speed drop-offs common in unrated client drives.

• Target Systems:

  • Next-Gen Laptops & Workstations: Native storage component for premium configurations from Dell (Alienware/XPS), HP (ZBook/Omen), Lenovo (ThinkPad P-Series/Legion), and custom desktop builds.

• Ideal Workloads:

  • AAA Gaming Storage: Eliminates micro-stuttering caused by asset-streaming pipelines in open-world titles.

  • Fast OS Boot Drive: Acts as a lightning-fast host drive for Windows 10/11 or Linux, managing core system tasks with extreme Installation Note

    💡 Model Detail: This version features the model code MZ-VL2256A, which belongs to the premium MZVL2256HCHQ family tree. It uses the exact same high-speed PCIe Gen4 architecture and Elpis hardware stack as other 980 Pro variants, ensuring maximum performance across all system builds.

    ⚠️ PCIe Backward Compatibility: This drive utilizes standard PCIe Gen4 x4 lanes, but it is backward compatible with PCIe Gen3 slots. Note that if installed in a Gen3 motherboard slot, its maximum performance will cap out at roughly 3,500 MB/s due to interface bandwidth limitations.

    The Samsung PM9A1 256GB NVMe SSD delivers premium, enthusiast-class Gen4 speeds under a highly stable OEM framework, making it a powerful storage solution for high-demand setups.
