Samsung PM9A1 1 TB (MZVL21T0HCLR-00B00)

The Samsung PM9A1 is a line of high-performance solid-state drives in M.2 2280 form factor designed for the OEM segment. These drives are actively used in premium-class laptops and desktop systems. Devices in this series utilize the PCIe 4.0 x4 interface and NVMe 1.3 protocol, enabling exceptional performance characteristics under both sequential and random workloads. The drives are built around the Samsung Elpis controller and 128-layer TLC V-NAND memory, providing high storage density and stable operation even under intensive load. The lineup is available in multiple capacities: 256 GB, 512 GB, 1 TB, and 2 TB. For the 1 TB model, sequential read speeds reach up to 7,000 MB/s and write speeds up to 5,100 MB/s. Random operation IOPS reach 1,000,000 for reads and 850,000 for writes, making these SSDs suitable for systems working with large numbers of small files and demanding low-latency requirements. The drives feature LPDDR4 buffer memory and a reliable architecture with write endurance up to 600 TBW and mean time to failure of 1.5 million hours. The heatsink-free design with high energy efficiency makes these drives ideal for thin laptops while maintaining high performance. The Samsung PM9A1 is a solution for users who value consistent speeds, reliability, and proven technology from one of the leaders in NAND memory and storage controller design.
