Biwin NV7200 1000GB

The Biwin NV7200 is a DRAM-less M.2 NVMe drive built around the Maxio MAP1602 controller and typically paired with YMTC 232-layer 3D TLC NAND. It uses Host Memory Buffer (HMB) instead of onboard DRAM, and the NAND runs at interface speeds up to 2400 MT/s. The drive is noted for power efficiency and good thermal behavior, making it suitable for laptops and restricted-airflow builds; sustained write performance depends on the size of the dynamic pseudo-SLC cache, after which speeds fall to native TLC rates.

Key Specifications

• Interface: PCIe Gen 4.0 x4, NVMe 1.4
• Sequential Read/Write: 7200 MB/s / 6200 MB/s
• Controller: Maxio MAP1602 (Arm Cortex-R5 architecture, 12nm process)
• NAND Flash: 3D TLC (typically YMTC 232-Layer)
• DRAM Cache: None (HMB supported)
• Physical Layout: Single-sided M.2 2280 PCB
• Endurance: Competitive TBW rating typical of high-density TLC

Hardware Alternatives

• Lexar NM790 1000GB: Direct clone using the identical Maxio MAP1602 controller and YMTC NAND configuration, with virtually indistinguishable performance characteristics.
• Addlink S93: Shares the same reference design and core components (Maxio MAP1602 + YMTC NAND).
• WD Black SN770 1000GB: Direct functional competitor in the DRAM-less segment; uses a proprietary SanDisk controller and targets the same efficiency-focused high-end users.
