Biwin NV7200 4000GB

SSD Description

The Biwin NV7200 4000GB is a DRAM-less NVMe SSD built around the Maxio MAP1602 quad-channel controller and uses Host Memory Buffer (HMB) to compensate for the lack of onboard DRAM. It uses YMTC 232-layer 3D TLC NAND with Xtacking 3.0, prioritizing sequential throughput and power efficiency. The MAP1602/YMTC combination yields strong power efficiency and lower operating temperatures, so the drive seldom needs aggressive active cooling; the 4000GB variant is single-sided (all components on one side) and is physically compatible with slim notebooks and consoles that cannot accommodate double-sided drives.

Key Specifications

Hardware Alternatives

• Acer GM7000 4000GB: share the exact same BOM and firmware tuning as the NV7200
• Lexar NM790 4000GB: utilizes the same Maxio MAP1602 and YMTC 232-layer NAND combination, offering nearly identical synthetic performance profiles
• Samsung 990 EVO 4000GB: competes in the high-efficiency DRAM-less segment and uses a proprietary controller capable of hybrid PCIe 4.0 x4 / PCIe 5.0 x2 operation
