SSD Description
The Biwin NV7400 4000GB is a DRAM-less NVMe drive built around the Maxio MAP1602 controller, using Host Memory Buffer (HMB) to use a portion of system memory for address mapping. It is commonly paired with YMTC 232-layer 3D TLC NAND, allowing the drive to nearly saturate PCIe 4.0 bandwidth. The MAP1602 platform is noted for strong power efficiency and cooler operation compared with older 8-channel controllers, enabling longer sustained write performance before thermal throttling. The 4000GB variant uses a single-sided M.2 PCB for compatibility with thin laptops and consoles.
Key Specifications
- Interface: PCIe 4.0 x4, NVMe 1.4/2.0
- Sequential Read/Write: 7400 MB/s / 6500 MB/s
- Controller: Maxio MAP1602 (12nm, ARM Cortex-R5)
- NAND Configuration: 3D TLC (Typically YMTC Xtacking 3.0)
- DRAM Cache: None (HMB Architecture)
- Physical Layout: Single-sided M.2 2280
Hardware Alternatives
- Lexar NM790 4000GB: near-identical internal components and firmware logic to the NV7400
- Acer Predator GM7: features a similar reference design with comparable internal components
- Samsung 990 PRO 4000GB: competes in sequential throughput but generally outperforms the NV7400 in heavy random I/O and sustained mixed workloads
