Biwin Black Opal X570 PRO 4000GB

The Biwin Black Opal X570 PRO 4000GB is a high-performance enthusiast PCIe 5.0 NVMe drive built around the Phison PS5026-E26 controller and Micron 232-layer 3D TLC NAND running at a 2400 MT/s bus speed. It includes a dedicated DRAM cache (typically LPDDR4/4x) for address mapping and sustained random I/O consistency. As a Phison E26-based drive operating at maximum potential speeds, it generates significant thermal output and the controller is known to throttle aggressively when approaching 80°C; sustained heavy write workloads will require active cooling or a high-mass heatsink with substantial airflow.

Hardware Alternatives

• Crucial T700 4000GB: The most direct hardware relative, utilizing the same Controller and NAND configuration at the same 2400 MT/s bus speed.
• Corsair MP700 PRO SE 4000GB: Another direct E26 variant sharing the same performance envelope and underlying architecture.
• MSI Spatium M570 PRO: Shares the Phison/Micron topology but is often distinguished by a distinct, large-fin heatsink design.
• Samsung 990 PRO 4000GB: PCIe 4.0 drive limited to lower sequential bandwidth but notable for strong random 4K performance and power efficiency.
