Corsair MP600 PRO LPX 4000GB

The Corsair MP600 PRO LPX 4000GB is a high-density implementation of the Phison E18 reference design optimized for restricted-height environments. It uses the 8-channel Phison PS5018-E18 controller paired with Micron’s 176-layer 3D TLC NAND (B47R) and a dedicated DDR4 DRAM cache to fully utilize PCIe 4.0 x4 bandwidth and maintain mapping table consistency and high random I/O performance at the 4TB capacity tier. The LPX designation denotes a factory-applied low-profile thermal solution engineered for the Sony PlayStation 5 M.2 expansion slot. At this capacity the drive typically uses a double-sided component layout; the top-mounted aluminum heat spreader manages controller thermals while rear-facing NAND packages depend on ambient airflow, and the heatsink is adhered with high-strength thermal material that is difficult to remove.

Hardware Alternatives

• Seagate FireCuda 530: Shares the exact controller and NAND configuration; often noted for slightly higher endurance ratings due to firmware validation.
• Kingston KC3000 4000GB: A direct hardware clone lacking the specialized LPX heatsink.
• Sabrent Rocket 4 Plus: Another E18-based alternative that offers similar sustained write performance.
• Western Digital WD_BLACK SN850X 4000GB: A primary competitor utilizing Western Digital’s proprietary controller; it often edges out the E18 drives in random read operations and queue depth management.
• Samsung 990 PRO 4000GB: Utilizes Samsung’s in-house Pascal controller and V-NAND; competes in the same performance tier, focusing on power efficiency and random I/O throughput.
