Solidigm P44 Pro 1TB -- SK Hynix-Based PCIe 4.0 NVMe SSD Review (2026)
The Solidigm P44 Pro 1 TB is SK Hynix hardware under the Solidigm brand — an in-house controller, 176-layer TLC NAND, and class-leading power efficiency at Gen4 flagship speeds.
Controller & Memory
The P44 Pro is essentially the SK Hynix Platinum P41 rebranded under Solidigm, the company formed from SK Hynix's acquisition of Intel's NAND and SSD business. At 1 TB it delivers 7,000 MB/s reads and 6,500 MB/s writes with 750 TBW endurance and a five-year warranty. The single-sided PCB fits thin laptops.
The in-house SK Hynix controller provides excellent power efficiency and thermal management — the P44 Pro is consistently among the coolest-running Gen4 flagships. For gamers and content creators, it offers the same performance as the P41 with Solidigm branding and warranty. The drive is PS5-compatible when paired with a compatible heatsink.
