HP FX900 Pro 1TB -- InnoGrit IG5236 PCIe 4.0 NVMe SSD Review (2026)
The HP FX900 Pro 1 TB is the capacity sweet spot in HP's flagship PCIe 4.0 SSD line, delivering near-gen4-ceiling throughput on the InnoGrit IG5236 controller.
Controller & Memory
The FX900 Pro 1 TB uses the InnoGrit IG5236 8-channel PCIe 4.0 controller with 3D TLC NAND and DRAM cache. HP rates it at 7,400 MB/s reads and 6,400 MB/s writes — the read speed saturates PCIe 4.0 x4, while the write speed is marginally below the 2 TB model's 6,700 MB/s. Endurance is 600 TBW, backed by a five-year warranty. The 1 TB variant uses a single-sided PCB, maintaining thin-laptop compatibility.
The InnoGrit IG5236 is a well-established Gen4 controller found in drives from PNY, ADATA, and Patriot. It competes directly with the more widely known Phison E18 and delivers comparable real-world performance. For gamers, content creators, and PS5 owners, the FX900 Pro 1 TB provides strong Gen4 performance at competitive pricing.

FX 900 Pro Performance & Benchmarks
The 1 TB FX900 Pro delivers 7,400/6,400 MB/s sequential reads and writes with up to 1,300,000/1,100,000 read/write IOPS. The IG5236 pseudo-SLC cache handles burst writes efficiently. Under sustained workloads, temperatures are competitive with other Gen4 flagships. Gaming load times are indistinguishable from any PCIe 4.0 drive.
