About This Product
The Patriot P400 V4 is a 500GB M.2 NVMe PCIe Gen 4 SSD. It offers improved sequential read/write speeds over PCIe Gen 3 drives, making it suitable for general computing and light content creation. While it utilizes PCIe 4.0, its performance metrics place it in the entry-level to mid-range of Gen 4 SSDs, often surpassed by higher-tier Gen 4 drives in sustained workloads.
Verdict
“This SSD is for users needing a basic PCIe 4.0 boot drive, but better value exists.”
