About This Product
The Silicon Power UD90 is a 500GB M.2 2280 NVMe SSD utilizing a PCIe 4.0 x4 interface. It offers improved sequential read/write speeds over PCIe 3.0 drives, making it suitable for general computing and light content creation. While faster than SATA SSDs, its performance is entry-level for PCIe 4.0, and it may not sustain peak speeds under heavy, prolonged loads compared to higher-tier PCIe 4.0 drives.
Verdict
“A solid upgrade for users moving from SATA to PCIe 4.0 for everyday tasks and light gaming.”
