Silicon Power 4TB UD90 NVMe 4.0 Gen4 PCIe M.2 SSD R/W up to 5,000/4,800 MB/s with Heatsink (SP04KGBP44UD9005AC)

Gen4 Speed. Thermal Control. Zero Compromise.

The Silicon Power UD90 4TB NVMe SSD with Heatsink takes everything that made the standard UD90 an Editor's Choice winner and adds active thermal management for sustained peak performance. With read speeds up to 5,000 MB/s and write speeds up to 4,800 MB/s, this is the version built for demanding workloads, long gaming sessions, and systems that run hot.

The included aluminum heatsink keeps thermals in check under sustained load — so you get consistent Gen4 performance without throttling, even in compact or high-airflow builds.
