WD Black SN850X NVMe SSD

A gaming-focused PCIe 4.0 drive with a Game Mode that keeps frequently used data ready rather than idling the controller down. Random read performance is excellent, which is the figure that actually affects level loading. The heatsink variant fits a PlayStation 5 without modification. Sustained writes are strong for a consumer drive. It runs warmer than Samsung's equivalent. A reliable, quick choice for a gaming system or console expansion.
