Frequently Asked Questions
Is the 990 Pro good for gaming?
Yes, game loads are dominated by random access, and the 990 Pro is top of class.
990 Pro or WD Black SN850X?
They trade blows. The 990 Pro has a slight edge in software polish and peak sequential reads.
Do I need the heatsink version?
On a desktop with a motherboard M.2 heatsink or good airflow, the bare drive is fine.
