Value Score Breakdown

Our Verdict

Professional video editors and data hoarders who need 4TB of fast NVMe in a single M.2 slot will appreciate the 990 Pro 4TB's PCIe 4.0 reads at 7,450 MB/s that sustain through large project files without throttling. At $949, it costs $349 more than the WD Black SN850X 4TB ($600, 73/100) — a drive that scores 12 points higher on value and supports PS5 heatsink compatibility. Unless Samsung's ecosystem tools are non-negotiable, the SN850X 4TB is the better buy at this capacity tier. The 990 Pro 4TB's 61/100 value score reflects that premium honestly.
