Review
The Samsung 990 Pro is the reference point for PCIe 4.0 NVMe SSDs. On paper it tops the category with up to 7,450 MB/s sequential reads and 1,400,000 random-read IOPS, which makes it a favorite for video editors, 3D artists, and anyone who moves large files daily.
Samsung pairs the speed with a mature controller and LPDDR4 DRAM cache, so real-world performance stays consistent under sustained load — a place where DRAM-less budget drives often stumble. The 5-year warranty and strong endurance ratings make it a safe long-term buy.
The trade-off is price. It carries a premium over rivals like the WD Black SN850X or Crucial T500 that get within a few percent of its speed. If you want the outright fastest, most refined Gen4 drive and budget is secondary, this is the one.
