The Samsung 990 Pro is the next generation of the popular 980 Pro, offering significantly enhanced performance. Samsung boasts a 50% improvement in performance per watt compared to its predecessor. With sequential read speeds of 7,450MB/s and write speeds of 6,900MB/s, along with random speeds of 1400K/1550K IOPS, this SSD is a powerhouse. It uses Samsung's new Pascal controller and 7th gen TLC NAND flash chips, all manufactured in-house, setting it apart from competitors. Although the WD Black SN850X and SK Hynix P41 Platinum are also top performers, the Samsung 990 Pro consistently outshines them in benchmarks.

Is the Samsung 990 Pro Compatible with the PS5?

The Samsung 990 Pro is a stellar choice for your PS5. While its performance far exceeds what the PS5's stock SSD can handle, its speed of 7,450MB/s read is well beyond Sony's recommended minimum of 5,500MB/s. At its current price, it's even more economical than many slower alternatives. Sony recommends using a heatsink with your SSD, and this model of the 990 Pro comes equipped with a robust, all-metal heatsink that fits perfectly within the PS5's SSD slot.
