It boasts read speeds of up to 5,150 MB/s and write speeds of up to 3,483 MB/s, making it an excellent choice for gamers who need quick load times and responsive performance. The drive's PCIe Gen4 interface ensures that it can handle demanding gaming workloads efficiently.
Random 4K Performance
In random 4K performance tests, the WD_BLACK SN770 excels. It offers top-tier performance, which is particularly beneficial for gaming handhelds like the Steam Deck. This is evident from its high IOPS (Input/Output Operations Per Second) scores, which are crucial for maintaining smooth gaming experiences.
Sequential Performance
While the WD_BLACK SN770 does not excel in sequential performance compared to some of its competitors, it still delivers respectable speeds.
