The Samsung 990 Pro is also excellent at sustaining strong write performance. If you’re writing continuously for several minutes on most drives, you’ll notice a huge performance drop as the the data fills up the high-speed cache and ends up using the slower TLC NAND Flash. We test sustained write speeds using Iometer for 15 minutes.

In our tests, the 4TB 990 Pro was able to maintain a speed of 6.2 GB/s for 75 seconds thanks to its generous 10GB of pSLC cache. Once the data spills over into the TLC, it operates at a – strong, compared to most drives – 1.6 GB/s.
