CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V6.0.
Samsung's SSD 970 EVO is a strong performer in the CrystalDiskMark benchmark, especially when it comes to 4K writes – both at shallow and deeper queue depths. Comparing the two benchmark result screens (default config vs 0 fill) it appears that the new Phoenix controller isn't too fussed about what type of data it's asked to deal with.
