Flush performance varies by 6x and is not necessarily correlated with overall perf or price. If you are doing lots of database writes or other workloads where durability matters don't just look at the random/sustained read/write performance!

High flush perf: Crucial P5 Plus (fastest) and WD Red

Despite being a relatively high end consumer drive the Seagate had really low flush performance. And despite being a budget drive the WD Green was really fast, almost as good as the WD Red in my test.

The SK Hynix drive had fast flush perf at times, then at other times it would slow down. But it sometimes lost flushed data so it doesn't matter much.
