Recently acquired an Addlink S90 2TB NVME to run in an Orico T3 drive & quite impressed with the speeds.
BM is showing approx 2500 read/write & with Amorphous i'm hitting 2800/2700, but heres the thing.
Occasionally the drives read speeds drop to around 1200 whilst maintaining high 2500 write speeds during a brief looping session of approx 5 minutes. Seems a sequence. 3 high read rates, drops to approx 1800 for a run, then drops all the way down to 1200 for 5 or 6 runs before starting the process all over again. Write rates however are not affected. More bizarrely, I can exit BM, immediately relaunch & restart the runs & hit a constant 2500/2500 without any drops whatsoever.

This to me doesn't seems normal behaviour.
Any ideas?
