I have a i9 2019 iMac with 1 TB SSD. I get one day 1.9 MB/s write and 2.5 MB/s read and other day 1.7 MB/s write and 1.9 MB/s read. Sometimes it gets down to 1.6 MB/s write and 1.3 MB/s read. Sometimes it gets up to 2 MB/s write and 2.6 MB/s read. Why is it that I get these inconsistent results? Anybody with same experience?
