Surprising results for 27" iMac Retina 5K (mid 2017):

TESTED: 2017 iMac 5K SSD Speed vs 2015 iMac 5K (Surprising Finding)

Thus the '''2017 iMac 5K is substantially slower for everyday tasks that involve intensive I/O with smaller reads''', in spite of the 40% greater speed for large reads.


2017 iMac 5K: Flash Drive (SSD)

2015 iMac 5K: writes at 1520 MiB/sec and reads at 2075 MiB/sec

'''2017 iMac 5K: writes at 2102 MiB/sec and reads at 2915 MiB/sec.'''



That is less read speed than Samsung 960 PRO with sequential R/W (read/write) speeds up to 3,500/2,100 MB/s and random R/W speeds up to 440/360K IOPS, respectively.
