RAID 0 128K Sequential Read/Write
The 128K sequential speeds reflect the maximum sequential throughput of the HDD using a file size encountered in normal NAS usage.
The WD Red array averages a tremendous 537 MB/s average, while the Se only beats it slightly with 610 MB/s in our sequential write testing.
The WD Se array averages 651 MB/s of sequential read speed, and the Red trails with 555 MB/s.
When we test mixed read/write performance the gap between the two RAID arrays closes significantly.
The WD Se array beats the array of WD Reds, with the main variation occurring in the 10-40ms range.
