The HyperX Savage EXO peak reads come at the 4MB block level at 481.08MB/s before dropping back slightly to finish the test at 472.96MB/s.
At the 512KB block mark, the write performance falls away to 362MB/s before gradually picking up to peak at 498.88MB/s at the 4MB block mark before once again dropping back to finish the test run at 352.27MB/s
Samsung's TS still reigns supreme for all the non NVMe SSD external drives we have tested when it comes to peak read performance in our throughput test at 496MB/s.
In our write throughput test it's the Western Digital My Passport that still holds sway with peak write performance of 504MB/s. The Kingston Savage EXO keeps pace with it for a while but the performance drops off dramatically at several block sizes during the test run.
