Am I missing something or is there something wrong here?
The Samsung drive has a higher random read IOPS rating than the P4800X, but it has an even larger advantage in random write IOPS, which is emphasised in the sequential read/write bandwidth numbers where it is two and a half to three times better.
Yet the table shows P4800X read & write rate as 550K & read bandwidth of 11.2 while write is 8GB/s
Then shows the SZ985 having 750K reads/s but only 170K writes/s and bandwidth figures of 3.2GB/s for both reads and writes.
