A

The I/O performance of reading and writing 1-MB files of a Seagate ST500DM002-1BD142 ATA HD can be measured by running SQLIO with multiple 1024-KB blocks with a large stripe factor.

Here is the read performance test of Seagate ST500DM002-1BD142 ATA HD on Azure VM with 1024-KB blocks.

C:\fyicenter\SQLIO>sqlio -LS -kR -b1024 -i64 -f64 -t1 -s30 -p0

CUMULATIVE DATA:
throughput metrics:
IOs/sec:    72.48
MBs/sec:    72.48
latency metrics:
Min_Latency(ms): 4
Avg_Latency(ms): 13
Max_Latency(ms): 211
