A

The I/O performance of reading and writing 64-KB files of a Seagate INTEL SSDPEKKF256G8L SSD can be measured by running SQLIO with multiple 64-KB blocks with a large stripe factor.

Here is the read performance test of Seagate INTEL SSDPEKKF256G8L SSD on Azure VM with 64-KB blocks.

C:\fyicenter\SQLIO>sqlio -LS -kR -b64 -i64 -f64 -t1 -s300 -p0

using system counter for latency timings, 1945315 counts per second

CUMULATIVE DATA:
throughput metrics:
IOs/sec:  9798.12
MBs/sec:   612.38
latency metrics:
Min_Latency(ms): 0
Avg_Latency(ms): 0
Max_Latency(ms): 71
