A

The I/O performance of reading and writing 1-MB files of a Seagate INTEL SSDPEKKF256G8L SSD can be measured by running SQLIO with multiple 1024-KB blocks with a large stripe factor.

Here is the read performance test of Seagate INTEL SSDPEKKF256G8L SSD on Azure VM with 1024-KB blocks.

C:\fyicenter\SQLIO>sqlio -LS -kR -b1024 -i64 -f64 -t1 -s60 -p0
