What is the 1-MB I/O performance of Seagate ST500DM002-1BD142 ATA HD on Azure VM?

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.
