Type: Automated Test

Overview

The Storage Assessment Test measures the performance of disks on a computer by using winsat to check if their IO performance data can meet the requirements.

Details

The test passes the disk number of the target test device. It performs the Windows 7 Windows System Assessment Tool (WinSAT) disk format test for the block storage device. It measures the following performance requirements for any visible storage space utilization up to 95%:

Note  % of utilization is % of "used space" seen through the Windows file system.

  • Disk Sequential 64K Byte Read

  • Disk Random 16K Byte Read

  • Disk Sequential 64K Byte Write

  • Average Read Time with Sequential Writes

  • Latency: 95th Percentile

  • Latency: Maximum

  • Average Read Time with Random Writes

Run Time: 90 minutes (depending on the size of block storage)
Log File: storat.wtl
System Restart Required: No
Supported operating systems for Logo or Signature testing:
  • Windows 7

Program: storat.exe

Requirements

Processor

The test tool runs on the following processor architectures:

  • x86

  • x64

  • IA64

Running the Test

If you are testing any drive the requires media, or testing in system-mode on a computer that contains drives that require media, you must insert media into the drives. The media that is used must be formatted.

Because this test case may require a different disk configuration than the other test cases, please run it last to prevent its partition changes from failing other test cases.
