Disk Performance Test
|
|
##################
|
|
|
|
This test is intended to test the performance of disk devices under Zephyr. It
|
|
was tested with SD cards, but can be used for other disk devices as well.
|
|
The test has the following phases:
|
|
|
|
* Setup test: simply sets up the disk, and reads data such as the sector count
|
|
and sector size
|
|
|
|
* Sequential read test: This test performs sequential reads, first only over one
|
|
sector, than over multiple sequential sectors.
|
|
|
|
* Random read test: This test performs random reads across the disk, each one
|
|
sector in length.
|
|
|
|
* Sequential write test: This test performs sequential writes, first only over
|
|
one sector, than over multiple sequential sectors.
|
|
|
|
* Random write test: This test performs random writes across the disk, each one
|
|
sector in length
