hIOmon SSD Performance Monitor - Understanding desktop usage patterns.

[Anvil]

Hi Overthere
I've been swamped with a head cold and so I haven't read all of your analysis, will do later tonight.
I did notice that the number of I/Os seemed low compared to what one would expect, it might just do a "sample" number of I/Os, I'll redo the test using a smalller testfile just to see what happens.
It's not an issue as long as ATTO is performing the same number of IOs for that exact testfile size, or it might just be that ATTO isn't built for SSD speeds

Ao1,
Your assumption about the SSD (most SSDs) isn't exactly stressed while doing normal desktop tasks is as expected, the X25 is not even close to being stressed.
At the same time, there is a difference between SSD controllers, application loadtime can differ quite a lot, you should have had a SF or C300 to compare with the Intel

The difference between single drives and raid should show up once the task is starting to stress the SSD controller.
You could try monitoring an AS SSD run using sinlge, raid-1 and raid-0.
AS SSD, being a synthetic benchmark would of course not reflect normal desktop usage but it will show when there is a point in adding an extra SSD for more throughput/iops.

My VM tests does show improvement going from a single drive to raid, at the same time the number of seconds used by storage compared to the runtime length shows that most of the time the SSD is just waiting.
(meaning there are now other bottlenecks in the system)
