What exactly is "Optimize disk I/O while CPU is idle" do?

[g440i]

Hi,

 

I'd like to know what exactly is "Optimize disk I/O while CPU is idle" do?

 

I'm using a SSD and I'm afraid it's a scheduled defrag which I don't perfer on a SSD.

 

Thanks!

Hi g440i.

Where can you see that option? (Because I can't see it)

In the latest version of wise registry cleaner 8.12.534, there is optimize disk i/o Subsystem to improve system performance.

Hi g440i.

My version is 8.11.533, it's in the system tuneup

BTW, what is that optimize disk i/o Subsystem to improve system performance do?

Because I'm using SSD, I'm concern on both those optimize disk i/o features. I think it's for HDD and may be harmful to SSD.

I think it changes the value of NoLowDiskSpaceChecks from 0 to 1.

(in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer)
Check: Description of the Low Disk Space Notification in Windows XP
That should also be valid for newer Windows versions.
If you want more certainty, wait for WiseCleanerAdmin's response (or developers'response).

Yes, xilolee is right.

This optimization  is safe to SSD.

So, all those "optimize" for disk i/o are just disable notification, which is somewhat useless?
