write back cache enable

How to improve hard drive write speed with write-back caching.
Is there a KDE disk utility tool.

openSUSE Leap 42.1

If there is a tool in 42.1, I can’t see any reeason to expect a KDE tool, but Yast is the place where you’d expect it to be.

Already searched within Yast.

No GUI utilities

command line
hdparm -W /dev/sda

To see if it is on May well be as default
hdparm -W1 /dev/sda

to turn on

hdparm -W0 /dev/sda

turn off

data residing in the hard drive’s cache do not get a chance to be stored
and a lost. This fact is especially important for database system. In
order to disable write-back caching set write-caching to 0:

Ok thanks.
