"Enable Advanced Performace" for disk drives

Anyone have this option enabled (under the Policies tab) and noticed any
difference in performace?

I recommend disabling it to reduce chances of data corruption.

With it disabled, the HDD operates in write-through cache mode,
in which all data that gets written to the drive is immediately written
to the disks and also stored in the cache. Writes are not cached, but reads are.

When the option is enabled, the HDD operates in write-back cache mode,
in which all the data that gets written to the drive is first stored in the cache,
and then later written to the disk. Both writes and reads are cached in this case.
