There are three options for setting the write cache: If the system is safeguarded by UPS, the enabling of the hard disk cache is recommended for performance reasons. Stux and TheBloke like this. But like you said not much point as you could just go to their respective website and do the same thing I’m fairly happy with the above now.

Stux and TheBloke like this. If sxs data block is requested, “Read ahead” causes further sequentially following data blocks to be already read from the hard disk to the cache of the controller just in case, and in the hope that they will be called for in subsequent requests.

Maybe that becomes another page but probably not too useful. If you have a controller and have successfully cross flashed or done something worthy, reply back here and the list will be updated.
We break it down. Yes, my password is: The “Always Write-back” option enables the write cache on a permanent basis; it is also used if the battery of the BBU is empty or if no BBU is installed, whereas the “Write-back” option automatically switches to “Write-through” as long as the controller cache is not battery-buffered.
