If you wish to tweak the system performance, select Performance from the main menu. Note that
some of the settings suggest that you utilize an Uninterruptible Power Supply (UPS) before

• NETGEAR recommends that you select the Disable journaling only if the NAS has UPS
protection. Without battery backup, there is a small chance that parity written to a disk in a
RAID set might become out of sync with the data disks if a power failure suddenly occurs,
possibly causing incorrect data to be recovered if one disk fails. Without full data journaling,
disk write performance increases substantially.
• Select Enable disk write cache if you want to allow disk write requests to be acknowledged
by the disk before data is written out to the platter. This can give a big boost to write
