Performance
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
enabling that option:
•
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.
