Performance
Select System > Performance from the main menu to configure system preferences.
Note: Some settings suggest that you utilize an uninterruptible power
supply (UPS) before enabling that option. See Power Management
on page 93.
•
Select Enable disk write cache 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
performance, with the drawback that there is a slight chance that unwritten data in the
write cache will be lost in the event of a power failure.
•
The Disable full data journaling improves disk performance at the expense of data
protection. Full data journaling makes a backup of data before writing the data out to
the intended location, which provides the extra level of data protection needed to
prevent data corruption for RAID volumes at the expense of disk write performance.
•
The Optimize for OS X option provides the best performance in Mac OS X
environments when connected to the ReadyNAS through the SMB/CIFS protocol.
This option, however, introduces compatibility issues with Windows NT 4.0; do not
enable this option if this device will be accessed by Windows NT 4.0 clients.
•
The Enable fast CIFS writes option speeds write performance by enabling aggressive
write-back caching over CIFS. Do not enable this option in multi-user application
environments, such as Quick Books where synchronized writes are necessary to
keep files in sync.
•
The Enable fast USB disk writes option speeds up USB write access by accessing
the USB device in asynchronous mode. If you enable this option, do not remove the
USB device without correctly unmounting it. Failure to do so can compromise data
integrity on the device.
