used in normal operation, performance may be degraded. This
new feature there are 4 options; Disabled, Mode1, Mode2 and
Mode 3. Default value is Disabled. Our controller cache uses LRU
method, there have no special memory capacity reserved for read
or write. The Mode 1, 2 and 3 are used for define the command
sorting method. The default sorting method is helpful for normal
applications, but not useful for AV applications, so we have de-
fined three different sorting methods for these special applica

tions. To decide how to optimize AV stream recording parameter,
you need to adjust the Optimize AV Recording, and Write Buffer
Threshold during runtime.
