Preference – MODE / CACHE / MISC:
User can enable / disable any MODE, adjust the Cache, and change the password.
Preference – MODE:
• Disk Lag Proof: Disk lag on a single drive of a RAID set introduces delays in delivering data from an entire
RAID set. Disk Lag Proof Mode limits these delays by regenerating data from parity and returns data to the host
on time. (This function will cause minor performance loss. Does not support JBOD and NRAID.)
• NCQ: Native Command Queuing allows several outstanding commands to be given to the drives at one time,
therefore increasing the performance of the hard drives. (Recommend)
• SMART Mode: user will define the time length for SMART mode; it will monitor the performance of the hard
drives to predict hard drive failure during this period of time.
• Beeper: active the audio alarm on the product in the event of an error or initialization. (Recommend)
• Active Sustained Transfer Technology: this mode will smooth the performance of sequential I/Os and reduce
fluctuation (peak performance will be reduced). For video editing, this function will help prevent video frame
drops. (Recommend)
