Default is 15 seconds 2 Drive I O Timeout sec gt Drive side Parameters The Drive I O Timeout is the time interval for firmware to wait for a drive to respond When the drive itself detects a media error while reading from the drive platter it usually retries the previous read or re calibrates the head When the drive encounters a bad block on the media it reassigns the bad block onto a spare block However it takes time to perform the above procedure The time to perform such procedure can vary between drives of different brands and models The default setting for I O timeout is 7 seconds It is recommended to keep the default Maximum Tag Count This feature facilitates the support for both Tagged Command Queuing TCQ and Native Command Queuing NCQ ICQ is a traditional feature on SCSI and Fibre disk drives while NCQ is recently implemented with SATA disk drives The queuing feature requires the support of both host adapters and hard disk drives Command queuing can intelligently reorder host requests to streamline random accesses for OPS multi user environments The default setting is Enabled with a maximum tag count of 32 SCSI Fibre drives or 4 for SATA SAS drives Embedded RAIDWatch User s Manual 9 12 AN CAUTION Disabling Tag Command Queuing will disable the hard drives built in buffer Although Command Queuing can boost performance however data cached in drives buffer will be aff
