To view the disk drive information, click the E# Slot# link from the Raid Set Hierarchy

disk capacity, timeout count, media error count, and SMART information.
5.6.1.1 Hdd Xfer Speed
“Hdd Xfer Speed” is a firmware-level hard disk / SSD speed function that is used to
measure the drive’s performance. “Hdd Xfer Speed” will perform read tests without
overwriting customer data. The read-only palimpsest benchmark of the disk is shown in
the device information. If the value drops below the normal curve, something may be
wrong with the disk. User can use “Set Disk To Be Failed” function from remote side to set
a slow speed disk as “failed” so that volume will be not stuck by the slow speed disk after
rebuild.
“Hdd Xfer Speed” result can be accessed by clicking on the “Device” from the “RAID set
Hierarchy” you wish to scan, clicking on the “Show Result”. This allows you to set up a
scan environment which runs the test by clicking “Test Disk Speed” on the right screen
setup option. If more than one drive is checked when you set the ‘Disks To Be Tested’, it
will run that test for the number setting drives.
