Yes, test changing the drive configuration to achieve maximum throughput unless you are satisfied with less than optimim speed. I tested multiple settings to achieve maximum throughput on my setup. From the Admin guide (I placed '*' around performance information):
"Block size (per device)
The default is the preferred size of the blocks of data written to new
media in this device.
You can change the block size by selecting another size from the
scroll list, and then clicking OK.
*Some devices (for example, DLT drives) provide better performance
when larger block sizes are used. The preferred block size can range
from 512 bytes to 64 kilobytes.*
Backup Exec does not ensure that the requested block size is in fact
supported by that drive. You should check the drive specifications to
make sure that the block size is supported. If the drive does not
support a block size, it will default to its standard block size.
If the drive does not support block size configuration, this option is
unavailable.
Buffer size (per device)
The default is the preferred amount of data sent to the drive on each
read or write request. The buffer size must be an even multiple of the
block size.
You can change the buffer size by selecting another size from the
scroll list, and then clicking OK.
*Depending on the amount of
memory in your system, increasing this value may improve drive
performance. Each type of drive requires a different buffer size to
achieve maximum throughput.*
Buffer count
The default is the preferred number of buffers allocated for this
device.
You can change the buffer count by selecting another count from the
scroll list, and then clicking OK.
*Depending on the amount of memory in your system, increasing this
value may improve drive performance. Each type of drive requires a
different number of buffers to achieve maximum throughput.*
If you change the buffer count, you may need to adjust the high
water count accordingly.
High water count
The default is the preferred number of buffers to be filled before data
is first sent to the drive, and any time after that if the drive
underruns.
You can change the high water count by selecting another count
from the scroll list, and then clicking OK.
The high water count cannot exceed the buffer count. A value of 0
disables the use of high water logic; that is, each buffer is sent to the
drive as it is filled.
*The default setting provides satisfactory performance in most
instances; in some configurations, throughput performance may be
increased when other values are specified in this field. If you increase
or decrease the buffer count, the high water count should be adjusted
accordingly.*
If a drive has a high water count default of 0, it should
be left at 0.
