Data and log sits on different disk drive.

Hi,
Can I create a database with the .mdf (data) and .ldf (log) on 2 different d
isk drive? Is there any benefit of doing it in term of performance? How abou
t backup and recovery?
Thanks.Hi,
That will be a very good approach to reduce the Disk I/o and increase the
performance. I recommend you to create multiple file groups
to keep the data and Index as well.
Backup and Recovery will of same sort as normal. If you have File groups you
will be able to backup and restore file group wise.
Have a look into this article (Read the Disk I/o Part).

better performance, you should always keep the log and data on separate
physical drives ( not just a different partition on the same drive.)
This separates serial IO ( log io) from random IO (Data rows) which allows
for better performance. The log should be mirrored...
Here are the data placement rules.:
1. Keep log away from data
2. Keep data away from master, model
3. Mirror the log
As Hari says, there is no difference in regard to how backup is done..
