Hi guys I have question about how two different Hard disk setups can possibly affect performance of my database.
I have two Options.
One Physical Harddisk and then Multiple Virtual hard drives for SQL Server's Database files (.mdf , .ndf),Log files, TempDB, Backups etc
One Physical Harddisk and then One huge Virtual hard drive for SQL Server's Database files (.mdf , .ndf),Log files, TempDB, Backups etc
To my knowledge, If these were all physical hard drives, having multiple drives for all these files (tempDB, Log file, backups, database files), would definitely benefit from parallel processing.
But is there any drawbacks of having one massive Virtual Hard drive vs multiple Virtual Hard drives as in reality, when Sql Server is reading or writing , it will be all done from one Physical Hard disk?
Is one method preferred over other? Any suggestions or pointers in the right direction is much appreciated. Thanks
