    80+ filegroups is too much for that size of a database.

    80+ files is also a big number, but it's more normal for files.

    There are benefits of having multiple filegroups. Do you have a reason for having such many filegroups?

    I've worked on 100-500GB databases. They were having 15-20 filegroups and double number of files.

    However you can see in the survey that there are databases like yours.

    Sorry I wasn't very clear. There are four file groups all residing on one RAID10 volume:

    Primary: one file

    Filegroup2: forty files

    Filegroup3: forty files

    Filegroup 4: one file

    I was told that this was done to reduce read and write latency but i just can't find any evidence that this is correct.
