Hi.
I actually do my first implementation of a SQL Server DWH based on SSDs and our admin ask me to reduce the initial file size because of the behavior of the SSDs. With normal harddrives I setup the size fixed to the size of the volume, to avoid performance issues because of multiple auto-growth because we have a 1:1 relationship of files and drives.
Is there a best practice how to handle this with SSDs? I found this benchmark which cover this question, but give not an answer how to setup it in the best way.

There are 2 two topics he told me:
1. SSDs needs space to handle damaged blocks. So performace will slow down with higher usage of storage.
2. Windows needs some space to handle special SSD task so we should not use the whole space available.
Thanks in advance,
Nils
