Good afternoon, I'm installing a new database server with enterprise SSD on windows server 2022. My database has 700GB of mdf and 350 LDF.

I'm going to create the partitions SWAP - SQLDATA - SQLLOG - SQLTEMPDB - SQLMSDTC - SQLBACKUP, my doubts which file system format the partitions to have a better performance, NTFS or ReFS and the size of the allocation unit 64k, 128k, 256k, 512k, 1M or 2M.

Thanks for the help.

    Hi @emerson guimaraes

    NTFS with a 64K allocation unit size is the most common case.

    From what I've searched, ReFS is a newer technology and it may have some bugs that we haven't found. While NTFS has always been around, it's a proven file system at this stage.

    For more details, you can refer to these links:
