I am currently about to upgrade from 1.x to 2.x and also upgrade my harddisks from 1TB to 3TB (see my other question here: Update from 1.18 to 2.x before or after hard disk upgrade?).
At the moment the internal disks (2 disks in Raid1 and 1 disk as backup, mirroring the raid "manually" 1-2 times per week via Rsync) are formated as Ext4.
So from 1TB OMV shows me a total volume of 916,89 GB per disk.
I also have 2 portable external disks for rotating offsite backups (via the USBbackup plugin). Those are formated as NFTS so they can be easily accessible from Windows Computers in case something happens with the OMV installation and we need to access the backups.
What I noticed is that there is far more space available on the external drives running on NFTS than on the internal drives with EXT4. This might have different reasons, but I was wondering if the way how a disk is formatted has an impact on how much space is available on the disk?
Our data structure is very divers. We save a lot of small office documents (Excel, PPT, DOC, PDF and images), but also some bigger audio files and some pretty big video files from our projects. The majority of files (in number) are small ones of course. So I was wondering if I can optimize the format/filesystem of the disks for my use case?
Or do I just format them EXT4 (the internal ones) and thats it?
