Hey Fedi!
I need to convert a 4TB RAID array. I will move the data off it and then back. Currently it's NTFS (and Windows). When I'm done, it will be LVM+EXT4 (and Linux).
Does the file system of the intermediate storage make any difference to the speed or otherwise? If yes, what would be best? (I might hit the 4GB file size limit on FAT32.)
Also, is this best done by copying files, or would it be faster (probably not safer) to manipulate the existing partition?
