So, I am leaning towards format the drive as FAT32.In order to install macOS, you’ll need an external drive with at least 12GB of free space. The current MacBook lineup only has Thunderbolt/USB-C ports, but that's OK because USB-C is fast, future-proof, and will likely replace standard USB, HDMI, DisplayPort, power, and more. Is the only limitation of FAT32 that it can't write files larger than 4GB? I don't have any files that large, but I definitely would need to format the volume as 2TB, not 32GB (as I understand that 32TB volume limitation is no longer a problem?). I know that to get exFAT support on the DS, I would have to purchase the exFAT Access package. The Mac can read and write to FAT32 and exFAT, and read only from NTFS drives.

I know that my particular model of DS supports reading HFS+, but cannot write to HFS+ (although some newer models can).Īccording to this KB article from Synology, the Synology software can only format external drives as ext4 and FAT32. Currently it is a 2TB HDD formatted as HFS+ (Mac format, before APFS). My question is about which file system format to format the drive as. My understanding is that HyperBackup would create a backup that was not readable by plugging the drive into a Mac. I know there are lots of options out there, such as using HyperBackup etc, but I would like to use USB Copy because I would like to be able to plug this external drive into my Mac and have access to all the files that are stored on it (a copy of what is stored on the DS). Currently there are about 380GB of files on the DS. I am going to be using it with a DS215j to backup a 2TB mirrored array using USB Copy.

I am looking for recommendations on what file system format to use for an external USB drive.
