TerraMaster Dxx and APFS compression/deduplication
Posted: 04 Feb 2022, 03:15
Hello,
maybe it will be useful for some of you folks, so sharing here. I have TerraMaster D16 and I use it for work and backups. I have 8x18TB WD GOLD HDDs in RAID 6 and 4x2TB SSDs in RAID 0 and 4 empty bays for the future. I am using it with the most recent macOS.
The 8 HDDs RAID 6 I formatted to APFS and yes, I am aware that the performance sucks if you have a lot of files and folders but this RAID 6 is in my case used mostly as storage for infrequently used data (which after some time are moved to Amazon Glacier archive anyway). The 4 SSDs RAID 0 is in my case used as temporary storage (editing, compression, etc.).
While having the APFS on the RAID and having a lot of compressible and duplicated data I decided to use APFS compression and APFS deduplication. Apple does not provide any nice GUI tools for compression/deduplication, but there are command-line tools you can use. I wrote a short HOWTO on Medium which may be useful for you in case you decide to compress/deduplicate your APFS volumes.
