Not sure this is where to ask, so apologies if it's not here.
Is BTRFS always the default FS for Garuda, regardless of where it is to be installed?
I ask, because according to:
[Samsung 870 QVO SSD Performance On Ubuntu Linux Review - Phoronix](https://Phoronix QVO 870 tests)
BTRFS, at least on this SATA SSD, is pretty poor.
I just bought a 4TB model and did a quick benchmark with KDiskMark to compare BTRFS and Ext4 on it (fresh formatted partitions), and the difference is quite significant in places:
KDiskMark (3.1.2): https://github.com/JonMagon/KDiskMark
Flexible I/O Tester (fio-3.33): https://github.com/axboe/fio
- MB/s = 1,000,000 bytes/s [SATA/600 = 600,000,000 bytes/s]
- KB = 1000 bytes, KiB = 1024 bytes

I'm just wondering why there seems to be big differences, whether it is due to it being a SATA SSD, or the tech used in the drive?
