It exists various storage device, file, block and object based. Some filesystem are dedicated to a kind of device. what about Btrfs ?

Here I would like to get some technical facts about Btrfs over a block storage device. Indeed, most of cloud provider documentation use another file system. Which lead to this legitimate question.

Moreover is their for Btrfs some interesting mount option to apply for a block storage ?

Thanks for your highlight

btrfs is very slow for rewrite-heavy workloads; moreover, it fragments horribly and slows down each time you create a subvolume or snapshot.

I would use it only for pure fileserver duties rather then block device emulation, databases or virtual machines.
