I have a quick question to all of the FDB users in the community.  
What filesystem do you use for FDB? Why did you choose it?  
Can you share some thoughts or performance data if you have any?

👋

A bit off-topic, but the docs [suggest](https://apple.github.io/foundationdb/configuration.html#Filesystem) using ext4.

NTFS!

… but I suspect that I’m not exactly a representative sample 🙂

Of course we also use ext4 for newer systems.
