  Was hoping for something I could read rather than watch.

    Try https://lwn.net/Articles/476263/ https://lwn.net/Articles/476263/ then, which is a summary of Dave's talk on the state of XFS. The TL;DR version would be that XFS aims to be get out of your road and provide a big, fast pipe to make optimal use of your available hardware. It does not try to implement end-to-end checksumming, thin provisioning, RAID, data de-duplication, or other overhead. Dave makes the point that traditionally people characterised XFS as for very high-end workloads, but suggests that commodity hardware is now at the point (in terms of IOPS and transfer rates) that "high end" is now quite affordable, so you should consider it for workstations, laptops, etc. The XFS authors think it will remain a better choice for certain workloads, such as the modify-in-place work of databases, video editing, and so on, that copy-on-write filesystems like ZFS and btrfs.
