"Many users assume that their advanced filesystem is better than UFS because they have so many features—snapshots, checksums, compression, sophisticated caching algorithms, and so on—while all UFS has ever done is muck about putting data on disk. But, conversely, UFS users believe their filesystem is better for exactly the same reasons."
