Uncompressed is indeed acceptable, but there are many drawbacks using it.

The main ones are:

- Enormously greater requirements for network/disk throughput - and
storage capacities
- Lossless compression allows more backup copies for the same price
- No integrity information (like FFV1.3's slicecrc) - and possible lack
of other metadata
