Yeah, with those caveats. But how do you make sure they apply? If someone does manually muck about with the blob store, or it does lose blobs due to corruption, then your transaction is retroactively "un-atomicized" with no trace thereof in the actual DB.

If corruption happens then any guarantees by the hardware are voided, and the software guarantees (of durability) which are built o the hardware guarantees are equally voided. So corruption -> dead in the water.

But otherwise I agree.
