2379446943762 = 0x22A02170012

So that is 0x217 * 60,000 = 32,100,000 non-aligned sectors written

Which, at 512B per sector, comes to 0.0149 TiB.

0.0149 / 20.0572 = 0.0745%

Or about 1 in 1342 bytes written is not 4K aligned. I wonder where that ratio comes from. Is that the ratio of random bytes written to total bytes written by Anvil's app?
