Allocation Unit Size (AUS) when formatting drive
Blocks are stored in large contiguous files (gigabytes), and are effectively append only, so they don’t really make any sort of impact on performance. 

The high write cycle is in a several gigabyte leveldb database, but this is heavily write cached. Performance is almost always single core limited on any sort of fast storage given sufficient memory, rather than any other other factor. 

You’ll only see storage as a factor when using magnetic media or excruciatingly slow flash storage like a SD card.
