The hashes are in internal byte order; the other values are all in little-endian order.

The storage size of the Bitcoin (BTC) blockchain is increasing with every additional block, at a rate of: (size of the last block) / (time to mine the last block) Since blocks are mined about every 10 minutes, and most new blocks are almost at the 1 MB blocksize limit, this rate has become about 1 MB/10 min = 6 MB/hr = 144 MB/day

Some of the altcoins, like Bitcoin Cash. The BCH blocks were initially 8MB, currently a BCH block is It's known as a transaction block chain, and I've put a description of the transaction block chain right here.
