| Feb 27, 2015 at 20:01 | comment | added | misha256 | @KorayTugay No problem. Your 2-byte example works like this: The 2 Bytes will be packed into 4096 Bytes by NTFS. Then, the 4096 Bytes will be split up and sent to the disk as eight consecutive blocks of 512 Bytes. | |

Internally, SSD hard drives implement another layer of block-logic that's transparent to the PC/OS called pages. As if that's not enough, modern file-systems have their own block-logic too (e.g. NTFS default is 4096 Bytes). In all these cases data is being packed and unpacked to create the required blocks or extract meaningful data from such blocks. | |
