Say, I have a request to read 1GB.

1) Will it be read without interruption until the requested size is read?

2) Or does it read some fixed size(like page size), meaning that it's now responsibility of the OS(or whoever) to make requests to read again and again until the needed size is read, and meaning that another thread could be first to make a request to read from another location(which would be very bad for my thread if it's an hdd)?

Is it same for write operations?

Considering the performance loses in the second case, I would guess that it reads/writes without interruption and it's responsibility of the OS to make "parallel" reads/writes possible.

Could you recommend sources of wisdom on that topic(computer architecture)?

I'm sorry if I didn't describe the question at hand well, I would be glad if you could just recommend what to read on that subject.
