Yes it can. It uses algorithms I previously mentioned -- scatter read,
gather write, elevator seeking -- to assemble together large sequences of
I/O requests, larger than any on-drive cache can handle.
No, it can not. It does not have the access.
For SSD, no. SSD is a device that mimics a hard drive with 'sectors' and 'tracks'.
It *dynamically* (for wear levelling) maps between a 'virtual hard drive' and its underlying weirdness of flash RAM blocks and pages.
There is nothing the operating system can do to optimise this except not do multiple writes to a 'sector' if possible.
