Why do certain disk write operations get cached while others don't, and why?
Step by step
Solved in 3 steps
- What are the advantages of caching disk write operations, and what are the potential drawbacks?When an operating system reads a file, it reads a series of blocks that are sequentially stored on the same physical disk block. What's the big deal with magnetic disks, anyway? Do solid-state drives (SSDs) still serve a purpose, or are they obsolete? Could you please explain this?How can caching write operations on a disk help and how does it hurt?
