- Does caching disk write operations have any advantages or disadvantages?Question#4: Consider a file system that uses inodes to represent files. Disk blocks are 8 KB in size, and a pointer to a disk block requires 4 bytes. This file system has 12 direct disk blocks, as well as single, double, and triple indirect disk blocks. What is the maximum size of a file that can be stored in this file system?I was wondering what the pros and cons of caching disk write operations were.
- What are the four primary categories of external disk interfaces?Simply said, disk prefetching is exactly what it sounds like. What are the positive and negative aspects of it?Suppose that a magnetic disk has an average seek time of 4 ms, a rotation rate of 5400 RPM, a transfer rate of 50 MB/second, a sector size of 512 bytes, and controller overhead of 2 ms. What is the average amount of time to read a single sector?
