4. (24 points) File systems: organization This problem asks you to assess file access time for each of the three file systems (FAT, FFS, NTFS) discussed in class. Assume, in all cases: Each disk block is 8 KB The time required to access a new disk block is 20 ms Once a disk block is accessed for the first time, it remains cached in main memory, and every access to the cached block after the first one will take 2 ms. . Determine the worst case access time for a single read operation to an undetermined word of data in a 16 MB file if the file system used is (a) FAT, (b) FFS, (c) NTFS. For NTFS, assume all records in the MFT fit in a single disk block, and the file in question requires 4 MFT records to store all necessary metadata. 4.
