1) Suppose I have a 5 disk RAID 0 array.  Each disk can read 100M/sec.  What is the total read throughput of the array?


2) Which would likely offer higher performance( more requests satisfied per second), a disk scheduled using SCAN or a disk scheduled using circular scan?


3) In EXT2, which would you write to disk first?
   The data blocks of a file
   The inode of the file

4) In VFAT, how many directory entries would the filename "123456789.txt" require?

5) Which stores more data, a 2 disk RAID 5 array or a 2 disk RAID 1 array?

6) Does first come first serve disk scheduling offer better performance to files located near the edges of the disk?

7) In EXT2, are there directory entries that point to no inode?  If so, offer a situation where this happens.

8) In VFAT, how can you tell the count of how many clusters are free (unused) on the disk?

9) Name a location that would be quick and easy to read right after just reading (sector = 100, track = 200, head = 1). 

10) In EXT2, how does a file system increase the number of inodes?

11) In VFAT, how many FAT entries are needed per file system.
