What file access pattern is particularly suited to chained file allocation on disk? Chained, or 'Linked List' allocation, like contiguous allocation, is useful for when dealing with large, sequential files. The first word of each block is used to point to the next one in sequence. It is fine for sequential access because every block needs to be read regardless. It's a living nightmare for random access files because we introduce a lot of unnecessary, wasted “read” operations to the FS.
