Suppose you need to sort a relation of 40 gigabytes, with 4-kilobyte blocks,using a memory size of 40 megabytes. Suppose the cost of a seek is 5 milliseconds, while the disk transfer rate is 40 megabytes per second. Suppose a flash storage device is used instead of a disk, and it has a latency of 20 microsecond and a transfer rate of 400 megabytes per second. Recompute the cost of sorting the relation, in seconds, with bb = 1 and with bb = 100, in this setting.
