Claim 15:
16. The method according to the claim 13, further comprising:
managing a third block set corresponding to a third remaining time represented by a multiple of the unit time, the third block set being a set of blocks in which a remaining time, until the time point at which the rewrite operation is to be performed, is the third remaining time which is longer than the second remaining time;
setting threshold;
determining that the first remaining time and the second remaining time are less than or equal to the threshold, and the third remaining time is greater than the threshold;
in response to determining that the first remaining time and the second remaining time are less than or equal to the threshold, and the third remaining time is greater than the threshold,
calculating the first rewrite speed, and the second rewrite speed;
determining the maximum rewrite speed of the first rewrite speed and the second rewrite speed; and
performing, at the determined maximum rewrite speed, the rewrite operation on i) the first number of blocks included in the first block set and ii) the second number of blocks included in the second block set.
