An indication is received that a word line has been read. The word line is part of a plurality of word lines (in solid state storage) which is divided into a plurality of groups. It is determined which group is associated with the read. A count of consecutive, at least potentially uninformative reads is updated based at least in part on the group associated with the read and a group associated with a prior read. It is determining if the count is greater than a threshold and in the event it is determined the count is greater than the threshold, a read disturb check is triggered.
