Although solid state drives (SSDs) have become mainstream, disk platters are likely to be spinning for quite a while. This earlier 5.25" drive with 14 platters held 9GB in total. Today's disk drives have a thousand times as much data in that same amount of platter space. (Image courtesy of Singapore Technologies.) |
