Zip disks can hold 100 megabytes. Today's hard drives usually hold 250 gigabytes, smaller ones are around 100 gigabytes, and large ones are upwards of 500 gigabytes. One gigabyte is 1000 megabytes, so the typical hard drive can hold 2,500 times more than a zip disk. To answer the question in one word, no.
