It is the mini size for 1986.bigger is better

On the left is a segate st-225 on the right is a Maxtor xt-1140. The Maxtor is a full height drive with 140 MB of space. In 1984 this drive would cost $3379. The segate is a half height drive with only 20 MB of space. In 1986 it cost $389. I wanted to point out that The Maxtor cost ten times as much as the segate and has seven times the amount of hard disk space.
