Positioned as a reliable backup alternative to CD-RW drives, the Zip 750MB USB 2.0 External now reaches a capacity sweet spot, putting Zip back to the race with optical drive in the removable media market. At $15 apiece, the new 750MB Zip disks sell for the same price as the Zip 250MB before the launch. Technically, the media cost has went down quite substantially, but it’s still sky high compared to an average $2 CD-RW disc. It’s unfortunate that the media cost hasn’t gone down in all these years. While Zip 750MB couldn’t compete with its cost, the media hard plastic is less vulnerable to scratches than optical disc.
