Event 1 IBM's 9345 hard disk drive
IBM's 9345 hard disk drive is introduced. Codenamed "Sawmill," it was the first hard disk drive to use magneto-resistive heads. Magneto-resistive heads gave the 9345 an advantage over its competitors, as the bits could be stored more densely. The first model of this 5 ¼-inch disk drive had two 1 GB hard disk assemblies (HDAs) and the second model had two 1.5 GB HDAs.

Event 2 Prototype SSD Module
A prototype solid state disk (SSD) module is made for evaluation by IBM. SanDisk, which at time was known as SunDisk, manufactured the module which used non-volatile memory chips to replace the spinning disks of a hard disk drive. SanDisk recognized that handheld devices and computers were becoming lighter and smaller, and that flash memory, as was used in the SSD module, offered powerful advantages over hard disk.

Event 3 Compact Flash
When CompactFlash is introduced by SanDisk, it is quickly adopted and becomes the preferred memory storage option in many consumer as well as professional electronic devices. It was highly popular in digital still and video cameras, and although its dimensions were slightly larger than some other memory card formats, its ruggedness and high capacity made it a preferred choice.

Event 4 Iomega Zip Disk
The Iomega Zip Disk is released. The initial Zip system allowed 100MB to be stored on a cartridge roughly the size of a 3 ½ inch floppy disk. Later versions increased the capacity of a single disk from 100MB to 2GB. Like hard disks but unlike other floppies, ZIP drives used a non-contact read/write head that “flew” above the surface. Reliability problems and low-cost CDs eventually made ZIP disks obsolete. Website-www.computerhistory.org/timeline/1994/#169ebbe2ad45559efbc6eb35720596e3 -
Event 5 The Compact Disc-ReWritable (CD-RW)
The Compact Disc-ReWritable (CD-RW) is introduced. This optical disc was used for data storage and in the backing up and transferring of files to various devices. It was less robust than some contemporary storage media, and could only be re-written roughly 1,000 times. Website-www.computerhistory.org/timeline/1997/#169ebbe2ad45559efbc6eb35720f30a5
