Iomega introduced the 100MB Zip drive in early 1995. The Zip stores more than 70 times that of a 1.44MB diskette and is several times faster. However, they are not bootable; therefore, they cannot function as the a: drive of a PC. Nor can the Zip drive read/write to the installed base of 3.5-inch, 1.44MB disks. The result: PCs using a Zip drive must also have a standard floppy drive.

SyQuest Technologies has done reasonably well with its proprietary 135MB drive, now a standard product within the professional graphics arts and publishing markets, despite similar limitations.

There is a new kind of drive and media, backed by Imation (formerly the disk products division of 3M), Compaq Computer, O.R. Technology and Matsushita: LS-120 drives (the "LS" stands for laser servo). LS-120 drives can read and write to the older 3.5-inch, 1.44MB disks and the 720-kilobyte, DOS-formatted disks, and, with the right BIOS, are bootable and can function as the a: drive of a PC. The LS-120 disks have a 120MB capacity. Ultimately, the LS-120 can replace the standard 1.44MB floppy drive; they are already shipping with Compaq Deskpro 5133-1200/LS and 5166-2000/LS PCs.

The Zip (100MB capacity) and LS-120 drives are comparably priced: estimated street price of $199 for the Zip, $210 for the LS-120. Media costs are also similar: between $15 and $20. But the LS-120 drive has some key advantages over the Zip drive: compatibility with standard 3.5-inch drives, the ability to boot a PC and initially engineered for internal use. Zip drives were originally designed for external use, although efforts are now under way to make Zip drives bootable. Until then, Iomega must rely on the competitive advantages of greater speed (Zips are twice as fast) and brand awareness.

The market for high-capacity, removable-media drives is dynamic. Iomega has blazed a new trail with the Zip drive, but LS-120 proponents aim to replace existing floppy drive technology, while curbing the market for proprietary drives from Iomega and SyQuest. To replace these drives with LS-120s, broad-based support from drive and media manufacturers is a must. Mitsubishi and Maxell have announced they would make LS-120 drives and media, respectively. In-Stat expects further announcements soon from major drive manufacturers, as well as PC OEMs.



Tape BackUps - Streamers

There are many types of tape backup systems, however you may rely only on one: fabricated by Colorado Memory Systems. (Well, Colorado was acquired by HP several years ago. Since then you may rely on HP too...)
Another aspect, that the rotating head tape drives are fast, but NOT so reliable as streamers.
