If you’re concerned about data integrity, it shouldn’t be news to you to back up regularly. As hard drives get larger and larger, we have more to lose if something goes wrong. Archiving is usually important in any business setting or for people heavily into document-management systems. Your PC’s data is worth a lot more than the PC itself. Spend a bit more money to protect the data with removable storage, a simple backup scheme, and a decent electric power protection. Together they don’t cost much, and they add up to data insurance. The simplest mechanism for ensuring sustained operations is to increase the ease of reproducibility. This is the reason that backups are done.

Removable Storage

Capacity

Super-floppy drives use high-density magnetic media and an enhanced read/write head design to increase disk capacity. These drives do double duty. They read and write not only super-floppy disks, but also common 1.44MB floppy disks, examples of these are Imation’s 120MB SuperDisk (formerly the LS-120) or Sony’s 250MBHiFD drive.

If you are being selective and want to archive up to 650MB of files, CD-Recordable (CD-R) and Cd-Rewritable (CD-RW) drives are a great option. CD-Rewritable (CD-RW) is another useful medium for storing up to 650MB of data. These drives allow you to overwrite data previously written to a disc, so the disks are “recyclable” you can use packet-writing software to drag and drop files to CD-RW discs or convention premastering software to write sessions to your discs, so the medium is a fairly flexible one to use.

For archiving larger files, high-capacity cartridge drives, such as the Jaz and Jaz2, offer 1GFB and 2GB ...
