Ease of use
Companies will measure removable disk media's ease of use in two ways: how it works with their backup software and how easy the removable disk cartridge is to manage. EMC Corp. and Symantec Corp. don't support removable disk drives with their respective NetWorker and Veritas NetBackup products. However, EMC's Retrospect and Symantec's Backup Exec backup products, which are designed specifically for SMBs, do support removable disk drive products.

Because of the limited backup app support, most removable disk drives are bundled with a backup app. For example, Imation's Odyssey Removable Hard Disk Storage System includes EMC's Retrospect backup software. Other vendors also bundle backup apps such as CA BrightStor ARCserve, Idealstor's own Ibac, Symantec Backup Exec QS and Yosemite Backup.

Disk is easier to manage than tape, and there are more options to store and retrieve data with removable disk cartridges. For example, users can treat a removable disk cartridge like an external drive and write and read data from it. And if data is backed up in a native format, it can be recovered without having to go through the backup software interface.

To support removable disk cartridges, tape library vendors must retrofit their products in three ways: the library's bay must accommodate the removable disk cartridge drive; the library's firmware must be upgraded to support the removable disks; and the tape library may need to

support partitioning to maintain LTO tape and disk cartridges in the same tape library.

Spectra Logic's RXT Media is the only removable disk cartridge currently available for use in a tape library. However, it operates only in Spectra Logic's Spectra T950 tape library and, with a list price per cartridge of $1,600 to $7,000 (depending on the number of disks), it's at the high end of the acceptable price range for most companies.
