The predicted marriage of tape backup with high-performance random access disk technology has 

been floating around the industry since the advent of disk drives. Both industry experts and storage 

vendors alike have predicted that customers will need to be able to choose between tape and disk 

in an attempt to define the ideal secondary storage solution. However, attempts to replace tape 

with various technologies have always failed because they could not match or surpass tape in its 

removal, capacity, archival or low-cost benefits that users demand. The industry has therefore 

been searching for and exploring technologies that both complement and address tape’s biggest 

detractors; its relatively low performance during both backup and retrieval operations, and its’ 

relatively high failure rates when compared to disk.  

This paper explores the benefits of a new portable disk based technology, RDX®, which 

successfully and cost-effectively matches and surpasses tape in all of its key aspects AND 

provides the backup and retrieval performance of random access disk with 99.999% reliability. The 

RDX® QuikStor solution is the only viable removable backup for high-capacity desktops and low-

end servers. 

RDX is a removable hard disk drive system that handles and operates like traditional tape drives 

and media, yet has all of the advantages of disk-to-disk (D2D) systems. The RDX device allows for
