Tandberg Data RDX External bare drive, black, S-ATA interface 6010 8426 00 ユーザーズマニュアル

The RDX system is compatible with all common backup applications and will plug-and-play in all 

backup architectures. IT professionals do not need to change designs, complicate backup 

processes, or even add cost to derive the benefits of using RDX backup technology. 

Anyone who has ever configured a multi-disk server can tell you that setup and security are never 

as simple as advertised and can often be quite complex. The RDX device has all of the benefits of 

using a disk drive, with no special setup required. In fact, managing an RDX device with a backup 

application is easier than using a tape device with simple drag and drop icons. 

Like all tape drives, hard disk drives vary in throughput and performance. The advantage that disk 

drives have over tape is the ability to randomly access data once it’s recorded.  Even if data is 

written in a sequential format, RDX can access and read data randomly, which essentially 

eliminates seek time and vastly improves single file restore times.   

RDX has a level of reliability never before seen in tape backup. The life span of a tape drive is 

limited by the magnetic head that is in actual contact with the tape media as it reads and writes 

data. The physical contact causes wear of both the head and the tape, limiting their life and 

eventually resulting in failure of both drive and media. The RDX system has no such direct contact 

and features a much less complex design that is inherently more reliable in its simplicity. This gives 

the RDX drive an expected reliability that is at least 10 times better than that of most tape drives. 

Because of its direct contact with the read/write heads, tape media life is determined by the 

number of uses. While sometimes specified somewhat higher, industry experts agree that a single 

piece of tape media can only safely be used about 50 to 100 times. Depending upon the frequency 

of use, this limits most tape media to less than a single year of reliable usage.  

RDX media is a complete, self-contained HDD and, as such, has a simple connector as its 

interface.  Since the RDX HDD essentially never wears out, the cartridge’s life is limited only by the
