HP DAT 160 SCSI External Tape Drive Q1574A#AC3 产品宣传页

Executive summary 

DAT tape technology is the most prolific of all tape technologies with over 15 million drives shipped 

since the first products were introduced in 1989 and more than 6 million since 2000. This gives rise 

to a conservative estimate of a 6-million user installed base. The latest edition to the DAT family is the 

HP StorageWorks DAT160 tape drive, launched by HP in June 2007. The DAT160 drive is an 

evolution of existing DAT technology and has much in common with the previous five generations of 
DAT. Since differences do exist, this white paper answers the top ten technical questions on the 

DAT160 drive.

achieved? 

2. 

How much further can DAT capacities grow? 

3. 

The DAT160 drive has a much high transfer rate. How was that achieved? 

4. 

The backwards compatibility with HP StorageWorks DAT72 and DAT40 tape drives is really 

important to customers. Can you explain how this works? 

5. 

What is the new technology in the DAT160 drive and what has been leveraged from the DAT72 
drive? 

6. 

What have been the key time investments in developing this new product? 

7. 

What is the reliability specification of the DAT160 drive? 

8. 

The DAT160 drive will have a SAS interface as well as USB and SCSI. Why is that required? 

9. 

Is the DAT160 drive suitable for an office environment?  

10. 

What is next in the DAT roadmap? 

The answers to each of these questions with supporting technical explanations and data form the 

basis of this white paper.
