Since magnetic tape does not require power when it is stored, it is a data storage medium that requires a very low running cost when considering the cost of electricity, the cost of air conditioners, and equipment costs at a power facility.
In addition, since its unit price per capacity is lower than that of hard disks, the higher the number of cartridges is, the lower the unit price of the entire system will be.
Secure and Safe
Data loss/leakage accidents due to blackouts, hacking, or theft, etc. occur all around the world. Magnetic tape, which stores data offline, is a data storage medium that has a lower risk of these accidents and is also optimal as a measure for BCP.
It is also suitable for remote storage to protect important data from disasters and other risks, because it allows offline storage and is portable.
Optimal for Long-term Storage
While the life of a hard disk is said to be about several years, magnetic tape has been proven in an accelerated evaluation test to maintain its performance for over 30 years.
In addition, since magnetic tape has lower failure and error rates and higher reliability than hard disks, it is appreciated to be the best data storage medium for long-term storage.
Compared to hard disks whose recording density has almost reached the limit, the recording density of magnetic tape is still increasing, and next-generation technologies have been demonstrated. In addition, the recording area can be expanded by making the tape thinner and longer, so further increases in capacity can be expected. Up to LTO12 has already been presented in the future roadmap, which has the highest capacity per cartridge among existing magnetic tape products.
Magnetic Tape Has Achieved a Recording Density Equivalent to 220 TB per Cartridge
