Tape storage compared to disk storage

Tape storage has an advantage over capacity, storage time, and price compared to disk storage. According to statistics, 80% of global digital information is stored on removable storage media, mainly tape, followed by disk. In the future, tapes are expected to continue to increase capacity faster than disks, thus opening up the price/performance difference with disks. After more than 50 years of continuous development and accumulation, tape technology has become mature and reliable, especially as users have more and more data to save for a long time, making tapes more advantageous than large disks in terms of large data storage.
In addition, the data stored on the tape can be stored for 30 years, while the hard disk is electronic. Make a hypothesis, if you save the data on the disk first, put it on for five years without power, wait until the time to power up, then you may not be able to read any data, because the electronic components are aging, so even if there are many Enterprises use low-cost NL-SAS/SATA disks as backup storage devices for data, but more enterprise users still need to use tape as a backup and historical data storage medium to achieve long-term data retention. Therefore, the greater space for tape storage technology lies in the storage of fixed content (so-called fixed content, which refers to data that does not change after writing), data archiving, and compliance applications.
