A tiered storage system provides lower total cost of ownership for large volumes of data by storing data on the most appropriate storage tier (flash, disk, or tape). Independent studies have demonstrated that the total cost of ownership with combined disk and tape solutions is 3 to 7 times lower than disk-only solutions [source]. In addition, the failure rate of tape is much lower than disk because the tapes do not contain continuously spinning mechanical parts. While tape storage offers better total cost of ownership for storing large volumes of data for long periods of time, access time to data on tape is significantly higher than to data on disk. This can cause negative user experience which is amplified by standard file systems like NFS and SMB that are not tape aware. Implementing tape awareness in standard file system protocols is not easy because of the wide distribution and acceptance within existing IT solutions. However, newer data interfaces such as object storage APIs can easily be adapted to the characteristics of tape [source]. Consequently, the integration of a tape-aware object storage API for data access in a tiered object storage system has the potential to significantly improve the user experience while lowering total cost of ownership with tapes. This will eventually drive the adoption of the tape tier for cloud storage.
