| Advantages of Tape Drives | | | | organised and this particular process is automated as |
| - In tape drives, it is not possible to access any data | | | | well. The software that is used for the same has |
| randomly but it can be accessed only sequentially. But | | | | also shown a lot of development over the years. |
| even with this apparent disadvantage, high data | | | | - The reliability of storage of data on tape drives has |
| transfer speeds (up to 80 MB per second) can be | | | | been in question many times. But nowadays even |
| achieved on them. The randomness in access of data | | | | that is not a thing to worry about since the tapes |
| is also not required generally as most of the data | | | | keep your data quite safe for a long period of time |
| backup is carried out just to comply with the laws of | | | | though not as long a time as offered by hard disks. |
| disaster management and these data are rarely | | | | But this is amply compensated by the cost |
| accessed in reality except when a disaster strikes. | | | | difference between the two. |
| - Another significant advantage of tape drives is the | | | | - Corruption of data that has been backed up is a |
| amount of storage space that they offer. It ranges | | | | problem that has been faced by many companies so |
| from a few Megabytes to about 800 GB that too | | | | far and the only solution for the same is making |
| without compression. With such a large amount of | | | | multiple copies of the same data. Practicing the same |
| space available, a single tape drive could prove to be | | | | by using disks proves to be very expensive and |
| sufficient for all the data that you may need to | | | | hence a backup copy on a tape is generally |
| backup. | | | | preferred. |
| - To add to the above mentioned capacity, tape | | | | - Where security is the concern, tape drives also |
| drives offer you a high compression ratio, which | | | | have not been left behind and the newer versions |
| means that the data that is to be stored on the | | | | offer options such as WORM (Write Once Read |
| drive can be compressed to even half its original size. | | | | Many) which allow data to be written on the disks |
| - Also, with the technological advancements in the | | | | only once and it can be accessed many times. Other |

| have not been left behind. They have shown a vast | | | | also limit access to the data to a particular |
| amount of improvement over the years since 1951 | | | | geographical location so that the data cannot be |

| - Cost is always an area of prime importance when | | | | The Last Word |
| data backup is concerned. Tape drives are quite cost | | | | The tape drives are also expected to hold a large |
