There is a large amount of lifespan variability in actual use. One full file pass is equal to writing enough data to fill an entire tape and takes between 44 and 208 end-to-end passes. Regularly writing only 50% capacity of the tape results in half as many end-to-end tape passes for each scheduled backup, and thereby doubles the tape lifespan.
For example, the highest capacity disk drive listed and plotted for 1981 is 26MB while the actual highest capacity HDD then offered was the IBM 3380 at 2,520 MB per disk drive (2 HDAs per disk drive box). By the late 90s high performance drives were readily available at retail. Tom94022 06:10, 25 March 2009 (UTC)
A tape drive is a data storage device that reads and writes data on a magnetic tape. Magnetic-tape data storage is typically used for offline, archival data storage. Tape media generally has a favorable unit cost and long archival stability. A tape drive provides sequential access storage, unlike a hard disk drive, which provides direct access ...
The T10000E drive was expected in 2017 with capacity in the 12-16 TB range; [9] however, development was cancelled in 2016. Oracle continue to feature the model T10000D on their website for use in select models of StorageTek robotic tape libraries, [ 10 ] but Oracle has adopted LTO-8 tape drives for future capacity expansion on many of their ...
In the case of disk-based media, the primary cost is the moving parts inside the drive. This sets a fixed lower limit, which is why the average selling price for both of the major HDD manufacturers has been US$45–75 since 2007. [15] That said, the price of high-capacity drives has fallen rapidly, and this is indeed an effect of density.

The first 3480 tape drives were introduced in 1984. The IBM 3480 was the first tape drive to employ magnetoresistive (MR) heads and the first to use chromium dioxide tape. One way the format stands out from earlier formats is that the gap between blocks is too small for the drive to stop the tape within it, so the drive must have a write buffer.
Drives may slot into a drive bay of the corresponding size. Compared to flash drives in same form factor, maximum rotating disk drive capacity is much smaller, [citation needed] with 100 TB available in 2018, [1] and 32 TB for 2.5-inch. [2]
