I would hazard a guess that storing tapes takes up significantly less physical space than hard drives.
I don't think hard drive based storage and tape bases storage have quite the same use case.
- dagw 3y agoI would hazard a guess that storing tapes takes up significantly less physical space than hard drives. An 18TB tape is basically the same size as an 18TB 3.5" hard drive.
- adrian_b 3y agoI doubt that this can be true. I am using older LTO-7 cartridges, with a raw capacity of 6 TB. The newer LTO cartridges must be compatible mechanically with the old cartridges, because the same drive must be able to read and write them. The LTO cartridges are smaller than 3.5" drives, they have maybe about 2/3 of the volume of a 3.5" HDD. Moreover, a tape cartridge is many times lighter than a HDD. I have suitcases with 20 tape cartridges that are as convenient to carry as any typical suitcase. A luggage carrying 20 HDDs would have a very noticeable weight, and its volume would be great not only due to the bigger HDDs, but it would require serious padding to avoid HDD destruction if the case were dropped accidentally.
- dagw 3y agoOK, you made me do the math. LTO tapes are 225 cm^3 and 3.5" HDDs are 245 cm^3 so I stand corrected. The weight point is a really good one as well as a HDD is 3 times the weight of a tape.
