Detailed explanation-3: -The advantages that come with magnetic storage include permanent storage and flexibility of editing storage files. Hard drives are cheap to make and offer high speed accessibility. The disadvantages for magnetic storage include susceptibility to error and low portability.

Detailed explanation-4: -Susceptible to Physical and Environmental Damage Another disadvantage of magnetic tape as a storage medium is its susceptibility to physical and environmental damage. This may lead to data loss, data alteration, and/or permanent tape damage.

Detailed explanation-5: -One of the biggest disadvantages is that it’s slow. Because data is written to tapes sequentially, it can take a long time to back up large amounts of data.
