Line 5:

While sequential access memory is read in sequence, accesses can still be made to arbitrary locations by "seeking" to the requested ___location. This operation, however, is often relatively inefficient (see [[seek time]], [[rotational delay]]).

Magnetic sequential access memory is typically used for [[secondary storage]] in general-purpose computers due to their higher density at lower cost compared to RAM, as well as resistance to wear and [[non-volatility]]. Examples of SAM devices still in use include [[hard disk]]s, [[CD-ROM]]s and [[magnetic tape]]s. Historically, [[drum memory]] has also been used.
