The slower retrieval speed when compared to that of a
fixed disk is also a problem for some users (e.g., 240 milliseconds is a fast access time for CD-ROM).
Nearline storage libraries are redundant by design and less costly per MB than
fixed disk solutions.
Sometimes, it is almost like the
fixed disk bigots (trying to wipe out tape) are beginning to sound like the "optical bigots of old."
Models are available with a range of storage capacities from either
fixed disks or hot-swappable removable drives.
After installation, the system does a one-time scan of the
fixed disks to build up its checksum list.
Different versions have different features, view system memory in different ways and format
fixed disks differently.
