Compared to magnetic storage devices,  data in optical devices is stored as microscopic dark and light spots and not vulnerable to magnets, dust , humidity and scratches.  However, Optical devices lack adequate for longevity tests, requires distinctive devices to read and used in the formats of DVD-R, CD-R and DB-R only. Solids-State Storage devices uses flash memory and are compatible with SAS and SATA (Hilbert & Lopez, 2011). These devices are durable, have a faster transfer rate as they lack spin-up. The launch times are much faster than magnetic storage devices. However, they are vulnerable data loss as a result of magnetic fields, power loss and static charges.
