Al Shugart‚ one of them‚ later left Memorex and founded first Shugart Associates where the 5 1/4" floppy disk drive was a major product‚ then Seagate Technology‚ which effectively started today’s industry of small hard disk drives. The early

A solid-state drive is a drive that uses non-volatile memory as a means of storing and accessing data‚ similar to computer RAM (SSD‚ 2014). An advantage the solid-state drive has over other hard drives is no moving parts. This allows the solid-state drive to access information faster‚ produces no sound‚ and significantly more reliable than the common hard drive. The first solid-state drive was designed and implemented between the 1970s and 1980s. Throughout the years‚ the storage capabilities have
