The iMac Late 2013 has a faster storage speed than most medium processor core personal computers that have been available for around the same time as it. This Apple desktop computer has a Flash storage medium, whereas most computers of this age and spec have an HDD storage medium. Flash Drives store information in transistors on a circuit board rather than on optical or magnetic media. This has the advantage of being much faster than a traditional HDD drive. PCs of a comparable spec and age to the iMac Late 2013 storage media range from HDD to SSD.
