Software RAID vs Hardware RAID: Which to Choose

At that time, one such gadget could replace 63,000 punched cards, and users gained access to the data in a split second. Modern hard disk drives — HDDs, hard drives, HDDs — are much smaller in size and their capacity has increased a million times. But the physics have not changed: they still have the same set of disk plates with a ferromagnetic layer and an electromechanical drive with a block of reading heads. The solid state drive invaded the mass consumer market in 2009. It has a fundamentally new organization, and it looks like a set of flash memory chips under the control of a built-in controller.
