What technology standard is commonly used today for hard drives?

Solid-state drive (SSD) is the commonly used technology these days for hard drives .It has pretty advantages over hard disk drive(HDD) .
One advantage is ,its speed is unmatchable to HDD and the data is stored in microchips. Unlike HDD,which uses a mechanical arm with a read/write head to move around and read information from the right location on a storage platter ,it collects information directly from microchips .It is simply the oversized version of USB stick .More reliable and sustainable.
