Are solid state drives common?

Solid state drives (SSDS) are classified into SATA, PCI-E, LIF, and mSATA interfaces
And the current desktop hard disk and laptop hard disk is basically SATA interface.
Solid state drives (SSDS) are generally 2.5 "in size, as are hard drives in laptops and portable drives, and desktop drives are generally 3.5" in size.
So if you have a laptop with a 2.5-inch SATA SSD interface, it's universal;
On the desktop, if you want to use a SATA port on a solid-state drive, you need to add a 3.5-inch drive bracket.
To sum up, solid-state disk pay attention to the interface and size problems, the choice of the basic can be understood as universal.
Within a certain range, it's universal. For example, SATA interface, there are several on the computer, which can be used at will. But for faster solid-state disks (300MB/S or more), the SATA2 is not as fast as the SATA3.
There are also non-universal cases, for example, chassis slots, 3.5 "disk is more, but solid state disk is 2.5"
There is also the case that the interface is not universal, that is, the card solid state drive, there are two main interfaces at present:
mSATA and M.2(also known as NGFF)
These two can only interface, to plug in, not universal.
