Form Factor/Type - The physical size of the hardware components in your system. For example, the form factor for an SSD might be 2.5 inches or 1.8 inches, which tells you the dimensions of the SSD.
Interface - An interface is the means by which two independent systems communicate. For SSDs, the interface refers to a connector that plugs your SSD into your computer so it can receive power or data.
Read - In computer terms, a "read" refers to accessing a piece of data from a storage device or memory.
SATA - Serial Advanced Technology Attachment. It's a type of interface that connects a storage device or optical drive to your computer's motherboard—think of it like an umbilical cord because it allows data to flow between the two. SATA is measured by how fast data transfers to/from the device. There are three SATA speeds, SATA I (1.5Gb/s), SATA II (3.0Gb/s) and SATA III (6.0Gb/s).
Write - In computer terms, "write" refers to how quickly a piece of data can be saved to a storage device (saving a document is an example of a write function).
