Buffer - Buffers are holding areas for data shared by devices that operate at different speeds or have different priorities. A buffer allows a device to operate without the delays that other devices might impose.
Form Factor/Type - The physical size of the hardware components in your system. For example, the form factor for an HDD might be 2.5 inches or 3.6 inches.
Interface - An interface is the means by which two independent systems communicate. For HDDs, the interface refers to a connector that plugs your HDD into your computer so it can receive power or data.
SATA - Serial Advanced Technology Attachment. It's a type of interface that connects a storage device 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 or ATA-300) and SATA III (6.0Gb/s or ATA-600).
Spindle speed - The rotational frequency of the hard drive platter, measured in revolutions per minute (RPM). Spindle speed affects how fast the hard drive delivers data.
SATA 6 Gbps with NCQ for interface speed
