How to measure the speed of SATA devices from the command line on Linux

SATA is the most common bus interface on desktops and on many servers, so it’s important that you know some basic concepts about it Serial ATA (SATA) is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives and optical drives. Serial ATA replaces the older AT Attachment standard (ATA; later referred to as Parallel ATA or PATA), offering several advantages over the older interface: reduced cable size and cost (seven conductors instead of 40), native hot swapping, faster data transfer through higher signalling rates, and more efficient transfer through an (optional) I/O queuing protocol. In short they are usually referred as: SATA revision 1.0 – 1.5 Gbit/s – 150 MB/s SATA revision 2.0 – 3 Gbit/s – 300 MB/s SATA revision 3.0 – 6 Gbit/s – 600 MB/s So which revision are you using on your computer ?
