SATA, or Serial ATA, is an interface that is used to create a connection between storage devices and the computer system in which they are used. SATA replaced PATA as the most common interface after its introduction in 2000, thanks to thinner connector cables and faster data transfer capacities. With several redesigns over the years, the SATA interface has kept up with changes in storage devices and computer systems. Flash disk SATA is something that OEMs and designers often have questions about. Here are some of the most common questions that arise.

Does SATA work with HDDs and SSDs?

When most people ask about flash disk SATA interfaces, they are really asking for SSDs with SATA interfaces. SSD stands for solid state drive, and it is actually a drive that does not have a moving disk. Instead of having a moving disk, SSDs typically incorporate flash technology, in which program and erase cycles are performed using a series of electronic charges rather than a spinning disk. This makes them more reliable and faster than disk drives.

The question of a disk drive comes into play with HDDs, or hard disk drives. Hard disk drives contain a disk that spins during read and write operations. Although HDDs have huge capacities, they are generally slower than SSDs because the disk has to fire into operation for each action. The disk also means that the drive is more prone to failures. However, both HDDs and SSDs work with SATA interfaces.

What is the data transfer speed of a SATA interface?

The data transfer speeds of SATA interfaces have changed over the years as redesigns have occurred. The most current version of SATA is SATA 3.2. It allows for data transfer speeds of up to 6Gbps and features SATA Express, which allows SATA ports and PCIe—PCI Express—lanes to be used at the same time. Many device designers appreciate that this option allows for more flexibility in their projects. All SATA revisions are backwards compatible, though they will only meet the data transfer speeds that are possible with the older devices.
