Comparing 2.5” SATA II to Other SATA Versions

DE2TAPX7R-35000-2 - SATA - 2.5" SSD - 2TB - MLC

 

SATA SSDs have long been popular solutions for industrial applications. The 2.5” SATA II is one of multiple versions of the interface on the market. In the industrial grade format, the 2.5” SATA interface features SLC NAND flash technology in order to operate in rugged conditions with extreme temperatures as well as high levels of shock and vibration. How does 2.5” SATA II compare with other versions of the SATA interface? Here is a closer look.

 

SATA I

SATA I was the first version of the SATA interface. The first generation of SATA is also known as SATA 1.5Gb/s, as it runs at 1.5Gb/s. The interface supports a bandwidth throughput of up to 150MB/s. As with all versions of SATA, this first generation was introduced by the Serial ATA International Organization, or SATA-IO, which releases the compatibility design specifications that manufacturers must follow. This version of SATA was released in January of 2003, and does not support Native Command Queuing, or NCQ.

 

SATA II

SATA II, or SATA 2.0, was introduced in April of 2004. It was the first version of SATA to support NCQ and is backwards compatible with SATA I. This second generation design runs at 3Gb/s and supports bandwidth throughputs of up to 300MB/s. The 2.5” SATA II design is often used in industrial devices that were designed for use with an HDD but are now transitioning to an SSD. These devices have the space for a full size SATA interface.

 

SATA III

SATA III, or SATA 3.0, was presented in July of 2008. It features faster performance at 6Gb/s with bandwidth throughput rates of 600MB/s. It is backwards compatible with other SATA interfaces, but the speed may be constrained by the capability of the base port.
