SAS stands for Statistical Analysis System, and SATA stands for Serial AT Attachment. SAS and SATA are similar interfaces; however, there are some significant differences between the two. Businesses are clamoring for more secure and dependable information storage and need it to be accessible all the time.

SAS gives the power and the reliability of SCSI that is necessary for enterprise-class storage. SAS technology currently delivers a maximum of 3GB/sec speed, whereas SATA's maximum could come to was 12B/sec in the future. SAS devices are compatible with SATA storage systems, which provides a plethora of solutions and system consolidation.

SATA is also more affordable in cost than SAS, which makes it the preferred option available. Parallel interface drives have paved the way for superior serial interfaces, and SAS and SATA have become two different technologies preferred by the industry. SAS interfaces are suitable for enterprise use, while SATA drives are typically rated for less than 100 percent duty cycle. SAS drives maintain all the high performance and consistency of SCSI.

SATA or Serial AT Attachment and SAS or Serial Attached SCSI are two interfaces for hard drives. SATA was designed to improve on some of the limitations of PATA. On the other hand, SAS was released to improve on some of the limitations of SCSI. The difference between SATA and SAS is that they are used differently. SATA is used in recent computers, whereas SAS is an interface commonly used in high-end computers where more data need to be transferred. SAS is not as common as SATA, probably because it is expensive. You can only see SAS in pricier motherboards. However, SATA comes with almost every new computer. Another difference is that both use different commands. SATA still uses the ATA commands of its predecessor, whereas SAS still uses the SCSI commands of its predecessor. While SATA can only use shorter cable, SAS can still work with longer cables.

SATA stands for Serial Advanced Technology Attachment while SAS, on the other hand, stands for Serial Attached SCSI. If you are wondering what SCSI means, this is Small Computer System Interface. They are both drives that are being used by different gadgets right now. One of the main differences that you can find is the speed. Another thing that you will notice about these two is the reliability of these drives. Between the two, SAS is considered to be more reliable as compared to SATA drives. One of the common mistakes of people is assuming that SATA and SAS drives are interchangeable. They have differences that will definitely help you choose which one will work better.
