SAS Hard Disk Drives Market Introduction
In a SAS Hard Disk Drives, SAS refers to the interface and is used to transfer data to and from hard disk drives. SAS stands for Serial Attached SCSI. The market for the SAS hard disk drives increased significantly in the last decade after it became evident that it became very difficult to improve upon data transfer speeds based on Parallel SCSI interface.
The unparalleled increasing demand to store data is undisputable. The need to store data spans different applications and environments — each with their own unique requirements. Thus, with continuously developing requirements of the end-users, there is a constant demand for HDD products featuring higher storage capacity as well as performance.
SAS Hard Disk Drives Market- Competitive Landscape
In January 2019, Toshiba Corporation announced industry’s first hard drive featuring a 16 TB capacity. It features a 512 MB DRAM buffer, 7200 RPM spindle speed, and a SAS 12 Gbps interface or SATA 6 Gbps (on the basis of model)

Improved Reliability, Performance, and Cost Driving Demand for SAS Hard Disk Drives
As compared to SATA, SAS drives are designed with more robust mechanical components which aids them to operate for a longer time without failure. Also, they are less susceptible to rotational vibration. Furthermore, only SAS supports validation from the host to physical storage media. Additionally, only SAS supports full SCSI command set, full duplex I/O, and dual path connectivity. Owing to these features, the data can be transferred quickly and accurately.
Also, on the basis of performance, SAS hard disk drives complete read and write task quickly as compared to SATA, owing to faster rotational speed and more precise read/write mechanism. Moreover, on the basis of cost, SAS is reasonable if we consider total cost of ownership and overall cost
