Both SATA and SAS interfaces are two commonly used interfaces for SSD.
But, which one is more popular?
At present, SATA SSDs are popular because of their cost-effectiveness.
However, their attach rate is going to decline since the software requirements have surpassed the performance capabilities.
SATA, SAS and NVMeTM are three commonly used interfaces that are used to connect SSDs to servers.
The first two interfaces are using the ATA andSCSIcommand sets respectively.
As thehard drive interfaces, the two technologies are mature.
NVMe is a new emerged command set which operates over a PCIe bus.
It is specially designed for flash-based SSDs and the next-generation volatile memory.
This interface has a streamlined interface and much higher performance.
SATA VS. SAS!
The biggest reason is that there are no future developments planned on its roadmap.
It can easily replace the enterprise SATA SSD.
The vSAS SSD features a sweet spot between enterprise SATA SSD and enterprise SAS SSD.
It offers users with faster performance, larger capacities, and higher reliability, manageability & data security.
On the other hand, the price of the vSAS SSD can compete favorably with SATA SSD.
When transferring data, SATA is only using half-duplex and uses just one lane/one direction at a time.
But, SAS is full-duplex.
That means vSAS SSDs have much faster data transfer speed.
SATA was previously located as a lower-cost interface featuring for consumer-grade hard drives.
While SAS was designed for better infrastructure and drive management capabilities.
It has more robust enterprise deployments along with large topologies.
Besides, SAS has more features than SATA.
For example, it has multiple levels of data security and encryption.
It supports error recovery and error reporting.
The capacity of value SAS SSD is also large that is twice than most available enterprise SATA SSDs today.

SATA SSD or SAS SSD, or Both?
When deploying SATA SSDs within a server, the I/O commands must traverse through a software stack.
But, value SAS uses native SAS from end-to-end.
Thus, it doesnt need any protocol translation so as to improve the performance of SSD.
Currently, the majority of server shipments contain either a SAS HBA or RAID card.
Then, both SATA SSD and SAS SSD can be used in the same drive bay.
So, it is very easy to replace a SATA SSD with a SAS SSD.
Bottom Line
The result shows that SAS SSDs have advanced performance and appropriate price.
More and more IT managers prefer to use them to deal with their center data.
