SAS vs SSD

Difference between SAS vs SSDSAS is a serial drive interface based on Serial-Attached SCSI. SAS supports both SCSI and ATI. SAS is a performance over traditional SCSI. They are designed for high-performance enterprise purposes. It enables multiple devices of different sizes to connect with longer cables. Those cables can be hot-plugged. It is a point-to-point protocol moves data to and from computer storage devices. SSD is a drive technology like cd, DVD and it is a Solid-state drive (also known as flash drives). SSD data are stored on flash memory chips so the data can be retained without power. Basically, the same type of memory used in SD cards or non-volatile memory in mobile devices.

What is SAS?SAS devices have two ports each resides in a different domain. IN case of failover, if one path fails it takes another independent path for communication. SAS ports fall in Transport and physical layer. SAS has well-defined address/ID unique to each of its drive.

In layman terms, it is a connector that connects the server motherboard with hard drives. They replace traditional SCSI drives. The key attribute is serial interconnect.

What is SSD?First SSD is launched in the year of 1970 for INM supercomputers. SSD refers to a type of internal technology. They are built from silicon memory chip with no moving parts and rotational delay which reduces response time. They deliver end- to- end data integrity and include a function like error correction to improve reliability.
