SAS or NVMe: Which One is Better and Why?

While Choosing between NVMe or SAS: What are the Points to Consider

NVMe stands for Non-Volatile Memory Express. It is basically an interface protocol that enables us to move data to and from SSD drives with the help of PCI express. NVMe is only purposefully and exclusively created for the SSD drives to make the NAS storage appliance offer more speed.

NVMe is likely to replace and overtake the older storage devices like SATA and SAS due to multiple reasons. One of the reasons is that it offers more storage to the SSD’s used in computers. NVMe is actually an improved version or alternative for the traditional storage interfaces (HDD) which has its related drives SATA and SAS.

NVMe Offers Greater Speed

There has been a trend that wherever larger amounts of data needed to be stored, slower storage appliances were used having SATA and SAS. It is a more recent practice to use high-speed storage appliances for big data as well. This is where the modern NVMe interface featured storage drives are used in the number.

Rapid storage enables the Scale-Out NAS storage appliance to work faster and deliver the results faster than the older storage appliances. This makes the system more agile and efficient.

You Get More Bandwidth in NVMe

Another advantage of NVMe is the bandwidth factor. In comparison to SATA’s 6Gbps and 600 Mbps and where SAS offers 12 Gbps & 8Gbps throughput, NVMe makes a huge difference by offering 16 Gbps in a configuration that has 16 lane structure. In other words, it is also called circa 1 Gbps per lane.

This is the main reason which is making the NVMe a king of speed in the data storage race track. This is the reason why NVMe is winning the pole position in the industry. It is achieved due to the fact that these SSD cards are made solely for the NVMe which makes them store and access data faster as compared to the time that was taken by the storage appliances in the past.

Speed has become one of the most decisive factor among the SAN storage, which enables enterprises to make their decision in favor of faster ones, and against the slower alternatives.

Conclusion

NVMe based SSD drives are surely more preferable storage drives options as they make the storage appliance offer more bandwidth and high speed for the data storage tasks to be performed. Speed is the key element in the modern data storage industry, makes NVMe protocol and SSD drive a winning combination for the enterprises which require speed and want to spend the least amount of time in data accessibility and retrieving processes.
