Both SAS (Serial Attached SCSI) and NVMe (Non-Volatile Memory Express) are capable enterprise storage technologies. SAS is the older of the two architectures and also tends to be the cheaper option. Conversely, NVMe is the better choice for users who need the highest possible throughput rates.

Conclusion

SAS and NVMe are two different protocols for accessing data on solid state drives (SSDs). SAS is the traditional protocol for connecting SSDs to a computer, while NVMe is a newer protocol that was designed specifically for SSDs. NVMe offers several advantages over SAS, including lower latency, higher bandwidth, and more efficient use of CPU resources.
