Question 64

Which block storage device protocol achieves the optimal cost-effective balance between I/O performance and high storage capacity for midrange storage applications?

    Correct Answer: D

    Serial Attached SCSI (SAS) is a protocol designed specifically for block storage devices. It achieves an optimal balance between I/O performance and high storage capacity, making it ideal for midrange storage applications. It is more advanced than SATA, providing better performance and reliability while being more cost-effective compared to NVMe and SSDs, which typically have higher performance but also higher costs.

Discussion
WazBlackOption: D

SAS is a block disk protocol that replaced SATA. SAS disk drives are designed for midrange block IO storage applications, balancing performance with higher storage capacity.
