Dell EMC Associate – Information Storage and Management v5 — Question 54

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

Answer options

• A. SATA
• B. NVMe
• C. SSD
• D. SAS

Correct answer: D

Explanation

SAS (Serial Attached SCSI) is designed to offer a good mix of performance and capacity, making it ideal for midrange storage applications. SATA is generally more cost-effective but lacks the I/O performance of SAS. NVMe provides high performance but is often more expensive and not typically used for midrange applications. SSDs, while fast, may not provide the same balance of cost and capacity as SAS.
