What is a benefit of XtremIO All Flash arrays?

Show Suggested Answer Hide Answer
Suggested Answer: D

XtremIO All Flash arrays provide a significant benefit in terms of cost per I/O per GB when compared to traditional spinning disks. This is due to the higher performance and efficiency of flash storage, which delivers faster data access speeds and better I/O rates. As a result, the cost per I/O operation, when spread over the total capacity of the storage (GB), is lower for all-flash arrays. This efficiency translates into better overall value, especially for workloads that require high I/O throughput1.


It is a common understanding that all-flash arrays, like XtremIO, offer better performance and efficiency compared to spinning disks, which results in a lower cost per I/O per GB1.

The ''Introduction to XtremIO X2 Storage Array'' document from Dell Technologies highlights the efficiency of the storage array, which contributes to reducing the $/GB cost of storage2.

Additional data from industry sources supports the notion that all-flash storage can be more cost-effective in the long run due to operational cost reductions and lower total cost of ownership (TCO) over time1.
