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.

I thought the benefit was more about performance than cost, but I guess if the cost per I/O is lower, that could be a big advantage too.

Okay, let's see. The question is asking about the benefits of XtremIO, so I'm guessing the answer has to do with the cost or performance advantages of this specific all-flash array. I'll eliminate the options that don't seem to fit and try to narrow it down.

Hmm, I'm a bit unsure about this. I know that all-flash arrays are generally more expensive than spinning disk, but I can't remember if the cost per GB or cost per I/O per GB is the main difference. I'll have to think this through carefully.
