What are the advantages of all-flash storage over other types of storage?


What are some major benefits of all-flash storage arrays? Why should companies invest in all-flash as opposed to a different storage solution?

Speed (IOPs), increased reliability, compactness.


If your application does not needs those you can go with legacy solutions as far as price justifies.


Sooner or later even price will be in favour of all-flash

Thanks for your input @EGonzalez. What types of storage solutions would you suggest if all-flash is too expensive?

We can use Cache tiers with flash disks in part storage pool creation. So that we can get better performance may be not reaches All-flash but better than SAS drives

In general, all-flash arrays have much better price/performance (in case if turning on DECO is not slowing down the array - some vendors have this issue, so PoC is needed) than hdd-only or hybrid arrays. Higher performance, lower power consumption per TB. The support cost for the HDD-only and hybrid arrays will be more an more expensive, as the HDDs share is going lower, and the main R&D is moved to all-flash arrays. Of course, in some cases (i.e. video surveillance, D2D and maybe several others), HDD-only arrays are the better option, so it's better to make a decision case-by-case.

All-flash arrays are more costlier than any other storage arrays. Will give more performance with less latency when compared to any other arrays

@Krishnamohan Velpuri Do the benefits of performance with less latency justify the cost of all-flash?

@Rony_Sklar Of course, its costly. If performance required.
More money = more performance  as of now. May be in future we may get for less price.
It depends, if customer can bare and if they defiantly need less latency for there applications.
