Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Scott Taylor - PeerSpot reviewer
Manages large data sets efficiently with hybrid cloud integration
My organization is quite large, with about 30,000 employees. The growth has been substantial in areas such as radiology and genomics. One of the best features we've utilized recently is offload to cloud pools due to capacity constraints on-premise. We didn't want to expand Dell PowerScale (Isilon) straight away, so we utilized cloud pools to offload some data to Azure. That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.
