We performed a comparison between Dell XtremIO and VAST Data based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"The latency is good."
"The most valuable feature of this solution is its ease of use."
"It has benefited my organization because it has reduced time to insights."
"The solution is very straightforward to set up."
"Overall stability is very good. It is a very stable solution."
"Very good IOPS performance"
"It has very good performance for an application which needs lower latency and a better response, for example, in microseconds."
"The speed is extremely valuable."
"Initially, we faced numerous issues with our analytical systems. However, we saw performance improvement after the implementation of the solution."
"The performance is good, which is important."
"The solution's most valuable features are the inline data reduction and deduplication."
"Linear performance – The XtremIO wasn’t the fastest in all tests against other all flash arrays, but even with a massive workload, the response time and user experience were absolutely predictable with no sharp drop-offs."
"We've seen great enhancements from the performance point of view. There's good availability, stability, and continuity, but the performance actually has increased by 60 or 70%."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"In the future, I would like to see integration with enterprise backup systems."
"The tool's portfolio is minimal. It is expensive."
"They could add more support for file storage and different types of storage."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"There is room for improvement in the pricing of the product."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"The solution needs to be simplified. When you integrate your storage with other systems, could use a little bit of automation."
"Management and reporting need improvement."
"I am not too impressed with XtremeIO because we had a major failure."
"Get rid of the Java aspect of the GUI console."
"The management should be improved and the GUI interface could be better and easier."
"I would like to see more scalability."
"The product could be improved by reducing the pricing and having better organization in their technical support team."
"I believe having more replication options comparatively to VMAX (other than RecoverPoint) would be great."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
"The write performance could be improved because it is less than half of the read performance."
