We performed a comparison between IBM FlashSystem 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."NVMe data storage platform that's easy to set up and easy to use. It's stable, with a lower response time, and quick technical support."
"One of the lesser sung advantages was when we started running our interface engine on Pure Storage. The ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."
"It is the SAN backbone for our company."
"The deduplication and compression meet all of our system requirements."
"This solution is very scalable."
"The amount of data that I have moved to it from legacy storage has enabled us to retire units that are three or four times the physical size."
"The stability is perfect. The reliability is 100% and the latency is always lower than 1 millisecond."
"What I like most about this solution, is the speed, resiliency and scalability."
"The most valuable feature is that is supports a high IOPS rate."
"Over the years, it has become increasingly user-friendly."
"The storage system is one of the best in the world."
"The valuable features are high availability, compression, and a failover mechanism. It's a very highly available storage solution."
"This solution is very stable."
"No queuing and high ops, speed, and performance."
"IBM's technical support do excellent work."
"The maintenance service and support from IBM is very good."
"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."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"I would like to have support available in Spanish."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"We have not seen a reduction in our TCO nor have we seen ROI."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in. They should be clear on the way the controller replacements happen, as it is important to know whether or not you can get a good return on them, because it can be a little confusing."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"There are many features which need to be added, particularly on the replication side."
"The pricing needs to be more competitive."
"The deduplication and compression ratio is not very good. It's not reaching a very high ratio."
"The interface could improve in IBM FlashSystem."
"IBM could do more marketing and improve brand awareness. I had never heard of this product until a colleague told me about it. FlashSystem could add a few features, but it would probably increase the price. For example, Pure Storage offers instant snapshotting and partitioning. That would be nice to have, but I think the cost would go up."
"The solution is not easy to implement. It takes a lot of time to study the product and it's a little complicated in general."
"The Data Reduction Pools (DRP) support could be better."
"The installation is not easy. You need to have extensive knowledge to handle it."
"The array level RAID does not seem available."
"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."
