Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."The solution is scalable."
"The initial setup was extremely simple and straightforward."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"It has good, reliable, fast storage."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"We are a 100% satisfied with the stability of the solution."
"The most valuable features in IBM FlashSystem are IOPS, performance, duplication, and compression."
"This solution is really user friendly. It also offers good performance and is highly reliable."
"The Flash core models offer amazing performance."
"The most valuable feature of the solution is replication...Stability-wise, I rate the solution a nine out of ten."
"The performance is very good and we use this product to enhance our core system."
"Stability-wise, this solution is fine."
"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."
"I'd like to see the product implement active replication for vehicles such as VMware."
"In the future, I would like to see integration with enterprise backup systems."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"The tool's portfolio is minimal. It is expensive."
"They could add more support for file storage and different types of storage."
"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."
"The UI for this solution needs to be improved."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"In IBM FlashSystem, data reduction is an area with shortcomings where improvements can be made in the future."
"IBM should improve its data reduction development."
"The price is very costly."
"This solution needs a management console where we are alerted to issues and can report them, or escalate them through email or another method."
"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 ease of installation should be improved. We had issues with the configuration model."
"Product support is restricted to IBM only. It must be decentralized to IBM partners as well."
"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."
"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."
IBM FlashSystem is ranked 6th in All-Flash Storage with 106 reviews while VAST Data is ranked 17th in All-Flash Storage with 2 reviews. IBM FlashSystem is rated 8.2, while VAST Data is rated 10.0.
