Pros
"The most valuable features of Pure Storage FlashArray are the management view of the solutions, ease of provision, and deprovision, it is fantastic.""It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage.""It comes with a large number of features out-of-the-box, which makes it easy for us to see problems and manage capacity.""It is pretty much just plug and play. There is not that much to do with it. It is very easy to use.""The most valuable feature of the Pure Storage Flash Array is the blazing fast monitoring.""On a scale of one to ten, where ten is the most comfortable pricing, I rate the solution a nine out of ten.""I find two features of Pure Storage most valuable. The first is the "safe mode" function, and the second is its simplicity.""The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."

Cons
"We haven't seen ROI yet.""It would be good to have metrics of the box's performance so we can see what it delivers, but currently, I can't see what it's actually doing.""We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help.""The 3PAR SSD arrays that we have are still failing a lot so even though we're under warranty, we still have to get someone out and usually have someone troubleshoot so that usually adds onto the cost. With Pure, we've had a disc fail and we pop it out and you pop it in and it's good to go.""I would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side.""I would like to see them lower the costs.""As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it.""I would rate this solution an eight. To make it a ten it would have to be a little cheaper."

More Pure Storage FlashArray Cons →

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible.""Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months.""They need to offer better integration for a virtual platform to enable you to create hyper-converged solution.""It only keeps one hour of real-time data without the ability to do deep analysis of each element.""In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation.""Snapshots are not as easy to access as on a NetApp device.""We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors.""It's somewhat scalable, but maybe not so much as some of the competition."

More DDN IntelliFlash Cons →

"If the VNX had embedded encryption, that would be great.""There is no easy way to defrag a RAID group. It would be nice to be able to reduce the size of a storage pool if the storage is not needed anymore.""Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones.""Based on our workloads, we see repeatedly in performance reports that the built-in controller (SP) cache of our VNX model is not sufficiently large, resulting in forced cache flushing.""The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible.""The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations.""EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this.""The CLI could be better documented, like with VMAX."

Pricing and Cost Advice
  • "We feel that the pricing is fair and the licensing process was easy for both."
  • "There is always room for negotiation."
  • "The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
  • "It is a more expensive solution, but it is worth it. You are getting what you paid for."
  • "For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
  • "We have seen a reduction in total cost of ownership (TCO)."
  • "It is a cheaper solution."
  • "Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."
  • More Pure Storage FlashArray Pricing and Cost Advice →

  • "I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."
  • "I think we pay around 100 grand per year for three arrays or four arrays."
  • More DDN IntelliFlash Pricing and Cost Advice →

  • "The initial pricing and licensing are reasonable. Yearly EMC is more expensive."
  • "While EMC tends to be on the expensive side, the stability and support of their products are top-notch and I feel are worth the cost."
  • "Make sure you understand how the licensing works and that you are getting the right set of licenses if you need array-to-array replication."
  • "Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
  • "Pricing is somewhat higher, especially in Zambia, perhaps due to the low sales volume."
  • "The initial pricing and licensing are reasonable, the yearly EMC is more expensive"
  • "​Reducing dependency on JavaServer Pages​ (JSP) could improve the administrative overhead.​"

    Overview

    Pure Storage FlashArray is the world’s first enterprise-class storage array that runs exclusively on the nonvolatile memory express (NVMe) protocol for memory access and storage. It represents a totally state-of-the-art type of storage technology. It offers users shared accelerated storage that delivers cutting-edge features in the realms of performance, simplicity, and consolidation. Pure Storage is fresh and modern today and will be for the next decade. Without forklift upgrades or planned downtime, Pure Storage takes the work out of storage ownership and delivers unprecedented customer satisfaction.

    Pure Storage FlashArray is built with simplicity and reliability in mind. The solution can be implemented and optimized in hours, as opposed to other similar solutions that can take days. It has no moving parts, which removes areas where it could potentially be vulnerable to suffering errors. It is highly stable and gives users the ability to manage system shutdowns in a way that  prevents data loss.

    Benefits of Pure Storage FlashArray

    Some of the benefits of using Pure Storage FlashArray include:

    • A much higher level of speed than similar pieces of technology. Pure Storage FlashArray maximizes the speed at which data can be transferred while at the same time minimizing system latencies that might slow the transfer down. Additionally, it offers users quick memory read and data access speeds.

    • A higher bang for your buck in terms of the storage capabilities you get for the money you pay. They are smaller in size than more standard storage technologies, but they offer flash memory, which enables users to store larger amounts of data than the current standard.

    Reviews from Real Users

    Pure Storage FlashArray is a highly effective piece of storage technology which stands out among its competitors for a number of reasons. Two major ones are its overall robustness and the value that it offers by way of its reliability and ease of use. It provides users with many valuable features that allow them to maximize what they can do with this solution. Pure Storage FlashArray’s reliability and ease of use make it a highly valuable solution. 

    PeerSpot user Prabakaran K., a technical consultant at Injazat Data Systems, notes the robustness of this solution when he writes, "FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."

    PeerSpot user Jason D., a cloud solutions architect at a tech services company, notes three features that make this solution valuable when he writes, "We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."

    Western Digital through its IntelliFlash arrays delivers high-performance storage with a complete range of features and connectivity options, including inline compression and deduplication, application and VM consistent snapshots, replication, RAID, data encryption, VMware vCenter integration, and multi-protocol support for SAN (FC, iSCSI) and NAS (NFS, SMBv3). IntelliFlash arrays deliver high availability through dualredundant and hot-swappable components, active/active or active/passive controllers, non-disruptive software upgrades, eMLC flash, and proactive cloud-based monitoring, analytics, and intelligence. A RESTful API provides scripted or programmatic control.

    With EMC VNX you'll have the right blend of flash, capacity, and application-aware software. Scale up storage for midrange workloads, optimized for virtual applications and cloud environments.
