Executive SummaryUpdated on Jun 3, 2026

Everpure Storage FlashArray and Kaminario K2 [EOL] are competing storage solutions focusing on high performance, reliability, and scalability. Everpure Storage FlashArray has the upper hand due to superior features, strong customer satisfaction, and the active support it provides, which sets it apart from Kaminario K2's end-of-life status.

Features: Everpure Storage FlashArray is recognized for its high availability, robust data protection, and simplified management, significantly enhancing performance. It also offers advanced data reduction capabilities, allowing organizations to expand capacity without increasing their physical footprint. Kaminario K2, while offering flexible scalability and efficient data reduction, may no longer meet emerging enterprise needs given its end-of-life status.

Room for Improvement: Everpure could improve by expanding its training programs to enhance initial user onboarding and understanding. Some users express a need for more detailed analytics to drive predictive maintenance efficiently. The interface could potentially incorporate more customization options to fit specific user workflows. Kaminario K2 needs to address ongoing customer support, provide software updates, and ensure future viability as hardware becomes obsolete due to its EOL status. It also lacks advanced intelligence features that some modern storage solutions now include and could benefit from enhancing its data protection services.

Ease of Deployment and Customer Service: Everpure Storage FlashArray is well-regarded for straightforward deployment processes and excellent customer support, which helps customers integrate the solution seamlessly into their existing IT infrastructure. Therefore, it offers a robust service experience with high reliability. Kaminario K2 provides an intuitive deployment model; however, it suffers from lacking ongoing support due to its end-of-life phase, which can hinder future problem-solving effectiveness.

Pricing and ROI: Everpure Storage FlashArray delivers significant ROI as it balances competitive pricing with efficient storage features and continuous updates. Although initial setup might come at a higher upfront cost, its long-term benefits of ongoing enhancements and updates justify the expenditure. Kaminario K2 might present lower initial costs, but the absence of updates and a support framework substantially diminishes its long-term ROI value. Thus, Everpure is better positioned as a sustainable investment.

Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades

The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

A solution with a simple configuration and good stability but it's quite expensive

Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"I am satisfied with this solution, and we plan to keep using this solution."

"This solution has helped my organization by cutting down on provisioning time. I used to have to provision a VM and it would take ten minutes. Now, it takes thirty seconds."

"Very stable; no worries about how much it can handle."

"This was our first all-flash storage enclosure, so we saw huge boost in performance for all of our servers."

"The most valuable feature of Pure Storage FlashArray is the complete set of functions it provides."

"Pure Storage is seen as a visionary company with leading edge technology."

"The most valuable feature is it never goes down. We can expand and create volumes."

"They have really good baked in analytics to show you trends for growth history, so it does help with future planning for data growth."

More Everpure FlashArray pros

"Image backups of our production servers that used to take hours now take minutes."

"The stability of the solution is very good."

"Latency is definitely the big key for us."

"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."

"Looking at what changed at Kaminario the last couple of months (and the last couple of years, for that matter) I’m certain we’ll see a lot of great innovation from Kaminario in their upcoming releases."

"Our holdup was disk I/O, so we did a PoC with Kaminario and we reduced build times down to fifteen minutes for a full build from two hours."

"Logic/software management"

"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."

More Kaminario K2 [EOL] pros

Cons

"More cloud connectivity would enhance the solution."

"We would like to be able to connect to data tape for backup, specifically to the LTO backups."

"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter."

"In terms of improvement, Everpure FlashArray could have more attractive UI/UX design compared to other solutions."

"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."

"The solution needs an integrated NAS platform, file platform."

"When creating a support case, visibility should be extended to others involved in assisting."

"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."

More Everpure FlashArray cons

"The interface look and feel could be improved."

"Replication and de-duplication could be better."

"I would love to see capacity on its DRAM. I know it's not cost effective for them to do it, but I think that it could be a big differentiator and was a big differentiator from the beginning."

"I think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."

"The management graphical interface needs more improvement."

"What I think would be a great idea for Kaminario is more visibility outside the US, when my customers start talking about AFA I notice they almost never talk about Kaminario, mainly because they just don’t know about them, and there are no local sales team to tell them about the Kaminario offering."

"I'd give it a perfect rating if I could push it to 300,000 IOPS like they promote; we just haven't been able to push that many IOPS out of our system."

"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."

More Kaminario K2 [EOL] cons

Pricing and Cost Advice

"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."

"Cost-wise, it's been very effective."

"The price of the solution is not expensive."

"The best features come included without any additional cost."

"The cost has room for improvement."

"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."

"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."

"The pricing is very attractive and it delivers performance for the money."

More Everpure FlashArray pricing and cost advice

"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."

"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."

"The licensing is all-inclusive."

"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."

"Licensing is very straightforward. The cost was considerably lower than other products we looked at."

"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."

"Kaminario is very competitive on price. They also have a pay per TB model."
