It is highly scalable.
It is suitable for both medium-sized and enterprise businesses.
It hasn't broken down anytime in the last six to seven years, despite hurricanes, earthquakes, and power outages.
I rated the scalability as seven because even though the solution can scale, load balancing must be done manually, as it's not automated.
A big banking client had around 300 petabytes of data on Pure Storage.
The solution is highly scalable, particularly when there is a need to expand capacity.
I rate FlashArray's scalability nine out of 10.

Sentiment score
8.3
Pure Storage FlashArray is praised for reliability, minimal downtime, seamless upgrades, and excellent performance under high-demand conditions.
During the eight years, there have been no problems such as hardware failure or stopping.
I would rate the stability of the solution as a ten out of ten.
I would rate the stability of the product at seven out of ten.
For stability, I rate it a ten out of ten.
I have not encountered any significant issues, such as applying firmware that introduces bugs.
Stability has never been an issue except for minor controller glitches causing failover events, similar to brakes and tires on a car.
 

Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Nasuni struggles with cloud integration, performance, and user experience, needing improvements in data retention, security, and analytics.
Pure Storage FlashArray needs scalability, unified management, integrations, enhanced features, cost-effectiveness, and improved performance, analytics, and documentation.
We would appreciate a built-in transparent failover in the next release to eliminate the need for a separate metro cluster.
I'm eagerly anticipating the roadmap's promise of introducing multiple controllers, which could significantly boost scalability and resilience.
We mostly rely on long-term releases. We don't need the most up-to-date features, but we need a reliable environment.
I suggest Nasuni improve their syslog forwarders to support TCP protocol, as it's more secure than UDP, which is plain text and not protected at all.
Integrating object storage into the FlashArray would benefit entry-level and SMB customers by offering a more unified solution.
Storing cold data on expensive arrays doesn't make financial sense, and tiering to any of the big three cloud providers would be advantageous.
As a technical professional, I lack visibility into the system logs.
 

Setup Cost

Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
Nasuni offers competitive pricing with flexible cloud compatibility, licensing per terabyte, and cost-effective enterprise solutions.
Pure Storage FlashArray is costly but offers high value with performance, support, and upgrades, ideal for high-performance needs.
While the prices may be higher than those of other vendors, we see it as a market leader with benefits.
The support can be a bit pricey, but the solution is more cost-effective than anything else out there.
I would give it a nine out of ten in terms of costliness.
I prefer solutions with lower pricing.
They're expensive.
While they say it's free, we actually pay for support upfront.
The cost of Pure FlashArray is a bit high compared to peers, but its sustainability and features justify the price.
 

Valuable Features

Pure FlashArray X NVMe offers exceptional performance, reliability, scalability, and seamless VMware integration, enhancing workload efficiency and user experience.
Nasuni provides scalable cloud-based file management with global file locking, data security, and efficient disaster recovery features.
Pure Storage FlashArray offers impressive data reduction, speed, and ease of use, with strong integration, scalability, and customer support features.
Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator.
The platform's robust features include excellent sustainability tracking, and a comprehensive dashboard offering insights into IOPS, bandwidth, performance, and virtual activities.
Its data compression feature is the best that we have ever seen.
The features I find most valuable in Nasuni are the unlimited snapshots, antivirus capabilities, auditing, and ransomware protection.
FlashArray's integration with the Pure One instrument provides a centralized platform for efficient management of all arrays.
Another noteworthy aspect is their platform, Pure One, a cloud-based analytics platform that automatically creates a case and sends out a part if a disk or controller fails.
It handles internal data migration seamlessly in the background without going offline, achieving a hundred percent uptime.

Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

It helped us save 40 to 45 percent on some types of data
It can provide a 360-degree view of your data, depending on how you implement it and whether you're storing your data in Nasuni. However, if you're working with multiple cloud providers, I don't think it's mature enough to provide a 360-degree view of what's in AWS, Azure, and Google Cloud. I think it can do it, but it's still a lot of scope and range fitting. Given that Nasuni storage is actually cheaper in some areas, it made sense for us to move a lot of our data away from Microsoft. Nasuni gave us more of a 360 view of that particular data type. Other data types are a little different because the company went in a direction where they wanted to store some stuff in an AWS S3 bucket rather than a file storage system. An S3 bucket has its advantages, but if you were to store more of your data in Nasuni, you would get a wider 360-degree view of it rather than on several cloud providers. I have data in AWS, Google, and Azure, and I would like to see a wider view of all the data stored across these three top providers. Currently, I use it for AWS and Azure, but I couldn't use both of them at the same time. I think Nasuni could have better visibility across these different areas. I had to take my data out and then do some analysis to get the costs. It would be helpful to have more built-in analytics tools to compare the storage costs between the various cloud providers. I would also like some graphing capabilities. We had a tool called Grafana that we used for graphing. I think some more visual analytics like that would be nice.

Expands capacity and requires minimal management
The main drawback is the support. I’ve been working for four years without a local representative, and although I’ve submitted many requests, nothing has changed. They sometimes call me in the middle of the night, even though I’ve informed them about my working hours. I often raise cases to speak with someone directly because I prefer to discuss issues over the phone rather than via email. I specifically request them to call me when I open a ticket, but they continually reply by email instead. This ongoing situation has been very frustrating in terms of the support I receive. As a technical professional, I lack visibility into the system logs. Whenever an issue arises, a ticket is opened for us. While I'm glad they take this step, it can be frustrating. They inform me, “Hey, we opened this ticket for you. It’s critical. Call me so we can discuss what’s going on.” However, as a product manager for my institution, I don’t have access to the logs, which are withheld due to, as they say, proprietary code. I understand that, but I have been working in storage for many years and am not new to this field. In fact, I spent 17 years at IBM Storage, dealing with large enterprise systems, not just small vendor products. I wish I could access the normal logs to diagnose issues myself, rather than relying solely on their information. Before I can escalate issues or open a checklist, I need to have a clear understanding of what’s happening based on the logs. Sometimes the situation feels rushed, and I end up having to push my support team for answers. There are moments when I feel like I’m left in the dark about the log details until I actually call them for clarification. It can be quite challenging. Pure Storage can improve FlashArray by providing more logging visibility to customers. Currently, there is no log visibility. They could include an audit log, but I cannot see any system logs when problems occur.
