Pros
"The most valuable feature is replication.""Pure gives us better compression, it's easier to manage, a lot less hands-on.""Performance, deduplication, compression, and fast response time for requests from servers and applications.""It simplifies building out the storage.""The initial setup was straightforward in the way that it was a database vacuum storage.""It helps to simplify storage. For most of our customers, when they move to Pure Storage, storage becomes an afterthought.""Performance, dedupe, and that it works well with database workloads are its most valuable features.""It is always out of the box, and ready to use."

More Pure Storage FlashArray Pros →

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust.""It provides a combination of all the protocols that you need, without losing deduplication and compression.""Data Compression: Up to 80% space reduction in the database""It performed great originally, and when it performed great, it was awesome.""EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks""It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment.""The initial setup is straightforward.""High performance and ease-of-management are the most valuable features."

More DDN IntelliFlash Pros →

"I would have to say performance at this point, because the application it is based on is so diverse.""The speed is the most valuable feature.""The benefits are better up-time, better response time.""The solution allows us to segregate one storage unit from another.""I like the performance aspect of EF Series. It basically provides everything that we are looking for as a solution, very low latency and very high performance.""The management software is very good.""This storage solution is both stable and scalable, and it works for our needs.""The most valuable feature is the ability to set a specific margin of performance to a specific workload."

Cons
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve.""Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve.""The price could be better.""I would like to have support available in Spanish.""The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser.""In terms of the future, I have been excited by some of the copy data management stuff that they're talking about building into the environment. There are feature sets where I've done a lot of automation work. So, I am always looking forward to extensions of their API. They're also talking about a phone home centralized analytics database being used as a centralized management console with a list of new cloud features, but this doesn't seem finalized.""I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable.""The solution could improve by having a multi-tenant feature."

More Pure Storage FlashArray Cons →

"It only keeps one hour of real-time data without the ability to do deep analysis of each element.""They need to offer better integration for a virtual platform to enable you to create hyper-converged solution.""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.""Snapshots are not as easy to access as on a NetApp device.""It's somewhat scalable, but maybe not so much as some of the competition.""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.""Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible.""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."

More DDN IntelliFlash Cons →

"This solution does not have any compression or deduplication.""I've observed an issue when creating a new storage solution with NetApp EF-Series All Flash Arrays.""It was difficult to implement and lacks some additional features that would be useful, but as a solution fits a particular need for our organization.""A little more manageability, a simpler management interface. It's not necessarily that it's way overly complex. It's just that it's not as easy as the FAS series.""Things like the FlexClones, SnapVault, SnapMirror, all of that. Some of it's available on the EF series, but we like what we have in the FAS system.""Their problems are on the software and the controlling of the storage where they lack segmentation and federation.""The initial setup phase of NetApp EF-Series All Flash Arrays is not straightforward and needs improvement.""We need a center related to NetApp in Egypt so that we can deal with them directly."

    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.

    The NetApp EF560 all-flash array is an all-SSD storage system for applications that demand extremely high levels of performance and reliability. Requiring just 2U of rack space, the EF560 all-flash array combines extreme IOPS, microsecond response times, and up to 12GBps of bandwidth with leading, enterprise-proven availability features.
