Zadara and Microsoft Storage Spaces Direct compete in the storage solutions category. Based on data comparisons, Zadara seems to have the upper hand due to its advanced features and flexibility, particularly in hybrid and cloud environments.
Features: Zadara integrates with cloud platforms such as Amazon EC2, offers managed services with workload customization, and supports multiple protocols and deployment options. Microsoft Storage Spaces Direct focuses on high-performance on-premises deployments, offers wide hardware compatibility, and excels in hyper-converged environments.
Room for Improvement: Zadara users wish for more proactive updates, improved VMware support, and real-time synchronous replication. Microsoft Storage Spaces Direct needs better documentation, simplified RDMA configurations, and enhanced user accessibility.
Ease of Deployment and Customer Service: Zadara provides seamless hybrid cloud deployment and 24/7 support, facilitating easy integration. Microsoft Storage Spaces Direct has competent support for on-premises setups but lacks the agility of Zadara’s hybrid services.
Pricing and ROI: Zadara's pay-as-you-go model allows cost-effective scalability without upfront costs, aligning expenses with usage. Microsoft Storage Spaces Direct, part of Windows Server, involves higher initial costs but offers cost benefits for long-term on-premises solutions. Zadara’s adaptable pricing contributes to a notable ROI compared to Microsoft's upfront investment.
It does not require much management once you set up correctly, so it saves time, allowing an admin to focus on other work.
While our systems will be out of life in a few years, I believe that in that time, the payback from Microsoft Storage Spaces Direct will save us money on virtualization and storage costs, making it extremely beneficial after six years of use.
I see some ROI in Microsoft Storage Spaces Direct, such as saving time and money, and I estimate these savings to be about 30%.
The cost is not cheaper compared to AWS, and we have not seen the expected return on investment.
I would rate them an eight out of ten.
The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years.
Their technical support has been perfect lately, so I would give it a 10.
There were issues that the Microsoft team could not pinpoint, leading to delays in finding solutions.
Microsoft focuses on Azure as a cloud service.
We lack adequate response times and a 24/7 service level agreement.
I rate the technical support from Zadara as nine out of ten.
Pure Storage FlashBlade is scalable.
There are between 5 and 10,000 people using it in our organization.
The scalability of Microsoft Storage Spaces Direct has been extremely good, allowing for both vertical and horizontal expansion.
It has limitations; it's configured for eight servers per site but can be scaled to 16 servers.
The scalability of Microsoft Storage Spaces Direct is limited.
Zadara is a fully-fledged platform, and our customers are happy with its use.
In case there is any issue with any blade, the data is moved to another.
Microsoft Storage Spaces Direct has been incredibly stable as long as it is configured correctly; incorrect configurations lead to surprises, which is common with any product.
Storage Spaces Direct is stable enough, however, there can be some glitches.
Technical support definitely needs significant improvement.
Its configuration should be easier.
One way Pure Storage FlashBlade can be improved is by having more compatibility between the FlashArray and FlashBlade.
The licensing for Microsoft Storage Spaces Direct could be improved to be clearer, as calculating license requirements requires significant expertise; even Microsoft resources do not provide the full picture needed for licensing, leaving gaps that become evident once we move to deploy solutions.
One year ago, I had a problem, and it was difficult to identify and solve due to a lack of tools.
The performance of Microsoft Storage Spaces Direct is challenging when trying to support both NVMe and SATA SSDs, and there are problems regarding performance that need to be addressed.
Adding AI capabilities could enhance the offering as well.
Maintenance can also be complicated, especially when deeper troubleshooting requires navigating the CLI and searching for logs.
The pricing of Pure Storage FlashBlade is expensive compared to other products I used from other companies in the past, but one benefit is that they have built-in ransomware protection.
Regarding pricing, it is okay; we needed exactly this in size, and the price was a lot lower than competitors, making it good for us.
I find the Azure Local to be a bit expensive, especially due to hidden costs associated with additional tools needed for monitoring and alerting.
Pricing is an advantage of Storage Spaces Direct.
The pricing is considered expensive.
We can plug in many blades, and we can have data up to one terabyte.
The best features of Pure Storage FlashBlade include better throughput and better performance.
Pure Storage FlashBlade's scalability is one of the most valuable features, and importantly, it always works, allowing for seamless upgrades.
The redundancy and fault tolerance features of Microsoft Storage Spaces Direct have helped maintain data integrity and availability in my company by providing multiple copies through three-way mirroring, delivering hardware performance needed for our applications, which is crucial.
For caching, I use disks with more total bits written, which protects the main storage because writes are combined.
The price performance is the best advantage of Microsoft Storage Spaces Direct.
The most valuable feature is its storage management capability.
Zadara's troubleshooting feature is very valuable for me.

Reviews from Real Users
Zadara is a highly effective solution that stands out when compared to many of its competitors. Two major advantages it offers are its extensive suite of cloud solution integrations and its object storage capability.
Steve H., the chief technology officer at Pratum, writes, “One of the most valuable features is its integration with other cloud solutions. We have a presence within Amazon EC2 and we leverage computer instances there. Being able to integrate with computing, both locally within Zadara, as well as with other cloud vendors such as Amazon, is very helpful, while also being able to maintain extremely low latency between those connections.”
Mauro R., the CEO of Momit SRL, says, “The object storage feature is wonderful. With traditional storage, you have a cost per gigabyte that is extremely high or related to the number of disks. With Zadara Storage Cloud, you have a cost per gigabyte that you can cut and tailor to your needs independent of the number or size of the disks.”
