Flexible, Hassle-Free Storage with Seamless Integration
Reviewed on Nov 21, 2025
Review provided by G2
What do you like best about the product?
What I appreciate most about Zadara zStorage is its remarkable flexibility and ability to adapt to nearly any storage requirement. It accommodates block, file, and object storage across a variety of protocols, allowing it to integrate smoothly into different environments without necessitating significant changes. Another major advantage is the OpEx, pay-as-you-go model, which eliminates the burden of large upfront investments and enables you to scale capacity only when it’s truly needed. I also value how straightforward it is to manage; the fully managed 24/7 service means I don’t have to deal with the typical hassles of storage maintenance. Whether deployed on-premises, in the cloud, or at the edge, it consistently provides reliable performance, making it an excellent choice for organizations seeking enterprise-grade storage without unnecessary complexity.
What do you dislike about the product?
There are not many significant drawbacks, but a few aspects are worth mentioning. Because zStorage is not as widely adopted as the leading cloud storage platforms, certain integrations and tools may feel somewhat limited. Additionally, you might need to invest some time in learning about the various tiers and options to ensure you choose the best setup for your needs. Overall, these downsides are relatively minor, but they are still important to consider.
What problems is the product solving and how is that benefiting you?
zStorage helps solve the problem of managing complex, fragmented storage environments. Instead of juggling separate systems for block, file, and object storage, zStorage brings everything together in one platform, which makes it much easier to manage and scale. This benefits me by reducing the amount of time and effort spent maintaining different systems.
Another problem it solves is unpredictable storage growth and costs. With its pay-as-you-go model, I don’t have to overbuy hardware “just in case.” I can scale capacity up or down whenever I need to, and that flexibility keeps costs under control while still giving me enterprise-class performance.
It also removes a lot of the operational burden. Because it’s fully managed 24/7, I don’t have to worry about handling upgrades, monitoring, or troubleshooting storage infrastructure. That lets me focus on applications and business needs instead of backend maintenance.
Overall, zStorage benefits me by simplifying storage management, keeping costs more predictable, and giving me reliable performance without the complexity of traditional storage systems.

Outstanding Onboarding and Support with an Intuitive Interface
Reviewed on Nov 11, 2025
Review provided by G2
What do you like best about the product?
I was fairly new to storage when I fist started using Zadara. The onboarding was great. Went through all the areas that I would be using. The Zadara interface is easy to use. The customer support is some of the best I've worked with Easy to open a ticket and Zadara is quick to respond.
What do you dislike about the product?
The was an issue with one of our VPSA where were weren't alerted. The VPSA went down and we did not know for hours. After the issue was fixed we met with our Zadara reps and told that the issue and slow response would not happen again.
What problems is the product solving and how is that benefiting you?
I'm not if it is solving any problems but we needed a new storage platform during our data center move. Zadara has been a quality platform and performed well for what we need it for.

Object Storage with Effortless Scaling and Impressive Speeds at a Great Value
Reviewed on Oct 30, 2025
Review provided by G2
What do you like best about the product?
Zadara's zStorage platform makes it simple for us to scale our object storage target with minimal daily effort. The storage array is dedicated to our use, and the read and write speeds are outstanding considering the cost.
What do you dislike about the product?
Although the management GUI for the Object Storage (NGOS) platform has seen steady improvements, it remains quite limited. Performing tasks such as manual deletions or configuring advanced permissions (IAM) is still very restricted, and the majority of operations must be carried out through the command line.
What problems is the product solving and how is that benefiting you?
zStorage enables us to deliver a dedicated storage platform that can scale alongside our requirements, all while remaining on a dedicated array. Since our customers prefer not to have their data stored in a public cloud, zStorage gives us the ability to meet their preferences and offer a solution that is both flexible and cost-effective with its consumption-based pricing.

The cost is not favorable as Zadara does not provide competitive rates for regions like South Africa and Ethiopia. The pricing is considered expensive.
Which other solutions did I evaluate?
We are considering switching to AWS because of cheaper pricing.
What other advice do I have?
If companies have the budget, I recommend Zadara for small business classes due to its robust performance and user-friendliness.
I'd rate the solution eight out of ten.

Block storage and NAS capabilities but requires nondestructive firmware upgrades
Reviewed on Oct 14, 2024
Review provided by PeerSpot
What is our primary use case?
How has it helped my organization?
It provides very satisfactory storage performance, however, we don't use it for mission-critical applications.
What is most valuable?
We use both their block storage and also their NAS capabilities.
What needs improvement?
Every time they do a firmware upgrade, it should be nondestructive. Currently, when we do firmware upgrades, it sometimes causes issues and is not as nondisruptive as desired. It would be beneficial if they could support real-time synchronous replication.
For how long have I used the solution?
We have been using the solution since 2017.
What do I think about the stability of the solution?
We experienced some issues with stability. There were some downtime and glitches.
What do I think about the scalability of the solution?
From one to ten, I would rate scalability as eight. We have no issues with it.
How are customer service and support?
Technical support is fine. The response time and quality are pretty good, with no issues.
Which solution did I use previously and why did I switch?
We moved to other vendors.
How was the initial setup?
The initial setup is simple. We did not face any difficulties with it.
What about the implementation team?
We worked with a third-party provider in our geography with the reseller.
What's my experience with pricing, setup cost, and licensing?
It's a reasonable price, so I'd say it's around a seven on a scale of one to ten.
Which other solutions did I evaluate?
I would say Huawei, but I haven't used Huawei yet.
What other advice do I have?
Within certain constraints, users should use it only for their nonproduction workloads. Alternatively, for production, it should only be for noncritical workloads.
I'd rate the solution seven out of ten.

Cloud Outage - No Communication
Reviewed on Apr 18, 2024
Review provided by G2
What do you like best about the product?
Fast, mostly reliable block storage that allows me to connect the same disk to two different machines in two different AWS AZs
What do you dislike about the product?
On April 17, 2024 Zadara had a three hour outage. This was a significant disruption to our business. While we were happy they restored service in the timeframe they did, we haven't received any follow up communication on the root cause, so we don't know if we can trust them going forward.
All calls to their support line are auto-forwarding to a voicemail box, so it appears their support is woefully understaffed.

What problems is the product solving and how is that benefiting you?
Zadara allows us to connect the same volume to two different EC2 instances at the same time. You can't do this with AWS EC2 volumes. It allows fast failover between availability zones in AWS.
