Excellent performance, scalable, easy to install, and outstanding support
Both the pricing and the performance are excellent. I don't have any issues with this solution at all. In my use case, there is nothing I would change about it. They continue to do more with regards to usability, and then security around ransomware. That is what their recent improvements have been.

Quotes from Members

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

Pros

"Both the pricing and the performance are excellent."
"The most valuable features of ExaGrid EX are the Veeam features and Landing Zone."
"This is a user-friendly solution."
"The most valuable features for us are the ease of use, the reliability, and the exceptional deduplication that we get across that data that we store on those devices."
"I like the tool’s deduplication feature. We get a ratio of 9:1 for deduplication. The product is also Linux based. Last year, our organization faced some virus attacks. However, the backup was safe because of the product being a Linux version. HPE StoreOnce is a secure product."
"The implementation is not that complex for someone who has experience."
"Quick recovery."
"HPE StoreOnce works well, it is stable."
"The product's most valuable feature is stability."
"It is a very scalable solution."
 

Cons

"I would like to see free disk space."
"The solution’s web access should be improved."
"HPE StoreOnce could improve the capacity support."
"The solution's technical support should be faster."
"HPE StoreOnce should come with a detailed installation guide."
"The web interface, ease of use, and GUI all need to be improved."
"Its customer service could be faster."
"The setup phase is not so simple that an end user can plug and play to make it operational."
"Some high-level cybersecurity features could be achieved with some entities, and their integration could be built into the store."
"We archive our backups on tape, so I feel like if we could somehow plug our tape drive directly into the StoreOnce device and set it up to where it would archive based on, if some kind of rules based engine or what have you, that would really be an improvement for us."
 

Pricing and Cost Advice

"I rate ExaGrid EX ten out of ten for pricing."
"The renewal fee is approximately $3,500 to $3.750 for a 60 terabyte device."
"The solution is pretty expensive."
"The cost of HPE StoreOnce is very expensive."
"To be honest, we were quite happy with the price, but we always want things cheaper than they are. I think for what we got, we felt that the price was quite reasonable comparing it to other products that provide that same level of functionality."
"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."
"The price puts me off. It's definitely on the high side."
"The product's pricing is medium."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"The solution's cost is above average."
