Author infoRatingReview Summary
Enterprise Storage Administrator at a healthcare company with 1,001-5,000 employees4.0I find FDS to be a flexible, easily deployed, and stable solution with excellent support. Its high deduplication ratios significantly save storage, though it currently lacks snapshot capabilities.
Senior System Engineer at a tech services company with 51-200 employees4.0I find Falconstor offers great scalability and performance, with high availability being a killer feature. Despite complex initial setup for HA, I've experienced no issues in 7 years, though reporting could improve.
