NetApp's hot and cold storage are its most valuable features. We currently use the A series. Immutable snapshots are another advanced security feature that is positive.
NetApp AFF A-Series offers high performance and low latency, efficient data reduction, robust data protection, and scalable storage with excellent customer support. However, some users have noted higher costs, limited compatibility with legacy systems, challenging firmware upgrades, occasional performance issues under heavy workloads, and slower-than-expected customer support response times.
