What customers say
Power users highly value the Seagate Exos X20 20TB drive for its massive capacity and robust 7200 RPM performance, which ensures excellent sustained transfer rates for continuous, heavy-duty workloads. Its enterprise grade reliability offers significant peace of mind for critical server and NAS environments. Many consider the value proposition strong given the high density offered at a competitive price. The main drawback noted by users is acoustic performance; this high capacity drive is notably loud during seek operations, making it less suitable for quiet desktop setups. Despite this, the consensus remains that for high volume, continuous operation where noise is managed, this drive is a top tier choice.
