Synology HAT5310-20T 20 TB 3.5 in SATA Enterprise HDD

Store more data per bay and keep your storage architecture simple with Synology’s 20 TB 3.5-inch SATA enterprise hard drive. This model is designed for capacity-heavy deployments where large sequential workloads, centralized file storage, and long retention windows matter more than flash-level latency. The SATA interface keeps integration straightforward across compatible NAS and server platforms. At 20 TB per drive, it helps reduce the number of bays required to reach usable capacity, which can lower enclosure count, simplify expansion planning, and improve storage density. That matters in environments where rack space, power, and maintenance overhead all carry real cost. The enterprise positioning also makes it a better fit for always-on systems than consumer desktop drives. Choose this drive when you need dependable bulk storage for backup repositories, media libraries, surveillance archives, or shared business data. It is a practical option for organizations that want to scale capacity without changing the storage model every time the dataset grows.
