Synology SAT5221 Enterprise SATA SSD

The Synology SAT5221 is a 3.84 TB internal solid-state drive built for enterprise workloads. It uses a 2.5 inch form factor and connects via a SATA 6Gb/s interface. The drive targets businesses and IT professionals who need consistent read and write performance for always-on storage arrays.

Thermals noise and power draw in normal use

The SATA interface and 2.5 inch design fit standard drive bays and hot-swap trays without extra adapters. Solid-state construction eliminates mechanical noise and reduces vibration compared with spinning disks. Typical power consumption stays low during sustained read and write operations, helping to keep chassis temperatures manageable in dense rack deployments.

Questions about this item

Will this 2.5-inch SATA drive fit my Synology NAS drive bay?

The SAT5221 uses a standard 2.5-inch form factor and SATA 600 interface, matching the drive trays in most Synology NAS models that accept 2.5-inch SATA SSDs.

Is any extra hardware needed to install this SSD in a 3.5-inch bay?

A 2.5-to-3.5-inch drive bracket or adapter is required when the chassis only provides 3.5-inch drive bays.
