Synology SAT5221-1920G 1.92TB 2.5" SATA/600 Internal Solid State Drive

The Synology SAT5221-1920G is a 1.92TB internal SSD with a 2.5-inch SATA interface and DRAM cache, suited to users who need solid-state storage for a system compatible with those specifications.

Recommended For

• Synology NAS administrators building an all-flash storage pool who want a 1.92TB enterprise SATA SSD and have confirmed this exact model is compatible with their NAS.
• Small-business or IT teams running compatible Synology systems for shared file, block, or iSCSI storage, where sustained enterprise workloads matter more than maximizing capacity per dollar.
• Operators with write-heavy NAS workloads who want a drive rated for enterprise endurance; Synology lists more than 3,500 TBW for the 1.92TB SAT5221 and a five-year limited warranty, subject to the endurance limit.
• Organizations standardizing on Synology-validated drives for supported NAS deployments, especially when they prefer to check the manufacturer's compatibility list before buying.

Real-World Use Scenarios

• For a Synology NAS running virtual machines or serving iSCSI storage, use the SAT5221-1920G as an SSD volume to handle frequent, latency-sensitive reads and writes; the SSD-based storage can make VM and application access more responsive than relying on hard drives alone.
• For an OLTP database or other frequently accessed business application on a compatible Synology system, use it as primary SSD storage to support recurring, I/O-intensive activity with more consistent responsiveness than a hard-drive volume.
• For multimedia post-production on a compatible Synology NAS, use it for active project files and frequently accessed media; the SSD can improve access to working data, while the SATA interface and NAS setup still shape transfer speeds.
• For an HDD-based Synology NAS where several users repeatedly access the same files or application data, configure compatible SSD cache to keep frequently requested data on SSD; repeated reads may become more responsive, but one-off or large sequential transfers are less likely to benefit.
• For a NAS hosting several frequently used services with mixed read-and-write activity, use the drive as part of an all-flash volume or a supported cache configuration; it is designed for intensive workloads, but the improvement depends on NAS compatibility, workload, and system or network bottlenecks.
