Key Features
Consistent storage performance
SAT5221 is rated for steady-state performance in sustained workloads. Actual NAS performance depends on the host, RAID configuration and application.
Protection during power interruption
Integrated power loss protection helps preserve data in transit during a power interruption. Use appropriate backups and a UPS as part of the complete storage design.
Endurance suited to your workload
Endurance exceeds 900TBW for 480GB, 1,700TBW for 960GB, 3,500TBW for 1.92TB and 7,000TBW for 3.84TB. Choose capacity and endurance according to the expected write workload.
Compatible systems
All four SAT5221 capacities are supported in DS1825+, RS1226+ and RS1226RP+. Contact ACE to confirm other NAS or expansion configurations. The separately listed 7TB option is a different generation; confirm its exact model and specifications with ACE before ordering.
