Questions about this item

How does the 7200 RPM speed translate to everyday performance inside a Synology NAS?

The 7200 RPM spindle delivers sustained throughput for multi-client workloads, and DSM firmware tuning improves sequential read performance by up to 35% in compatible systems.

What does the SATA interface limit on this 16TB drive?

The SATA connection caps the maximum transfer rate at the SATA III 6 Gb/s ceiling, so the drive cannot exceed that bandwidth regardless of its internal speed.

Will the 26.1mm height fit my standard 3.5-inch drive bay?

Yes, the 26.1mm height, 101.85mm width and 147mm length match the standard 3.5-inch form factor used in most desktop chassis and NAS enclosures.
