Yes, the Toshiba MG10 20TB SATA uses a standard SATA 6Gb/s interface and 3.5" form factor, compatible with any NAS that accepts 3.5" SATA drives. It is widely supported by Synology, QNAP, TrueNAS, and Unraid systems. The 550 TB/year workload rating makes it suitable for always-on NAS environments.

Can I use the MG10 20TB SATA in a RAID array?

Yes. The Toshiba MG10 20TB SATA is designed for RAID deployments. Its 550 TB/year workload rating and 2,500,000 hours MTBF ensure reliability in RAID 5, RAID 6, RAID 10, and ZFS configurations. Enterprise and NAS drives include error recovery features (TLER/ERC) for RAID controller compatibility.

What does the 550 TB/year workload rating mean?

The workload rating indicates the maximum annual data transfer the drive supports while maintaining stated reliability. 550 TB/year means the drive supports approximately 1.5 TB of data transfer per day, suitable for busy file servers and multi-user environments.

How fast is the MG10 20TB SATA?

The Toshiba MG10 20TB SATA spins at 7,200 RPM with a 512 MB cache buffer, delivering sustained transfer rates up to 268 MB/s. This is optimal for sequential workloads like large file transfers and backup operations.

How much power does the MG10 20TB SATA consume?

The Toshiba MG10 20TB SATA draws 8.11W under operating load and 4.38W at idle. For multi-drive configurations, factor these values into your power budget — a 12-drive array would consume approximately 97W under load.
