Frequently Asked Questions

Is the MG09 18TB SAS compatible with my server?

The Toshiba MG09 18TB SAS uses a SAS 12Gb/s interface and requires a SAS-capable HBA or RAID controller. It is NOT compatible with standard SATA ports. SAS drives are designed for enterprise servers, SAN arrays, and high-performance storage subsystems.

Can I use the MG09 18TB SAS in a RAID array?

Yes. The Toshiba MG09 18TB SAS 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 MG09 18TB SAS?

The Toshiba MG09 18TB SAS spins at 7,200 RPM with a 512 MB cache buffer, delivering sustained transfer rates up to 281 MB/s. This is optimal for sequential workloads like large file transfers and backup operations.

How much power does the MG09 18TB SAS consume?

The Toshiba MG09 18TB SAS draws 8.35W under operating load and 4.16W at idle. For multi-drive configurations, factor these values into your power budget — a 12-drive array would consume approximately 100W under load.
