Frequently Asked Questions

Toshiba 18TB SAS drives are enterprise-grade and designed for 24/7 datacenter operation. Check individual model specs for MTBF and workload ratings.

New Toshiba 18TB SAS drives are available with manufacturer warranty. Worth the premium for mission-critical deployments.

RAID 6 is strongly recommended for 18TB SAS drives. At this capacity, RAID 5 rebuild times exceed 24 hours - too risky for a single parity stripe. Use RAID 6 or RAID 60 for arrays of 12+ drives.

Use Case Scenarios

🏠

Home & SMB NAS

Building a high-capacity NAS for media, backups and file sharing.

18TB SAS drives are ideal for backup targets. Dual-port SAS suits dual-path backup infrastructure.

☁️

Object Storage / Cold Data Tier

High-density storage for MinIO, Ceph or Hadoop at scale.

✓ Excellent fit

At 18TB per drive, a 60-bay JBOD delivers 1080TB raw — enough for petabyte-scale object storage.

Maintenance & Troubleshooting

Maintenance Checklist

On installCheck SMART baseline on arrival

Run smartctl -a /dev/sdX and record: Reallocated_Sector_Ct, Power_On_Hours, Spin_Retry_Count. Establishes baseline for future comparison.

MonthlyRun SMART short self-test

smartctl -t short /dev/sdX — takes 1-2 minutes, catches most developing issues. Schedule during off-peak.

QuarterlyRun SMART long self-test

smartctl -t long /dev/sdX — full surface scan, takes 9 hours for 18TB. Any test failure is grounds for immediate replacement.

QuarterlyCheck RAID array health

Verify no degraded drives. A degraded array with no hot spare is one failure from data loss. Check mdstat or controller UI.

AnnuallyVerify drive firmware version

Check Toshiba support site for firmware updates. Some versions have known bugs affecting integrity.

Every 3-5 yearsPlan proactive replacement

Enterprise HDDs have higher failure rates after year 4-5. At 18TB per drive, budget for replacements before failures occur.

Troubleshooting Guide

Cause: HBA not initialized, SAS expander issue, cable fault, or incompatible controller.

Fix: Verify HBA firmware. Check SAS topology with sas2ircu or StorCLI. Test with known-good cable. Confirm drive is SAS not SATA.
