    Frequently Asked Questions

    None right now: all 2 tracked MDD 22TB SAS listings are out of stock. The table fills back in when an offer returns; nearby capacities are linked on this page.

    None of the 2 tracked listings (including the MDD 22TB SAS 12G 7200RPM Enterprise) has a manufacturer-sourced recording value yet, so this page states none - an unsourced drive is never assumed CMR.

    Use Case Scenarios

    🏠
    Home & SMB NAS
    Building a high-capacity NAS for media, backups and file sharing.
    ~ Good fit
    Verify CMR recording before using in RAID. New drives come with full warranty.
    💾
    Backup Server / Veeam Target
    Dedicated backup storage for Veeam, Commvault, or NetBackup.
    ✓ Excellent fit
    22TB 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 22TB per drive, a 60-bay JBOD delivers 1320TB 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 11 hours for 22TB. 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 MDD 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 22TB 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.
