MDD is an Amazon seller specializing in refurbished enterprise hard drives, datacenter pulls from Seagate Exos, WD Ultrastar, and other enterprise lines. They often offer the lowest cost per TB on Amazon, but with trade-offs in warranty length and unknown drive history.
MDD drives are often 40-60% cheaper than new enterprise drives. If you need bulk storage on a budget, they're hard to beat.
These are real Seagate Exos and WD Ultrastar drives, the same models datacenters use. CMR, high MTBF, RAID-optimized.
Unknown usage history, shorter warranties (typically 2 years), and inconsistent QC. Always check SMART data immediately.
MDD is not a hard drive manufacturer. They're a reseller that sources "datacenter pull" drives, enterprise HDDs removed from decommissioned servers, cloud infrastructure, or storage arrays. These drives are tested, relabeled, and sold as "renewed" or "refurbished" on Amazon.
Here's how MDD refurbished drives compare to buying new enterprise drives from authorized retailers.
| Factor | MDD Refurbished | New Enterprise |
|---|---|---|
| Price (16TB) | ~$120-150 | ~$280-350 |
| Cost per TB | $7-10/TB | $17-22/TB |
| Warranty | 2 years (seller) | 5 years (manufacturer) |
| Usage History | Unknown (check SMART) | Zero hours |
| Quality Control | Inconsistent | Factory QC |
| Drive Quality | Enterprise-grade (Exos, Ultrastar) | Enterprise-grade |
| Best For | Budget builds, redundant storage, media servers | Production, mission-critical, business use |
Amazon's A-to-Z guarantee protects you. If a drive arrives DOA or fails within 30 days, returns are painless. Buying directly from third-party sites is riskier.
Run SMART diagnostics the day you receive the drive. Check Power-On Hours and Reallocated Sectors. Return within Amazon's window if anything looks wrong.
If you're building a 4-drive array, buy 5 drives. Use the healthiest 4 and keep one as a hot spare. The savings over new drives more than cover the extra unit.
Drives from the same batch may fail around the same time. Buy from different listings or at different times to reduce the chance of simultaneous failures.
