What Buyers Say
The most surprising finding is the consistent and widespread reports of early drive failures, with some users experiencing data loss within weeks or months of purchase. Many buyers also discovered that the internal drives were refurbished, not new, which explains some of the reliability issues. Beyond hardware problems, customer support is frequently described as non-existent, leaving users without recourse when problems arise. While the 14TB capacity is appealing, these significant drawbacks make it a risky purchase for anything beyond non-critical data storage.
“Seriously, my 12TB unit died in 3 months, just clicking and gone. All my backups, gone. Don't buy this trash if you value your data, the 'warranty' is a joke.”
Common Praise
- Provides a massive 14TB of storage space.

Ownership Tips
- The drive might initially appear to work fine, but failures often occur within the first year.

- The actual usable capacity might be slightly less than 14TB due to formatting and system files.

Buying Guide
When you're looking at external hard drives, especially high-capacity ones like 14TB, you need to think about what you're storing. If it's important, you need reliability and good support, not just a low price. This drive uses a mechanical hard disk, which means it has spinning platters, making it slower and more fragile than an SSD. Also, 'desktop' means it needs its own power supply and isn't designed to be carried around.
Capacity (14TB)
This is how much data the drive can hold. 14 terabytes is huge, enough for thousands of hours of video or millions of photos. Think of it like a massive digital warehouse for your files.
Interface (USB 3.0)
This dictates how fast data moves between your computer and the drive. USB 3.0 is a common standard, offering decent speeds for large file transfers, but it's not the absolute fastest available today. It's like a multi-lane highway for your data.
Form Factor (3.5 Inches)
This refers to the physical size of the internal hard drive. 3.5-inch drives are larger and typically found in desktop external drives, requiring an external power source. They're built for stationary use, not for tossing in a bag.
Drive Type (Mechanical Hard Disk)
This means it uses spinning platters and read/write heads, making it more susceptible to damage from drops and generally slower than Solid State Drives (SSDs). It's like comparing an old record player to a digital music player – different tech, different performance.
Alternatives
If this drive doesn't fit, look for external drives with a solid-state drive (SSD) for speed and durability, or mechanical drives from reputable brands known for customer support and reliability if capacity is your main concern.
