Pros & Cons
Pros:
-
Very large storage (18 TB) good for storing lots of data: backups, video/photo libraries, etc.
-
Built-in hub ports at front — useful to plug in / charge phones or USB devices easily.
-
Security options (password, encryption) as standard.
-
Includes backup software and data recovery service, which adds value.
Cons:
-
Being a desktop drive, it takes more space and needs external power and proper ventilation; more fragile than portable drives.
-
Speeds will be limited by USB 3.0 (micro USB to host), not as fast as e.g. USB-C 3.2 Gen2 or Thunderbolt / SSD drives.
-
If used heavily (lots of writing), power use and heat should be managed well.
Use Cases & Tips
-
Great for archiving large media (videos, raw photos), backups, or as a centralized storage hub for multiple devices.
-
If you have a Mac and want to use Time Machine, you may need to reformat to HFS+ or APFS; for Windows NTFS or exFAT depending on cross-platform usage.
-
Keep the drive in a cool, ventilated spot to avoid overheating.
-
Regular backups / checks: even though it is large and reliable, mechanical HDDs can fail. Having redundant backup (or periodically copying critical files elsewhere) is smart.
