Frequently Questions
Answer:
This is completely normal and happens with every SSD, USB drive, and hard drive (not just addlink).
Different ways of calculating capacity. The capacity printed on the box uses 1TB = 1,000,000,000,000 bytes (decimal / 1000-based).
Your computer calculates using 1TB = 1,099,511,627,776 bytes (binary / 1024-based). Because of this, a “1TB” SSD usually shows around 930–950 GB in Windows. This is universal across all brands.
Answer:
99% chance you’re not using a 20Gbps port.
Old black USB → max 40 MB/s
Blue USB or normal USB-C → max 400 ~ 1000 MB/s
Only USB-C ports marked “SS 20” → full 2000+ MB/s Switch to a port that says 20Gbps and watch the speed double instantly!
Answer:
Yes! Just use the USB-C end plug and play. You can back up photos, watch 4K movies, or even record video straight to the P21 to save phone space. No adapter needed.
Answer:
It gets warm (like your phone when it’s working hard), but it’s totally safe. The metal body cools it down fast. If it ever gets really hot, it will slow down a tiny bit by itself to protect the drive that’s a feature so it lasts for years.
