Thermal Throttling Explanation
- Slight warming during continuous high‑speed reading/writing is normal for portable SSD products, not a hardware defect.
- Under long‑duration 4K 60FPS video recording or large‑file bulk copying, the drive will activate thermal‑protection throttling, which temporarily lowers write speed to protect flash memory chips.
- For best heat dissipation, place the drive in open‑air space. Avoid covering it inside bags, cushions or enclosed narrow spaces.
- High ambient summer temperature will increase the probability of speed throttling.
- After long‑time heavy‑duty writing, allow the drive to cool down for a short while before continuing intensive
Rated Speed vs Real‑World PerformanceOur peak read/write figures are measured under ideal lab conditions: nearly empty drive, direct Gen2 USB port, UASP enabled, copying large continuous files with no background system tasks
Real‑world performance will drop under these scenarios:
- Drive storage is more than 50% occupied
- Transfer massive amounts of small fragmented files
- Connected via USB hub, docking station or front‑panel motherboard ports
- Mobile phone direct video recording, limited by phone power‑supply and system constraints
File‑System Recommendations
- Factory default format: exFAT, cross‑compatible for Windows, macOS, Android and iPhone 15 series.
- Avoid NTFS format: macOS can only read NTFS without third‑party software, cannot write data.
- Avoid APFS format: Windows cannot recognize APFS drives.
- WARNING: Format operation erases all stored data. Always back up files in advance.
- Always safely eject / unmount the drive before physical unplugging to prevent file corruption.
Important Data‑Safety Reminder
This portable SSD works as expanded mobile storage. DO NOT rely on it as your sole backup for irreplaceable photos, footage or critical documents. Always maintain multiple copies of your important files.
Unexpected power cut, hot‑unplug without safe eject, static electricity or extreme high‑temperature environment may lead to file corruption or data loss. Please back up your key data regularly.
Notes for iPhone 15 Direct 4K Video Recording
- Direct‑camera recording works for iPhone15 /15 Pro / Pro Max series.
- Low‑power mode on iPhone will limit external storage write performance, which may cause recording stalling. Please turn off low‑power mode before shooting.
- Phone case and magnetic accessories may affect overall heat dissipation of the whole setup.
- If recording fails: try swapping cables, re‑plugging the USB‑C port and disable low‑power mode.
