How to Move 4K Video from Your Phone to an External SSD Without a Laptop
Your phone is full of 4K video and there is no laptop in sight. Good news: you can move those clips straight to a portable SSD with a single USB-C cable. No laptop, no paid app — just the phone, the drive, and a file manager. Why an SSD, not a flash drive? 4K video is big and needs sustained write speed. A 10-minute 4K30 HEVC clip is about 1.7 GB, 10 minutes of 4K60 is about 3.9 GB, and 10…
Want to transfer 4K video from your phone to an external SSD without using a laptop? You can accomplish this with just a single USB-C cable. You won't need any paid software, only your phone, the external SSD, and a file manager app. The reason to opt for a solid-state drive (SSD) over a flash drive is the need for sustained write speed.
A 10-minute 4K30 HEVC clip is roughly 1.7 GB, while 10 minutes of 4K60 video is about 3.9 GB, and ProRes 4K video on an iPhone can be as large as 11.7 GB. Alternative to a flash drive, SSDs can handle multi-gigabyte files at rates of hundreds of MB/s. To test, I used published bitrates from various sources and formatted the SSD as exFAT, since FAT32 rejects files larger than 4 GB and one 4K60 clip over 11 minutes would exceed that limit.
I created an 8 GB disk image in FAT32 and tried copying a 4.5 GB video file; it was rejected instantly and the directory remained empty. The 4 GB limit is not a spec footnote. There is one caveat: I couldn't test large-file writes on an exFAT-formatted drive on the test machine, so the claim rests on official guidance from Apple and Samsung.
