Backup/Hard Drive Questions

It's on sale in B&H now.

If you saw my original post, I tried copying and pasting the 26.2G worth of files to a USB flash drive (Onn, USB-A) and it was quoting me a time of TWO HOURS. Are you saying these are much faster? I will also say I popped in a spare 64G SD card (Class 10 I believe) into this very same PC to test its speed (using its built in card reader), it took around 6 minutes.

It will depend on the specific Flash drive/SD card and the usb port you use for the flash drive vs SD card.

If your Onn is USB 2, the transfer rate is ~33MB/s (hence 2 hrs). The USB 3.0 (above) max out 625MB/s, but you will not get that kind of speed, in practice, probably ~100-200MB/s. USB-C can range from ~33MB/s to 625MB/s (3.2 gen 2 doubles that).

Cables matter too. Wrong cable, it was ~33MB/s for an external SSD, and proper ones, over 300MB/s.

USB is a mess - transfer rates depend on ports, cable, and media (+ports).

Where appropriate, I have copied the files from SD cards to computer/backup, but I’ve never had a failure of an SD card. It’s only recently that I’ve formatted the half dozen cards that I brought home from my trip to Italy in 2015. (Been using larger cards since then).

when I got the R5 in 2020, I also got a 2TB CFE card (was only slightly more than the 1TB variant). But since I don't shoot 8k/4k video much, not remotely close to filling it. And yet, the card became slow to write it and even hard to pull from last year, to the point where I feared some sort of firmware/hardware failure. But as soon as I got the content off (OSX did better here than Windows), and reformatted, all was good again.

I don't want to touch the flash until I've complete the copy over to the NAS and it's secondary backup. But now I'm somewhat inclined to clear cards before a trip, as I'm often wondering if I actually copied the contents to the NAS or not. Worst is with gopro cards as if you don't recheck the date, you may find its reverted to 2016 and all your videos look ancient as a result.

CFE cards are much cheaper now - I have a 2nd one (500gb) so that I can always swap during a trip. Broader lesson here - 2 is the minimum number of flash cards you should carry.
