Since I'm not a photographer or video editor I feel like my SDXC slot is just going to waste lol. Looking for some ideas on what people use it for outside of the obvious 2 uses. I think I read someone on reddit using it for his time machine backups, is that possible or reliable?

I am a photographer/videographer, but I usually have a Micro SD card inserted (with a slim adapter). This gives me more space to offload video files for reference on projects. I find it convenient and don't have to carry around an external SSD for those files.

do you mind sharing which one you got? I am intrigued now with using it for time machine.
I got the 1TB card.

SanDisk 1TB Extreme PRO SDXC UHS-I Memory Card - C10, U3, V30, 4K UHD, SD Card - SDSDXXD-1T00-GN4IN​

I was thinking about that as well but since the SD card you can’t leave in the port anyway i guess a SSD is more practical cos its more durable and not lost that easily.

for $30 less you get a Samsung T7 with double the storage and min. 5x faster.

I have 2 of the T7 drives I use for TM. They work great. I thought I would see what the micro card was like and it works but, very slow. lol

I use it to transfer videos off my dash cam. I don’t edit them except to trim some parts with VLC.
Kind of off topic but I also transfer my crazy dash cam vids to my Mac and when my daughter is old enough to drive someday I'm going to edit them together into a big montage, post it on YouTube, and make her watch it before I teach her to drive. Then when she says "Yeah dad, I get it, there are some crazy drivers on the road, I've seen these compilations before." I'm going to drop the bomb that all of these crazy videos are things that only I recorded and that's why you need to be a really careful and a defensive driver on the road. I've avoided a lot of crazy drivers and accidents! Although my numbers have dwindled since I started working from home a few years ago.

Other devices that use SD cards:
  • Audio recorders
  • Drones - although could be considered to be a photo/video use, not sure if they store config data too?
  • Raspberry Pi or other embedded computers
  • Photo frames that play a selection from the card
  • Mobile phones with slot for extra storage
  • Some consumer or specialist electronics where removable data storage is needed - I have some astronomy gear that stores star catalogs on SD

Ever since Nikon D4, my main card has already been XQD, then moved on to modern (flagship) cameras where CFExpress is the norm. SD is still quite popular in smaller devices due to its small footprint though, especially with microSD.

Hi,

I use 1TB micro-SDXC cards for offsite backups. In particular, I use a script that gtar-s (Apple's tar does not archive all files, but gtar does), bzip2-s the tarfile, encrypts with RSA, then splits the encrypted archive into 1GB subfiles, shasum-s all of the split files, and copies all of the split files and necessary scripts to the micro-SDXC card. I then send a micro-SDXC to the East Coast, one to the Gulf Coast, and one to the West Coast. There is a script that copies the split encrypted and compressed archive onto large HDDs at each site and checks the checksums to make certain that there were no transmission errors; and another script that will merge, decrypt, uncompress, and extract the tarfile, if needed.

The micro-SDXC-s are easy to tape to the inside of a Hallmark card and USPS mail to the three offsite locations.

I know that this is "ridiculous" ... but it works. And can be used to transfer other things, such as family photos that you don't want to loose or be stolen during transfer -- the encryption makes sure that even if the micro-SDXC card doesn't make it to the proper destination, you don't have to worry about anyone else having access to the archive on the card.

Just curious, who receives and checks and archives your offsite backups? Colleagues or just really good friends 😆? I’d guess these are work backups?

Previos colleague, student, and a current colaborator on a small project included in archive.
