Designed-for use-case for an SD card is a buffer where a photo/video camera will save footage sequentially, then you copy everything to your PC/laptop and reformat the card.
When used as a generic storage with a complex write/delete/overwrite pattern, most card would start corrupting data fairly quickly.
- overcast 10y agoI understand its use case. Now imagine you're on location shooting, and you're fumbling around with tiny SD cards. It wouldn't be the first time I've dropped one. Even compact flash I try not to put TOO much work on one before I switch them over. To say that every consumer is going to use it only as a temporary medium, I think is overly optimistic.
- cptskippy 10y agoI think part of the appeal of high capacity cards is that you spend less time fumbling with cards. A 1TB card would probably last an entire day of shooting HD video. As an amateur photographer, I generally keep 2 extra SD cards on hand but they're backups and not used. I don't think I've ever filled up the 64GB card that I shoot with and at the end of the day I move off what was shot. If I'm shooting on vacation I'll generally leave a copy of the images on the card so that I have 2 copies floating around but I've yet to fill up the card. This card probably isn't targeting the consumer market. I think smartphone cameras have cannibalized much of the Point-and-Shoot camera and PVR market. That being said, I think most consumers purchase one SD card when they buy their camera and it's the only card that camera ever sees.
- eropple 10y agoI get what you're saying, and it is a concern, but there is a decent argument (to me, anyway) that with 1TB you probably won't be taking the card out to be fumbling with it in the first place. Even with on-location shooting, "I filled up a 1TB card, I need to archive it" is probably a good reason for a lunch break.
- overcast 10y agoNo one in their right mind would fill a 1TB card before swapping. That's an insane amount of potential lost. I could see it as a secondary backup disk in DSLR about it.
- colejohnson66 10y agoNot that you're wrong, but [citation needed]. Mainly because you use a microSD card to boot the Raspberry Pi. Also, in my Yearbook class in high school, we almost never formatted(?) our cards. Granted, they were only 32 GB or less to avoid SDXC, but still.
- cptskippy 10y agoWhy were you avoiding SDXC? Was it a technical deficiency in SDXC or limitation in your hhardware?
- rocky1138 10y agoI'm not the parent, but SDXC on my Raspberry Pi causes kernel panics after ~6 hours of operation. It's entirely annoying.
- colejohnson66 10y agoAre you formatted as exFAT? Because it's my understanding that Windows will refuse to format an SDXC as anything but.
- rocky1138 10y agoI believe it was ext3 or ext4, but I'd have to look.
- colejohnson66 10y agoWe did have a few cameras that supported SDXC, but the majority didnt. It was easier to just use SDHC and not have to worry about what card works in what camera. Besides, 32 GB was plenty because we almost never shot in RAW (high schoolers aren't professionals); I think only me and 3 others knew about working with RAW. So to answer your question, space wasn't a premium, and because of the technical and human limitations of SDHC vs SDXC. I'm sure some of those cameras had firmware updates that would add SDXC support, but we didn't need it.
