I can't fathom a good reason for 4TB SD cards.
Most cameras have CF Express which is probably 5-8 times faster.
Even UHS-III is 600MB/s while CF Express Type B is hitting 4GB/s.
Even so, why would you risk 4TB of data on removable storage.
CF Express is also running PCI-E. This article isn't talking about SD Express.
I think it's primarily targeting the handheld gaming market
Steam games. I want to have all my 50-100 GB games available without having to decide what to uninstall.
Currently I have two 512gb SD cards for my Steam Deck.
If it craps out, it's okay.
We need a better storage solution than SD cards…
Doesn’t the steam deck have an upgradeable nvme drive? That would be a much better solution.
~~80mm~~ 30mm m.2 drives are to much of a niche
I think you mean 30mm (that’s what the steam deck uses, 80mm is the standard).
At about $80 per TB, it is more expensive than the 80mm ones, yes. But still comparable to SD cards an much faster and more reliable.
Yeah I meant the stubby smaller size.
I always forget the sizes of the M.2 :D
My laptop has an SD card slot. So if this were reliable I could add a significant permanent storage capacity to my laptop.
Valid point, but I think most built in SD card slots are on a laptop can read 100MB/s. Hopefully yours is perhaps USB 3.0 speeds.
It's good for offloading things that otherwise eat useful fast storage.
For example, OneNote uses a cache and a backup folder. So whatever size your notebook is, it will consume 3x that storage space.
I use the SD slot for the cache and backup folders (my backup folder is synced to a file server, so I don't need it locally, and in 15 years of using OneNote, I've needed that backup one time).
It's also useful for temporary stuff that you don't care about/is available elsewhere. I'll pull large installers from my file server and put them on the SD, until l I get around to using them (laptop drive is 250, which is tight for me, and the SD was a quick, dirty solution since I have a bunch of micro SD's from phones over the years).
I would happily use one for my music and movies to access them on the go. I already have copies elsewhere, so it would be no big loss if the card died.
If you set it up properly (like using apps to sync folders) a big enough sd is like local "cloud" service.
I was thinking about it recently, after my phone data were very close to being deleted (I managed to prevent it eventually), I was angry at how not having an sd slot caused me so many issues. If I had a 1tb sd I would just autosync app backups and files to my card and not worry ~at all about losing data from bootloops etc.
