High-capacity and high-speed SD and microSD cards will receive improved Linux support on the latest 6.11 kernel update.
Does any device support UHS-II except cameras or cardreaders?
What kind of devices do you have in mind that use cards but are neither of those?
ROG Ally X. I don’t know about other handhelds.
128 terabytes?? Wtf
It’s crazy, in 2035 that should fit at least 6 games
I’m still getting over disks above 250GB being common.
Those have been around for close to 20 years at this point.
I think I paid $100 or so for a 180GB? Drive around 20 years ago. About 14ish years ago I paid a decent amount for a 120gb ssd.
128TB SD cards sounds awesome if they perform well. Now if we could just get a 128TB microSD that performs close to a PCIe I’ll be swallowing my OS in a digestion proof container if necessary.
SD Express is advertised as PCIe gen 3 speeds (~1GBps) but will be a while before we see a microsd like that lol
I guess I could swallow an SD card if I had to. 😮
Not quite the same thing but modern high end cameras use CF-Express (as in compact flash). They communicate over PCIe using the same protocol as NVMe drives but have fewer lanes and usually are smaller. The tricky part is with their small size you don’t have as much room to cram as many flash chips onto a card compared to a 2280 NVMe.
Looking at the actual commit notes, it is SDUC support, which starts at 2TB and goes up to 128TB
I find it hard to believe they only recently added GPT partitioning support , or was there some other issue happening with the removable storage mediums above a certain amount?
Nah, it’s just SDUC cards are a different hardware design.
I’m not sure I’m following, what was the technological leap here? I know that the SD, SDHC, SDXC, etc. are marketing terms and their limitations are based on other factors, much of the previous ones are file system related.
- SD - FAT16 Volume size limit, Practical limit 2GB, Max limit 4GB
- SDHC - FAT32 limit Set at 32GB by Microsoft (fake limit)
- SDXC - 2TB limit, Maximum partition size for MBR partition Scheme.
I assume that it’s a similar story here but it might not be, if so I’m curious as to what changed.
The I/O commands are different as well, the hardware has to support SDUC.
