Version 7.0 of the SD standard finally raises the storage limit to above 2 TB, which was being rapidly approached by both full size SD cards (1 TB) and microSD cards (512 GB). It also adds an SD Express mode, which can raise speeds up to 985 MB/s, from a previous limit of 624 MB/s:
Soon you will be able to purchase new SD cards with the SD Version 7.0 specification. The new specification supports up to 985MB/s of throughput, which comes courtesy of PCIe and NVMe interfaces, and up to 128TB of capacity. That's quite the jump over the current 2TB limit.
985MB/s of throughput for a simple SD card may seem ludicrous, but higher-resolution video, VR, automotive use-cases, and IoT applications are steadily encroaching upon the performance limits of today's products.
[...] The specification has reserved space for new pins for future use, so it also provides room for forward progress (PDF). The specification also accommodates up to 1.8W of power consumption, which will help boost performance. The NVMe 1.3 protocol also brings several new features to SD cards, like Host Memory Buffer (HMB), which sets aside a small portion of system memory to boost performance, and Multi-Queue support, which improves performance during simultaneous file transfers.
Press release. Also at PetaPixel.

I never thought I'd be doing this, but these TF cards store so much data that I am using my phone to backup the critical data files on my workstation.
The Android has an FTP server app you can download. Once I have the phone FTP server running, I then start the WS-FTPLE ( that old FTP client IPSWITCH had out there for years ) and transfer the filesets to or from my phone.
Almost as easy and not as fast as just plugging in a local USB stick, but it does give me knowledge that should I botch a fileset or worse, lose my system, at least I have the incremental backup since the the last disk image right on my phone. I never know when I may do something stupid, like visit the wrong website and get a piece of malware injected into my machine.
I still use something like the Western Digital Passports for keeping disk images on, but I only back up to those maybe once a month or so. And before and after any major system change.

on the other hand, if you drop your phone on the bus or something, suddenly all your data are belonging to someone else.
don't get me wrong, redundancy is a good thing, but usually your computer should be safer than your phone...

Whoever picks up your phone will probably just wipe it and sell it on. But if you are concerned about data security, you can encrypt the files before sending them to your phone.
