Lexar's 1TB SD card is the first you can actually buy
SanDisk showed off a 1TB SD prototype a couple of years ago, but the final product never made it to market. Lexar's Professional 633x line of SDHC and SDXC UHS-I cards, however, is now listed for sale in capacities from 16GB all the way up to the flagship 1TB. That card claims read speeds of up to 95MB/s and write speeds of 70MB/s, though it's only rated as V30/U3, which guarantees sustained write performance of 30MB/s.

Here's a challenge: do you reckon you can fill half-a-terabyte of memory using only a smartphone?
For some people, we're sure, the answer will be along the lines of “hold my beer while I set my camera to HDR mode and snap some selfies”. So the good news is that from February, you'll be able to lay out the readies on a 512 GB microSDXC card from Integral Memory.
At a transfer rate of 80 megabytes per second, you'd need more than an hour and a half to transfer a full card's worth of data; last year's 400 GB monster from SanDisk (no longer the world's biggest little memory card) still has the edge there, claiming a 100 MB/second transfer rate.
Integral's 512GB microSDXC V10, UHS-I U1 card is fast enough to meet V10 (Video speed class 10) for capturing full HD video.
Integral has put up a web page and a Spec sheet (pdf) for it.
Now we can set them up as media hubs for all.
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.

Previously: Western Digital Demos SD Card Using PCIe Gen 3 x1 Interface for 880 MB/s Read Speed
SD Express will allow SD cards to reach read/write speeds of up to 985 MB/s. Now controllers for the standard are starting to appear:
Last year the SD Association published its Secure Digital 7.0 standard that defines SD Express cards. At this year's Computex, Realtek demonstrated one of the industry's first SD Express controllers for appropriate card readers. The RTS5261 chip already exists in silicon, so it is a matter of time before it is used for actual products.
[...] Realtek's RTS5261 supports everything mandated by the SD 7.0 specification and connects to hosts using a PCIe 3.0 interface. The controller can work with SDUC cards featuring capacities of up to 128 TB at sequential read/write speeds of up to 985 MB/s. Actual prototypes of SD Express cards from Western Digital/SanDisk seem to be slightly slower than that, yet still considerably faster when compared to existing SD UHS-II cards.
SD 7.1 extended Express speeds to microSD cards. Phison showed off a controller for capacities up to 512 GB:
Phison's PS5017 controller is compliant with the SD 7.1 specification, so it can be used both for SD Express and microSD Express cards. The chip supports various types of 3D TLC and 3D QLC NAND memory featuring ONFI or Toggle 2.0 interfaces, but total capacity is limited to 512 GB for some reason. Performance wise, the controller promises up to 900 MB/s sequential read speed as well as up to 500 MB/s sequential write speed, which is good enough considering types of memory that it will be used with.
It's only a matter of time before capacities hit 2 TB and above, and higher sustained read/write speeds would be appreciated.

Many years ago, one of my nuttier relatives, who is deep into fringe Christianity, and thinks she is a prophet, said that there was a 6 story building in Belgium, with 6 rooms on each floor, and 6 filing cabinets in each room (and I wondered if there were 6 drawers in each filing cabinet), in which all the personal information about everyone was being collected. Exactly what personal info this was, wasn't clear, but it sounded like name, address, phone number, date of birth, marriages, parents, and children. Pretty stodgy stuff. Apparently, DNA was not included. When this was accomplished, it would somehow cause the world to end.
I laughed, and informed her that they didn't need no 6 story building for that. A stack of CDs that one person could carry around was enough room. She got this shocked and horrified look on her face. Seems that it's all too easy for those conspiracy theorists to fall way behind.
Now it sounds like one of these new SD cards can do that job.
Anyway, at 1.44M per floppy, you'd need 750k to 800k floppies to hold a terabyte of data. Don't think that'll fit in one station wagon.

This may be a case of temporal lobe epilepsy. My maternal grandmother had it really, really bad, and she was more Catholic than the Pope, as my mother put it. Like, to the point that right before dementia and cancer took her, she told my mother to her face that "if you don't become a better Catholic, you won't be in heaven with me." And this is after my mother (and myself...) had been caring for her in her home for the better part of 5 years.

I know several Catholics that are still not totally on board with Vatican II.
They express their displeasure by going to Mass at a local church where the priest holds the service in Latin once a month or so.

There is actually a problem with the V2 mass, namely that the Quo Primum issues an anathema against its authors. And technically, the pope who did that foresaw the problems of a rite that is trying to... well I don't know what.
The mass is in Latin. So what, even in your native language we are not going to comprehend the full meaning of what is said.
The priest has his back to the people in the old Mass. So what, what's on the other side? the consecrated species maybe? oops.
In short, the V2 to me seems the initiator of a fall into chaos, more than a reaction to solve problems. From the fruits you tell the tree.

Oh yes, it's true. She never had any treatment that I know of, no. I think it very possible it could have helped her. But despite her wacky thinking, she was able to function in society well enough to get by, and stay out of the mental institutions. Actually even better than that. In a lot of ways, she's like the typical evangelical con artist who doesn't know he's a con artist. Don't think she ever tried to claim that she was the 2nd coming of Jesus Christ, or that might have been enough to persuade everyone to put her away. No odd behaviors or anything else that would immediately mark her as nuts. Had to hear her talk for a bit to learn that she was cuckoo. She didn't find Jesus until adulthood. Before that, she wasn't so nuts, though she did have a tendency to go overboard on things.
She had a teaching job in the public school system until she was fired for trying to "teach the controversy". She's an ordained reverend. I have no idea what sect. She also ran an alternative health business, which in addition to dubious drugs, included faith healing. One of the craziest of her stunts (that I heard of) was the application of faith healing to ... a lawn mower! She was also very happy and proud that she once made it into Business Week. They used a photo of her as an example of the sort of people who peddle dubious drugs for this alternative health company. That the article was extremely critical of the business, pointing out that she was basically a fraud, did not seem to matter to her in the slightest. Seems there were enough credulous religious supplicants and sick people to support her after she lost the teaching job. Still, when she visited the family, she'd come in shabby clothes and see her mother first. Her mother would be embarrassed and hastily take her shopping to buy some new clothes for her to put on so the rest of the family wouldn't see her looking so ragged.
Tragic, really. She's actually pretty smart. Baffling how she can be so stupid about reality, or more like, willfully blind. If a mind is a terrible thing to waste, she did it and how.
For those who think they're Jesus, I guess this town, heck this whole world, ain't big enough for more than one Jesus.
