SanDisk, Nikon and Sony Develop 500MB/sec 2TB Flash Card
Lucas123 writes "SanDisk, Nikon and Sony are jointly developing a new Compact Flash card specification for the professional photography and video markets that boosts data transfer rates from 167MB/sec with today's 6.0 specification to 500MB/sec. The newly proposed specification would also offer up cards with a theoretical maximum capacity of 2TB, which would be conducive to recording high-definition video."
They didn't DEVELOP anything. They're working on the specification to allow for growth. Nothing more.
Specification... My car's tires are specified to 147mph. *Can* they go that fast?
Wake me up when there is an actual 2TB, 500MB/sec compact flash card out there. I will promptly curse you for requiring me to buy YET ANOTHER compact flash reader.
Seriously? Would you rather have 500 different chargers for every cell phone made out there? /. when the first flash memory was announced (not created or produced)- "it's only 4mb, just carry more floppies!", or "a cd can hold 700mb! And it's flat and portable!"
Having a specification is a good first step. I remember the same kind of drivel from
Seriously, you're not the target here. As stated in the summary, *professional* photographers and videographers. You know, people who rely on this shit for a living, instead of some hobby photographing flowers and pets.
I wonder how smart it is to design a spec now with the upper boundary in size equivalent to a normal hard drive. Why stop at 32bits addressing when 48 probably doesn't make much of a difference (the 16 extra will be all zero for a while after all, close to no cost on the card and negligible on the controller) and would match (s)ata that way with its far more future-proof 128PB limit.
Flash cards seem to move as fast as HDDs, they only started later.
OG.
The move from PATA to either SATA or PCIe was pretty much as expected(PATA being a dead end, development wise, and lots of pins and traces not doing your BOM costs any favors). The 2TB limit surprise me, though. Obviously, you can save a few bits here and there by reducing the maximum address size; but(by virtue of exponential growth and powers of two) you can absolutely blow the roof off the maximum size limit for just a few bits more here and there.
If this standard were promulagated in 1995 or something, when 2TB hard drives were basically science fiction, and 2TB solid state drives not the size of entire rooms and costing the GDP of one of the smaller European nations were also basically science fiction, I could understand a 2TB limit(just as the old-school sub-48-bit-LBA HDD size limits are annoying but understandable in context). However, you can buy 1TB SSDs right now. They are not cheap; but they cost less than a decent car. 2TB devices that are basically the PCBs of the 1TB devices with a cheap RAID chip in there somewhere are also in existence. If you are developing a new standard, one that completely changes the electrical substrate and will thus never be backwards compatible(unlike earlier CF standards bumps, which, with the exception of 5v/3.3v changed nothing on the physical side), why would you set a limit that will probably be exceeded in the lab inside two years, and available to the more-money-than-sense crowd in 5? Are the few extra bits that would take you from 2TB to a zillion Petabytes so expensive?) It wouldn't be cheap; but you could(using bare dice and clever stacking and the case as a heat sink) get roughly 1TB worth of flash silicon, plus a controller of some kind, into the size constraints of a CF card right now. Doubling that can't be too far away, unless we hit some nasty wall, and interconnect standards have a way of sticking around for years. Why hobble this one?
What would such a card cost? (pinky to the corner of the mouth) One BILLION dollars!
These cards will be more bulky and slower than high end SDXC cards. And SDXC is already in use today.
Why stop at just 2? Up the ante and go to 16.

2TB seems pretty pitiful for pro equipment, and 500MB/s is a complete waste for consumers.
SD(SDXC) currently maxes out at 2TB, but the first cards using the current spec shipped a year and a half ago. They can only do 104MB/sec, but it takes less than 5.5 hours to completely fill up 2TB at that speed.
I thought CompactFlash was moving over to SATA soon in the form of CFast. I know PCI-E would result it more robust IO devices but we already have a standard for that in ExpressCard.

There, fixed that for you.

Yah, like I need to be able to hold more in my megapixel camera and stuff. It already takes too long to download over USB and find the few new ones I want to put to hard drive. And I really need to spend a bunch more money on some new media, which I'll have to do if this gets adopted in anything, long before I've worn out the stuff I have. No, I don't want to say something like 640k should be enough for anybody (but with well written code, it's still not bad -- think what you can do in a dinky embedded micro). But this is just a way to make everyone have to buy it all all over again. Like the RIAA pushing new media so they could sell us the Beatles one more time, rather than find or develop another good band and take any actual risk. Oh, this time it was Apple, wasn't it. I suppose this will generate flames, so be it. Why not just take the music off one of the 45's, cassettes, vinyl, CD's etc you already own and put it on your dumb portable player you use to allow being more impolite to the people around you? Corporatism, don't get me started.
Why guess when you can know? Measure!
When are they going to switch to a different filesystem? The fat32 4GB file size limitations makes HD video a pain to deal with as well. Currently canon cameras stop recording when the file size reaches the maximum and the user has to see the recording light stop, and hit record again. A better interum solution would be to fill the 4GB file size, increment the filename by one, and keep going. I don't understand why they don't do that... it would be a simple firmware fix.
Hey, Lucas123! Just how much of a flaming dumbass are you?! Are you too stupid to know the difference between "developing a 2TB flash card" and "developing a 2TB flash card specification"? Jesus Christ! Someone ban this idiot from posting ever again. If you can't tell the difference, you shouldn't be reading SlashDot in the first place.....

Exellent card to gather more wikileaks
Well. That is actually quite fitting, since Sony is involved.
I wonder if the spec will indicate how big the rootkit will be this time...
