There are also 128GB and 256GB models available...
... if you're not ready to spend $800 for a SD card.
It's a pity there's not yet a micro SD one available, though...
Barely a decade after releasing its first 512MB SD card, SanDisk has unveiled a card capable of storing 512GB of digital material. The Extreme PRO SDXC UHS-I memory card can write at 90MB/s and read at 95MB/s; not the speediest if you need to shift half a terabyte in a hurry, but enough it seems for recording 4K video straight …
'never underestimate the bandwidth of a station wagon filled with tape'.
Fill a station wagon with these things and I think you'd have a world bandwidth record for a Sneakernet variant...
Progress - I can remember when the idea of a 10gb HDD, never mind a 500gb HDD, seemed like the fever dreams of a madman. That was only fifteen or twenty years ago as I recall (I had a 120mb HDD back then).
Now you can get that sort of capacity in something smaller than your thumbnail - and it has reasonable bandwidth too (OK, SSDs are ten times faster, but when you take access times into account, that likely wouldn't be any slower than a chunk of spinning rust)
Gobsmacking.
Can all you "i had a 10Mb hdd (copied from wikipedia)" ... shut the F**** up... your dad had 512kb sdcard/hdd and that was enough for him ... and his dad had 512 bytes of sdcard/hdd and that was enough for him ... and his dad had 512bits of sdcard/hdd and that was enough for him... you child will have a 512TB of sdcard/hdd and it will barely be enough for him.
I remember having to unzip the Doom folder to play it and then rezip it when I'd finished on my 120MB HDD.
I thought technology had reached its peak when I bought my first 64MB USB stick and cold finally start to think about leaving my parallel and serial link cables and Laplink V.1 floppy at home.
For your entertainment, on the computer noted above, I got some OS/2 install disks, and tried to install it before I had removed/unconfigured doublespace (or whatever it was).
Cue one wrecked file table, and being about twelve, skint, and living in a tiny village where I was the only person with any real computer chops, that was the computer dead.
Bah.

Things they never say - what pressure are the tires are inflated to? A typical "monster" truck weighs 5-6 tons but the tires are typically only 15 psi and for water fording events they drop it to 5 psi. Total force on an SD card at the higher pressure would be about 19 pounds so it's less than the ~27 pound average for a 2 year old by a substantial margin.
Don't know about the SD card, but I had a Cruzer 16GB USB stick go through an 80deg C wash/spin cycle and it still works 2 years later.
My first HDD was 20M but my purchase of an 80M brought tears to my eyes (and wallet) !
One wonders how long the increases can continue ?
I say with 3D flash on the cards, there's a likelihood of SDXC hitting the 2TB capacity limit in a few years. At which point SD will need to figure out which letter to use next for the next capacity specification. And let's hope this time they settle for a less-encumbered filesystem (though for lack of ubiquitous alternatives, my money for now's on NTFS--any other format and Windows will need a filesystem driver).
It's a bad idea to use one of these cards by itself for storage. If it becomes corrupted, you lose a whole bunch of data at once. I wonder why most cameras don't support dual mirrored card slots. If your use case depends on a high end camera and a big SD card, surely you need live data replication as well.
> I wonder why most cameras don't support dual mirrored card slots.
It's simply not a big problem. There aren't enough people being burned by this and an insufficient number of paranoids to bridge the difference. Plus these devices are generally not archival storage anyways. They're very temporary. This stuff gets quickly dumped somewhere else.
Multiple card slots might make sense for increasing total storage.
Don't see a lot of people calling for RAID on consumer appliances though.
Professional photographers will typically use a fresh card every shoot and never delete anything off of it. Cards are so cheap that they either just swallow the cost of new cards or charge them to the client. The card would then be set to read-only and kept in a file box somewhere for the remainder of time (mostly as a secondary back-up). That and professional photographers will carry two cameras anyway to prevent data loss form corrupted cards and a whole host of other potential issues.
Do we? News to me. Never seen anyone do that at all.
SD cards are not an archival format. Additionally cards are most likely to fail when new. Most people are happier shooting to cards they know are good and then replace them every year or so depending on the duty cycle.
I still have an couple of 5 year old cards being used but the duty cycle for them has been very low.
There are a couple of options. You have SD cards with built in WiFi that can mirror to any android or ios device. You also used to be able to get external card reader + hdd with a one button "clone what's on this card to the HDD" button. I had one about 10 years ago when a 512MB CF card cost would empty your wallet with around 40GB on the HDD.
"It's a bad idea to use one of these cards by itself for storage."
Most savvy users realize this. The SD card is meant as a transport medium, not a storage medium, though one exception is phones and tablets, where Micro SD becomes a storage medium for noncritical or backup data.
In any event, the idea is the SD card is only used as a temporary hold for a recording/shooting session. In my case, when I get back to "base," one of the first things I do is take out the card and insert it into my laptop's SD slot, whereupon I offload the contents to a more-permanent storage device. I organize simply by dumping each session into a folder with the date on it. Once it's done and verified, I can slap the card back in the camera, wipe it, and be ready for the next session. And just in case one wears out, I keep a second one as a fallback. By the time it wears out, I'll have already bought a replacement.
>"there's more to come. In the past SanDisk has said that the firm isn't even close to the limits of the form factor and it plans SD cards which will hold up to two terabytes"
It's close to the limits of SDXC, which is 2 terabytes - so two doublings of where they are now... If Moore's law* still holds true, and assuming 512GB is the highest density they can cram in now, they'll be at SDXC capacity in 3 years.
* - for pedants, the refinement from David House as 18 months seems to hold truer.
By the time my 16 Gb SD cards in 3 disk rotation start wearing out (3 years from now) the price for 3 will be just about what i paid for my 16 Gb SD cards (w/35 Mb/sec transfer rate)... these new puppies exceed the 73 Mb/sec rate of my Samsung EVO SSD...YUM.
IMHO= 3 years from now Staples will have 3 for under USD. $200.00...RS.
At least one reason was the part/model number - 3030.
The biggest problem was training ops to NOT swap a disk to another spindle if they had a problem. I saw four sets of heads gone before the op twigged it was a faulty disk.
Also working amongest the drives you could get bumped as MVT decided to open a drawer to swap disks for an upcoming job.
