SanDisk Releases 512GB SD Card 210

Lucas123 writes: SanDisk has announced the world's highest capacity SD card, a 512GB model that represents a 1,000-fold increase over the company's first 512MB card that it shipped a decade ago. The SanDisk Extreme PRO SDXC UHS-I memory card has a max read/write rate of 95MB/s and 90MB/s, respectively. The card is rated to function in temperatures from -13 to 185 degrees Fahrenheit. The 512GB model retails for $800. The card also comes in 128GB and 256GB capacities.

  • And now we have a decent sized amount of space for digital video. Huzzah!
  • Just how many Libraries of Congress are we talking about, here?

      Dunno about LoC's but this is equal to about a single Archos 5.

      When these prices come down, I will finally have a reason to retire the old thing (my Archos 5).

    • 1/1075th of one LoC [google.com], given the numbers in this [wikipedia.org] Wikipedia article and extrapolating from its information:

      Library data: The U.S. Library of Congress Web Capture team claims that "as of March 2014, the Library has collected about 525 terabytes of web archive data" and that it adds about 5 terabytes per month

      525 tb + 5 months of 5 tb / month = 550 tb.

      (Not counting September as completed, so only April through August.)

      Or, you'd need a stack of 1,075 of these SD cards to hold one LoC. (The actual calculation is

      • ...in a decade or so 1 LoC will fit on a 1 portable memory device the size of a postage stamp?

        I mean... only a decade or so ago 1 portable memory device the size of a postage stamp had about 1000 times smaller capacity.

        Which means that we'll finally be able to use LoCs as a practical measure of size, distance, speed, weight...

    • I still think in terms of double-sided Commodore 64 5-1/4" floppies. At about 320KB per disk, that'd be 1,388,888 disks.

    So the highest MP camera I could find in a normal store is 40 Mpix (Pentax 645D) * 14 bit RAW = 70MB/picture. So good for 70,000+ photos. Or the Panasonic HC-X1000 4K/24 & UHD/60p camera just released, 150 Mbps = 7-8 hours continuous recording. But I suppose it's good for when you want to carry 10 BluRays in your phone. Whoops, wrong format not microSDXC. I guess there's a niche for this since they made it, but I kinda fail to see the target market, unless it's the "give me the biggest and best you got"

      How is 640kb of ram working out for you?

    • Son, the pixels arent 14-bits each. They are 42 bits each, which is rounded to 48 bits each. 6 bytes per pixel.
    • I guess there's a niche for this since they made it, but I kinda fail to see the target market, unless it's the "give me the biggest and best you got" crowd.

      I can imagine plenty of uses for this in automated systems such as video system or other data gatherer. And even if it's to be used to record manually-triggered output, there's much to be said for the concept of "so much freaking storage that I can pay for this once and never have to think about it again over the lifetime of the equipment I'm using it with".

    • 4K camcorders!
    • The largest files you can get from a camera are TIFF not RAW, and thus you'd be looking at 40Mpix * 16bit per pixel per channel (remember a final image is per channel, the RAW has a beyer matrix) * 3 channels = 240MB/picture. That's only 2200 photos on your super memory card now.

      Why would you shoot in TIFF? Production ready from the camera. If you shoot at an event you can use the camera to process the image and then save an uncompressed file ready for print / transmission. Kind of important if you want to

      8k UHD video does exist... NHK in Japan was broadcasting the Olympics in 2012 at 8k resolution in Akihabara. There's always a need for more capacity.

      "But why, some say, the moon? Why choose this as our goal? And they may well ask why climb the highest mountain? Why, 35 years ago, fly the Atlantic? Why does Rice play Texas? We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone,

    • There is a target market for everything.

      For example, a high end graphics card can be called overkill, until you bring in gaming.

      So who shoots 70000 pics? Well for one, us timelapse folks. often to get a 30fps, a 10 minute time lapse means 600 seconds = 18000 frames.

      This is just a 10 minute sequence.
      Then there are the sports guys. Often each shot is a 80 frame sequence, then pick out the best. Again, one day means 15-20000 pics. Many shoot RAW+JPEG, so that is going to increase the space.

    SanDisk if you are reading this please make a 512GB Micro SD... thanks!!

    All that in a standard 1 1/4 x 1 inch package. Amazing.

  • Too bad Google crippled SD cards in Android so they can sell cloud services.
    Too bad tablets and phones don't use SD cards.
    To bad too many companies make SD cards that stick out.

    • Your comment is slightly off-topic since this SD card is of the regular size and thus doesn't fit in smartphones...but otherwise I completely agree with you. Why is everyone so intent in robbing us the ability to manage storage in our smartphones? :(

    The new GoPro camera...which hasn't come out yet...is said to effectively capture video at double the rate that it currently does. So it can do 1080p at 120 frames/second.

    But there's a problem with that...the existing GoPro, at half that speed, requires the very fastest of SD cards (UHS Speed Class 3) to be able to write the data fast enough. So I was wondering how the hell the camera would even be able to work at 120 fps 1080p resolution in the first place. This card, with its throughput, answers that, since it's triple the UHS Speed Class 3 specification.
