My smartphone has 64GB of storage space. My laptop has 256GB, or four times as much.

But soon you’ll be able to buy a microSD card with twice as much storage as that.  Integral Memory has unveiled the first microSDXC card with 512GB of storage capacity, which ain’t half bad for a device about the size of a fingernail.

The new card meets the UHS-1 Class 1 specification and Video Speed Class 10 (V10) with read speeds up to 90 MB/s. Integral notes that write speeds are “lower,” but doesn’t say how much lower.

While there are faster storage cards available, it should be fast enough for capturing 1080p video or storing a heck of a lot of photos, videos, music, or other data. It’s the highest capacity microSD card we’ve seen since SanDisk introduced a 400GB microSDXC card last August.

Integral Memory says the new card should be available in February, and it’s appropriate for use in phones, tablets, action cameras, drones, and home security cameras, among other things. There’s no word on how much the new storage card will cost, but “a lot” seems like a safe bet.

    1. “should” is a very flexible word. See my comment above about the Sony Xperia Z5 Compact running Android 7.1.1…

  1. Can we all just take a moment and think about how much storage we can put in such a tiny card? My first hard drive was a full height, 10 MB (yes, megabyte) drive. We are approaching the point where technology is becoming magic.

  2. That’s nice, but I’d rather nit store important data on a high capacity SD card. Only one NAND chip, a very basic controller and no overprovisionong. These devices tend to fail the number of failed (quality) 64GB microsds in my drawer alone add up to more then 512GB. What I learned is that they are fine as long as you fill them up about 10-20 times, but they becone a liability after that.

    I use a 128gb one in my GPD win to install games on, as it would fill it up 3-4 times in it’s lifecycle, and another 64gb obe to carry around movies. But I had my fair share of failed sd’s from drones, cameras, gopros and such.

  3. Never heard of Integral Memory. Not sure I’d risk losing up to 512 GB of my data on a card from this company.

    1. They have been around since the days of 128MB flash drives. We use a lot of them at work and have never had any issues.

    2. They have been one of the bigger players for a while. Together with Kingston, SanDisk, Transcend, Samsung and Toshiba and a few I might have left out.

  4. the capacities keep on rising but the prices of the lower card are not dropping
    like they used to
    128gb cards are actually more $$ now than they were a year ago
    it used to be that when the storage doubled the price of the other lower cards was cut in half , now not only are the prices not dropping they are actually increasing

  5. I’d love to see a 4-8 TBs built into a watch – slim, not like those “smartwatch” bricks. Maybe add WiFi, in addition to microUSB-style connection. Partition a couple of slices up front for emergency bootable2ram OSes – the rest of the space for data storage.

    512gb is nice but it’s still in that middle ground area of usefulness.

      1. Or approximately 500 feature length films at DVD resolution, likely higher quality than you can see on a watch.
        Or about 80 operating system ISOs, again more than the watch can use.
        “Useful” is a fluffy term.

      1. If there’s a limit, it’s purely artificial and dictated by crappy software. 512 GB card does not differ from 256 or 400 GB card in any way except that it has more blocks.

    1. Many phones don’t have SD card slots. Those that have, don’t have any hardware related issues supporting more. The card is physically the same. Just more logical blocks. I have 256 GB cards that work just fine on many devices.

      1. Some Android phones state a 32GB limit which sounds like they might have a software issue.

        1. The 32GB limit is for the SDHC specification. Any device that supports the SDXC specification should be able to read cards up to 2 TB.

      2. My SanDisk 128 GB µSDXC card works wonderfully in my Sony Xperia Z5 compact runnind Android 7.1.1. My Samsung 256 GB not so much. Neither on the Xperia Z1 Ultra. I also understand that the SDXC standard should crap out way beyond the TB limit, so I am a little pissed.

      1. Moto Z2 phones can take microSDXC up to 2 TB. Other Moto phones may also be able to handle that capacity. The Ockel Sirius A palmtop (6″ screen Win 10), crowdfunding on Indiegogo, can also handle microSDXC up to 2 TB.

    2. Not true. Moto Z2 phones can take microSDXC up to 2 TB. The Ockel Sirius A palmtop (6″ screen Win 10), crowdfunding on Indiegogo, can also handle microSDXC up to 2 TB.
