Samsung launches a fleet of fast, tiny UFS memory cards

Samsung's recent advances in the storage front have been nothing short of impressive. Not that long ago, the company announced a single-BGA-package NVMe SSD. Now, the company's storage division is at it again with its new UFS memory cards. While these slivers of storage may resemble microSD cards, they're actually a new standard that will likely require new slots or adapters to be useful.

The new cards support the JEDEC "UFS Card Extension Standard," which means they're quite a bit faster than even the UHS-II microSD card standard. Samsung says the cards have a sequential read speed of up to 530 MB/s, while sequential writes can go as high as 170 MB/s. According to the company, those figures make the UFS cards about five times faster than a "typical" microSD card.

The sequential operation numbers are impressive on their own, but the random I/O figures are even more so. Samsung says the UFS beasties can execute up to 40,000 random read IOPS as well as 35,000 random write IOPS. As a point of comparison, Samsung says a regular UHS-1 microSD card can do about 1,800 random read IOPs and a paltry 100 random write IOPs. The company envisions these cards inside drones as well as DSLR, 3D, and VR cameras. Capacities range from 32GB all the way to 256GB.

Updated 7/8/2016 at 8:36 AM to clarify that UFS and microSD are competing standards with different physical requirements.

    Phone OEM: “That’s cute. Would be a shame if we continued to refuse to allow any external storage devices to be attached to the phone unless if they’re using cloud storage. 16GB or 32GB for an extra $100!

    64GB internal storage? Hah, no.”

      BUY A LUMIA 950

      I ended up purchasing the phone I have now specifically for the SD slot.

    ” they’re actually a new standard that will likely require new slots or adapters”

    nothing a hammer and flat head screwdriver cant fix.

    It’s going to be a pain for the next couple of years carefully reading the SD Slot specs on every new device to see if this standard is supported or not.

      Manufacturers: “Don’t worry we’ll make it easy by removing all external slots”

        Ain’t that the truth.

    Looking forward to a Lexar ‘Happy Days’ branded UFS card with a picture of the Fonz on it.
    Now that’s what I’d call a Jump Drive! Although this time with the shark jumping the Fonz. 🙂

      How about the Van Halen 5150 Jump! drive with a picture of spandex-clad David Lee Roth on it?

    Because why shouldn’t we have yet another incompatible standard?

      • smilingcrow

      Because it’s necessary at times to break through the limitations of old standards.
      Which is why SATA has been eclipsed by PCIe M.2 cards for high performing SSDs.
      Backward compatibility is great up to a certain point and then becomes a hindrance.
      In this case the performance jump makes a new standard acceptable to me.

        Yeah, when current microSD cards are doing 90-100MB/s max, 500MB/s is quite a jump.

        [Add] This does make me wonder how they accomplished this though. SSDs make use of multiple NAND chips in parallel to achieve the same speeds. Surely there isn’t much area for parallelism on a chip the size of your pinky fingernail.

      UFS isn’t completely “new.” Some phones are using the technology internally. What is new is the form factor for removable media.

    These are probably the best things you could use for Portable Storage in Android 6, but Samsung’s own phones don’t support that feature.
