The ‘Virtually Unbreakable’ SD Card Line

By Kishore Sawh on October 17th 2014


Amidst the triumphant chaos of a revved up Apple crowd, other gear announcements were made yesterday that weren’t revealed at a predictable, almost antiseptic, albeit good, keynote. Delkin Devices somewhat quietly launched their new line of SD memory cards with the promise they will be virtually indestructible.

As the key to skipping a stone apparently lie in the wrist, apparently, the key to this new line of SD cards is all in the case. The casing of the cards are built using a type of proprietary injection molding process which is much different from the typical welded design. The material itself that’s used is also atypical, and all of this has given Delkin the ability to market this new ‘Black’ line waterproof even if submerged for 72 hours, disproof, shockproof, and extremely temperature resistant, effectively making them unbreakable as suggested by Delkin’s Marketing Director, Anna Lopez:

From the Arctic to the Sahara, and even through your washing machine, the unique design enables Delkin BLACK cards to perform through hazardous environments and remain totally usable without experiencing any data loss. And perform they can, with 99MB/s read and 80MB/s write speeds. This makes them sufficient for 4K shooting.

Perhaps just as notable a feat as building a card this rugged is, the alleged service that’s being touted with it may be even more impressive. Due to the faith placed in the Black line and it’s rugged, brutish ways, Delkin is offering an unprecedented 48 hour, no-questions asked card replacement program.

Anna Lopez continues to inform that this covers you entirely from any possible issue that could arise, from gum in the pocket, to your card being left in pants and ending up in the laundry machine, and all that’s required to get a new card is a phone call, after which your card will be received by you within 48 hours along with a pre-paid envelope for returning the corrupt card.

The service does sounds impressive, and the cards just as much so. The question being raised by many right now, especially those who have watched the video here, is how many people are actually there subjecting their cards to this level of torture, and breaking them?
If you are interested in purchasing the cards, you may do so only in store, since as of this writing they are not available online. To find out more, please do visit Delkin’s official site.

    I left my cheap SD card from my backyard motion capture camera in my jeans pocket. It survived both the washing machine and the tumble-dryer.

    This is great. If you have to ask why anyone would need these, then obviously you don’t need it.

    Get a product in which data doesn’t corrupt.
    rest we don’t need hardness factor . We are not gonna fight with our cards

    I think this is just another type of hype. I’ve never had a memory card physically break. I have had some become un-usable after long and heavy use in the camera, or computer. I looked at the Delkin site, and used the dealer look-up, and did not find a dealer anywhere near where I live. Adorama, and B&H were listed, but I could not find the Delkin Black SD card listed yet. I’m really not in the market for a SD card presently, but who knows lightning may strike. I did find a site called “” and looked up “sluggish and error prone SD card, for a friend. The site had plenty of information on how to resurrect a corrupt, or damaged card using Windows, and also a site for the SD card developers.

    I see a lot of people always saying their SD cards get corrupted. One thing to do to your SD cards if this is a problem you are finding is a full format or overwrite format. I’m not talking about a format in your camera, I mean a full extended format where the entire cards gets erased. This is something that you have to do every so often. For most people, you’ll have to do a for format about once a year. If you’re really busy shooting then probably twice a years is better. The SD Association at has a free formatter available for Windows and Macs.
    Hope this helps.

    It is very good to have very durable cards. The idea is to have the internal structure durable as well. What is the gain you have an unbreakable card if the data get corrupt?

    Looking forward to trying these out, generally I’m pretty careful with my cards but I have knacked a few over the years.

    This test is cool and everything, but what I would be most concerned about is if the little plastic teeth on them are more durable, or if the freaking top plastic cover plate doesn’t come off like my last sandisk card did and make it unable to insert into my camera. That is the real test to me.

    Long overdue…I also agree with Brandon. I’ve had more SD cards become corrupt than break – lthough my last SD card somehow just fell apart :(

    Being durable is good but it would be a lot better if it was non corruptible. I have never had a memory card break but i have and a few stop working because they some how got corrupted.

      Exactly!!! I had to buy two recovery programs once just to be able to have a CHANCE to get them back once. (I recovered some of them)
      Besides… those numbers…. It’s such a small object, that unless it falls flat on the street and American truck runs over it loaded with heavy machinery, I don’t think just dropping it to the ground is going to “break” it.
      Think logical for a minute, there are physical rules that imply so being breakable is the least of our worries here. (getting wet on the other hand…)
