Review: Compatible with everything I've tried and super fast for 4k Video! - Bought this for my Paralenz underwater camera that shoots up to 4K 30fps. My camera manufacturer says 128gb V30 is the required max but this card is rated for a min of 10mb/sec & and the write speed is undocumented publicly after contacting Sandisk, with transfer speeds to 100mb/sec. Maybe they won't release write speeds because it performs so well they don't want it competing with their faster rated cards?.... just speculation of course! But this card performs flawless... not only in my Galaxy Note 4 phone but also in my camera. Leave it formatted in the default exFat and your good! After much research it appears its only weakness may be in burst abilities for use as internal memory but sustained transfer rates are great!... so much so that 4k @ 30fps video was no problem in testing. I'm also astonished this card works so well in my Note 4, I had a 128gb Sandisk in before and this definitely feels faster. At this point I have the highest recommendations for this card.... you can now store mass amounts of 4K footage.... according to my tests so far, about 10+ Hrs of 4K @ 30 fps! I've found other brands often give similar speeds as compared to Sandisk but fail miserably long term in reliability.... Do you really want 400 GB worth of stuff lost because you wanted to save a few bucks with another brand? Sandisk is the most reliable IMO and it's amazing they remain at the front of the pack. It's not the fastest dog out of the gate that wins, but the one who can make it to the finish line first! I own 3 of these now. I can film 2.7k @ 60fps and put 17 one hour dives in a week long dive vacation and I only use about 180gig! Its great not having to tote a big laptop on my trips! I have one just for backup too on my trips .. Haven't had to use it yet! Review: Nearly "unlimited" storage, works well on a Samsung Note 9 - Summary: the SanDisk Ultra 400GB seamlessly adds what amounts to unlimited storage for your phone. I've had it installed and working well on a Samsung Note 9 for the last three months. After putting the SanDisk Ultra 400GB in place on my Samsung Note 9 , I don't think I'll ever run out of space on my phone. I love this: I never really have to download pictures or video from my phone, and I can permanently store whatever movies, documents, or other files I wish. Even after shooting thousands of photos and hours of video, I have hundreds of gigabytes of free space left. On the Samsung Note 9, the 400GB card reports 366.8 GB of free space after formatting. Using a speed testing application, my card reports write speeds of 48 MB/s and read speeds of 86 MB/s. Suggestions: * After purchase, get an SD card speed testing application to verify that your card isn't fake, and that its performance approaches SanDisk's hyped theoretical maximum. Don't be put off if you don't reach 100 MB/s or whatever the advertised maximum speed might be; you just want to be somewhere in the ballpark. If you are using Android, you can download an excellent SD cart-testing application from the Play store called "SD Card Test." * On some Android devices you can further verify that you have a legitimate (not fake) card by downloading an application called SD Insight (note this app is not compatible with the Galaxy Note 9 and some other late-model Android devices.) note: I was *not* solicited to write this review, and I bought this product with my own money. I received no compensation for this review and indeed I have no idea who the seller might be. I pride myself on writing unbiased reviews. ## Features - Ideal for Android smartphones and tablets, and MIL cameras - Capacities up to 512GB (1GB=1,000,000,000 bytes. Actual user storage less.) to store even more hours of Full HD video (Approximations; results and Full HD (1920x1080) video support may vary based on host device, file attributes and other factors.) - Up to 100MB/s transfer read speed (Based on internal testing; performance may be lower depending on host device, interface, usage conditions and other factors.) lets you move up to 1000 photos in a minute (Based on 4.1GB transfer of photos (Avg file 3.5MB) with USB 3.0 reader. Results may vary based on host device, file attributes and other factors.) - Load apps faster with A1-rated performance (A1 performances is 1500 read IOPS, 500 write IOPS. Based on internal testing.

Should work in any camera that requires a Class 10 Micro SD card. I do not have a GoPro but if it asks for a class 10 Micro SD, it will work. **Q: Is the 400GB sd card compatiable with surface pro 4?** A: Yes it will. The tablet is capable of using a large SD card like that. I am currently using a Microsoft Surface Pro 2017 and I have an 128GB SD card installed in it and it works fine. I don't know where you would be getting a 400GB SD card. You might as well buy a 1TB SD card for your Surface Pro 4. There's no reason why you would need a 400GB SD card unless you're using a lot of apps that are for art or large PDF files. My Surface Pro 2017 came with 1TB of Onedrive free so I'm not really concerned with the memory bc all my customer's docs are saved on Onedrive so I can access it at work and at home when I need it. I rarely every even use the SD card and 128GB is enough for most people and most cases. **Q: Does this work on a OnePlus 7 device?** A: OnePlus phones never had micro SD card support. I understand the OnePlus 7 series is no exception. OnePlus claims that micro SD are slower. Thus it will have an effect on phone Performance. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Compatible with everything I've tried and super fast for 4k Video! *by A***. on April 24, 2018* Bought this for my Paralenz underwater camera that shoots up to 4K 30fps.

Fast enough that I can throw pretty much anything at it. If you're wondering, modern Android versions (starting with Lollipop, as I recall) have the ability to read up to 1 TB of external storage. While this 400GB card is the maximum capacity you can currently buy*, the leading manufacturers are feverishly working to make larger capacity cards. For now, though, I think 400GB is enough to handle all the 4K video I can shoot. *- Don't be fooled by unscrupulous sellers, particularly on auction sites ( I won't name it because there are a lot of fake cards here, too), who list ridiculously large capacity cards for astonishingly low prices... you don't get what you pay for! They take cheap, generic cards, usually no more than 4 or 8 GB, and rewrite the card's firmware & re-label it to make it act and appear like a larger card... 256GB, 500GB or higher! There are tons of listings out there for 1 TERABYTE microSD cards! Of course there's no such thing: and when the physical memory of the card is reached, your device will simply start overwriting data... and your precious photos, videos and other files will be gone forever. In fact, one third of all SanDisk cards on the market are counterfeit! You can avoid all this by installing and using a free app called SD Insight to determine if your card is legitimate. ## Frequently Bought Together - SanDisk 400GB Ultra MicroSDXC UHS-I Memory Card with Adapter - 100MB/s, C10, U1, Full HD, A1, Micro SD Card - SDSQUAR-400G-GN6MA - Funturbo Ultimate Version SD2Vita 5.0 Memory Card Adapter, PS Vita PSVSD Micro SD Adapter PSV 1000/2000 PSTV FW 3.60 HENkaku Enso System --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/46095819-sandisk-400gb-ultra-microsdxc-uhs-i-memory-card-with-adapter](https://www.desertcart.com.pa/products/46095819-sandisk-400gb-ultra-microsdxc-uhs-i-memory-card-with-adapter) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-10-12*
