Review: We're Finally at About Half a Gb for Micro Storage! Yea! - This card has not disappointed me yet. With huge amounts of space, and a transfer read speed listed at 100MB/s, it's a card that can serve all kinds of purposes—assuming your device supports this storage amount—for photos, music, videos, and just plain old file storage. I am using mine with the new Sony NW-A45/L Walkman with Hi-Res Audio, Moonlit Blue (2018 Model) , and it has worked marvelously so far, with all the memory being "seen" by the player, and some very good transfer speeds. I have not yet specifically tested the actual speed, but will do so soon with the Black Magic speed tester, and will update this review with that report. Right now (mid-2018) this card is running at just under $200. I don't suspect it will drop anytime soon, since its the only guy on the block, so if you have a use for it, you might as well get it now. I doubt this will even be marked down much towards the end of the year, although I could be wrong, due to its unique status. Having said that, if the price is still too high, keep an eye on it, because there MAY be occasional rebates, two-day sales, etc. It has all the standard SanDisk hallmarks: high quality, nice look, good performance, nice looks, and it, of course, comes with an adapter in case you wish to use this in a camera that takes the standard sized SDXC cards. I can put almost my entire lossless audio library on this one card, which is amazing. Five stars, and an update soon with the results of the speed test I plan to perform.
Review: Lots of storage (400GB) and impressive speed from SanDisk, a trusted brand - Not much to say other than to remark on the validity of the SD card I received through desertcart actually being from SanDisk. SanDisk is one of, if not the biggest, SD card manufacturer and the quality of their products is the golden standard. So capacity, performance, and reliability goes without saying for these SD cards. However, I have read quite a lot of reviews claiming that the ones they received were imposters and, while I do not claim they are mistaken or not, I can say that my 400GB one I received from desertcart seems to check out through every test I've run it through. desertcart has quality customer care and product replacement/return policies for the ginormous corporation they are, so if you have any issues with your product I'm sure you can get it worked out within reason. There are a lot of different resources for checking the validity of SD cards online and you can find them all with a simple search on a quality search engine website. If you are concerned, I suggest going that route or contacting local IT support to see what they can do for you. PROS: SanDisk. Enough said. Quality and performance. CONS: Obviously, verrry slim chance of the SD card being a fake. Technology is amazing these days and there are people out there driven to make a quick buck if they've got the materials and the know-how. Even giants like desertcart can fall victim to these numerous and unethical kinds of practices. Happy with my purchase. 100% 400GB SanDisk SD card at a reasonable price.

## Questions & Answers

**Q: Does this work with the samsung Galaxy S8+?**
A: Yes, Samsung s8 and s8+ aswell as the note 8  can technically read up to 2TB I have use my 2tb external hard drive with it all the time

**Q: Does this work with gopro?**
A: It is a class 10 card.  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.

### ⭐⭐⭐⭐⭐ 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. 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!
