Customer Ratings & Reviews

I have been enjoying this product. It's obviously not cheap but I needed a large amount of storage and this card is performing very well.

Very nice SD card with great memory and fast speeds. I bought this for my Samsung S7+ to expand the memory for pictures and 4k video. It comes with a great warranty and has performed flawlessly so far. Definitely recommend!

I’ve been watching this for months as the Price fluctuated. I jumped at the opportunity to purchase it once it hit the right price. It works great on my son’s Nintendo Switch. Would purchase another one in the future.

Great memory card. Easy to unpack and I use it daily to run my Raspberry pie. It can handle constant data flowing through.It can handle the OS running consistently and had not had one memory type issue,

So far the Extreme 512 has been prefect. I've never had any issues with any of my previous SanDisk cards, and I don't expect any issues with this one either. Currently it's being used in my note 10+ which recognized the card and has plenty of space for all of my future needs. I don't really care to use cloud storage, so having such a large card on in my phone allows me to have all my documents, music, and movies directly on my phone, with no need for an internet connection. 100% would recommend. I did manage to get this card while it was on sale, which definitely makes it worth the cost. With that said, I'm not sure if I would pay retail price for it though. For anyone wondering, after formatting there are 477GB of usable storage.

I do run and gun car videos so I am always hooking up go pros to the cars and sometimes I don't have the luxury to swap out cards or have the ability to download the footage off the card so I need to make sure I can get all the moments I need to capture and this card does the trick. With a solid read speed, I don't have to really wait too long to transfer the footage to my hard drives. Especially when recording 4k videos literally for hours the last thing I need is the card to be full during a ride-along.

I do UW photography, so I need a fast card. this one does not disappoint. It's perfect for my mirrorless Sony and then I can easily use it with my surface pro 7. Highly recommend it.

This is a great memory card. This is the ultra. You have to pay close attention because it has better stats than there non ultra which looks the same.

Very satisfied with the speed and storage capacity. I wish they were a little faster, but considering the packaging size, it is very impressive.

It holds a lot of photos. Got it for my wife's DSLR. Works great, fast, again, hold a lot more photos than the worthless 32gb one she was using form some reason.

This is great Memory card for a Dash Cam in my Semi. Record almost a full week of video in 1080p. Very hard to find extreme plus SD card. Will buy more soon

Using this product with a Skydio drone. The speed and capacity of the memory card meet the needs of the drone and me.

SanDisk is the leader in Micro SD Card Technology! Best write and read speeds and durable.

Sandisk is the way to go for high speed 4k video needs. These even work in my 5k 360 degree cameras!

Never thought I would need 512 gb for my camera, but, taking videos on an extended vacation was filling up the 256 gbs memory cards. Was at a great price to boot!

Searched out reviews for best recommended microsd card for my new Galaxy Note20 Ultra and got this one, which is highly recommended. No problems with it. Look forward to the large amount of data I can save on it!

This is a great card. The storage is awesome, the speed is great. They were awesome enough to price match a competitor so that I could buy it from them at a really nice price!

Bought this for my GoPro, holds about 12 hours of 4K footage and hasn’t crashed once.

The product is excellent. It's what I wanted and easy to use. Just don't order a product from Best Buy and have it shipped. I thought Best Buy shipping would be easy, it's not. It's the worst. Best Buy support for tracking is horrible. I am actively going through this now with Best Buy on something I ordered 6 days ago. I should have learned my lesson the first time and just went to ANY store and bought it, instead of going through Best Buy shipping.

Very spacious memory card for my Nintendo Switch. Works flawlessly, and very simple to copy over my older data from a different memory card.
