SanDisk Extreme 64GB SDXC Memory Card up to 90MB/s, Class 10, U3, V30

Does the job.

Does what advertised - no lag, fast data read and write, no issues with 4k and 200mbit/s recording.Haven't had a data crash so far and I'm swapping between devices quite often.One of the best priced items on a market, the usability exceeding the cost compared to other market options.Also, much more reliable than some other manufacturers- can't go wrong with SanDisk.

This is a great product. It has worked well with my Canon 750d and no problems thus far. i take my pictures in Raw format and shoot my videos in 1080P and the card holds up well in both scenarios. A realiable card that works all year round. Worth the buy!

Strange that no one has mentioned whether this SD Card is really absolutely categorically 100% waterproof !!Some other reviews comment on how 'nice' it is that it is waterproof, but so far as I can see, no-one has actually dunked it in water and seen whether it survives. Well, that's the first thing I do when I buy something which claims that it is waterproof. I drop it in water and see if it comes out OK.Well, I'm happy to report that after 30 minutes in my bathroom sink under 6 inches (15cm) of water, then 5 mins of gentle drying with a hair dryer, then 30 mins of waiting, that the SD Card sprang to life as if nothing had happened. I thought that would be useful to someone out there. I would rather know now if it is going to die (on water contact) than years down the line when it is out of warranty.Incidentally, performance is 'rather good', and actually one of the fastest SD cards I have used.Maximum Read Speed = 88MB / sec. Average Read Speed = 50 - 70MB / sec.Maximum Write Speed = 50MB / sec. Average Write Speed = 30 - 35MB / sec.Hope this helps.

Good well made memory card. And reliable , I have had no problemA with my camera while using this Memory card.

More than enough space on this SD card for filming. There would be even more if it's just for photo's. I use this for vlogging and after 30 minutes of filming I only use a fraction of the storage. Some cameras don't have internal storage so this is a must. 32 gig might be okay but I think it's a safe bet to go for the 64. 128 might be too much it all depends on what you're using it for. 64 gig is perfect for my filming and the download speed when transferring files from the SD to my computer are super quick.

Once I understood write and read speeds needed for my camera for burst and 4k video this card exceeded all the requirements without having to use PRO cards (which enable much faster data transfer).For 5 more than the the lower spec card I am now confident that my camera is working optimally.Bargain price etc. I therefore ordered two cards. One for each camera.PS 64GB devices holds more pics/video than you'd ever care to lose. Hence did not go for 128GB (which I have in my phones - for static storage).

Bought this as me and hubby went on holiday to Thailand, and we were going to see some spectacular islands etc. I wanted to ensure I had a fast acting SD card that would not delay in me taking pictures on holiday. this SD card did the job, exceptional amount of storage tot are videos and photos, and worked incredibly quick to capture images as soon as I took them. Excellent quality! Always trust Sandisk.
