SDHC and SDXC aren't associated with speeds, they are associated with the volume of storage only, i.e. 64GB is SDXC, anything below that like 32GB is SDHC. Most devices nowadays are compatible with SDXC, but many older devices and low end devices might not accept cards above 32GB.

In terms of speeds, and especially when looking for something capable of coping with Android's adoptable storage, you need something with UHS 3 speeds. To determine the speed of a card, using just the Class of it is no longer really appropriate. Just look for UHS 3 and you'll be fine.

The Toshiba M302 microSD cards are UHS 3 and are quite cheap.

received my M302 yesterday and moved apps on to it. the apps load a lot quicker from the memory card compared to my previous Lexar class 10. a good app I use to benchmark is 9Gag, on my Lexar card the app would just freeze for a minute or two on a black screen before it responded (similar waiting time with Autotrader and other apps). on this M302 card, they load up after a couple seconds! thanks again for the recommendation.

Comes up now @ £10.95 delivered before the code. Has this price expired?

Thanks OP I just ordered 2 for £16 for our Samsung mobile phones! Free shipping is good too.

(Slightly out of topic -but when I purchased them and paid by Paypal, "Google Free Protection" thingy popped up
which I have not seeng it before...
but since I thought Papal purchase is pretty much protected up to certain price, I just declined it.)

Now it says £10.95 ?
but when I place 2 of them in shopping cart total shows £16.00 which I don't mind and I was gonna need 2 anyway.

Will this Sd card work with a kitvision Splash action camera???

Thanks OP. I didn't need it until I got sent two Pi Zero W's by mistake so needed another card ;D

These work fine in my GoPro4 I always record at 1080 never found a use for 4K recordings 1080 is more than enough unless you have a huge cinema.

2 for £16.00 and free delivery

anyone got true read and write speeds?

Would the toshiba be good enough for my nvidia shield or would I need a faster speed?

Pay the extra £1.50 and have one that will still work above 1080p

Ah, so my UHS-1 Samsung 128gb card needs replacing to speed up my phone? I'm not using adoptable storage but have apps on SD so probably worthwhile

is this any good for an android phone?

Can I use this in a GoPro or do i need a faster card

Just FYI just about to buy this for my GoPro and I don't think the read write speeds are good enough

​Would always opt for Amazon over anyone else if there's just a couple of pence in it. Their customer service and returns policy are second to none.

Cant get code to work

*looks at pictures first. Assumes 300gb for £8.54.* :disappointed:

Thanks, I've just ordered 2 for £16. Paid with PayPal two so don't get charged for two weeks which can be handy for some.

Nice price, ordered one, thanks for share!

8.99 at Amazon

Fantastic deal. Just what the kids need for their SKY3DS+. Many thanks.

That's some good advice the pair of you. :-)

Thanks for the info dudes. Saved me wasting a tenner. ​
found a M302 here on back order for 10£ https://www.amazon.co.uk/gp/product/B01EAKB3L0/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A3P5ROKL5A1OLE

great advice. look for a U on the card with a number 3 inside as all UHS 3 cards will hae this. Most type 10 will have a U with a 1 inside these have a minimum speed 1/3rd that of the USA. no number in a U always means slow.

is SDHC faster than a normal class 10?
I have a class 10 32gb in my phone but the apps that are stored on the card memory take an age to load (moto g4) sometimes just unusable.

Paid £12.99 with MyMemory 2 weeks ago for a similar card!!!!
