I'm planning on getting a 64gb microSD card (Sandisk) from Amazon for my Galaxy Note and was wondering is the speed factor the only difference between the class 6 and class 10 with uhs-1?

Class is not the best indicator. Get benchmarks/a review:




In general:
High class = high sequential IO
Low class = high random IO

You want to strike a balance between the two. The sandisk mobile ultra UHS-1 class 10 does this nicely.
Three cards i tested, top is 50mb of transfer, bottom is 500mb of transfer:

Also by the looks of the reviews on amazon of that card, some people have been sold lemons. Are you saving much by buying overseas compared to NZ

The benchmark result had the read speed capped at 20 MB/s and likely using USB 2.0

main benefit of UHS-1 is read speed over USB 3.0 afaik. It could go as fast as (claimed) 90 MB/s, benefiting ppl move huge video and picture files from media to PC/mac.

HD video recording recommends minimum class 4, with 1080p 50p writing just under 3 MB/s, class 4 is borderline ok - but some class 4 could do much more than that, and some class 4 could hardly keep up with 4 MB/s.

Depends on what you doing with the card, you may not feel a huge difference using it as a storage (play MP3 for example) between a class 6 and a class 10 UHS-1 from the same brand.

Seeing that the class 10 is only a few bucks more expensive than class 6, i see no reason why not go with class 10.

Thats the one I read too, and there is quite a high percentage only giving it 1 star.

I'd say pay the money and get a UHS-1 SanDisk card. Then it's a keeper for a future exFAT capable phone.

The following is what you get on Win7 notebook with a SDcard reader when benchmarking a SanDisk Ultra Mobile 32GB UHS-1.

Get a lot less on my phone, with seq write at ~6.5MB/sec and seq read at ~17MB/sec, but it's an old phone (Sony Ericsson X10i)



Interestingly, in a lot of the old phones, the SDcard at Class4 or greater will probably be faster than the read rate of internal memory.
