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 one I was looking at was this one: 64GB MicroSD Card

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.
