Cards Tested
Samsung Evo+ 64GB 80MB Read/ 20MB Write MSRP:20$
Samsung Pro 32GB 90MB Read/80MB Write:20$


Handheld Used
JAPN3DS Emunand 10.7 CFW Aureinand 5.1.2

Going into this test i obviously thought the Pro would be faster in terms of installing cia's booting into emunand etc but that wasn't the case in some of the outcomes seen below.
the test cia i chose to use was a pacman game i had dumped prior to this test which ended up being around 160MB's in size.

Samsung Pro (UHS-3)
Boot(Emunand) : 8s
Cia install time : 1m56s
Title launch : 8s


Samsung Evo+ (UHS-1)
Boot(Emunand) : 11s
Cia install time : 1m13s
Title launch : 7s

So we can see here for the same price as the pro the evo has a faster install time and a faster title launch via emunand compared to the pro but lacks a 3sec delay when booting into emunand.

Well you are comparing the Evo+ with the old Pro. You should also be comparing similar sizes as each can possibly be using a higher or lower number of sectors.

You should be doing Pro+ with Evo+, I've noticed fairly similar times.

Though hands-down the Pro+ wins in sheer time saved. Try moving 50GB of data to each card.
The Pro+ will top out at 70-80 MB/s, whereas the evo will top 20MB.

Evo+ Tops at 24MB/s when moving large cia's
Pro Tops at 78MB/s Moving the same file

judging by the specs even if the pro was older using a higher standard UHS-3 , theoretically speaking it should have been faster overall.

Possibly, you should also post the specs of the format itself (16, 32, 64k clusters) etc...

Also, post some test from D9 showing NAND dump speeds. I'd be interested to see if they differ at all.

both were set to fat32 and 64k i did a nand dump for the pro time was clocked at 5m.26s will do a test for the evo to compare.

i just googled the price for the sandisk card and it's priced at 58 on amazon? i've only used sandisk once in my life and had a bad exp, with it go for the samsung it's 20$.

i too have a bad exp with sandisk once, it failed after 1 week of usage on my 3dsLL with emunand. I think i will try samsung then.

Do i need to reformat the card to fat32? if so, what cluster size is the best for maximum read and transfer speed?

yes you would need to format the card to fat32 i used minitool for my format size in terms of cluster mine was set to 64k though i've heard for some people it didn't matter what it was set to.

For boot time I'd have to assume the smaller card size played a role.

There's so much wrong or missing from this comparison it's ridiculous.

I've used quite a number of Sandisks of various sizes for various things, and never had a single problem.

what i pointed out was they were both set to fat32 with a cluster size of 64k The pro is promoting a write speed of 80MB/s while the evo is at 20MB/s
pro is marked as UHS-3 which has a base write speed of 30MB/s while the evo is UHS-1 which is 10MB/s
now assuming the n3ds would bottleneck the pros speeds it should in theory be slightly faster then the evo when writing which it wasn't but it did slightly better
in terms of boot time.

I have the pro version of Samsung ,the write speed reach to 60 MBps , 64GB.
Installing cia has little to do with the card,it's from the 3DS it self.

But UHS-3 uses more pins than a standard SD card. So unless the reader uses those extra pins (which most don't) it will be dropped down to UHS-1 speeds.
