Mini Review:
All these cards come at the speeds they're advertised at. HOWEVER, and this is very important!: It should be noted that the R/W speeds will differ greatly depending on if you're running exFAT or NTFS.
Benchmarks:
See below for the speeds, though you should keep in mind that your average tablet or phone will most likely throttle the speeds since the voltage output is way lower than on a desk/laptop.
Benchmarks for 128GB 45MB/s, 128GB 80MB/s, 200GB 90MB/s using exFAT:
Benchmarks for 128GB 45MB/s, 128GB 80MB/s, 200GB 90MB/s using NTFS:
I use my trusty Silicon Power USB 3.0 AIO card reader for these tests in case anyone is curious. See attached pictures below for reference when buying say off shady sites or retailers as fakes are easy to come by.
Thanks for the info!
Do you think there is any advantage in getting a microSD card with faster Read/Write speed. such as the Samsung Evo+ or Pro? or is the Read speed limited by the Shield K1's microSD slot?
If you are using marshmallow (6.0) the faster write speeds can be advantageous when using the SD card as internal storage. Apps on the SD card will use the SD card for writing temp files.

Depends on what you're after really. If you only plan on filling it up with Plex/media content, then speed shouldn't be an issue for most once it's there. But if you plan on writing 100GB worth of content back and forth daily, then I would recommend a faster sdcard.
If you plan on using it as internal storage in conjunction with the internal one (feature introduced with 6.0) then I would also recommend a faster card so it matches the eMMC onboard storage speed since it's faster than this sdcard I currently have, not to mention if you plan on gaming (Android and or Shield only games) a lot on this device. For emulathors and stuff this card is enough.
Has anybody some experience with one of those?
-SanDisk Extreme Pro microSDXC (up to 95MB/Sec, Class 10, U3)
-Kingston SDCA3/64GB microSDHC/SDXC (UHS-I U3, 90R/80W)
According to this fairly recent comparison and benchmarks, they are one of the best:

I will hopefully update the thread with the 128GB 80MB/s version as of tomorrow as I managed to snag one for a little over 50€ (Remember, EU here! We have no luxury with 200GB microSD cards being sold for the same price or having 1 gallon of whatever costing the same as 1L of equivalent substance).
edit: no package until monday... sadface.jpg.
poo any decent 64gb cards? was looking at the Samsung evo or SanDisk Ultra 64 GB up to 80 Mbps
@ady702: actually yes.
I made a short benchmark of my 64GB Kingston card (that I mentioned above already):
Results: SD Card - Performance comparison ExFAT vs. NTFS (Benchmark)

so the Kingston would be better than the other two? or is it down to the formatting?
It just means, the Kingston is good.
Though, the thread particularly only tells you that you should format sd cards as NTFS.

Hi all,
I need your opinion. I'm planning to buy a Sandisk 512MB SD Card. How much does it compare with the 256SD Card with regards to speed? Is reading/writing much slower because of its bigger size? BTW my device is XDA. Thanks
My understanding of speed diffs
I don't think 256 vs 512 will make speed differences. The speed differences come between specific cards. My brief research yesterday suggested to me that SanDisk are kinda slow, even the Ultra II cards. It seems the fastest card, consistently, is the Panasonic. I have a plain 256MB sandisk card it PocketMechanic benchmarks it at 0.7x. I will test my new Panasonic card when it arrives later today (hopefully!).
Just for comparison, Lexar 32x cards are rated at 4.8MB/s, the Panasonic is supposedly rated at 10MB/s.
Another data point, I saw a discussion on Amazon.com reviews about the SanDisk 512 and somebody stating it was faster than the 256.
All this leads to: you really need to benchmark the specific cards you are interested in to see if they meet your speed needs. Speed is really variable, people talking about a single process that takes 45 minutes on one card and just like 1 minute on another card (brand).
Got the panasonic card
I got the panasonic card. It writes at "2.9x" as opposed to "0.7x" I got with the stock sandisk. That is better than 4 times the speed. Benchmarked using Pocket Mechanic on an XDA.
Hi,
Can anyone having micro SD 2GB ultra card can tell us about its performance? I have heard that 2Gb card as such had some impact on the performance of the phone and slows it a bit down? Is there any improvement using this faster card?
I have SanDisk 2GB MicroSD - in my opinion it's quicker than my previous 1GB.
I have seen sandisk 2gb ultra II micro sd card in the market. I just wanted to know if it improves the performance over the simple 2gb micro sd card?
i have a SanDisk 2GB standard MicroSD and performance is great, no slow downs on anything.
its a lot faster than a 1Gb card (can't remmeber make, probably SanDisk) that was with my Universal, that was sloooow...
sorry that that doesnt really answer your question, but in my opinion i think that there isn't much gain in opting for the Ultra MicroSD card, as there's not anything wrong with the standard one!
Comparing performance with different flash cards, be sure they are formatted with the same file system (FAT16/FAT32) and the same cluster size. Instead, your comparision results ae meaningless.

I'd suggest you to search for existing threads and articles.
There is no a one-for-all solutions. One thing that I'd recommend is to format with one FAT copy (again, do a search). Then, the bigger the cluster size, the better berformance, but, OTOH, the more space is wasted. With a statistics provided e.g. by SK Tools anybody may make their decision on how to balance. SK Tools also a good tol to format cards with.
As for FAT16 vs FAT32, this is the last thing to decide. If a chosen cluster size allows FAT16 for the card, better to use it. If it does not - you have no a choice but to use FAT32. The only drawback of FAT16 is a fixed root directory size, which is not a big isue with large (16K to 64K) cluster sizes required for FAT16 on big cards.
But the main point for this thread still is: comparing flash card speeds, use the same format parameters.
Had anyone done this kind of comparison on different micro sd cards?
It imaging that this level of testing is about pointless, the typical bottleneck here is likely to be the reader device, not the card.
The phone will likely be the slowest aspect, at least when compared to a desktop reader...

I'm familiar with the difference between the class 4 (4MB/s transfer speed) and the class 6 (6MB/s transfer speed). But is there any value in using a class 6 card on the XV6800 (regardless of size)?
I ask because I have a 4GB class 6 A-Data microSDHC card in my XV6800 right now and there is no problem at all with it. However, I am considering purchasing an 8GB class 4 Sandisk microSDHC card. So it got me thinking, even thought the A-Data card is capable of a faster transfer speed, that doesn't mean the XV6800 is ever actually using that extra speed. So would I see any slowdown if I moved to a "slower" spec'd microsdhc card?
I looked around for transfer speeds on the XV6800's microSD card slot and didn't come across anything.
Anyway have any data on this? Thanks in advance.
Depends some on what you are using it for but I doubt you will notice much of a difference. When transferring using a card and a card reader from your computer you may notice a difference but otherwise the interface in the phone itself doesn't seem to be all that fast anyway.
Don't get me wrong, I appreciate the comment, but that's why I'm asking if anyone has any actual data. The device either reads and writes to the microsd card slot above 4MB/s or it does not. I have not found a way to benchmark it so I'm looking for some actual detail. But thank you.
So I found an application that is supposed to measure the transfer speeds of the card slot on a Windows Mobile device. It's from Audacity Audio. The link on Softpedia is here.
I'm familiar with the application because I used the Palm OS version on my old Treo 700P. The problem is that he results always seem inconsistent and confusing.
In any event, I ran the test on two different microSD cards. The first is an empty 1GB Sandisk microSD card with. These cards don't have a "class" rating. The second is a 4GB AData Class 6 microSDHC card. I still had 2.5GB of the 4GB empty.

Honestly, the scores don't seem to make much sense. The read speeds all indicate north of 4MB/s and most of the time above 6MB/s. That's good. But the write speeds seem pointless. 330KB/s (.3MB/s) for the 1GB and 110KB/s (.1MB/s) for the 4GB ?!?!?! That doesn't seem right.
Anyway, any ideas would be welcome.
Write speeds are typically going to be a great deal slower for flash memory. And larger cards being even slower for writing makes a twisted sort of sense. All flash cards have "load-leveling" algorithms built into them to spread the writes across the flash disk in order to reuse locations as little as possible (flash memory cells have a limited lifetime). So the bigger the card, the more memory the load leveler has to manage. Of course, I could have it completely wrong....
So i'm looking for a new Class 6 8gb SD card to replace my sandisk class 2 8gb sd.
In your opinion, what brand is best to go to, Transcend or Sandisk?
or any other brand, I would like to see options. What brand runs best with apps2sd and linux-swap? I'm currently using enomther's AOSP extpansion pack rom, but i'm thinking about moving to a HTC Hero rom, thus why I need a class 6 sdcard.
Does it really increase the overall speed of a rom?
So, in your honest opinion, which brand should I go to? Links will be appreciated, and I like amazon =D
Sandisk or A-data sd cards are the best.
Class 6 is hellofalot faster then class 2, i only have a class for now since i lost my 8gb.But you should get either one of those maybe transend if its cheaper.
I like my Transcend 8gb Class 6....just wish I could find a 8GB Class 8 or 16GB Class 10.
This is my SD card and it runs lightning fast.

Don't worry phones typically downclock the reader slot to keep battery consumption at a minimum. If you ask anyone to compare a 8gig class 6 vs a 16gig class 6 they will tell you the 8 gig is much faster then the 16. It's because the bigger card needs more voltage to get to the same speed as the 8 gig card due to it's more condensed package. Also this is to allow for less heat issues cause of course more voltage to the card slot means more heat.

so does that mean (in theory) that a 32gb would be super dooper slow? For linux-swap and such?
I'e never had any problems with transcend. I got my 8GB class 6 from Amazon for £14
Hi all,
For android on TP2 (rhodium 400 for my case), would it be worth upgrading to a 4GB SDHC to run the android files?
Would it be noticeably faster?
I see 4GB microSDHC goin for about $8 on Amazon, and I might go for one if it makes any difference in android performance. Anybody's opinions?
Currently I have 2GB (I think class 1).
Thanks in advance.

If it's not an SDHC (or better) card it's technically "classless". At any rate, I doubt seriously that you'd see any better performance on it. I have a 2gb "classless" card and an 8gb class4 card, and honestly Android runs about the same on either card...

most of the 2gb cards are pretty good in speed, name-brand manufacturers didn't have to put a class on it - i get around 19mb/s read, 10mb/s write on my sandisk 2gb.
anything more - 4gb/8gb/16gb/32gb have classes because they had to do some tweaking for the sdhc specifications, with classes meaning minimum sequential write (C2, C4, C6, C10 = minimum 2mb-4mb-6mb-10mb/s sequential write). obviously, there are some cards that could perform faster than their minimum write speed (my sandisk 32gb C2 does 5.5mb/s write, and my a-data 16gb C4 does 9mb/s write)
just don't get a crappy generic
Mine must be classless. I am not exactly sure how fast my 2gb is, but it's at a decent speed. When I transfer about 200 mb files, it takes me about a minute roughly. I will just stick to my 2gb then.
Saves me $8 bucks! Thanks to both.
