I am thinking of getting SanDisk 16GB Mobile Ultra Class 10 UHS-I Micro SD SDHC like that one.
I know I will not reach 10 Class speed but I need to replace my current card and this is the only thing I found from SanDisk.
Can I expect it to perform flawlessly with HTC Desire?

I am using the same card as well, and it works perfectly. With full class 10 speeds as well.
I am using this as well... No problem at all... Getting much faster speed..
Thanks all. The reason I need to change my sd card is because right now I have a Samsung 8GB Class 6 which is fast enough in transfers but slow in initialisation and newer ICS/JB roms can't even detect it.
What rom are you using with this card?
has anybody noticed a performance increase while using a UHS-I card compared to class 10 or class 6.
Desire needs sd with high IO because of the low internal memory. Now the question, which cards have higher IO? Class 6 or 10 or UHS-I?
Im using a 16 gb uhs class 10 and no issues at all

Well, I got my own card and indeed it is working perfectly fine.
Would putting a swap partition on it decrease its lifespan noticeably?
have someone tried the 32gb class 10 version? does it work well with int2ext+ or m2sd?

"Mobile Ultra" is class 6 and "Ultra" is class 10. I don't know if there are any other differences apart from speed.
The link you gave is actually selling an "Ultra", although the title is "Mobile Ultra"
Note, I would never buy an SD card on ebay because of the number of fakes (especially Sandisk apparently)
You can get 16GB "Mobile Ultra" on Amazon for £11.45, ie same price as ebay.
Or a 32GB "Mobile Ultra" on Amazon for £22.99
Or a 32GB "Ultra" on Amazon for £18.54
No, I don't know why the class 10 is cheaper than the class 6. However... "class 6" just means that's the minimum guaranteed speed, it might be faster.
NB from what I've read, most class 10 cards don't work on the HTC Desire at all, but some do* However I've also read that internally the Desire can't read at more than 6mb/s whatever you put in there.
*People seem to have success with ADATA 16mb class 10, but someone else said their SanDisk 10 worked, whereas others say the same card didn't work. YMMV

BUT from what I've read, the HTC Desire will accept a class 10 card, but only has a class 6 transfer bus, so it can't use it any faster anyway.

Not quite right since all sandisk mobile ultra micro sd cards are UHS-1 class cards fastest cards faster than class 10.
They run at double the frequency in a UHS-1 compatible device.
Will still work in the desire just much slower. I get around class 10 speeds from my 8gb .mobile ultra

That's interesting. It would explain why they're more expensive than the class 10 cards. But if you look at this amazon page, it's listed as class 6, which is confusing.
All this talk about speed and class isn't worth much to any a2sd script.
Class system is about sequential speed I.e writing a large file and you'll get the class speed.
Writing loads of small files and I doubt you'll get your class speed.
Plus the apps on your ext4 partition could well be reading and writing from both you fat32 and ext4 partition on your SD card slowing the whole thing down.

I suppose the hope is that the higher the class the higher the random read/writes as well as sequential speeds.
But the random write performance measured on Tom's Hardware isn't encouraging (November 10, 2011 so not very current unfortunately, but maybe shows that a class 4 SanDisk isn't to be sneered at)
I was using SanDisk class 4 sd card with InsertCoin-1.1.4 Rom. After upgrading sd card to Kingston class 10, it's really improved the performance of the same Rom.

I've just bought a SanDisk class 6 'mobile ultra' 32gb card.
Someone's posted a CDM showing a random write speed of 1.222 (!), so I'm looking forward to seeing the effect from swapping from my current 0.01 speed card!

I think I read somewhere that it takes the class 2 only, which is what I have on my current Sandisk 16gb card.
I have been looking at 32gb from Sandisk and they seem to be class 2 only.
However, I saw a Kingston card that says:
Compliant — with the SD Card Association card 2.00 specification (Class 4 & Class 6) and with the SD Card Association card 3.00 specification (Class 10)
Rating Write Speed SD Class
(Mbit/s)
13× 16.0 2
26× 32.0 4
40× 48.0 6
66× 80.0 10
I would assume faster is to prefer, but will it work?
and would this be a better option?
Yes. Sometimes, but you probably won't notice it.
I have an 8gb/class 10 and it works great. I don't know that I can tell the speed difference ... but mentally I feel SUPERIOR!
It should be able to handle any current class.

You're definitely of my kind
However, it seems like the snappier card is mainly an improvement if recording or watching Hi-res videos.
Besides, I'm not confident that the post is a legit chip (though poster probably believes so), alternatively that the specs are incorrect. Kingstons site only states 16gb class 10, not a 32gb class 10.

Another vote here for sandisk, havent actually tried their 32GB, but every other card i've had from them has been faultless.
Most important thing w.r.t. memory cards IMO, is to buy from a reliable source. Ebay is rife with fakes.
Arc can handle up to class 6?
Or i shall order a class 8 or 10.
When i bought arc i had in the case a 16gb sdhc card, but i want a faster one
someone was able to get between 6.00 to 6.79 MB/s on his Class 6 16GB MicroSD, but that was on an X10. you might get similar results on the Arc.

just got a lexar 32gb class 10 card from amazon (solutek) works great , faster than standard card supplied with arc
I guess I'll try the Sandisk, much appreciated guys. Now I just need this phone to be shipped.
I Bought a Sandisk Class 4 32GB and it works fine for me.
The data transfer to the card seems faster when I take it out of the phone.
I was thinking of getting Lexar MicroSDHC 32 GB Class 10 from amazon for my arc so anyone have it already and how is it? cus i didn't see any sandisk microsd have class 10 32Gb.
I've used the original Sandisk MicroSd 8 Gb (Class 2) and a Class 6 variant... When you copy big numbers of mp3 or movies to the phone, it really makes a difference. Example: with a Class 2 it takes about up to 1 or more hours to transfer 1 Gb - a Class 6 does the job in less then 5 minutes...! But if you want to buy a good rated SD because of the HD-camera, then Class 2 should be high enough (according to the experts). Any higher only helps if you transfer data a lot/often (like changing your musiccollection on the Arc).

I went and bought a class 6 sdcard from "lexar". And my benchmarks using "sdcard speed" went up a good bit. But the class 6 card cost about $100, with shipp8ing and all. I heard that there's a lot of cheap quality class 6 cards out there that don't give you a increased read/write speed boost over a class 2. So be careful on what brand sdcard you buy...

That seems very speedy for a phone. Wonder what speed a Class 4 would get.
I don't mind paying a bit more. I usually stick with name brand memory chips (sandisk, lexar, kingston, pny). I prefer Sandisk, but I've only seen class 4 32gb chips so far.

I get 10 write 24 read on my class 4 16gb sandisk with a 1024 patch. 1024 seems to work slightly better for my card than 2048, and definitely better than other options I've tried.

From what I understand I would need the class 10 card if I want to record HD video. If I am not going to record video can I get away with class 4?
Thanks for any help!
You do not need a class 10 to record HD Video, a class 4 does the job perfectly well. I had a 32GB class 4 sandisk and it was fine.
I've heard that for smartphones, Class 10 is even worse than lower classes.
That's because class 10 has fast block reading speeding. The problem is that it comes at a price of slow random access reading. If you want to play high bitrate movies from the SD card, higher class will be better for sure. However for day-to-day usage, lower class might make the phone feel faster.

class 4 is good enough for video recording.
iirc, 1080p video on the note is recorded at a bitrate of around 17mbps or so. convert that from bits to bytes and its something like 2.125mb/s minimum required to record videos at 1080p. so anything higher than a class 2 should be fine for playback and recording (unless you encode at a silly bitrate).
the only time i could see anyone really needing the faster class speed would be if you wanted to take 8mp shots in rapid succession. depending on the colour tone of the image you intend to take, the file size can go up to 3mb. at that point, your photos per second will be limited by the speed of your memory card. ie. class 4 = 1 photo per second, class 6 = 2 photos per second, class 10 = 3 photos per second maximum.
Be careful in stores. Went to best buy last night for SD card. Class 4 cards only in phone section but at class 10 price from camera section. Also shelf had classes mixed up only sorted by gb. So pay attention to what your getting

microSD Class 10
What about if you will move (apps2SD) games like Sentinel (TD game) in the microSD, is it necessary to go for c10?
I'm confused on what to buy, c4 or c10.
Need your help!
For me it is. copying movies from PC to my SD card is just painful on class4.
I see that some good class10 cards can write at 20mb/s (sequential), which is 5 times as fast as my current class4 sandisk (4.1mb/s).
The only thing that is holding me back is the price. Once the price comes down a bit ill definitely grab a c10 kingston 32gb.
What about for games you move to your external sd card? Will performance decrease with a c4? Much better with c10?
What can you say about the Ridata 32gb class 10? Is it any good compared to transcend or kingston or sandisk?

As for brand you should look at the particular model rather than judging by just the brand. For instance the sandisk mobile ultra (class 4) beats many of the other class10 cards

When I switched from a class4 32GB sandisk to a class10 32GB Lexar, I noticed the smartphone working faster and snappier, probably APP2SD in gingerbread and pictures and videos in the gallery has something to do with that change in response.
In my experience with memory cards and professional equipment, not only we shall choose for class ratings, but also for trusted brands, like sandisk, lexar and transcend.
To sum up, class10 is better than class4, and if the diference in price is not very high, totally worth it, but, there is a lot more difference in daily use between a galaxy note and a HTC Desire.
Class 10 is for marketing, it's totally not needed for smartphone with internal memcard.
You might want to read this thread on why class 4 is better suited for smartphone use.

AFAIK Desire supports only Class 6, so your Class 10 SD will work as 6.
You will achieve Class 10 speeds only copying with USB from PC for example.

I doubt you'd get class 10 even through the USB.
Best way to check SD card speeds is to put it in a card reader and into laptop or PC.
Checking through the HTC desire is useless as speeds can vary.
