IDK why class two was the most expensive, I always run class 6, higher then that are extremely hard to find, and i'm not sure what the expansion port's max speed is, I have heard there is no difference with the one or two higher class 10 cards that are available
SD: Class0: below 2GB
SDHC: Class2(2MB/sec)
SDHC: Class4(4MB/sec)
SDHC: Class6(6MB/sec)
Class2&4 fit a smart-phone the most.
Class6 is kinda too quick for a cell...people often use it in a DSLR(Digital Single Lens Reflex)
The quicker speed of transferring a card has ,the bigger the capacity is.(well......usually.....)
BUT when you use a very very big card in you phone.Let's say 32 GB . Your phone WILL be burdened by the card,thus slowing down significantly.
Hope what I said was right..
8GB is the sweet spot.

Just wondering if anyone knew what brands work better than others. I recently put a Patriot 8GB class 4 in my N1 and it causes massive stability problems under read/write access to the SD card. Usually results in a freeze then reboot. Can anyone reccomend a more suitable brand?? thanks!
I don't think it is as important on the nexus as it was on say a G1 ot MT3G. Unless you are still running a2sd. Obviously the higher the card's class, the faster your transfer will be. I would still stick to the higer class cards. Transcend and Sandisk both make really good class 6 cards.

The 4GB that came with the nexus was a Sandisk Class 2. the class 4 patriot doesnt really seem to make a difference in speed, so I just should have stuck with the original brand
will the 32gb mirco sd class 2 be fast enough to run apps off the sd card without problems?? or should i sacrifice size with speed and get a 16gb class 4 or 6?
yes its plenty for this handset. many many many people already have theses cards in the droid and the evo and all have had much success with it.
Works fine for me.

I use a class 10, to reduce the current draw. If I were to run it a maximum speed it would be limited by the heat it would generate. So in affect it would be limited by the current it consumes. Not talking about leaks, but overall. Slower sd's are also limited the same way but consume their limit at slower speeds. Since the faster cards are limited (maxed) at higher speeds they consume less at slower speeds, because they are rated at uamps/read/write.
Engadget posted about a class 4 just the other day, due to my post count I can't link. But kingston does have one, even though it's much more expensive. If you're running out of room I would suggest only keeping vital media files with you, and using subsonic to stream anything else.
i wanted the extra space so i can use the phone as an ipod since my zune crashed
Class two is damn slow, I did in fact notice a good speed jump with my class 6

Got my 16gb on eBay for around 28! It is probably class 2 but I don't care lol
I bought one of THESE class 6, 16gb microSD cards, and it seems to be pretty good. No problems so far.
I'm using a class 2 to run apps off of and its plenty fast (also cause im to cheap to buy anything better lol)
Yeah class 2 should be totally fine

tkirton recommends at least a class 4 for Dark Tremor. My G1 would crash on anything less than a class 6 when running apps2sd but that phone is a bit inferior to this one. Not sure if Google has a recommendation for Froyo a2sd.

I will be using it for storing/taking photos/movies and storing lots of gameloft HD games on it.
Which is better for my x10 with what I use it for? Which one will have better performance when it comes viewing photos and movies? Will the games load faster on the pny class 10?
Or will the difference in performance from two cards not noticeable from everyday use?
Thanks
Not card wise but company wise, sandisk makes better memory cards if not the best in my opinion. I have never had a problem with their cards.
Choose them if the memory card you need is made by them.

Read speeds can be significantly improved with the SD Speed Increase app developed by a xda member. Write speeds have no such cache fix available.
Unless you are writing very sequencally all cards are very slow. Technically a class 10 should be twice as fast with seq writes, but differences in materials and design sometimes reduce the difference.
A 32gb Kingston class 4 writes at 4.356 MB/s and a Lexar 32gb class 10 writes at 11.44 MB/s. But a Class 4 8gb Sony writes at 10.19MB/s! So what you actually get will be unknown until you have the cards.

Hi there, i just bought a generic 16gb class 10 microSDHC card off of ebay for £16, it was cheap so i was a bit skeptical, but i received it and did sum read write tests, i got upto 11meg write speed so atleast i know its not a fake, but its working well videos and pics are saving a lot quicker so im happy with it for the moment.
I have both cards right now, It was used for my sony camcorder.
How can I test both of them in my phone?
stan.s whats that app you are referring to? where can I find it?
THanks

I bought a PNY 16Gb Class 10 off PLAY for a bargain price (about £16) and am now in the process of returning it as I had to keep fixing errors using my PC.
I have had a lot of PNY flash cards for my camera with no problems, so hop this is just a one-off?
Hopefully the replacement card (a direct replacement) will be better.....

I'm using PNY 16gb class 10 for my x10....
is good.... no prb at all
It varies alot depending on brand but last time I checked android simply didnt take advantage from anything faster than class 4.. You can of course remove card plug it into pc card reader and fill it faster.. But android os is limited and wont take advantage of a class 10 card speed. Maybe on 2.3 or 3.0 ? But it doesnt on 2.1/2.2 at least

How much does the class rating of an SD card make a difference in a phone?
New Egg has a great deal on a 16GB Class 4 card.
I have a class 4 card now, but I've never used a 6 or 10. So I don't know if there's a whole world of performance I'm missing out on.
I run Cyanogen so I do have a considerable amount of APP2SD action going on. But I don't otherwise write to the SD card a considerable amount. Don't take a lot of videos....don't transfer 4 or 5 GB worth of music everyday. Nothing like that.
Visit Wikipedia or Google for the transfer rates and think about how much I/O you will be doing. The more stuff apps and data you store on your card the more important the performace and compare that to what experience you have.
Being used to sticking a stick in a USB 1.1 slot and groaning at old computers, so I tend to divide by 2 when judging such things. E.g. if it's 480m/b, I make the expectation off reality being closer to 240m/b. Can't complain about MicroSD's much since my current handset has a freebie 2GB >_<. I assume it's class 4 but it is fine for me, and most of my stuff is on it.

Take one thing into consideration: class of the SD card means nothing, if the device's own transfer (specifically, write) rate is too slow to utilize it.

Well that's a good point.
I have no idea what the write speed of a MT4G is. But I've had a Class 4 card since I bought the phone and it seems to work nicely. I've never said "Man I can't believe it's taking this long to save this file!"
So I went for the $17 special on New Egg for a 16GB Kingston card.
Search micro SD card 16gb on New Egg. It's the cheapest one. Brand name. Free shipping. Can't go wrong there.
No point in getting a class 10 unless you transfer via this usb adapters.. I think the mytouch stops at like class 8. Not worth it unless on sale. You can live with a couple seconds of wait time

I agree, I wouldn't go any higher than a class 4 or 6 for a phone. I have a ADATA 16gb class 6 and have never had any problems with transfer/read/write speeds

I have a Class 10 card, but only because I transfer files to and from my computer on a semi-regular basis. I used an 8GB microSDHC Class 4 card in my previous phone and one time I found myself needing to transfer a lot of data off of a computer. All I had left on hand was that Class 4 card with its SD adapter and it was horribly slow in my SanDisk MicroMate adapter that I typically use in conjunction with a 4GB SanDisk Extreme III SDHC card as a flash drive.
I agree that you're not going to get much more out of the phone itself beyond Class 6.
I'm wanting to buy a high performance SD card to run my Code Name Bleu Mynt ROM. I want a 32GB card, but I was looking at an Eye Fi 16GB at this link. http://www.eye.fi/products/prox2 Do I need something like this or is it overkill for an Android phone? Mostly I'm looking for speed, so I was thinking any class 10 would be okay. What are your thoughts on the best high performance SD card?
Well the og tops out at class 6. I use sandisk cards. I have a class 10 16gig and class 4 32 gig. I notice no difference between the two on the og and only a small difference on my 3vo. Class 10 won't hurt anything plus when you upgrade your phone you won't have to upgrade your card. Also some users have even been able to use the 64 gig with the og.
Also Kingston is very reliable.
