MicroSD for Froyo - general consensus?

Hello,
Now that Froyo more or less came out and apps will start having Apps2SD function, it's time for a MicroSD upgrade.
What I want is on-phone performance - that running heavy 3D games on SD would perform as smoothly as if it was on internal memory. Is there a general consensus on what brand/class would suffice, and what is overkill? I have no concern over data cable transfer speed, as I'm pretty sure the phone will limit the speed much before the SD card does.
I'm looking at this Sandisk 16gb MicroSDHC Class 2 for $35 after shipping:
http://www.amazon.com/SanDisk-Flash...ref=sr_1_1?ie=UTF8&s=pc&qid=1275145563&sr=1-1
Anyone know if this would suffice?
Past threads have always went on tangents about good brand vs knock offs, how class is important vs. a marketing ploy, etc etc. Has a general consensus been reached in the xda community over what is sufficient but not overkill for onboard performance? Perhaps people who have already ran App2SD and use games and videos a lot have some input.
Thanks

I have a Top Ram 16 Gig class 6 and I think I paid about the same as you looking to pay for a class2. I also have a class2 that I have had for over a year. I used to use it in my blackberry. It still works and it is made by one of the cheap manufacturers.

Argh, I'm suffering from chronic SD corruption. So I'm in the market for a new chip. Think I'll spring for a 32gb this time. What's the latest on one that's both compatible and fast? And cheap too, that would be nice, links appreciated.

Considering that due to the amount of RAM the N1 has your main apps will be loaded already so card speed is not a significant factor, unless you use lots of different apps on a regular basis.
A faster card is beneficial mostly for the time i takes when I am loading up new music and possibly vids if you use it for that

This is the first 32gb MicroSD card I have seen "In Stock" Pretty expensive for a class 2 though.

Im not sure the nexus 1 can handle a 32GB card , wow that's a lot lol, but you can get one for like $30 on ebay... http://bit.ly/9J7u2S

You can get a 16gb class 10 for about $90.00.

Micro SDHC is a standard that supports up to 32gb. Of course it can handle it just fine.
I run a 16gb Class 6 in mine, works fine

bewar ebay, there a lot of folks selling fake cards. They even read as what they were sold as but then fill up mighty quick............
The class is not needed I don't think
I have a class six and have been running games on it from sd for 3 months cant tell a bit of difference. I run linpack from sd and it works fine too!

the only real 32gb card is found here., http://www.sandisk.com/products/mobile-memory-products/sandisk-microsdhc

I'm running a 32gb Sandisk Class 2 in my Nexus as of last Friday. No problems (apart from a looooong time to refresh the media library after resyncing my music).

You can not get a genuine 32GB Micro SD card for US$40.
A good class 2 card (2MB/s) will offer you the same performance as any other class in your phone.
The limitation is not the speed of the card.
Buy a brand name card with the capacity you require and be done with the complexity.

I don't know too much about transfer rates but basically what you're saying is that a a brand name class 2 card will be just as good as say a class 6? I'm in the market for a new SD card as well, and the class 6 cards are much more expensive. I'm wondering if they're worth it.

No, in a phone they're not worth it at all and people who say so are either selling snake oil or are embarrassed because they've paid for one and are foolish for doing so.
The best I can do just at the moment is this:
wikipedia said:
In applications that require sustained write throughput, such as video recording, the device may not perform satisfactorily if the SD card's class rating falls below a particular speed. For example, a camcorder that is designed to record to class 6 media may suffer dropouts or corrupted video on slower media.

The Nexus, like probably every other phone out there, is a) not typically used for high rate sustained write activities and b) is designed to write to class 2 media to begin with.
If you have a large, highly fragmented sd card higher speeds will help. This of course is easy to avoid in the first place.
Get a higher capacity, class 2, brand name card for the same money and you're away laughing.
NB - If somebody waves a magic wand and all of a sudden the Nexus can record video at 1080p at a high enough bitrate then perhaps my advice would be invalidated... but don't hold your breath for that to happen...

Thanks for the info man! I was obviously misinformed, you just saved me a bunch of money

so just curious. now that CM 5.0.8 comes with 720p recording, would a class 2 still suffice?

I am also searching the web recently to look for a cost-effective high vol microSD. My finding is: don't 100% trust the "class" specified by mfr. I used ATTO Disk Benchmark to test two 8G microSD that I have: Transcend 8G Class 6 and Sandisk 8G Class 4.
<Transcend Class6> Write: 6-10MB/s Read: 16MB/s
<Sandisk Class 4> Write: 14MB/s Read: 20MB/s
From similar test results on the web, it seems that Sandisk uses to under-state the performance of their card. Finally I get a Sandisk 16G Class 2 for my N1, and here is the test result with the same setting:
<Sandisk 16G Class2> Write: 7MB/s Read: 20MB/s
Although Sandisk only specifies it as class 2, it actually performs like a class 6.
I suspect the importance of the speed of the SD card too, coz I think the write speed into ROM, should be way slower than 6-7MB/s (correct me if I am wrong ^_^)... If the speed of v2.1 w/o app2sd is acceptable to you, then v2.2 with 6-7M write speed card should be logically fine with you.

huh that's interesting. i just might pick that up from amazon then..

I Dont think fragmentation makes any difference to write speed, these are not mechanical devices like hard disks.
Also defragging is pointless and shortens the life of the card by increasing the number of writes.

Is a microsd class 2 enough for recording hd videos and running apps?

Im planning on buying a 16 gb microsd card but all i can find is cards class 2 is that enough for recording 720p and loading applications installed to the SD card ? keep in mind that i also plan un buying a optimus 2x which has 1080p recording
Which brand do you like better? sandisk? kigston? trascend?
I read that sandisk class 4 cards are REALLY good but they dont show up in their website or amazon :/ , it seems they only sell class 2 cards, and kingston offers cards class 10 and 4 , class 10 seems a little excessive

Class 4 but really class 6 is what u need class 2 will die
Sent from my GT-I9000 using XDA App

yeah minimum a class 4
class 2 is just a pain, it will make you want to throw the phone away, and explode it into a million tiny bits
class 6 is the normal speed for a fluid experience

Im using a Sandisk 32GB class 2 card, it writes at 5~7Mb/s depending if its a large file or several smaller ones and read as higher than 15Mb/s

If you are getting a 16gb card, or less sandisk, kingston or toshiba, class 2 or class 4 offers similar read/write speed, although the toshiba and kingston is a little faster, the sandisk is much stable.
Read is about 11-14mb
write is about 8mb
I had a toshiba 16gb class 2 in my i9000, it plays 720p videos without any problems, now i am using a lexar 32gb class 10, results aren't any different.
Hope this helps.

Approximate usd 85.

The class designation of SD Cards ONLY represents the sustained WRITE speed to the card in MB/s. So, class 2 means it can be written to at 2MB/s, while class 10 means it can be written to at 10MB/s.
The designation has no reference whatsoever to the read speed of the card. So, basically every response stating otherwise in this thread is wrong. You should be able to get suitable sustained read speeds out of any class 2 or higher SD Card for the purposes you will be using it for. It will just take you longer to transfer the data to it in the first place. As for video recording from your phone, class should should be plenty as I'm pretty sure 720P comes in under 2MB/s.

Wow, yea. Just that i seen some online shops which class 2 32gb cost 100$
But on amazon the lexar class10 32gb is really cheap...

Electroz is right. Its only about transferring and stuff.

The speed of the card used in the phone does not make much of a difference, its onlt when you transfer data to and from Pc, but its always best to get the fastest available, if the budget is the main problem, consider getting a kingston or toshiba, but make sure you get one that is made in japan, as the taiwan version is a litttle slower, japan version are becoming harder to get now, since the japan factor has transferred their production to the taiwan site.
The classes stated on each card is only the minimum it will reach.
Class 2 at least 2 mb read/write
class 4 at least 4 mb read/write. etc.
So it can be anything above the actual figures.
For more info on microsd, see my link in the sig, although its a little out dated.

The actual retail price for the lexar 32gb class 10 is 149 usd.

No problems with 32GB Class 2 here, it can record and decode 720p just fine, and there is nothing else as intensive as those tasks that you'll be doing with this handset (may not be enough to support 1080p in future handsets, but that remains to be seen).
Don't buy into this rubbish about needing Class 4 or 6 cards, unless you regularly load very large numbers of small files to your card, in which case you may want the higher write speeds.

when you run apps and/or games off the SD (App2SD) the slower the card the more time it takes to have a fluid experience, specially heavy stuff from gamesoft, or simply opening the application manager and waiting for the icons to load
repeat the same tasks with a slower card vs a faster card and you'll see the difference
of course you'll not really see much of a difference, unless you card is more than 50% full, and have over 300+ apps installed

You can buy a Kingmax 16GB Class 6 at Amazon for £43. I didn't had any problem to find it. Class 6 is much better. See you - Frank

If your getting cards from a non generic name brand, the read speeds should be around 15-25Mb/s , My class 6 card actually had a slower read speed of 15Mb/s compared to my Class2 ( 28Mb/s )
At the end of the day the difference between loading something was barely noticeable even skipping to different portions of a 3.7GB movie, Im guessing the phone it self is the bottleneck and not the card.
1% or 99% full should have ZERO effect on the read/write speed this is not some mechanical drive nor having 1 or all the apps in the market.
EDIT:
Again the class rating is only a rate on what is the minimum write speed the card can handle, sandisk rates their 32GB at class 2 when it writes at 6-7Mb/s ( making it class 6 ) on the phone and about 10Mb/s using a card reader ( making it class 10 )

yeh, buying from a local store is cheaper, from the same price of a kingston 16gb class 10, you can get a 32gb class 4, but the fastest microsd on the market is the kingston 32gb class 10, but stock is very limited due to high prices, and you probable need to place an order and pay in advanced, i'm still searching for one, since the last time i heard about it about 9 months ago.
adata are the cheapest cards now, but the speed are rather slow, compared when they only released the 8gb about a year ago.

What memory card do you recommend me?

I'm from the perspective of purchasing a memory card, 16 or 32 GB
I await your advice to not buy anything.
thank you

Just for the record, I'm more tempted by a 32 GB...

depends what you are going to be using it for?
music apps photos etc?
i have a 16Gb class 10 Joytech card in mine and it performs very well

Well, regardless of what you're going to use it for, extra free space is always welcome, and who knows, maybe you'll find yourself in need for more space than a 8 gb or 16, so, if the price difference ain't that big, go for 32.

The biggest and fastest you can get . Recently I bought 16GB class 10, because a/ I wanted to see if a faster card would make the shutter in video recording go away and b/ I needed a bigger card (one that would be enough to store a full season of TV shows - roughly 8GB and have space for my photos/music/apps). Because for me faster was more important than bigger I searched for class 10 cards and settled for 16GB (at a bargain price too - 30 EUR). I have to say that I'm very happy with it - it's really class 10, no shutter at all and I have enough space to copy a full season of a TV show to have with me to watch while I have nothing else to do.

whatever size you do get make sure its minimum class 6 or above otherwise as stated the speed (or lack of) may start to annoy you

SanDisk 16GB, best price-performance ratio!!!!!!!!!!!!!!

Go for 32 Gigs.
even tho if youre low on money go for it! then you`l never go out of space
and the DHD dont slow down either so its a win win win!

Would recomend you to get atleast a 8gb class 6, you can get them for under 9GBP on amazon. In my opinion those are the bare minimums. You need class 6 to record 720p video without stutter and 8 gb holds decent ammount of music/videos.
It all depends on how much you willing to spend in reality.
Personally i just bought Patriot 16GB class 10.

I don't think anything above class 6 is very useful seeing as the memory card reader on the DHD may not be fast enough to read/write anything faster than that, but I could be wrong. I have a 16GB Class 4 Duracell myself which works at very high speeds, way above the classification. For it's price a very good card, in my opinion. But I'd go for 32GB if I had the money for it.

The DHD can read/write at speeds way higher than 6MB/s. My class 10 card has transfers of 19/11 MB/s (in the phone, not via a SD adapter) and there are reports of beter (and more expensive) class 10 cards working at even higher speeds.

I read that some cards were more accurate with their transfer claims than others. Can't remember the brand of card but one was recommended as being closer to the spec than the others. Also remember reading something somewhere that suggested a Class 10 card wasn't desirable and not necessarily faster because of how it worked, and that a Class 6 would do better for read/write and battery life. Your thoughts?

not really sure if I would spend the extra cash on a class 10 16b over a slower card for use in a phone. class 10 are superior for video, especially hd, like with a digital camera.
now, if the price is not much more I would go for class 10 but that is because I have found that once you replace your device, you may use your old card in a new device that now needs a faster card.
from sd association:
Class 2 : H.264 video recording, MPEG-4, MPEG-2 video recording
Class 4: MEPG-2 (HDTV) video recording, DSC consecutive shooting
Class 6: Mega-pixel DSC consecutive shooting, professional video camera
Class 10: Full HD video recording, HD still consecutive shooting
I do not agree with all of those uses but class 6 should be fine for your phone, even class 4 may be. plenty of info on the web if you want to check it out more. Again, if price is not an issue or the price difference is minimal go for a faster card. also, do not buy from ebay as there are a ton of fake cards on the site.

this was a good deal. just expired, but a similar one may surface :0

The problem with these ratings is that they're intended for use in recording devices, and don't discuss suitability for use in a device such as a PDA where you'll be running programs off of the card.
The information I've seen on the 'net is sketchy, which is why I'm asking here.
Two things to answer:
1) What class is suitable for running programs from the card?
2) What brand/model of card comes closest to advertised rating?

It really depends on a number of things, how much information is being used at one time for a certain app, since all apps are different. So you can't really say, but if you want to make sure then go with a class 10. A class 6 should be fine for most of the apps on android though.
As for which brand of card comes closest to advertised. Each Sd card is different just like every processor is different. You can get a Kingston 8gig class 4 that only transfers at 3mb/s or one that transfers at 4.2 mb/s. Generally a good standard to go by is (cheap/fast/reliable) you can only pick two.
The only way you are going to know the actual speed of the card is to bench test it. For my money though I would probably go with kingston or pny.

The stock card is a Sandisk class 4 and based on that I would say that a class 4 would be fine, but a higher class shouldn't hurt.
capman231

My stock card is a samsung class 2..... And it is forever unexpectedly unmounting.......

Just ordered a Kingston 16gig class 4 for $30 shipped on amazon.

i just bought a 2GB PNY from BestBuy for $7. Couldn't be happier!

It really depends on what you plan on doing with the card/phone. If you are just going to use it for apps and smaller data files the class 4 or 6 will be fine. For me I use the phone for work and media. I stream music via bluetooth in my car and wired to my boat while also storing larger pdfs for work, like my companies catalog. Not to mention if I ever want to take any 720p vids.
I have a 16gb class 6 that has outlived its usefulness as Android stores more data on it than my previous windows phone, so I'm deleting more & more music to make room. I just purchased a Wintec 32gb class 10. I will test the speed with the card in the phone mounted to my computer via usb and if the speeds aren't there I have no problem putting it in a card reader to transfer what I need. I can easily throw 18gb of 192bit mp3s on it, more if I keep some of the songs as flac. I feel the time saved transferring justifies the $76 price.
If you go with a larger card just remember to unmount it before disconnecting and you'll save yourself a lot of headaches.

I want a 16 gb card, but which model is the fastest ? i know a class 4 can outperform a class 6 card and so on , a class 4 pny card? a class 4 kingston? or a class 6 trascend?

You have it backwards a class six is supposed to out perform a class four and a class ten is supposed to out perform a class six.

apparently the brands lie when they say what type of cards they're selling, think of it like a 5 mp camera outperforming an 8 mp camera i CAN happen

I'm not saying it can't, I have a 8 mega pixel sony cybershot that has a carl ziess lens and its pictures are way clearer then my 14 mega pixel cannon point and shoot, but like I said before you have to bench test it before you know its true potential. One kingston 16gig class 10 is not going to preform the same as another kingston 16gig class 10. It is possible to have a class 6 out perform a class 10, but in general the higher the class the faster the transfer rates.

Personally I am not sure I tend to stick with pny and kingston. What I would recommend is looking on amazon or another place that has reviews usually a good reviewer will post a bench test with transfer rates.

I have been using this Adata 16gb cl6 for over a year and a half. The only problems I've had with it are occasional corrupting, but that is completely attributable to my lack of unmounting the card before disconnect. I haven't had a single issue since I started unmounting.
I would also recommend their cl10 card which can be found here.
I wish Adata made a 32gb version. I will report my results on the Wintec once I receive it.

I used a class 4 16gb SanDisk for a long time and it always was fine. I am a sucker for room though, and bought a Lexar 32GB Class 10 and I really couldnt be happier.

I just researched this the other day and can't find the link for the life of me..
Basically from what I read the class 2 and class 4 cards have a faster read than the class 6 and 10's. It has to do with some initializing the 6 and 10's do which is an extra step compared to the 2 and 4's.
For a digital camera the class 6's and 10's are better but for phones a class 4 is ideal. If I can find that darn link i'll post it.
I have an 8gb class 6 transend in my N1 atm and when I get my Inspire in tomorrow i'm going to test the class 4 against the class 6 to see which one has a higher read speed.

What class 32gb micro sd?

I know class 10 is faster then class 4 or 6, but just wondering if the Sensation takes advantage of a faster card? For example, will recording in 1080p (on the sensation) be better if i get a class 10, versus a class 4 or 6?
thanks

I would like to know people's opinion or facts on this as well. I'm currently looking for a 32GB card to purchase and this information would really help out.

thats why im trying to figure it out. there is a hugh price difference between a class 4 and class 10 32gb.... Im just trying to figure out if our phone actually uses the extra speed of a class 6 or 10... Also, if recording video on 1080p will be better if i go for a class 6 or 10 over a class 4 (which I think came with the phone)..?

I can say confidently that our phones will perform better using a class 6 over a class 4, but the question of "will our phone use all the speed a class 10 offers?", I can't answer as confident. But I would think that it should not have a problem using a class 10 to its full potential. What class 10 micro are you looking at?
Using Samsung as an example:
http://www.samsung.com/us/computer/memory-storage/MB-MPAGA/US
This is a $55 microSD (it was half off last week on Amazon[Cyber Week]), but the read/write is 24MB/21MB and a class 4 only gets 15MB/7MB(http://www.samsung.com/us/computer/memory-storage/MB-SS4GA/US [this is a SD but of a class 4]).
If anything I would get the class 10 just to be future-proof and avoid having multiple microSD's around the house. I'm using Samsung as a reference and I do not have experience with their memory cards so I am not trying to sell Samsung. I did buy a 16GB class 10 microSD from Sammy via Amazon for Cyber Week (only $30), its being shipped right now, if you want an update I will make another post (class 4 v. class10).

thanks. appreciate the info.
on amazon there is a Samsung class 10 16gb for $20 right now. 16gb would be fine right now, but I dont want to be running out of room in 6 months as I like to record video which takes up a ton of room. so thats why im looking for a 32gb (even though i think that will be way more then i actually need).
on amazon i actually dont see any class 6 32gb cards; except for 1 knockoff brand. so it seems like most 32gb cards are either class 2, 4, or 10. i want to go above a class 4, but class 10 are expensive...
thanks

A-Data Class 10 microSD 32GB
bought that one couple of months ago, verry happy with it. was the cheapes one to get back then, about 55€ / 75$
getting 10,5MB/s writing and about 12MB/s reading on USB port. just a little slower than my flash stick...
didnt notice any change while recording videos, but i dont unse the camera that often.

If you are in the U.S. Fry's has the 32GB Class 10 for $20 off
http://www.frys.com/product/6786695?psrid=14599570
That probably expensive also, but I could not find a 32GB Class 6 either.

I'm using a class 10 16gb card in my sensation
seems fine, only thing that is fast is displaying pics in gallery
wish I got a class 6 and saved the money, I haven't tried 1080p video....
just tried a 10sec video. Wrote instantly on card and playback instantly too
10sec vid is 13.96mb
so I think a class 6 card can write at 6mb/s where as class 10 writes at 10mb/s
class 6 is fine!

I was in the same position as you are right now.
I did a little bit of reading and decided to buy a good (SanDisk) Class 4 over a cheap (alot of offers from brands I never heard of) Class 10/6.
My reasons:
1. Good card with lower speed = less chance of corruption
2. The read-speeds are ~ identical, since I don´t really use 1080p I don´t need high write-speeds (allthough 1080p records without a problem)
3. Random acces speed on lower class cards is higher, since the high write speed is a trade off between random access speed and write speed.
After reading about all that the decision was easy

now im really confused...
a good compromise would be a class 6, but obviously i cant find any brand name class 6 32gb.
I dont really know much about random access speed vs write speed....can you enlighten me? are you saying that class 4 is faster in some situations then a class 10?

The random access speed is splitted in write and read. It is the speed whith which a random bit can be written/read.
It is the value that determines the performance of an app using SD-Card for data.
So in daily use, there shouldn´t be much difference between class4/6/10. If you want to use your SD for daily putting tons of different stuff on it, you may be better of with a class 10. If you put a lot of Music on it and leave it there, a class 4 is the way to go.
(Anyone correct me, if I´m wrong here, but that is what my research brought up)

I'm the same as Sibbi and am using a good quality (SanDisk, same again) class 4 32GB uSD card.
And I have no problems with it at all, it keeps up with video recording (at full HD) and plays back perfectly.
I suppose the additional speed of a class 10 might make the difference if you were copying GBs of data across the USB cable when loading up the card with music or something (in which case just be patient!) but for normal use I really don't have any issues.
The sensation is a good quality expensive device, so my advice would be to use good quality memory in it for reliability, rather than take the risk lowering the reliability of the handset with lower quality accessories.
