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.

Class 6?

I'm thinking about buying a 16gb microsd class 6 card. Will the 6 really make a difference from a class 4 on the eris though? Once they get that fast can the eris really keep up or will it just be excess speed for nothing? Also, I'm guessing a 32gb c6 is out of the question? As far as brands go, are there any that I have to avoid. I'm looking to buy a cheap one from one of those ebay sellers in china with the free shipping. Is this a bad idea? Will it not work with the eris? Thanks.

A lot of money for not a ton of improvement. If you use apps2sd it'll matter more but not hugely.

I use a class 4 8gb Kingston with no problems at all, didn't see the point in buying an exspensive class 6. That and a2sd works great on a class 4

This is a cheap yet quick class 6: http://www.newegg.com/Product/Product.aspx?Item=N82E16820208453

Two worthless posts, dude. You didn't explain, you only gave an opinion, but I'm afraid you're wrong and your uninformative posts didn't warrant reviving two dead threads just to get your post count up.
There are most definitely speed differences between different classes of SD cards.
Next time, think before you post.

I've used 3 cards. The SD card that came with the phone (8GB Class ?), a SanDisk 8GB Class 2 card (from Best Buy for ~$40), and an A-Data 8GB Class 6 card (from Frys for ~$25). The Class 6 card is MUCH quicker in day to day use. Launching most apps (on SD card) is noticeably quicker than the system apps stored on the phone for example. Comparing card to card is night and day as well! The original card was similar in speed to the SanDisk one, but the A-Data card seems about 2-3x faster. Viewing images in the gallery is also much quicker with no lag of loading a picture of relatively high quality.
Summary: There is a noticeable difference! A friend has a Class 4 card and it feels slower but seems to be closer to the Class 6 end than it is to Class 2. That isn't to say it's slow/bad, but it isn't as fast, especially in gallery.
(all on Fresh Installs of CELB Froyo 4.3)

Fact is.... it makes a difference depending on what you do. here are my tests after buying a class 10 16GB from amazon:
KingMax 16GB class 10:
Writing speed: 13.8 MByte/s
Reading speed: 16.6 MByte/s
SanDisk 8GB Class 2:
Writing speed: 6.56 MByte/s
Reading speed: 17.4 MByte/s
I used the following program to test directly from the SD card slot on my laptop, not from the eris:
Program on PC: H2testw.
my camera app takes pictures a tad faster, I assume due to the write speed to the SD card. Other than that I dont use the SD card for much else besides storing and looking photos and playing music. I dont use app2sd.

wow this made me go ahead and wanting to buy the A-Data 8GB Class 6 SDcard
so you say ~$25? I just saw on newegg they were selling for $12.99 w/ free shipping
A-DATA Turbo 8GB Secure Digital High-Capacity (SDHC) Flash Card Model TurboSD SDHC 8G
would that be the correct model you have?

I got it at Fry's a couple of months ago so it may have dropped a bit.
And yes, it is.

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.

lexar 32gb class 10? jezus christ you must have payen an arm and a leg for that ****.

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...
http://www.amazon.com/Lexar-MicroSD...610M/ref=sr_1_1?ie=UTF8&qid=1296152464&sr=8-1
Anyway, i got a 16gb class2 card (a-data) and i can play 720p and record just fine...
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.

transcend, SanDisk or Samsung

Ok I am about to replace the stock 8GB Samsung card and my major requirement is to get Class 6 card and 2nd, to get 16GB.
I am between:
1) Samsung (8GB max class 6)
2) SanDisk (16GB Class 6)
3) Transcend (16GB Class 6)
I tend to trust Samsung better but it offers only 8GB. Samsung clearly described read and write transfer speeds.
On the other hand, Transcend & SanDisk websites don't state transfer speed and I don't just trust the Class 6 logo because I benchmarked my Samsung OEM Class 2 card with a Kingston 8GB Class 4 and the Samsung Class 2 was proved to be faster than Kingston. So, I'm not buying Kingston for sure although I have the channel to get them cheaper.
Has anyone compared the 3? At least I compared Samsung with Kingston and I know Kingston isnn't a good choice. I would like to see similar comparisons between the 3 and also trusted places to get them since eBay and Amazon are full of fake cards.

bos bais philei mou?
i would suggest the sandisk, transcend are dellia skada, the samsung is good, but not quite as good as the sandisk

Thnks my firend,
moreover, I notice that nowhere online (in UK) I can find SanDisk 16GB Class 6 micro sdhc.
A few shops give misleading info as they place a class 6 image in the outside category but inside the specs, they either don't mention or some state class 4 so I can't trust any of them.
Now I don't know who not to trust eBay & Amazon or authorized resellers with misleading specs.

try play.com - but sometimes the class isnt what it says, ive paid for class 4 and got class 2

I have a 8GB class 6 transcend and works fine on desire HD

It seems that ony Transcent has 16GB Class 6 micro sd. (Out of the 3 brands)
SanDisk has them only on their website but not available anywhere.
I'll have to decide between Smasung 8GB Cl6 or Transcent 16GB Cl6.

There’s been various tests & reviews online that more or less always show Sandisk coming out on top and most often delivering much more that what the class promises.
I’ve been using an 8 gb Sandisk class 6 for more than a year (first in Desire, then in DHD) – And switched to a 32 gb Sandisk class 2 a few months ago – No discernable difference in my opinion – Of course benchmarks will tell you otherwise, but they’re … benchmarks.

About sandisk delivering much more of what the class promises, i can't agree more with you.. True though, i've bought sandisk class 2, but the performance is more than my class 4 pendrive sd card.. pendrive brand sucks hard.. i'll never buy other except sandisk..

It's not SanDisk but generic no-name. I wonder if it will really satisfy the class 10 requirements in a micro card since there is no other sinilar from the known brands.

I'd say go for Sandisk. I have a class 4 SDHC microSD. I know it's only 4gb, but it's superior to any other card i've seen. It has write speeds of 20-25 mb/s, and read speads of 50+! Lol it outperforms my dad's class 10 16gb :S I thought that all class 4 cards have similar speeds, so I bought a Samsung 16gb class 4...it writes at 3mb/s
I don't know if this card is unique or if other Sandisk cards are just as fast, but my experiance with Sandisk is quite good

I agree about SanDisk, i have a class 2 8GB and write speed is 7MB/s
The Samsung class 2 8GB that came with my DHD has write speed of about 3MB/s.

I advice against samsung, on my DHD it was in bundle and now it is died after only a life month

Good Sandisk class 2 is sometimes better than other class 6...

i use a Kingston 32gb class 4 card and it works like a charm. Never had problems with Kingston cards.

Lexar class 10 32GB and Patriot class 10 32GB already in the market.
You can find Lexar at amazon and patriot at newegg.

Finally, although I am convinced about SanDisk, I chose Samsung Samsung Plus8GB class 6. The main reason is that it is much cheaper and I saw some performace benchmarks from another member here some time ago which were very impressive and also I could not find a trustworthy place from Internet to buy Sandisk which has been one of the major targets of replicas. Their support also hasn't convinced me because they never replied to some pre-sales questions I sent them. I don't doubt about the superior quality they have though.
We'll see.

Do you get fast read and writes with just a class 6, no lags or slowdown?

[Q] MicroSD Card

Been looking around for which microsd card to replace my venue pro one with. definitely want a 32gb one. Pulled up a few, are a lot of people having problems with the class 4 cards? Should I stick with a class 2, even though the 4 is about the same price, or cheaper? Here are the few I found, all around $80. Price doesn't matter, just want the one that will work the best.

I'm 100% sure someone had posted the 32GB MicroSD card S/N they use. I don't remember which post it was, it is somewhere in the Venue Pro General form.

I think class 6 should work. Max Miller at ZDNet has posted a blog about how he swapped a troublesome dvp's 8gb card with 32gb n the dvp is working like a charm after that. It has a video aswell.

Whats the largest SD card Windows mobile 7 can handle, and if it's less than 128 will it be able to recognize "partitioned" SD cards?

I use a sandisk 32g class 2 and it works fine. Did find a lot of class 4 of same price but skipped as I only saw that class 2 works from posts online.
And from a random (not sure if reliable though) article online, it says WP7's file system depends on random I/O seek time (or alike) which is a different dimension from class, which gauge the continuous transfer speed.

Why would a slower class work better than a faster class of SD? Class ten is the fastest your able to buy.
If I can buy a class 10 32gb would it work?

I swapped my 8GB class 4 that came with the device to a 32 GB SanDisk class 4. I do notice slower write speeds - 720p video in particular seems to have a lag when capturing. Other than that, the phone is zippy fast.

I bought a Dell Venue Pro (normally hate Dell and don't give them the time of day) and from what i've been reading i'm going to be stuck with a class 2 or 4 (32gb) MicroSD card. And to narrow it down even further supposedly the ones that work best with these phones are sandisk.
So my questions are this. Will I actually be able to use a class 10 microsd card or is it a limitation of the physical phone. I mean windows is capable of 32gb and probably more.
If it isn't able to use class 10 right now will there be a firmware update for the phone that will allow it.
What would happen if i bought a kingston or patriot over sandisk (as i've always considered them the bottom of the pile)

I've been using a 32gb sandisk (class 2) for a couple days now and it's awesome. Despite being class 2, it's way faster than the crappy class 4 that came with the phone.
Random r/w speed is the most important thing to worry about with WP7 devices. Class rating does not say anything at all about random r/w speed, just about the maximum throughput. In fact, there is often a NEGATIVE correlation between class rating and random r/w speed - the higher the class, the lower random r/w.
So that's why class 2, 4, or 6 cards seem to be the best.

so could anyone give me a link of the best 32 gb sd card I can use for my DVP that would be awesome.
the one that came with my phone is starting to fail (constantly getting the black screen with memory card problem and asking me to change cards and reset)

another question
let's say something happens with my phone and I need to send it back for warranty repair, could I possibly switch out the sd card back to the original one, reset and be ok?

So does this phone have a SD card that is expandable? I just got the phone a week ago and thought it was built in and couldn't be changed.
