Upgrading microsd card

I want to upgrade the stock 4 GB microsd in my unrooted htc desire to a 16 GB microsd card. My question is can I copy what is on the 4 GB microsd and transfer them to the new 16 GB microsd and just insert it in? would all programs work?
many thanks for your help.

Yet, the apps are on the phones memory and the info is on the SD card so you can just copy across.

Cheers for the helpful reply.
Are ebay unbranded 16GB microsd cards reliable? Do they work?

i would stay away.

I agree - I had lots of problems with an unbranded 16GB card. Eventually ebay closed the seller down as there were so many complaints. I did get my money back via paypal. I finally bought a branded 32GB card - costly (EUR100!), but I love having so much space for my music / video.

Is there really a need for anything above class 4?
My HTC Desire came with a sandisc 4GB class 2. I want to get a larger card, but never had any reading issues with the class 2, and music and video played off it with ease.
I've seen the following item here, which is for a class 6.
http://www.amazon.co.uk/Transcend-m...r-TS16GUSDHC6/dp/B001PLIG5Y/ref=cm_cr_pr_pb_t
Anyone got one of these?

I've just bought the 'ultra' version of Sandisk's 16GB microsd card and I am very impressed with it so far.
Personally, I always feel that it is best to stick with the tried and trusted brands, and sandisk products have always been excellent for me

I just bought a 16GB SanDisk class 2 from amazon and it writes on average at 5MB ish
-------------------------------------
Sent from my HTC Desire

I thought the class number i.e. 2 meant the read and write speed 2Mbps. Therefore class 6 would be 6Mbps. If you have a class 2 and get 5Mbps then that is pretty impressive.

The Class of the SD card is simply the *minimum* sustained write speed on a card which is completely unfragmented. So, a completely blank Class 2 card should always be able to write large files out at least 2mb/s, but can easily be faster.
My 16gb Sandisk Class 2 reads at 20mb/s and writes at 7.5mb/s - well above the Class 6 minimums.
Regards,
Dave

my 32gb is a class 2 and i have zero issues with streaming video or music from the card, i expect when i root that apps will not be an issue either. plenty of read write speed.
the higher classes are for devices that require a higher bitrate for recording such as mini hd recorders and such.

Im running a SanDisk 16GB Class 6 and its like Lightning!

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.

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

Ive been reading good comments about the sandisk cards, but they only sell class 2 cards :/ , what brands are u guys using?

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

so at £43 pounds i easily get 2x Adata 16 GB class 6
which i already have many (each of my 5 phones has one, plus another one on the video camera CountourHD 1080p), and they work really good
LOL i always run out of battery before i run out of space in my video camera

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.

Which SD card?

Can someone tell me which is the highest class of SD card,which will b fully used by Desire S
And is there noticeable drop in performance of the phone between full 16gb and 32gb?
Thanks

Imo class 10 is the fastest SD-Class.
I'm using a 16Gb class 10 card and it's really fast.
32Gb card was (for me) too expensive...

Class 10 is the fastest micro SD card for now, but the htc engineer does not suggest that we use it because it could lead to some unknown error.
Class6 is enough.
32GB is supported by Desire S.
The purchase of the brand, Samsung is not a good choice because their indicators are virtual.
That's my personal opinion,just for reference.

I moved from a 16g class 4 to a 32g class 6 card, everything runs smoothly and didn't really notice any drop in performance.

i am using Kingston 8GB MicroSDHC Class 4...its working awesome

Toshiba 16gb class 6. No problem so far.

Got a 32 Go samsung class 10, works perfectly for me
tested via SD card tester,
average write speed 9.2 Mo/s
average read speed 11.4 Mo/s
Maybe I was lucky - but I'm happy with it

8 Gb SanDisk Class 4, works well enough but USB transfer speeds could be better

Class 4 sandisk 8gb, 5.8 write, 11 read. Thanks for the other info, I'm upgrading.

Scandisk class 10 16GB works like a charm with no problems.
Read 19.5
Write 8.6

Sandisk 32GB class 10 or Kingston
When you test a lot of roms (as beta tester), different tools or apk skinned, you need some space and faster w /rw
You could find this class of sdcard not really expensive, you must search a little.

i think people are exaggerating with these SD card classess.. my advice is that class4 and a quality brand should be enough for everyone. in fact you can have a class10 card from a noname manufacturer and the actual speed is same as class4 and a good brand. good brands are all that actually manufacture the chips. they are toshiba and sandisk/samsung. if you buy a sony, nokia or similar, you also buy those mentioned before, only rebranded. there is much written about this on the web, but in general: if you can't afford a 16gb class10 sandisk and they are trying to sell you same spec kingston for half of this price, it does mean something!

[Q] Is pulling from micro sd card as fast as internal memory

(1) I'm going to buy a galaxy s4 when it comes out. I know it would probably be cheaper to buy the 16 mg version ,then buy micro sd card.
My question is does the phone work faster from the internal memory or does it pulll info just as fast from a micro sd card?
(2). Would sandisk extreme pro be a good choice ?

i have been using the SanDisk Ultra 32 GB MicroSDHC Class 10 and it works fine in the sg3
just make sure you get the ultra class 10 as it has faster speeds than the lower class cards
put the things that need to pull up fast on the internal memory like apps and put everything else on the card like music and things you wont notice a difference on

Not always true. I recommend reading benchmark test on the card you want to by and its competitors. I've seen some benchmarks where a Class 6 Sandisk beat out a Kingston Class 10 in the past in "some" writing areas.

I had a nightmare with sandisk in general both in my dslr and GS2. I use Lexar now and never had one issue. Sandisk has great customer service though. Refunded all 3 of my pro cards.

If the Galaxy S4 supports the UHS sdcards (45mb or 90mb read/write) then that would be as fast as you need imho.

This is extremely true! Never trust an SD card by what the claims are on the box. I have purchased many SD cards (all brands) over the last couple of months. 6 class 10 Sandisk all 32GB from different sources (Amazon, Best Buy, Radio Shack, etc...) and none of them benchmarked in at class 10. Most were between class 4 and 8 write speeds with read speeds being a bit better. 2 PNY 32 GB class 10 cards. Both of those tested above class 10 performance but died within 2 weeks. I have not been able to find and Amazon Basics 32 GB Class 10, but the other Amazon cards I have tried have worked well. Samsung cards seem to work well as well, but I have not benchmarked any of them. It really seems to be a crapshoot if you get a good card or not. Each specific device seems to like some brands better than others. Also, there is a huge (and I mean huge) problem with counterfeit cards and misrepresented (changed) class of cards flooding all markets. So good luck and let everyone know if you find a good card.

I also would say, download and do a full write format on the card with sdformatter https://www.sdcard.org/downloads/formatter_3/ prior to use. I have gotten many 4 speed cards to record hd video on my t3i just by using that software, when a regular format won't work.
