Hello xda-users,
I would like to buy a microSD card for my HTC Tattoo,
although i noticed in the market that there are maaaaaaany
microSD cards available without any differences.. (except the capacity)
What i noticed and i was curious about is that when
i tried to bought a microSD from a store here in my neighbour
i looked that a microSD 4GB costs about 15 $ and a microSD 4GB [ULTRA]
costs about 25 $ so i wondered what the difference could it be?
I searched the web [yep, google is my best pal] and i saw that there
were only differences in the data writing/reading speed, and not so
dramatically changes.. just a lil bit. They 've told me that if i wanted
the microSD for my mobile i souldn't get the ULTRA one, but if i wanted
for my camera i should.
So.. what my question is.. If i choose the ULTRA one, will my mobile be "faster" ?
EDIT: i forgot to tell you that i use my mobile mainly as music player
and surfing the web [not for camera usage]
All your opinions are accepted.

Menios
SPEED
I think you shout get the normal one its only necessary if you use it to copy and past many files. i don't think that it give you more speed in your mobile

your english is just fine m8.
Thanks for your advice
I would say - get normal one!
Its 15$ and 25$, difference is almoust twice!
Ok, if u got planty of money, you can take the ultra, I dont know what are actully difference in speed, but mostly u would be using "reading" speed, and when u open ur music player, it reads music files, indexes them etc. It would be slightly faster at reading, but I dont think the difference would be 10$ worth
Post the speeds for boath, if u found them.
Id take ultra if it would be 18$ compared to 15$ normal
P.S. 4GB only? I got 8GB, and Im feeling that I might be to short later I might want to put some movie or something in it
P.P.S. as it would be for camera - you would want all the speed, as when u take pic, u want it to be writen in memory as fast as possible to take another shot, so it might be reason why it would be better for cameras.

Hahaha, thank you for your advice, but as it's the double price, i'll pay 20 $ to take a 16 gb one
Thanks again my friend
20$ to take 16GB ONE? WTF???
I payd... let me count, 18Lats, which is 1Lat=2$, so 36$ for my 8GB one
Ofc I could buy in e-bay, but then I should w8 for a month for it to come... didnt want to wait, so ****s in my country cost alot...
Anyway, no problem

Does your 16GB card work in you Tattoo.
I´ve try two 16GB card and no one of this work in my Tattoo.
They works for a while then I get a message that it´s some error with the card and need to format the card.
The cards works fine in my daugthers Huawei phone so it´s not any wrong with the card exept that it´s not working in my Tattoo
the diference is only in the speed. Usually, these types of cards (ultra) are used in video recorder cams, that need an high rec speed.
So, u should by a normal one
sorry about my bad english
So, which one did u buy? Just wondering...
Today I bought sdhc (what difference sd and sdhc?) 16gb card, and it works fine, But before...
I had 8gb card sdhc and it woks fine until yesterday... Tattoo was running on Froyo, then suddenly hangs on, pulling out battery, starting again... and card is unreadable, my photocam says that it locked(adapter isn't locked), Tattoo don't see it... What the problems with it, does any one know?
Sent from my HTC Tattoo using XDA Premium App
Not sure about the ULTRA label, but when i bought i looked at the class of the micro SD card.
Class 2: minimum sustained Data Transfer Speed of 2MB/sec
Class 4: minimum sustained Data Transfer Speed of 4MB/sec
Class 6: minimum sustained Data Transfer Speed of 6MB/sec
Just clarify:
SD cards can not be bigger than 2GB and are slower compared to SDHC which stands for Secure Digital High Capacity.
Having a large capacity and high transfer speed when using apps2sd seemed like a good idea.
I'm not completely sure, how big is the affect how having faster card, but to be on the safe side I went for Transcend 8 GB Class 6 microSDHC.
£10 from UK ebay.

The company I'm working for gave me an HTC Kaiser as work phone. I had a 2gb microSD card as spare, so Im using it for now. What I'm wondering is the phone's read/write speed.
I am considering to buy a 16gb class 6 microSDHC card, would that be an overkill? (not the size of course, Im going to put a lot music etc, but would class 2 or 4 be enough for it? Also, I liked this phone, but just loved HD2(some use LEO, too. I wonder why HTC uses just too many aliases, anyways). I may buy it, so even a class6 card would be overkill for tytnII, would it be an overkill for hd2, too?
Thanks in advance,

A class 6 is overkill for the Kaiser, but bigger/faster is always better. It is not overkill for the Leo.
Rule of thumb is always buy the biggest/fastest you can afford because you never know what you will be doing with it.
However, remember, if you try to drain a bathtub through a 5 cm hole or you try and drain a lake through a 5 cm hole, the same amount of water will still come out the other side.
May be too high price : )

high price I would buy a x10 or HTC before getting that 32gb card. My x1 was $400 alone and this would be an extra $250 just saying for $650 we could buying something with alittle more power..
I bought another 16GB memory cards with only Rp. 360.000,- or around 35 US$ last week.
So if would like to buy 32GB, how to buy 2 16GB memory cards?
Hi,
I'm thinking about 32GB microSD, too. It's getting cheaper and cheaper day by day on ebay and dhgate...
Can anybody confirm that it works?
I'll order one and try it myself if nobody says that xperia x1 doesn't compatible with it.
lol this is wayyy to much money for me to dabble into!
$18.24 ?
I'll order one from dhgate and will report my experience.
I got one from expansys, working like a charm
Nice to hear that it works. I intend to buy one too but I dont want to waste monney on a card that wont be recognised by my Xperia X1.
Sorry, i just wanted to say that i didn't order it at the end. I wanted it faster, so i bought an 8gb one.
I think I'm going to order one soon since the price has come down a bit. The minute I hold it in my hands I will post my experience.
did 16gb works ok?
Work perfect
no problems in lagging? No hang-ups? I'm using 8gb right now and am afraid of upgrading because I had problems before when I have lots of apps installed and it slowed down my phone. Like reallly slow.
this time i m using 16 gb sandisk microsd card which is work awesome without any problem ya definately xperia support 32 gb card without any problem because xperia Hardware is Much Better than Other device and good Configuration
I had 16 GB in my x1... and despite my best effort i never used more than 5 GB, so i deleted few useless things, inserted back my 4 GB card, and the 16 GB card is now in my PSP, where it's still used by, say, 50% only.
And to stay on topic, yes, it works, i had the pleasure to test it, though i never had one... edit: and regarding lags: it's more like how much files are on the card, not how big they are... you can stock up 512 MB card to lags as simple as you can do so with 32 GB... just you don't use MP3's but text files... to prevent this, create subfolders... example:
\Music\Favorite Singer\Favorite Album\Favorite Song.mp3
this way there is no chance to experience any lags while browsing files...
btw: try to open \windows\ folder, that's how it should not look...

Absolutely right.
I'm using a 16GB one, with around 600 songs (sorted in folders by genre\artist\album), no lagging when browsing card or using phone.
There shouldn't be a reason why a 32gb card won't work.
It works perfectly but if you feel it bit slower just use tnyynt SD TuneUP app which makes the reading realy fast for more energy of course...
I have finally got my hands on a 32 GB card. It's a Sandisk class 4 and it is recognized by the Xperia X1 without any problems at all. And I don't think there is any difference in writing/ reading speed between my old 16 GB Sandisk class 2 and the new one. I'm absolutely satisfied.
NO
I think it‘s impossible，because it can make X1 become slower and slower！

Hi,
I want to buy a micro SD : I have seen that the maximum storage for micro sd was of 16 GB.
Someone has already tested a 32 GB storage card?
If yes, Does it work correctly?
Thanks for your answer.
it's works i don't now how becouse i just test my friends card.
Sorry for my English
Maybe it's was on android 1.6 (max 16), but 2.1 should be supported with 32GB
well, i got my X8 only a week ago, it's my first smartphone.
seriously, what do you guys want to store with 32GB card?
i can't imagine what to store in such space, i figure one could make a portable toilet out of it and still got some more space.
Movies (avi, wmv, etc). HD photos from professional photocameras, hi fi music like wav. Download a lot of stuff with torrent client and else. 32 GB really need for me.

Question was not what I do with all that storage.
Is it possible to have 32GB card in X8 I think that it support up to 16GB ??
I couldn't tell you, because I've bought an 16GB card (class10).
With the price of a 32 GB microSD, I could not fool me.
I think that 32GB is more money then the Phone
You are able to mount 32GB card I've just checked it out but the results are horrible - 500 MB of freshly copied music on the card, and now it is showed as "damaged" on the notification bar. I wouldn't recommend it to you.

I think the X8 will also work extrem slow with a sd card of 16 or 32gb
And with 32Gb class10? The read/write speed is biggest?
I believe that is not a question of card's speed, but more of device's ability to comprehend such a huge space. Just like with enormous hard drives in older computers.
ok.. maybe this out of topic..
what brand of SD card with class 6 or 10??
n where to buy??
im just unable to find it in my country.
in my opinion, 32gb can be handle with very well if this SD card are good.
i mean good SDHC
i found it in my country, designed for camcorder and etc..
but price also different
i just want 8gb with class 10..
currently i have 8gb, no class
my quadrant almost same with droid x, so i think if i have good SD card i can overlap droid x.
where to buy???
32 gb for a phone is a lot of capacity
Im using 32gb sandisk class 2 memory card in my galaxy s initially when it was 2.1 it was slow. But now after 2.2 update its okay. Only startup and shut down process Will take long time. class doesn't matter on phone it matters only when data is to be transferred from pc to phone . Max transfer speed Will be 2mbps in class 2.

there's a lot of good brand to choose actually, personally i'm using transcend.
what city are you in? in Bandung, you can try BEC. i bought mine from kaskus though, it has almost everything we look for
class.. hmm IMO it's unnecessary to use such a high class card. class 6 (6MB/s) is sufficient enough, because android apps are usually not really big, only 10-12 MB at most so no need for such a large data transfer rate.
Has anyone had good success with the 32Gb card? I dont want to buy one if it's just gonna not work properly.
thanks
Won't work
Chances are, it wouldn't work.
The Xperia X8 currently only supports up to 16GB of memory. If you go higher than that you would experience problems. You might be able to make it work for a few minutes then it might not be able to read the mem card.
Hopefully, in future updates we could use 32GB cards.
I've searched around, no walk-arounds on this yet. If I were you, I'd stick with 16GB. That's a lot of storage!
Just got NC for early Father's Day! I luv ma fam!
Everything I been finding here talks about 2,4, or 8 gigs SD cards.
NC says it can use up to 32gig.
Anyone tried this? I figure SDHC 32 G class 6 would work.

Everything I've read states the higher capacity cards don't do well running ROMs. Like you I'm new to the nook so I"m sure someone else with more experience will chime in.
I have a 32 gig card installed right now. Works just fine as a data card.
If you want to run custom ROMS off the card, make sure its a sandisk. That flapping sound about larger sized card being bad for Roms is a buncha crap in my opinion (and I have the benchmarks on this card to prove it), but the BRAND of card makes a huge difference when running Roms. Avoid transcend and PNY like the plague.
That said, if you just want the card for data, then yes, the NC can handle them just fine.

What size Sandisk card do you recommend for running custom ROMs? I've read 8 but I really would like to run a 16.
With a sandisk, I can't see any reason why a 16 or even 32 gig card would give you trouble on roms.
Using the card to run your "operating system" seems to require a higher small-block read/write speed than most cards have. Two things seem to affect it: 1) brand (sandisk is currently the only way to go), and 2)it seems that higher classed cards sacrifice the small block performance a bit. This makes sense to me, since the classification related to large block sequential read/writes (iirc), so some trade-iffs are always expected.
See this thread for useful things.
And I think most people are buying the smaller card mostly because of price, and partly due to a herd mentality on threads like the above.
Sandisk 16gb is just fine for running the Rom off the sd card; that is my current setup.

I was referring to the specific instance of using transcend for running cm7 for example. I understand transcend and patriot are decent when used for data, and I have PNY cards in our cameras, so they seem to work fine for data.
I have a wintec SDCH 16g class 4 and it works fine, but I only use it for data.
I've been looking into this, and here's what it boils down to:
Most MicroSD cards are set up for data transfer aimed at large files, such as video or high resolution pictures. The majority of the market these cards are manufactured for are digital camcorders, cameras, and smart phones with cameras.
They've gotten great at streaming media to and from the cards, and using them as storage mediums.
Running an operating system from the card requires a whole lot of small data transfers, which is not a specification that manufacterers pay much attention to. Most people would never notice improvement in this area of the manufacturing process, so the companies don't waste money on it.
Different manufacturers have different ideas of what their product should be capable of.
SanDisk is the brand that has consistently tested better for small data transfer then other card makers.
Running programs/operating systems from a MicroSD card is a new animal, something that hasn't really been done before now, and the tablet market is still in it's infancy.
I'm sure this issue will be addressed by the hardware makers of memory cards over the next year or so, but for now we are stuck with the task of trying to figure out what works for our purpose given what's available on the market right now.
All this being said, out of a handful of cards I own, my 16 gig SanDisk class 2 MicroSD card is my highest performing card - more then twice as fast as even 4 out of 5 of the 8 gig SanDisk cards I have.
Here is the link to the software we are using to test the cards: Crystal Disk Mark
Post 5 in this thread has a link that takes you to the one that has become our communal benchmark thread, and has a lot of info on this topic.
I would surmise that a 32 gig SanDisk brand card would probably be pretty good given that:
-Sandisk 8 gig cards (in class 2 and 4) are the general recommendation
-SanDisk 16 gig cards consistently test to a higher performance level then the 8 gig cards.
If this is the beginning of a pattern, and the larger capacity SanDisk cards are inherently manufactered to a higher small data standard, then theoretically the 32 gig card would be better.
But, this is only a theory. A 32 gig card is more then just a couple of bucks, and I don't think we have enough benchmarks on them yet to say one way or another.
Even with the SanDisk 8 gig cards, there is a wide range of what you could end up with on small data transfer speed. It's kind of pot luck. Even the slowest ones are many orders of magnitude faster then most other manufacturers, though.
This would be a good thread for people who do have 32 gig cards of any brand to chime in on, so we could keep the discussion about the largest supported capacity card on the Nook seperate from the other threads on this topic.
I saw a thread a week or so ago regarding testing class 4 cards and which were better. I just ordered a NC the other day. Anyone know the thread?

You might mean my thread on comparing speed results between different readers using the benchmark software.
It's more a look at the testing software and methods of doing so then the actual cards themselves.
The more people who post benchmark results in the thread skwalas linked to back in post 5, the better of an idea we'll have of what works for us.
The amount of information we've collected so far in such a short time is astonishing - this is a great community.

Bought this one about a month ago. Transferred my 16G class 2 from Radio Shack to the 32G then expanded the partition. I run CM7 off the SD. Works GREAT!. I run movies, apps from the card with tons of room.

IIRC, Lexar splits their Class X cards into two more classifications, a regular and an Ultra class. Which one was yours?
Also, Radio Shack currently has 8gb Sandisk C4 cards for sale at 14.99. Perfect for playing with an SD install. With Crystal mark and a cheapie USB reader I got 2.5mb/s read, 1.5 mb/s write (both of the small block ones). I believe these are the important ones for an SD card based ROM?
I suspect the main reason there's not much info out there on 32GB cards is that people are less willing to drop $50-80 on something that may not work (IF they're trying to run a custom ROM from the card). If you're not trying to set up a custom ROM install on the SD, get any card you want--you may appreciate that higher sequential read/write in the higher class cards when you're moving multiple GB of movies or music to and from the card.
From everything I've read, the size of the card makes no difference whatsoever. The only reason people harp on the 8GB and 16GB Sandisk cards is because those specific models (both class 2 and 4 in those sizes) have been tested many times and return both reliably high small-block random writes and positive anecdotal reports for running ROMs. The size, manufacturer and class are irrelevant in and of themselves: they just let us identify specific models identified as most consistently working well.
Also, CrystalDiskMark is not malware: just do a custom install and choose not to install whatever is bundled with it (do this always for all software, I'd say). It's whatever program they use to suggest other software that triggers the false positives in security programs.
