[SD Memory Card] - What is the difference?

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?

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.

kaiser microSD card read/write speed

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.

Micro SD Card Help!

Hey looking at getting a new micro SD card for my phone...
Has anyone had experience with these..
http://cgi.ebay.com/New-32GB-TF-Memory-Card-32G-Micro-SD-SDHC-MicroSDHC-TF-/200512447087?pt=Digital_Camera_Memory_Cards&hash=item2eaf79226f#ht_1812wt_1137
They're really cheap... Are there any issues or incompatibilities?
Also does the Class matter much? Like is it worth looking for a class 6 or is the difference on a Smart Phone not worth the extra money.

The class is up to you, its not a huge deal to me, but some people a class 6 is essential.
However, be careful with ebay memory cards of any kind, be sure to do a test of the size as SOON as you get it. people Often will take a 2gb card and have it fake a 32gb memory card. So make sure you test it to make sure. I cant remember the testing program but im sure someone else will list it here.

The class is just write speed isn't it? So what do you notice that in? Recording 720p or something ?? :/ It doesn't seem like it would be that essential for a smart phone

32G for $18 = Fake. Buy it if you want, but it'll be fake.

yeah, basically the class is the read/write speed, somepeople have seen some uninspiring results when comparing a class6 to a class2. It more has to do with data transferring.

What SD card do you recommend?

I am still using the stock 2 gb card that came with my Incredible. I'm looking to get a bigger SD card preferably an 8 or a 16 gb card. What class, size, brand, etc do you guys recommend? Thanks in advance..

They're all pretty much the same. Never heard of a 'bad SD card' company.
I don't think our phones can take advantages of anything above a class 4, so it'd be a waste of money really to spend it on a higher class aka faster card.
This would be my first choice:
http://www.amazon.com/SanDisk-micro...H0SC/ref=sr_1_2?ie=UTF8&qid=1316312237&sr=8-2
It's actually the card I've been using for a year. Works great, quick and still a lot of room left on it.

I'm not sure I ever actually understood the whole speed thing. Is it how fast stuff is read off the card by our phone, or how fast things transfer from my computer into the card?
Sent from my ADR6300 using XDA App

speed ratings are how fast data is WRITTEN to the card.

The Incredible only came with a 2GB card? I'm still using the 8GB card that came with my Eris. Unfortunately nandroid backups take up so much room on this phone, I usually can only store 1. I'm not sure I want to invest in one since most phones seem to be coming with 16GB ones now.

Yeah.
I guess to break it down a little more, our phone only uses
- MicroSD
- Class 4 (classes are just speed ratings for the card and I do not believe our phone supports higher than 4 - not to mention there's nothing practical that you would need to go that quick on a phone anyway)
- Up to 32 (HTC says 32) // Verizon says 16.
I don't know of anyone who has used a 32, again I don't think it's very practical unless maybe you have your entire music library of 20,000 songs on your phone.

I have tried 3 different cards, PNY, Kingston, and San-disk. I have had issues with, PNY and Kingston, but never with any issues with San-disk.

I'm using a 32 GB SanDisk with no problems. I just didn't want to go through the hassle of buying a 16 GB only to replace it with a 32 GB later. I'm only using 12 GB and most of that is nandroid backups that I could probably get rid of.
The sweet spot price wise is probably the $15 16 GB instead of the $60+ 32 GB. But if you want/need 32 GB, it does work.

i have a 32gig scan disk and have had no problems with it.

Be careful when purchasing SD cards on eBay or 3rd party retailers on Amazon because there are a TON of counterfeit cards out there.

I figured my best bet was to buy one directly from Amazon if I bought it online.

You're right on that. Basically, if the deal looks to good to be true, then it probably is.

I'm using an el-cheapo 16GB Class 2 SanDisk card. Hasn't given me any issues yet, and its been through 3 different phones now.

I would get the largest size card you can afford...then you can keep as many apps on it, music, pics, etc on it, and save the internal space for cache and not have the phone go crazy if you forget to clear it in awhile.

I personally have an 8GB and I'm considering getting a 16 or above, but 8 is a great size if you have a DECENT music and video collection along with games otherwise I would get a 12GB-32GB if you have tons of media. Click thanks if this helped!

I actually read up on what sd cards perform well as they have benchmark scores on the Toms Hardware site. The Kingston 8gb class 10 is really good. I got around 16 mb/s write speed and 19 mb/s read speed. Not too shaby for $9 on Amazon, and they have the 16gb for $16. Also, if I remember correctly the 16gb performed a little better than the 8gb, but both are perform well.

This right here. While physical stores can also get hit with fake cards, the big dumping ground for cheap chinese knock-offs is ebay and third-party Amazon sellers. Buy one, and you're likely to get a much slower card, the wrong capacity, or just a lump of SD-shaped plastic. you're better off going to wally-world, beastbuys, or a reputable e-tailer like new-egg.
That all said, SD cards are pretty much a commodity item, meaning they're more or less all the same. The Dinc itself I believe can only read around Class 4 speeds, but that's no reason not to go ahead and get a nice fast Class 10 card. Sooner or later you'll probably want to use it in another device or in your PC and it's nice to have the breathing room. I usually buy Sandisk when I buy them, but they're essentially indistinguishable.
And on a tangentially related topic. I see that the Galaxynote 2 is going to be one of the first devices to use SDXC cards... who else is ready to dump 2 terabyte SD cards into their phones to keep their whole lives on? :highfive:

I'm using a genuine 16GB Samsung class 10 card, but I'm not sure if it's any better than alternatives. Just feels better subjectively I guess having a samsung card in a samsung product..
I can say that transfer speeds are quite good, and roms do feel quite fast.

I believe it works, but I'm not sure what kind of benefit you will see on this older hardware above Class 10.. outside of needing to transfer larger files back forth regularly. Performance-wise with custom roms, probably not.
