32 gb micro sd card

anybody has experience with one of these?
does it slow down the htc hero??
i have a lot of music on my hero and i notice everytime the hero needs to access the sd card it lags a bit, i notice it when i open albums and when i open my music library it lags for a little like if it scans the whole sd card first,
so im thinking the more space the sd card has the more it will lag for these things, anybody got one and can share their experience?

More space != more lag
If you have a faster card it MIGHT have a better chance at faster access. So a class 2 card might seem slow compared with a class 6 card. I haven't seen a definitive test performed on the Hero and the different card classes throughput though.
A card with equal throughput (class speed) will require approximately equal lag time whether the card is a 2gb, 32gb, or anything in between.

Since this is on the topic of sd card, where's the cheapest place to get these?
I've found 8gb class 6 cards on Amazon, but as for 16gb and 32 gb class 6, it seems a little ridiculous in price difference.

Excerpt:
This is what HTC told me [when I asked what class card to purchase]:
"Good Morning Frank,
Thank you for taking the time to contact HTC America Technical Support via E-Mail with your inquiry about what class of SD card to use in your Sprint HTC Hero. My name is A.J. and I will be happy to assist you today.
If you are looking to purchase an SD card that the device will read at its full native speed you will need to purchase a class 2. The device will read a class 4 but not at its native speeds.
Frank, if you have any future questions about your device please feel free to visit HTC - Touch Phone, PDA Phone, Smartphone, Mobile Computer and send us another e-mail. You may also enjoy HTC Smartphone Wiki - HTC, which has a plethora of information on HTC devices, including the Sprint HTC Hero! I would also like to invite you to participate in a customer satisfaction survey located at HTC Online Survey I hope you have a great day!
HTC America Technical Support
A.J."

So it looks like the HTC Hero will read class 2, 4 and 6, but not at the native speeds for 4 and 6. So it seems like a moot point of "what class to buy" if the data bus isn't going to take advantage of a faster card.

I am becoming more and more disappointed with HTC and sprint. Too many factors being left on the table for my taste.

well is that a hardware or software aspect of the hero?

It's a hardware aspect, like our cpu and ram.

has this been verified by any benchmarks or can it be? i'm thinking about jumping off on a bigger card, just haven't seen anything definitive about it

i've heard severa people report speed increases by using class 4 or 6 cards. Might not be native speeds but faster than class 2... just a thought.

Currently I'm using a kingston class 4 and the speed difference in loading music or pics off the card is not noticable. I got it for APPS2SD and Linux Swap whenever someone decides to utilize it in a rom.

Can someone post a link to a 32GB card? I can only find dual 16s from Tropam.
I thought San Disk wasn't releasing the 32 GB stuff until next year because they are hit/miss on full storage capacity still.
EDIT:
this year I guess...lol.

tbh i can't find one either... maybe they aren't even released yet? i will keep looking
on my question though...
is there, or can there be, an app that reads/writes test files from the microsd card and tells you how long it took to read/write.... you know, a benchmark... seems the only way to be able to tell if there is a real diff between the classes

from wikipedia
"In February 2009 Sandisk also announced a 32 GB version for the second half of 2009,http://en.wikipedia.org/wiki/MicroSD#cite_note-4 but as per end December 2009 it is not listed yet."

The Hero has no problem significantly exceeding the capabilities of a Class 2 card.
Using the C2 card the phone came with, Windows 7 reports reads maxing out at about 3 MB/s. Using a C6 card that I bought, Win7 reads at 10 MB/s and writes at 6.5 MB/s.

if anyone experienced in java wants to take a crack at it, maybe they could write a native app to benchmark r/w speeds of our sd cards. I think that would be rather handy to have even if it was limited in usefulness.

No, because it's using the phone's hardware. I'm not taking the card out of the phone - I'm plugging the phone into the computer.
I ran some benchmark program called ATTO or something last night, and it was consistently giving me 5 MB/s with the Class 6 card and 2.5-3 MB/s with the Class 2.

That makes sense.. but HTC still refuses to say that it will take advantage of it.. but an "in Phone" app to seal the deal would be great.

right, it's still in the phone, but the phone isn't reading or writing the card, your computer's OS is, while the card is mounted... acting like a usb flash drive... someone correct me if i am wrong...
was the ATTO prog on your pc/mac or on your phone?
thanks

The contention is that the card-reading hardware in the phone is incapable of read/write speeds greater than "class 2" speeds. The OS has no card writing speed limitations built-in.

[Q] SD card help for running Android? Special File System/Format/Type?

Hi guys,
Lately ive been trying to get Android running on my HD2…
Ive successfully flashed the HD2 to android friendly ROMs, and installed versions of Android to my SD card… but I cannot get it to run.
I have read some things about needing a certain SD (file system, or a certain type of card/partion size?)… can someone please tell me if my SD card is android compatible… if I can just format it or if I need another card?
The SD card I have is a SanDisk 16GB MicroSDHC. I thought I heard something about needing a “Level/Class 4” or something, but I don’t know what that means.
I hope this question makes enough sense, and someone can break it down for me.
Any help is greatly appreciated.
Cheers.

your sd card is fine. I've ran many android builds off that microSD, which if I'm assuming correctly is the one that comes with the HD2. Do a full format, not quick (so uncheck that box in windows). The preferred allocation size is 32k. If that doesn't work try formatting with SDFormatter

Thanks for your reply mate.
It is the SD card that came with my HD2, but I have the Telstra Version (T9193), so im not sure if it shipped with the same SD card world-wide.
I have just done some more research on the Class/Level Numbers of these SD cards, and I think the Class/Level Number is marked on the card with a circle around it, if that’s the case I have a Class/Level 2 card.
Thanks again for your reply, hopefully once I format the card, I will have more success than I had previously had.
Cheers.

one more thing though... what filesystem should i format the card to?
cheers.

FAT32, always
Edit: Yes, SanDisk class 2 is the same card mine came with. I've heard of some people getting them with 2GB cards, but I think for the most part 16GB calss 2 are what most people got.

no problem, thank you for your help.

it says right on the box it comes with a 16gb sd card.. if yours came with something else then the rep or the store owner took the 16gb card out and replaced it.
some shady stores would do this and try to sell you the card it came with.

Tmous got 16gb cards. Euro got 2gb ones.

Corrections, and swift answer
Firstly, flash storage devices marked as class 2 or class 4 would have nothing to do with comptibilty. Flash storage classes are the specifications of the maximum theoretical limit transfer speeds for that type of flash storage device. Take a look at this wiki article to learn more at wiki secure digital class rating article. Next, the type of storage device needs to be specified as microSD rather than SD since they are different flash types. And lastly the proper terms for storage sizes need to be used. GB means Gigabyte which is 1x10^9 bytes or 8x10^9 bits as 8 bits=1 byte, and Gb is Gigabit. The problem doesn't lie in the syntax or intended use of, it lies in the dumbing down, so should someone be wanting to learn these things they are getting taught wrong.
And for the swift answer, no class never makes a difference on compatiblity just whether it has the suffix HC or not, which stands for High Capacity as is reserved for any storage amount of 4GB to 32GB in which case is goes to XC which stands for extreme capactity and is reserved for 64GB to 2TB(TB=terabytes). The only reason this matters is each type of suffix is actually signifying a new type of transfer protocol which requires a firmware upgrade to read the new format(key work firmware not hardware, as one example even the oldest SD card reader could read a 128GB card with a proper firmware upgrade, albiet at lower transfer rates). And the format fat32 is typically used as the standard external storage filesystem.
I hope this answers any and all questions, always remember, what your writing doesn't just apply to you and your not the only one involved. Your words reflect like a butterflies wings.

Sandisk 64Gb microSDXC : have anyone tryed already?

Guys, newest sandisk 64gb microSDXC will fit Defy?
http://www.sandisk.com/products/mobile1-memory-products/sandisk-ultra-microsdxc-card

It will fit in nicely becuse it is the same size as the microSDHC.
It doesnt work out of box ;you have to format it in the phone..then you' ll get 59 GB of free space.
No, i dont have it but i have read about it and it works in htc,samsung..

According to specs, memory is upgrade-able only to 32gb.
Will a 64gb card work?

I think you should take the risk and test it yourself

So does it work? That´s a very nice sd card

the defy supports 32gb sd official. 64 gb not supported. I think for any phone 16gb is stable for space and speed. how do they fill up 32gb?!

There are also reports that they are working on many older devices for those wondering. Some include the EVO 4G, original Galaxy S, and even the HTC Desire Z (aka T-Mobile G2). With both old and new, smartphones and tablets being able to take advantage of the 64GB SD cards this is a good sign many more will have the same fate. We can only assume manufacturers didn’t state SDXC support because none were out on the market at time of launch, or maybe there are other reasons yet unknown.
At first insert the device may say corrupt or error, just reformat your 64GB card inside the Android phone or tablet and you’re good to go. While many are currently working, this doesn’t mean they have full support. The chance of the cards failing, getting errors, and possibly losing all your stored data is still a possibility so use at your own risk for now. Hopefully we see more 64GB SDXC cards soon and at lower prices because $219 is a bit steep for me. — Thanks Murray!

SDXC cards use exfat file system. If defy doesnt support that then it probably wont work.
Ive seen reports of it being working on a lot of phones, so there's a chance it might work on defy, but the card needs to be formatted on pc first before using on phone and it wont work at full speed due to limitation on the old sdhc reader (sdxc reader is faster)

I'm asking to avoid risks ).
Why 64gb? Cause i have 32gb card and it have about 4gb left. Actually last few month i've forced to clean up card from time to time. Audiobooks, DVR, Navigation software, record lections on dictaphone... That stuff takes space but i've used not to worry about `if do i have avaliable space left` ). Also this card declares class 6, now i own Sandisk/32gb class 2, so it not just larger, it laso should be faster. Sometimes DVR+Navigation provides some lags, for example.

maybe the max is 32GB,class 10

you can buy but i thin you will see only 32gb space...

can defy uses class 10 sd card? i heard there is problem in taking picture with class 10 card...

read posts on XDA, yes it has a problem with 6 and 10 class

CM7 and miui can run fine class 10 cards now.

SDXC on Defy?
It really works on Defy. I own one for a month now. Cost 80€/106$. Absolutely no problems after format. 59GB free. About 6MB/s write, 16MB/s read speed. Have fun.

Greater than 32Gb?
Biggest I've used is a 32Gb class 10. No problems at all.

Android police posted a review. Looks good.

This is funny yet strange. Why you think an article on a website has more truth than a forum post of a member? Both are written by a single person. Both can be faked or real.
The guy on the website used a newer Tegra device so his article is irrelevant for Defy users. The SDXC in my Defy works flawlessly for weeks now with 20GB free space left.
Of course you can ignore this. I don't care. But if you need space buy the SDXC and have fun.

That's strange, is there big difference between supporting 32gb and 64gb? I would have thought that when in development they would have made sure it supported the largest microsd on the market. 64gb (59) would be nice to have.

well, i googled, thanks for making me second-guess myself. here's your answer.
http://forums.androidcentral.com/acer-iconia-a500/141186-64gb-external-microsd-card.html

Yep. Others here have said that it works. It just won't work with FAT due to the limits of the FS. FAT32 or NTFS will work.

Guys,
I have used this SD card for months and it works like a champ. All I had to do was to format the SD in another device since the A500 has no provision for formatting a SD card. I formatted mine in my Galaxy S II, Epic 4G Touch(my first 64G SD Card went in this device anyway). Since then neither device has skipped a beat. The SD cards are expensive though. So be very careful taking them out of your device. ALWAYS unmount it or Eject it within file mgr before removing it. Also handle with care. More questions? Just ask...
Update: That's right! You don't have to unmount or eject it after use in the A500. As a matter of fact there's NO option to do so... But if you use it in another device you may need to unmount or eject it.

Just to add to the information given, a few weeks ago I bought from Woot a "Centon 64Gb Class 10" SDXC card (not micro...full size) for $55 and am using it happily with my A500. I use it with a Targus USB card reader and attach it to the full size USB port on the A500. The only snag which occurred originally was that I used "SD's" own application to format it and it would only format in "Ext", this turned out to be unreadable by the A500 but I resolved the problem by formatting the card in Windows as Fat32. This now works fine and given the size you can put on as many movies as you wish.
Just to add to what ojones838 said above.....Generally speaking the A500 will automatically mount external SD storage or USB storage as soon as it is plugged in (at least this is true of my ICS rom) but it's wise to "Unmount" the storage media before removing it.

Just for future reference, the hardware and software limitations for size are 32GB (FAT and SDHC) and 2TB (SDXC). Nothing in-between those.

Just picked one of these up from eBay. Thanks for pointing these out and the details on how to format and use it on the A500 !
FYI - Just ran SD Card Tester on it and it ran at 5.91MB/s Write and 9.19MB/s Read. So inline with expectations for a class 6 card.

@saeba.....Glad the card works for you, as I said above with that amount of usable space you can put as many movies (including large size blu-ray's) as you want. Certainly enough to keep me happy on my transatlantic flights!
Thanks for the info re the speed test, class 6 seemed to me about right.....have learn't to take maker's claims about speed with a grain of salt.

[Q] Note 3 Not Reading New SDHC Card ...

I was excited to receive the 64 GB Micro SDHC card (Samsung microSDXC UHS-I Card Pro) for my Samsung Galaxy Note 3. Now very disappointed ... I put the card in my iBook G4, but it would not read it. Option to Eject or Format, so I tried formatting Mac OS. Phone would NOT read card. Then formatted DOS. Phone still will not read card.
Last, my Note 3 formatted the card, but now my Mac will not read the card!!! The only way that I can load files onto the card is from my iBook. ALL, yes every single one, of my other SD and SDHC cards are readable with my Samsung Galaxy Note 3, so I can load files onto the phone.
Is there a Hidden Secret to getting this card to work with my Samsung Galaxy Note 3, or is the card simply defective?
-- Jim ....

I think that the problem is mac OS and not the note3, because it read correctly the content of micro sdhc card.
What version of Mac osx do you have ?
Have you tried to view the micro SD in a windows o.s.?

So let me get this straight:
1, You placed card in your G4, but does not read and only gives you the option to Eject or Format.
2, You formatted the card in Mac OS (Extended) (I assume from what you're saying) which didn't work and the phone was still unable to read it.
3. You tried the DOS format, the phone will still not read the card.
4. You formatted the card in your phone but the Mac doesn't read it.
I noticed you formatted the card in Mac OS (Extended) format, which is Mac's own file format. Have you tried formatting in FAT32? That's usually the most chosen file format for SD cards. The only limitation is the 4GB file limit.

They have no clue what they're talking about. I've seen many people saying they're running class 10 cards flawlessly. And with such a relatively new device, not supporting class 10 would be an absolute idiotic move.

That is total nonsense, class 6 card will have a problem record even HD video, not to mention 4k video, I have 32 GB class 10card and works fine, I saw many people using fastest cards available without a problem, in other words Note 3 works fine with class 10 cards. You already have an answer, your problem is your proprietary MAC and since Apple's iphones and ipods don't support SD card, you may be up the creek without a paddle. I wonder if your Note 3 didn't format the card as ExFat, it was recommended to me, since it does support over 4GB file limit and it works better in large cards. I'm sure you could transfer files using Apple's approved way, using Cloud and maybe itunes.

When samsung say class 10 is not supported is it class 10 64gb not supported maybe. Considering my 32gb class 10 works a treat

The card might still be defective but I seriously doubt that (since the Note 3 can format it just fine; also there are about a million users of 64GB cards on Samsung phones and those tend to work OK).
Your problem (other than not really reading stuff on your own - for instance you missed on how Questions should NOT go in General forum) seems to be more with using a pretty closed ecosystem (Apple) and some not very fresh versions of it
The short version is that SD cards over 32GB have as standard format exFAT (a format that for instance has the large advantage over FAT32 that can use files bigger than 2 GB). That format is not well supported on older OS versions - which explains why you can't see it on your PCs.
More reading on the subject and how to achieve better compatibility (at the expense of no longer being able to have files over 2GB):

How about you find yourself a Windows or Linux pc and format it to FAT32 or EXFAT there...
Mac OS. Tsk. There's your problem.

Your main problem is your mac G4... It probably has no support for extfat (file system used by default on a 64GB card)... And probably no correct support for sdxc cards.
I've used my Samsung pro card in my 2011 MacBook pro and note 3 without any problem for a few weeks now.

thats a bit of a generalization mac os is and isn't his problem it is because he is using a very old version on his g4 mac however as most people will not have that version any modern version of mac os from 10.6 onwards will work and allow formatting in exfat
also to all the other posters who call mac os a closed ecosystem and generally dismiss out of hand mac os where is it anymore closed than microsoft systems ??
i can and do run both os on a cpl of mac pros (mac/win) and a cpl of intel pcs (win/mac) .......my os of choice however is mac
to transfer files on mac os use android file transfer ...however this will not work on non intel macs

Well, you can run Windows on your Mac, no Windows computer can run Mac OS and it's not for any particular technical reason, but because it's locked to hardware, so yeah, Windows is open and mac is locked OS, no matter how you look at it. And generalization or not HIS MAC IS THE PROBLEM, not Note3, regardless of the reason.
