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?

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?

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.

[Q] 1GB ROM & 8GB internal memory?

Is WP7 OS stored in the onboard 1 GB ROM?
Is the 8 GB internal memory on a microSD card?

The 8GB is internal. There is an empty MicroSD slot in the back to upgrade the phone by an additional maximum of 32GB. However, you may want to check this out:
http://forum.xda-developers.com/showthread.php?t=834144

When the people on the gadget blogs open WP7 devices up, they have generally been finding SanDisk class 4 cards hidden inside. I think only the Optimus 7 was found to be using flash nand so far. Haven't seen a teardown for the Focus yet, but if I had to bet $5 on it, I'd say there's a microsd card in there for the 8gb included storage.

Actually no, I don't where you get your conclusion from. So far, only HTC phones appear to have internal SD cards. Samsungs are NAND chips only. There is a tear down thread for Focus's international cusin, Omnia 7 in Omnia 7 section of this forum.

Oh, wow, that both makes me happier about my purchase and disappointed in HTC at the same time. You shoulda taken me up on that bet; you'd have $5!

You can see the focus in detail here: http://pocketnow.com/windows-phone/samsung-focus-review. Mine didn't come with a card, so the MicroSD I added was additional memory.

Samsung supplies NAND flash chips for majority of flash cards out there. It makes no sense for Samsung to use someone else's microSD cards (with its NAND chips inside) instead of its own NAND chip directly.

No one has tear down a Focus yet. That review, alone with others, just shows the back side of the phone. A tear down needs to disassemble everything and show photos of the circuit board.

[REQ] exFAT/microSDXC support

I've had my SGS2 for almost 4 months now, running KE7 firmware. Within the next few hours, I'll be getting the SanDisk 64GB microSDXC card, and I'd like to use it in my SGS2.
Based on my reading of other threads in this forum relating to microSDXC support, it's my understanding that the SGS2 hardware will support this card, but that software support will be required to handle the exFAT filesystem, which is the standard format for microSDXC cards.
To determine if exFAT support existed, I did a test last night, formatting a known-good 16GB microSDHC with exFAT and mounting it on my SGS2. However, when the phone powered up and scanned the card for media, it reported that the card couldn't be read and offered me the option of formatting it with FAT32. That suggests to me that the firmware expects micro SD cards to be formatted only as FAT32.
Again, from reading other threads on the forum, mostly related to NTFS support, it sounds like it should be possible to modify the firmware to support exFAT-formatted microSD cards. So I have two questions/requests:
Does a custom firmware package supporting the exFAT filesystem for microSD cards already exist?
If not, would one of the devs like to take a shot at making one?
If this mod hasn't already been made, I'd be more than willing to assist the devs in any way I can. I've been a software developer for almost 25 years, but almost all of my experience is in Windows, and is pretty much evenly split between user & kernel mode, so I know a thing or two about filesystems & drivers.
The last time I did anything in the Unix kernel was back in the days of AT&T SVR4 and SunOS, when Linus was just beginning to develop the Linux kernel. So doing this myself is a bit of a stretch, which is why I'm asking for help from the dev community.
Any help I get would be greatly appreciated.

You would need to grab the kernel source, from samsung or a custom kernel, then build it with fuse support and the correct file system module, or just with extfat support if fuse doesn't have the correct module, the cm7 wiki has a good guide to building kernels then combining them with a ramdisk.
You would need to use a ramdisk from a stock kernel for it to work with stock roms.

Easy for you to say -- my last Unix experience was 20 years ago.
Anyway, I just took delivery on the card. When I stuck it in the SGS2, it offered to reformat it as FAT32, which I did. Once formatted as FAT32, the card appears to work pretty well. SDTools gives read/write speeds of 18 MB/s and 6.6 MB/s respectively; that suggests that the SGS2 is the roadblock, since the card is supposed to handle 30 MB/s reads.
Still, it'd be nice to have exFAT support, so we can use the microSDXC cards as they come from the factory, and to allow for file sizes > 4GB for DVD/BluRay rips and other HD video formats.

Haha, it's easy to say but it's not that easy unless you are experienced in this kinda stuff.
I couldn't easily do it myself or i would
Sent from my GT-I9100 using xda premium

do you wanna say that microSDXC already supported by stock SGSII kernel?
How much free space on this card SGSII shows after format to FAT32?

In stock ROM SGSII supports up to 32GB SDHC, it won't support 64GB SDXC cards, regardless the file system format.

MicroSDXC is working on my SGS2. I've been running the SanDisk 64GB microSDXC in my phone all day. I had to reformat it to FAT32, but it's working fine.
The card shows up as having a capacity of 59.46 GB, and SDTools shows read/write speeds of 18.0 MB/s and 6.6 MB/s respectively. I've played both MP3 and videos off the card, without any problems.
I'll beat on it some more over the weekend, but all signs seem to indicate that microSDXC works as long as you reformat it to use the FAT32 filesystem.

read/write speeds of 18.0 MB/s and 6.6 MB/s respectively

For a class 6 card its normal , read is very good actually close to class 10. My 32GB class 10 Adata Reads 21.3 MB/s Write 15.5 MB/s.
That claim of 30MB/s might be with exFAT or plain BS marketing claims. Anyways i ordered one also 64GB is god send for media storage.

Ordered mine too, will post feedback when I get it (although hopefully loads of other people will have confirmed by then too).

To be honest, i dunno what id use that much space for, i dont think id ever fill a 32GB SD let alone that monster!
There was a time when id have dual booted android, but i cant be bothered with all that now WP is pretty much perfect on the HD2,

Hi.... Just wondering... Did you experience any change in battery drain and smooth running of the rom after installing 64gig sd card ,
And which rom unr using currently...

This is epic for someone like me! I'm one of those people that fills up 16 gigs in no time flat! 32 sounds nice, but 64 gigs!!!! I'm in heaven, I need to get one. How much did the 64gb card cost you?

Any updates on whether this works yet? I would like to upgrade from 32Gb soon.

THing with Radios is that firstly we have 2 different radios to deal with, and secondly different networks and signal strength areas will do better with different radios, so you may find that the latest and greatest radio is actually worse than the first radio available because its been stripped from a phone on say, the O2 network.
Trial and error appears to be the best, or ask folk on your network what they use, ideally in your own country and even better near you,

SDXC
Basically... All SDXC cards will work...
The thing is, this is how the cards are supposed to be shipped:
SD => FAT
SDHC => FAT32
SDXC => exFAT
Any SDXC card can be formatted as FAT32 to work with SDHC compatible devices. The OS "decides" how much of the storage capacity can actually be allocated.
Since microsoft probably took note of SDXC during development, windows phone uses a file format that either supports exFAT (which is a MS file format) or formats the cards in a file system that supports over 64gigs. Windows phone supports SD cards under 32 gig, so it supports FAT32 and FAT anyways (to be reformatted in the device)
Long story short, as soon as a device supports exFAT it is SDXC compatible. if a device supports FAT32, any SD card formatted in FAT32 works.

Will the 64GB SDXC card work with the original Windows Mobile 6.5 ?
Does exFAT work on WM6.5?

Wohooooo 64 Gb for what?

In regards to the SanDisk Ultra 64GB SDXC...over the last couple of days I installed the NexusHD2 v2.3 and set the card up with 8GB EXT4 and 52GB FAT32. It ran slightly slower than NAND but I adjusted the CPU speed to compensate and overall a darn good experience. My next adventure was to dual boot both NexusHD2 and Pdaimatejam's WP7.8 and I split the card pretty much right down the middle taken into account the 200MB FAT32 WP7.8 creates upon it being deleted and for one brief moment you have only 2 partitions before continuing to create the EXT4 partition. WP7.8 will works up to a point and then begins the reboot loop. I understand there's a way to image a smaller memory card onto the 64 gig card and that's what I will be doing next. In the meanwhile I did successfully load Pdaimatejam's ROM into NAND but the key here is that card must be formatted as exFAT; otherwise it too will reboot endlessly. My only use for Android are CoPilot Navigation and Google Navigation and Skype; otherwise I prefer Windows Phone for one reason and one only; it runs as smooth as silk but WP7.8 lacks what WP8.x now haves...good GPS Navs, what my Titans and HD2 have is customization and that is a sticking point for me in regards to upgrading to the Lumia 92x series.
