Article on SD Cards in WinPhones

http://www.theunwired.net/?item=dis...ne-7-memory-management-and-microsd-cards&5674
Seems the HD7 uses a Class 2 SDHC card for its internal memory, which is replaceable. I'm surprised it uses such a slow card.
I suspect replacing the card invalidates the warranty though as you need to unscrew the phone and break a seal to get at the slot. Nevertheless you'd end up with a lot more storage, and even 32GB cards are available at class 4 so would be a fair bit faster too.
I remain hopeful that the Venue Pro has gone for the more expensive route of having its 8GB on internal flash chips, leaving the SD card socket free for that nice beefy 32GB card I'm going to put there.

It is odd how MS's own site said they used advanced microSD cards and thus they would be difficult to replace or something. Then we see it's just a class 2. SanDisks are typically a little faster at lower classes than the rest, though.

Two days ago, it happens here
Come one guys, read more please...
You should check the real source here: how dereckcranson was the first to prove us that we can switch any microSD card in our HD7

Okay, I wonder if there are 2 sd card slots in the Focus. Could we switch the 8GB out for 32 and then put a 32 in the 2nd slot?
That would be awesome but I'd be spending just as much on sd cards as I would the phone on an ATT-2year.
If someone get ahold of one, please check!!!

yes it would work if samsung went the route of adding a sd card instead of flash memory as the internal memory. someone would have to open it and see.

I guess the only folks who could figure this out unti after Nov. 8 are the folks with an Omnia 7. Seems to be pretty similar phone.

[Q] How many people wanted removable storage on a Galaxy Nexus?

Like the title says, I'm curious to see how many people actually wanted this function. I was a bit disappointed when I heard about the lack of removable memory, but I lust after this phone. I do have a 16GB card that's near capacity. I haven't cleaned it out in a while, so I'll do that first. Hopefully 16GB will be enough for me. But I digress, this isn't a rant about how the Galaxy Nexus doesn't have removable memory. This thread is more about seeing the percentage of people who did want this function.

I did want it, just like I wanted it on the NS. But I understand that I don't NEED removable storage and will be buying the GN the first chance I get. And given the choice, I'll probably go with a 16GB version, because I still have about 4GB of free space on my NS.

I really wanted an sdcard slot on it. I will have to import the phone as the 32GB versions as there seems to be no current plans to sell that version in Sweden according to Samsung themselves. 32GB is minimum for me. I had hoped to be able to get a 32 GB version and then plug in my 32 GB microsd for even more storage.

Wanted it, but mostly because i got a 32GB MicroSD card already
All of my storage is wasted on nandroids anyway.

The lack of the card slot (which even my Nexus One has) is a real shame - it would only have cost a few pence to include a card slot unless there is something I have missed. The slot would have been preferred to the barometer by the vast majority of people - if we had to choose one or the other.

If they were releasing the 32GB in the UK i wouldn't have wanted an SD slot as that would be enough for me. But as we're only getting the 16GB for whatever reason i would want an SD.
As they're not doing either i'll have to stay with my GS2.

i know i'm having issues with my card slot and/or SD card on my Fascinate. It'll say my SD card is ejected when it's not. I'm starting to think the omission of a card slot isn't so bad.. less moving parts = less things to break? lol

Not too bothered about it at all, never take my card out of the current phone.

Exactly!
I was a little upset about no SD at first, but then realized that I haven't taken the card out of my N1 since I first got the phone and used it to transfer stuff to the new phone...easy enough to do with a USB and 5 minutes.

Only thing that bums me out is I basically can't get the 16GB because if I run out of space I'm hosed.

You are totally missing the point of the sdcard slot. The biggest advantage is being able to upgrade the amount of storage if you need it. The fact that it costs next to nothing now makes it even better. Also, a less used upside is the ability to read it even if your phone stops turning on at all.
To me, the best solution would be to have lots of internal storage but still have the option of an sdcard for extra storage for movies, lossless audio and other big files if the user wanted. I would be totally fine with it being used entirely for user storage. Any form of cache files that are currently stored on the sdcard probably belongs on the internal memory.

Well you got a small screen so movies shouldnt be large in size and phones probably aren't the best devices to playback lossless audio to make a difference audibly.
I'm pro SD card though but really you just slap a large one in there and forget about it. I do use it as a quick medium to transfer custom roms and kernels to my buddies... pictures to my gf... etc. Seemed transfers were faster directly using the SD card vs going through the phone... but with the cloud and wireless transfer methods, its a mute point.
Most stuff can be in the cloud such as pictures and music and even nandroid backups (only need a few locally). I keep games/apps/wallpapers locally but those could even go to the cloud. As long as I can download them when I need them. And you don't need to have a whole movie collection on you at all times. Just a few throwbacks for travels.
My collection spans since my nexus one and its maybe 4-5gb minus music
G2x - 2.3.7 CM7
Transformer - 3.2 Revolver OC/UV

i got a good collection of 32GB that i parked since i got stuck with Nexus S, i was really hoping GN would have the SD slot
and just purchased a 64GB microSD, with no where to use it on the GN

what am I going to do with my class 10 MicroSD?

I did want it. But I guess its cool that they're selling a 32gb version, just hope it's not an outrageous price. But I've never modded a phone without removable storage before. Either way, I'm buying on launch day.ill be importing from the UK since T-Mobile hasn't said a peep about it and I don't feel like waiting another month or two or three

I've been waiting for the price to drop on this card. Just giving everyone a heads up on a great deal on a fast card.

will our phones support 64gb no problem?
i saw that earlier as well, but hesitant, dont know if phone supports it or not

The phones will support it Just fine. You have to format it and Max file size is limited to just 4gigs, I believe.

Solid card, i have the 16gb version of that and the speeds are insane, def a step up from my class 4 sd card

Yes, yes, but it's still quite odd; you don't often hear about manufacturers/carriers underestimating their own devices.
In other words, has anyone actually tried filling a 64GB card to max capacity with data on the phone itself? Or is it only addressing the first 32GB like I would expect? Just because the card happens to be readable doesn't mean it's actually fully working like it should, so I'd still be wary about landing the money on a 64GB card for a phone that Sprint claims supports up to only 32GB.
If it *is* only addressing the first 32GB, then the only remotely possible option to get the full 64GB capacity is to re-partition the external SD as two 32GB (roughly; probably a little less) partitions. However, that's a *very* big "if" as to whether or not that actually works, since SD cards (and other flash-based external memory devices like USB thumbdrives) are designed (and expected) to have only one large partition. Similarly, you'd have to do some serious modding to get both partitions mounted (if the phone's card reader itself isn't the limitation).
In all likelihood, even that above solution would probably not work due to hardware/firmware limitations. This is similar to giving older computers big hard drives; even though the hard drive will certainly be usable, many older BIOSes are incapable of accessing anything beyond a certain capacity (in the case of an old Compaq laptop I have, that limit would be 10GB).
tl;dr: don't assume that the ability to mount the SD card automatically means all the space on it is accessible from the phone.

i ordered this card after seeing this thread.
it came in today.
i cant get the phone to read it.
i formatted it and tried everything.

It's never ALL accessible whether it's supported or not whether it's computer phone or any device. Making two partitions would have you lose even more space and isn't necessary, once card is formatted to FAT32 it WILL work people.

I have been thinking alot about getting a new card.But after I looked more into it 32gb is a max. I could really not use up 64 gb unless I am loading it up with my girl's Disney movies and Transformers G1 episodes.
With 16gb internal and 32gb ext. that would be more than adequate,cause most of the time i am transferring data back to my PC. Especially backups and ROMS.

I think you misunderstood what I'm saying. Splitting into two partitions will create some overhead with additional file allocation tables and partition data, sure, but it's nothing compared to losing half of your card's capacity because the device you're using the card on isn't capable of addressing past the 32GB mark. There's a difference between "it'll work" and "it'll work correctly", and in this case that difference is 32GB of potentially-inaccessible capacity.
So, I reiterate: has anyone verified that the phone is capable of reading and writing to the entire capacity of the card? Does it recognize the card's capacity to be 64GB (or something close)? Does writing more than 32GB worth of files actually work, or does the operation fail (or worse, overwrite data)? I'll see if I can get my hands on one of these cards so I can perform this kind of test, but until someone confirms this, it would be wise to maintain some healthy skepticism, lest you buy a fancy 64GB card just to figure out that it works no better than a 32GB card.

It has been verified by a few users in this thread already as well as others. Read a bit of this http://forum.xda-developers.com/showthread.php?t=1799634(as long as it is an actual SanDisk card then there is no reason to worry) it will work.

HTC 10: A devourer of SD cards?

Hi!
Today my SD card died and took some pictures with it to the grave, fortunately nothing very important. It may not have been the most expensive card, but it was a fast one and I used it as internal storage. It didn't show any signs of deterioration before it died. I tried to read the card with my PC and two tablets but none of my devices is able to even see the card.
Before buying a new SD card I want to ask a few things:
Does the HTC 10 have more problems with SD cards than other phones in your opinion?
Should I use my new card as internal storage again or do you recommend to use it as external storage?
Is it worthwhile to buy an expensive card? I laid my eyes on this one: SDSQXCG-064G-GN6MA (SanDisk Extreme PRO microSDXC Memory Card Plus SD Adapter up to 100 MB/s, Class 10, U3, V30, A1 - 64 GB). It costs about 50€.
I hope that you want to share your thoughts with me.
Regards,
Benjamin

If the card was inexpensive and fast, I would think that the compromise made was on build quality/reliability. Using the card as internal storage will wear on the sdcard more than using it as external storage (more reads/writes, more heat) because it will store apps and app data on the sd card.
I don't think the HTC 10 has a problem with sd cards, I haven't heard this issue come up before.
If you have enough space for apps on the internal storage, I would recommend keeping the sd card as external storage.
However, if you still need to use a card as internal storage, you definitely want to get a more expensive card.
Sandisk extreme pro is a good choice because it's made for use with devices like GoPros that do constant writing for extended periods of time, meaning that they can handle the heat that builds up when constantly writing to the sd card.
Sometimes it could really just be pure chance, maybe you got a bad card that died early, but I definitely think it would have lasted longer as external storage.
I'd be interested to know if anyone else has had a similar problem with any phone with an sd card as internal storage.

The thing is - current sd card technology is not suitable for adoptable storage. Multiple read write proceses are killing memory cards. So, until someone makes a card that can take the beating of multiple read write proceses, just use your card as it's ment to be used - as a removable storage and you'll be just fine [emoji6]

Thank you both for your well formulated and competent response.
I've taken all these points into consideration when I chose to use my first SD card as internal storage. I really would like to know if a high quality card could last the expected lifetime of my HTC 10 when using it as internal storage. I wanted to avoid the limitations Google imposed on write access to the external card but when I saw the limitations of the internal storage solution I was unsure if it was a good decision.
It's good to hear that you do not have the experience that the HTC 10 has a problem with SD cards. With that information in mind I can buy an expensive SD card with good conscience.

Let's hope that more users are going to share their opinion with us.

I've just sent back my second SanDisk Extreme PRO card in 18 months. The first one stopped working after just 4 months in the HTC 10, the second one a few weeks ago. The circumstances were identical, I wrote larger amounts of data in a short time and the phone started saying that the card has to be formatted. I could use a reader connected to my laptop to get most of my data back, but the phone insisted on a format. I'm not sure if it was the SanDisk cards or the phone, either way, I ordered a Samsung card this time. Luckily amazon.de is extremely customer friendly and just gave me my money back in both cases.

I always use transcend, I've had a 128gb external SD card in since may 2016, all camera shots goto external card, all flashing and backups goto external card. Never had a problem, touch wood ?

Guys, are any of you using Spotify? I have consistently had microSD cards die after downloading songs for offline use i.e. two phones and three different microSD cards.

I use a Samsung evo card as removable storage since January, never had any problems with it. They are a bit more expensive, but it is worth it in my opinion. I use it mainly for Spotify and Netflix downloads as well as pictures (wallpapers) and ringtones... Don't use a rather inexpensive card as adoptable storage, since they are too slow. Or even expensive cards for that matter In a few years, sd cards will be fast enough, but not today. Also, I fail to see a practical use for using the card as adoptable storage as of right now since 32 gb are plenty of space for apps

I'm going to buy a card produced by a reputable company this time, for sure. But I thought that cards with the A1 specification (Application performance class] would be fast enough for use as adopted storage. But you are right, 32 Gb is a lot of space for apps.

I've used Samsung evo and Sandisk Ultra Extreme and the both failed a short time after downloading Spotify songs!

I've had a Transcend 64GB card fail after a few months. It was inserted as external storage and I was able to recover its contents on a PC. I was able to put it back in the phone without formatting it, just tried a few times until eventually it worked.
It happened when it was very hot outside, not sure if this is related or not. I wonder how many failed cards are failing during hot weather, during heavy phone use, or in hot climate areas.
I've switched to a Samsung 128GB evo plus now, u3 speed, so far so good. Fingers crossed. Judging by this thread though, it does seem that this phone kind of eats through SD cards.

This is precisely what I wanted to know in this thread. Before buying my first card for the HTC 10 I read a number of threads that suggested this phone specifically has problems with cards bigger than 64 GB. But the reaction to my thread doesn't seem to be so hysterical to me.

I been using a Toshiba Exceria M302 128GB as external storage since the phone first launched and it hasn't failed on me yet, touchwood. Although I only been using up to around 50GB usage, I have re-download my Spotify collection a couple times.

The SD card in my HTC 10 is going on 15 months old, and it's still ticking. I have never used it as adaptive storage. It just stores photos taken on the camera (which are backed up to Google Photos). Some games offer to save data onto the SD card, so I do that as well. It's a Samsung 64GB PRO (class 10).
Not sure if the UHS-1/3 cards will fare better.

Maximum Memory Card Size For 5T?

I think you should tread the 5T specs first.

The 5T does not have expandable storage.

That's a more helpful answer than the first one, thanks.

damn, why it was so difficult for onplus to make 3rd slot for microsd, always something missing !!
since my first android phone, they always did that !!

Because they want to lost the money from you, just because you buy a memory card, instead of buying a phone with bigger storage from they. Memory card is slower than the phone storage. Just two examples, why they make this decision. The 3rd... the need extra space, for the memory card tray...I know, yes, you say that there is also space on the tray, if you decide to use just one sim... But you need a READER PART TOO... that's extra space... It's better to get a memory card slot for it, but a smaller battery?? I don't think so.

Hey Ben,
This is a little old question but I've just started using the OnePlus 5T a couple of months ago. You can use larger memory sticks and disk drives. But you'll need to convert to FAT32 format first. I just did this with a SanDisk 64gb stick and works great. I think my 128gb 5T is large enough but great to have extra space for movies on flights. If you haven't already sorted this out, I'll be happy to provide you with more information.

its actually because the SD cards memory runs way slower than the phones built in storage memory and would bottleneck your phone. and why on gods green earth would you even need more than 128GB? one solution would be to buy a USB type c memory stick, on that well known auction site they sell at 64gb= £10 or 128gb - £15 as previously mentioned format them to fat32 to make them compatible. most come with type c connector on one end and normal usb the other
