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.

Phone says damaged external SD card? (32GB Lexar Class 10)

Brand: Lexar 32GB Class 10
(I'm a big fan of Lexar. After my personal experience with prior Lexar SD chips in my previous phones and after countless hours of research, I'm loyal to Lexar. So the brand isn't the issue.)
I take lots and lots of pictures and video.
I had over 3000 photos on my phone and a few 1080p video.
I play xplane simulator game a lot and after a while the phone can get pretty warm.
So I'm thinking...(I do have a case on the phone as well.)
Could the heat from playing the game be responsible for the error message I'm receiving?
It said something along the lines of, "Damaged external SD storage..."
Right now I'm recovering the files and reformatting the card.
Now I'm a little gun shy to put it back in even after reformatting, because I don't know if it'll go out on me again...
I don't see any physical damage so it has to be file corruption caused by heat?

i have a Class 4 32GB Lexar, it is okay, not my favourite, too slow for my taste
have you tried re-partitioning the disk and formatting it?
i've been using a 32GB ADATA class 10 on my T989 for 2 weeks now, one night i left some game running for 10+ hour after i passed out playing the game and when i woke up the phone was burning at 50c
all my stuff are still in good shape in my SD card and phone itself
so, IMO i think your card was not affected by the heat, rather it's just wearing out, or it just needed a clean up
You do know Flash storage have limited writes, right?
it's not like a PC hard drive with unlimited rewrites

It's very normal for a 32G class 10 card to have problems. Look at newegg or amazon reviews. All class 10 cards (any brand) has a LOT of complaints saying card died. So I avoid putting important stuff in SD card altogether.

rather than avoid, you should keep multiple backups of important stuff
that's why i keep multiple copies of my SD cards

32GB SD Card issues with Galaxy S2
Hi all,
Got a similar problem here.
Transcend Class 10 32GB Card
Works in PC, HTC Desire - no probs.
Put in Galaxy S2, it starts Media Scanning, a few seconds later reports SD Card Damaged, requires formatting.
It's right - take it back out (again, umpteenth time!), put it in PC or HTC - card is "damaged". (Nothing permanent, can reformat.)
Samsung support claim to not know anything - mind you they "play dumb" about the camera "pink spot" issue, until you challenge them to get real...
Oh, dear!

External SD vs. cold temperatures (solved)

Guess this is mostly a canadian concern, but has anyone else's external SD mysteriously been deactivated when the phone is exposed to temperatures below freezing for relatively long periods of time ?
For example, taking a walk outside for +/- 30 minutes when the temperature is around -10°C (~ 14°F).
It behaves exactly as if it's being manually deactivated in Setting --> Storage.
The card comes back to life after leaving the phone untouched for 5 minutes on the table upon returning to "normal" room temperature (~ 21°C / 70°F).
Never encountered this issue with the exact same SD card in my good ol' GS1 (i9000m), so I'm wonderring if it's the GS3 that doesn't tolerate the cold very well of if it's my SD card that's getting old.
---
EDIT
It was indeed the external SD card that seemed to be the problem. Switched temporarily to a 16Gb SD from my old GS1 i9000m and couldn't reproduce. Have bought a Sandisk Ultra 64Gb Class 10 micro SD card since then and couldn't reproduce with it either.
Glad it's not the phone! :victory:

Re: External SD vs. cold temperatures
I've had stuff like this happen, (Canadian as well). I always thought it was due to moisture but it's never been a big issue
Sent from my SGH-I747 using xda premium

Normal Operating Temperatures for SD Cards are: -13ºF to 185ºF (-25ºC to 85ºC)
There's a possibility that the SIII can't read the SD cards under cold conditions?
I'm not 100% sure, as I've only owned my S3 for a week and a half, and still playing and tweaking it..
I also live in Canada (Montreal), so our weather conditions are about the same.. So i will let you know if i encounter this problem or not?
I would try to re-format your card?? maybe that will help??
Use the Panasonic SD Formatter Software for Windows, and then I format inside my S3 for best performance.
Try that, maybe it will help???

It's an issue when :
Your camera is set to record images/videos on that SD card and you want to use it
You meet someone on your way and want to show that person pictures you've taken

If you're courageous enough, go take a walk outside today, or this evening, and see if you can reproduce.
Temperature a freakin' cold enough for it to happen these days! lol

Also, it's been discussed that most people think that SanDisk Extreme III is the SD card for extreme temperatures.
Which brand? is it?

Lexar 16Gb ... class 6
But like I said, this exact same card used to be in my GS1 and never encountered this issue back then.

Re: External SD vs. cold temperatures
I had an issue last week where, when I was outside on a job site, my sd card became corrupted. Lost everything on it and the card was damaged so badly I couldn't even reformat it to get it working. Had to get a new card. Don't know if it was coincidental or not. It was only about -4 C.

Mine got corrupted as well the first time as I didn't expect this to happen.
I kept trying to access it up to a point where when it was available again it got corrupted.
Had to format it and lost everything.
Since then, when this happens, I let the phone sit for a while and never had data corruption since.
Still curious to know if this is phone or memory related...

It was indeed the external SD card that seemed to be the problem. Switched temporarily to a 16Gb SD from my old GS1 i9000m and couldn't reproduce. Have bought a Sandisk Ultra 64Gb Class 10 micro SD card since then and couldn't reproduce with it either.
Glad it's not the phone! :victory:

Micro SD Card Questions

I recently pre-ordered the Sony Xperia Z2 which only comes in 16gb so I am forced to get extra storage, but I have a few question regarding micro SD cards. While reading my post please keep in mind I am still a noob. :angel:
1) Is 32gb enough or is it recommended to get 64gb? I will probably watch movies and TV shows but will not be putting music on the phone since I am not a fan for personal reasons. I have also heard that bigger SD cards can slow your phone down and some people tend to have problems with them, is this true?
2) What brand shall I get? SanDisk or Samsung? I have read that even though two micro SD cards are the same size and same class there is still a difference due to the brands.
3) Apart from the storage size and the class of the card is there anything else I should be looking out for?
Thanks

Hm....the xperia z2......it has up to 128 gb memory expansion according to gsm arena. If you want to save movies and tv shows to your phone, I suggest you buy a 64 gb memory stick, so you can save more stuff. As for the brand, there's no actual difference to me, and as for the bigger size that makes the phone slower, that's not true, unless you have your memory stick full of stuff like music, videos/movies/tv shows, images and such stuff (note that I have mine with such stuff loaded and I have no problems). Apart from the storage size and the card class, no, I think you're going to be alright. Hope I helped...

if you are a Movie TV fans,i suggest you add a 64gb extra storage,then u could smoothly enjoy the show and u can save more tv show you like

I agree, i fill up a 32 gb like its nothing. and thats just pictures and videos. if you use instagram it fills up allot faster.

Alright, I'll go for the 64gb one and Samsung seems like the reasonable choice to make.

suggest you to get a 64GB extra storage.
and maybe kingston is ok.

We can't really answer that. If you don't re-encode movies you'll likely quickly fill up 32GB. On the other hand, bigger cards get cheaper, faster and more reliable (ok, not always) over time. I'd decide by price, you can always easily replace it later.

go for sandisk ....class 10 ultra ...64 gb . actually you have video recording @ [email protected] will going to take more speed as well as memory than expected .

i have got Samsung micro SD class 10 48mb/s 32 gb huhuhuh! it's cool and works fine!

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 did not know that it is possible to tell the Spotify app to use external storage. Will try when I get my new card.

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.

Actually, if Spotify recognises your sd card as removable storage, it even is the default setting

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.
