Using fast SD cards?

I see these 66x superfast SD memory cards advertised. Will using one speed up my blue angel?
Can programs use this SD card for operating memory or can they only use the intenal memory?
Does having <5mb avaialable slow down your device?

Fast Sd Cards
Fast Sd cards are only useful for SLR Pro cameras. The rest of the devices are using normal card reader slots. i.e. even if you were to use a fast SD card in the sd card slot,you will only get the normal speed.
by rest of the devices, i mean, all pocket pcs, ppc phones, phones and such devices...... :x

moali77 is correct. it won't make much of a difference in your pda. however, if you use a card reader, or happen to have a digicam that can utilize the speed, you will be better off.
example: i played atlantis redux recently 100mb+ required to be put on your sd card. instead of copying it through activesync, i put it in my usb2.0 card reader, copied it over, in far less time than it would've taken if i did it the other way.
but if you don't plan for much of that, then don't bother paying the premium for a fast card =)

Well I bought a Kingston Elite Pro Secure Digital 1GB, think It's 7.7/8.2MB Write/read
It made my TomTom go way faster planning routes and generally give me better performance from other apps.
I dont know the Top speed for the BA SD Slot, but you should look at the speeds of the card you are planning to buy

Have others experienced similar variations with different SDs?

I recently responded to Wamatt's other posting about SD cards in the BA accessories forum. In it, I've described my experiences with the SD card listed in my sig and BA speed tests I've done with it.

Find a good ExtSdCard?

Hello,
I've use the good mod created by mattiadj (http://forum.xda-developers.com/showthread.php?t=1772234) and it's mean work!
I've so actually some games into my Extsdcard (that my phone see as internalcard), but this games have sometimes some lags.
I think it's because the games are installed into the extsdcard. I've right?
In this case, it's maybe because my Extsdcard is a "simple" card, not a samsung card?
If i change my Extcard, this lags will be again present? If no, what Extsdcard (32go) can you advice me?
thanks, and sorry for my english.

Huh?

I need to explain?

So your afraid your games are lagging because you have a "cheap, subpar" micro sd card?
Possibly but doubtful...
If your games require a internet connection , could be a slow connection.
Btw horribly explained.

The way I understand it is that apps that's are on the external card are slower, no matter, what than ones on the internal card. So even though you have a sub par SD card moving to a higher quality probably wouldn't give you a noticeable difference, depending on the size and demands of the game.
If you did decide to get a better quality SD card then I would go with one of the sandisk cards as opposed to a Samsung SD card. Everyone has their own preference for SD card manufacturers but I've always stuck with sandisk and haven't had a problem.

Using External SD memory as internal

Hi Moto ppl, today I get a brand new Micro SD Class 10 of 64GB of sweet storage space, and I dunno what to do with it, wirth this I mean since Motorola knows better and don't force-close the option to use SD as internal memory like Sam**** or LG. I dunno if it's worth to use my new memory as Internal or just leave it as a regular external SD to my media files as usual.
On purpose I get the class 10 version to get faster transfer speed from which I look up it has around 45mb/s so it's not bad at all.
Reading a lot of this feature some ppl may say that is not fully-recommendable because the phone gets lag-down so it reduces his overall performance even when you use the faster SD you can get since it's not part of the main board of the phone.
Other ppl says that when you get a Class 10+, UHS, etc SD you will be fine.
I want to ask you guys if somebody already try this on your Moto Z Play I know I will get around 91GB of total space wich is a lot, but since I PLAY A LOT of games, leaving those 64GB to my gamepedia is really sweet. But I dunno If will be against having performance issues?
Regardless I will try it and post my first tests here over time.
Cheers!

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.

Adoptable Storage

Hi guys...
If i buy the 128gb model have Samsung finally allowed the use of an SD card as adoptable storage yet?
If not is their a hack to enable this for this phone?
thanks in advance

As far as I know adoptable storage was never fully implemented by Android. From what I understand the speed of the SD card is way slower then the internal storage so if you merge then together you end up with a weakest leak situation. Samsung's inclusion of adoptable storage is what made TouchWiz so darn laggy. For now it's still actually there but case by case. If you go to different app settings some will give you the option to move it to the SD card. And it's always be that way. Nothing new.

I am pretty sure adoptable storage on Android is a standard thing - since Android M.....its just Samsung that refused to implement it.
I do understand why they dont implement it - that's because if people use it the phone will lag and slow down sometimes when using apps whos data is stored on there - and samsung are worried they will get support calls regarding this and also it may reflect badly on the phone itself...
I currently own a razer phone 2 (RP1 previous to that), and previous to that all Samsung. The RP1 and 2 both support adoptable storage and as long as you purchase a high-speed sd card (not the standard ones) then adoptable storage works well
I want to buy the 512gb Ultra but they are out of stock everywher in the UK - so i thought an option would be to buy the 128gb as long as it supprts adoptable storage so i can "turn it into" a larger device storage

I know this an older thread, but with the speed of cards, I don't understand why an alternative to adoptable storage hasn't been developed. I had the Razer phone 2 with a Samsung EVO U10 512GB card and the phone was not noticbly slower in everyday tasks, but did slow when loading games and such. I still loved it, however, I think it was ditched by Samsung because people don't understand that once the card is adopted, removing it with the device on, renders all data on th card as corrupt, even upon reinsertion. Sometimes it's reclaim the card other times it wouldn't. Samsung tech support would be inundated with calls related to it so it was disabled. With the files sizes ballooning, 256GB should be the smallest storage available on a a premium phone and with the advances in storage, why isn't the OS determining what can and cannot go onto the SD card automatically?
I currently use APP2SD and while it moves the apps, I don't seem to be gaining that space back on the internal storage. Weird.

While not a strictly apples-to-apples comparison, I find fbind more flexible and largely superior to adoptable storage.

i will just wait until terabyte nand-flash ufs will be standard in even the cheapest smartphones. apps like firefox, aliexpress, amazon, google itself generate so much data it's horrible. i have to clear the data once every week. when you watch a movie with firefox for android and the movie is 1000 mb big, guess how much nand-flash will be used? you guessed correctly 1024 mb!

Adoptable storage is awesome - it works really well on all but Samsung.
Isnt there some way of using the external storage -
Its ridiculous that they build a tablet that has only 3GB storage free with a memory expansion slot that can hold memory but cannot be used by the system.
This device was a gift - will NEVER buy Samsung.
