I have 3 micro SD cards, the 4GB that came with the Desire, an 8GB which came with my Touch HD and a 6GB which I bought for my old Vario III. Will the speed of these cards make much difference to the running of the Desire, especially with apps on the SD card. Also is IO performance more important that transfer rates?
Would like to put a higher capacity card in the phone but not if it'll slow things down.
Done some quick testing of the various cards and the 4GB card that comes with the Desire is a lot slower than the other two cards. Seems the 8GB is actually the fastest at transfer speeds and has the highest IOps so I'll swap it over for that one.
Ok, well I transferred all the stuff to the other SD card and now my phone doesn't recognise any of the installed apps. Is it not as easy as transferring the files between the 2 cards?
Check The SD Class WQritten On THe Card
My 4 GB is lot faster then another 8 GB i am using
Now here's a question for all of you:
What is the MicroSD Card that is included with your phone? I know it's a 16GB, but does yours have a company branded on it, and also what class is your SD card?
The reason I ask this is because I want to know if they switched the SD Card on my phone with a crappy one and took the good one just before I picked it up. The SD card that came with my phone is just a plain generic Class 2 card. CLASS 2!! It doesn't even have where it is made at. I'm thinking, are you serious?!?! The transfer rate is so horrible, averaging only at 1.5MBps. Takes me over 30 minutes to transfer about one 1GB of files.
My friend who got the rezound at least got a Class 4 card, even though it's generic and made in Taiwan. But his transfer rate is averaging at 15MBps.
So I just wanna double check with all of you and make sure we all have the same type of SD card.
p.s. Also, this could be the reason why the phone sometimes perform sluggishly. I have a feeling when it pulls anything from the SD Card, may it be a large app, music or videos etc, it will have to wait to read from it.
OH! could this be the MAIN reason behind the slow response when taking pictures? I read that this phone has a horrible camera speed, but it might be due to the SD Card being slow and can only write at very low speed to the card.
I also noticed the slow performance of the included micro sd card, and I can't even access it from my card reader, but only through the phone's "mass storage" mode. Anyway just ordered a Sandisk class 4 32GB card from amazon...
The default card that came with mine is a Class 4 8GB made by Kingston. It doesn't say Kingston on it, but I have an actual Kingston SD card to compare it to.

If that's the default save spot, then yes, that could possibly be the issue. How big are the pictures?

8GB class 4?? wow that is small in size, although it is a class 4 card. Livid, is it because you are on Bell? Could this be carrier related? Also, how is your camera? Is it having that speed issue in between pictures?

bmxant, I took some pics and at full res, they average at around 1.3-1.5 MB, which is just right there with the speed, giving it a second or 2 delay in storing/saving them onto the sd card.
Sandisk Class4 16gb in mine. Mine was ordered and sent directly from AT&T site...I'm leaning toward them swapping out the card on yours.
If you're only writing at 1.5Mb's, that would definitely cause an extra second of lag. Would be nice if we could see a comparison between the Class 2 SD card vs Class 4.
How much cheaper could they get? It's bad enough the phone has 4GB of internal storage. They should of included either a 32GB Class 2, or 16GB Class 4.
Edit: Just read Namuna's post. Why would they swap out the card?

Alright thanks, I just need some more confirmations and I can visit the store again and confront them with it. I will make them open a fresh box in front of me and check it, unless of course they've swapped all in that store lol!
@aquariuz23: It probably is carrier related. You guys got double on the SD storage and RAM storage versus what we got. I feel a little screwed in that regard, but meh.
For photo taking, it only took one second to snap the picture and store it on the card. The gallery took 5 seconds to read 84 pictures that were stored on the SD card.

That sounds pretty good, what does Antutu say your write speed is?
Topram Class6 16GB here. SD Tools report 18.5MB/sec read and 5.5MB/sec write, which is pretty accurate for C6. (btw, card manufactured in 2009)
This phone I bought used, can't confirm the card is the original.
6.3 MB/s write and 13 MB/s read. It's about average for a Class 4 SD card.
what do u guys use to test the read/writes of the sd card? I wanna do a test on mine as well.

I always used Antutu
Tested with SD Tools
http://www.amazon.com/KOMPUTERBAY-C...&s=electronics&ie=UTF8&qid=1325197909&sr=1-11
Think this is worth it?
I am getting an average of 2.9MB/s Write and 11.1MB/s Read. Seems like a typical class 2 card. Took it a while to run the test too since it's so slow lol.
I got 5.4MB/s write, 15.5MB/s read (Antutu) on the 16GB Class 2 card from my Captivate that I wiped and stuck in the Nitro and gave the one that came with it to my Captivate (running hacksung's ICS). Is the included card that bad?
According to AnTuTu:
3.4 MB/s write
>50 MB/s read
According to SD Tools:
5.7 MB/s write
20 MB read
Nothing like some consistency between utils.

That just crippled my trust in AnTuTu's tests...sorry but there is no microSD card with >50mb/sec read speed, it's impossible.
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.
I have tried two SD card in my phone now.
They work fine when not in use but if I write to the card the performance is abysmal.
The cards were Samsung 64GB UHS1 class 3 100MB/s. (Not slow cards).
When I write to the SD card from the phone or my external nas or a download. The homescreen performance is unbelievably laggy. When it stops it's fine. No apps are stored to the SD card either.
When I put the cards in my PC. They will write at 50MB/s all day long, in my phone they hit about 20MB/s for a small period then drop to 5-6MB/s.
When I run A1 SD Card benchmark my write speed for my SD Card was 8MB/s. On my PC it's much faster.
Can anyone try something similar? Download a 500MB file that saves directly to their SD Card. Even if I download an album directly to SD from spotify I get lag on the homescreen.
did the sd card benchmark, the top one, that matched the size of my card in a1
my results are 75.69mb read and 59.76 write on my s9, card pulled from my s7 and plopped in the new phone as is.
64g samsung pro plus
let me know about specific testing, new to the app, but already had it installed.

Those are very slow cards actually.
Ive been using these, the difference is staggering.

That said your home screen shouldn't be lagging like that, got to be something else going on.

So I just left it and it's okay now. Maybe it was doing something in the background. Managing 50MB/s writes and not lags on the homescreen, not sure what was going on!
Is there a large speed differance between internal and SD memory ... loading programs and data ?
Yes, huge. View attachment 4698499

I have similar speeds, for the internal card.
With a 400gb SanDisk Ultra UHS-I card "up to 100MB/s" read SPEED I have a write speed that's slower, ~ 15 MB/s. Read was 80MB/s. I guess getting 80 MB/s is "up to 100MB/s"
For the fun of it, I tried my USB-C memory stick and got 73MB/s read and 15 MB/s write.
I have video on my external card, and have not had any read issues.

Yea, my external microsd card is of the same lineage as yours, I bought the 200g a1 UHS-1 card and on my PC I was getting 87mbs and 40 something mbs read/write using Crystaldiskmark which is consistent with what I'm getting using the Android benchmark app. You're write speed should be higher than that. I just had an issue with an old "Ultra" card and the write sped dropped to under 10mbs. I logged onto Sandisk and they agreed that it was bad and are sending me a new one. If I were you I would use Crystaldiskmark v6 and run some tests on your PC and screen capture the results. If you continue to get write speeds like that I'd create a ticked on the Sandisk site and see if they will replace it.
Thanks for the suggestion. SanDisk is good about warranties. I had a USB Dual Micro 128gb stick they replaced when it fell apart. Recently it faulted write protect only, and they offered to replace it again, but I can't wipe it because it is read only, and it has tax return data on the stick. It's only $35ish bucks, so I'm not sure I'll send it for replacement. I was thinking later this year of upgrading from 400gb to 512gb, I may wait until then.
so If I want to get serious about running linux on the s4 I probably should upgrade to a 256gb
model
The higher-speed reads are from a "cached read" which says more about the cache speed than the internal flash speed. In Android parlance, the "Internal SD Card" is the storage partition of the internal flash, which is slower, because it's reading the flash speed, not the cache speed. The physical SD card will be listed as "External SD Card", you would need to read that, not cached, to see how they compare. There are many microSD cards available with higher speeds than the internal storage in the screenshot, so if the SD card reader on the phone can keep up with them, external SD cards may be faster at sequential reads and writes.
It isn't shown in the screenshot, but random reads and writes mater more under some use cases. The SD card will likely have much lower random read and write speed, because of the extra latency in the SD card interface.
In the screen capture, the card I have circled as the Sandisk Ultra is in fact a physical card inserted in the Tab, why on that particular benchmark is says "internal" is unknown. The Sandisk card, while not the fastest isn't bad on read for an SD card as it reads close to 100mbs when tested on my PC but is nowhere near as fast as the real internal memory, cached or not.
