Hi guys,
What is the fastest memory card speed G6 (not plus/play) can use? Somewhere I read Motorola recommends U1 or faster. Is it worth investing in a fast card?
E.g. a Sandisk 32GB 100/90 MB/s is the same price as a Samsung 64GB 100/60 MB/s so if the phone couldn't use the fastest speed anyway, I'd rather take larger capacity.
I'm planning to put apps on the card. My old phone has slowed down considerably when I did that, so if the G6 CAN use the faster speed, I'd prefer that.
Thanks!
Sandisk 160/60 card gets 77/44 on moto g6. The same card gets higher speed on a lower end phone. Apps run okay at that speed on g6 but don't know if consistent use for apps lowers overall performance. Other users should post their speeds so we can get an idea what's the max speed g6 can get out of microsd cards.
Actualy in the meantime I bought the Sandisk Extreme Plus A1/V30 (95/90 MB/s), I just haven't installed it in the phone yet.
@e4noob what app did you use for benchmarking?

I used androbench. Please post the speeds on this card. I'll predict around 80/50. I have this suspicion that g6's card reader might be low quality. But it would be nice to be proven wrong on that.

Okay I put the card in the phone and ran 4 tests with Androbench. The *best* results, rounded up to 5/50 from each category are:
Squential read/write: 80/65 MB/s
Random r/w: 4200/1400 IOPS
SQL Insert/Update/Delete: 950/1200/1900 QPS
This is a brand new Sandisk Extreme Plus 32GB card (95/90 MB/s) formatted as external storage.
Also ran 2 tests on internal storage (note this phone has been in use for 2 weeks and it's half full so there's certainly some data fragmentation):
Squential read/write: 260/100 MB/s
Random r/w: 11600/5300 IOPS
SQL Insert/Update/Delete: 1100/1200/1550 QPS
Not sure what to think of the SQL numbers but in the random r/w performance the internal memory trashes the memory card so it's probably not the best for running apps. Sequential write is quite close though so I guess Sandisk's claim of 4k video recording holds true.
Hm, I wonder if there are memory cards meant for faster random access (like an SSD) and would phones be able to take advantage of such speed?
Edit: fixed my mistake about what card I have. It's a Extreme Plus 95/90, not Pro.
~ never mind, a rant was here how I can't format the card as internal storage but I found it. Good.
After formatting as internal, the phone complained the card is slow.
I let it move 4.5 GB of data from internal memory to the card, which the phone said would take 7 minutes. It was done in about a minute.

I've seen that too (phone warning the card is too slow) when I was experimenting with internal storage format. If you face any issues like phone wigging out or apps going missing or card crashing, let us know here.

No problems so far!
On my last phone with a basic Class 10 Kingston card, I had problems with apps disappearing after a reboot. It was especially annoying with Amazon Kindle which was the biggest (movable) app and I had to keep it in the phone memory.
No problems with the Moto. I even enabled the developer option to force apps which don't support it onto the card and they all work fine. Which is super cool especially for navigation apps with their massive offline maps. Neither Sygic nor HERE We Go support moving the app onto the card. (In both cases you can move the maps onto the card but only if it's formatted as external storage, not internal.)
Apps start really fast. I *think* I can sense some slowdown when running some apps like Duolingo and LingoDeer compared to when running from internal memory, but it might as well be my imagination. I see no slowdown when running Waze which is a lot larger. And the phone is slightly slower to boot but that's no biggie. It wasn't fast to begin with. But all the card apps are available IMMEDIATELLY upon booting, while on my old phone/card it took another minute to initialize.
Last night I noticed the phone tends to kill background apps way too aggressively, which is bloody annoying but I doubt that has anything to do with the card, it's more like another stupid Android/Motorola feature. (I have the adaptive battery feature disabled.)
Another odd thing is that the storage reports 5 gigs of games in the internal memory even when I moved all games onto the card, so that's clearly another Android bug.
So yea, I think it was worth it investing a little more in a faster card. I wish the phone would be faster overall but for what it is it's fine and the card isn't slowing it down so far.

Hi all,
I have a SDHC 8gb (Class 4). I tested its speed with J-benchmark. Frequent test shows that the write speed of this SD isn't any better than class 2 sd card i used before(4 gb).
I usually get write speed of 1.5mb/s and read speed of 2.5mb/s. Today I decided to change the buffer size to 8kb and got 4mb/s write speed. This is what a class 4 card should normally hit right?
So, I'd like to know if there's any way i can increase the buffer speed while transfering files from my PC. I'm really having a hard time copying movie files to my sd card. Files transfer of larger than 100mb take ages and even get disrupted at times.
Thanks for the help!!!

Random no-name brand? No surprise.. Lots of cheap, slow, unstable storage cards out there these days.
J-Benchmark isn't of much use if you don't know what the real workd transfer speed is, so you might want to try testing it against the computer... Send a large file, time it, see how long before you can safely remove the device.

well, it says transcend but i'm doubtful. Bought it at very cheap price from a wholesale market.
But there's something I've noticed, the transfer speed is slow through usb only...if i unmount the card and use it through a normal card reader its quite fast...I tried sending a 800mb movie file and it took just above 4 mins....
So, I don't think its the card that's the culprit. puzzled!!! could it be the rom i'm using or froyo itself?
I'm sorry that I can't be of any help, but i got the exact same problem. Bought a 16gb card, kingston brand, class4 (don't expect that much of it, but the stock was class 2, so i figured that it would be ok..)
I get horrible write speed, around 200-250 kb/s (or whatever it's called). Don't remember what the old one did, but it wasn't that bad.
I've plugged the card directly into the PC, and it gets much higher speeds..
Exactly the same problem, as u guys..
Come on, an hour to copy a movie to the phone, that's just not acceptable!
PS: have you tried this?
Mine was allready at 128, but it's probably worth a shot..

Hope anyone has some solutions to this, it's just seriously annoying
Oh, and i've got the desire with cm7 on it, it's not that different from the n1..
It's the phone not the cards. It just doesn't appear able to acheive transfer speeds higher than you'd get with a Class 2 SD card.
In the link i posted, there was a guy who found out a way around the limits of android on a EVO 4g device. I was hoping for a similar fix.. Or just something
Bought a Class 10 Kingmax and disappointed that write speeds are still maxing at 1.5 MBps Waste of money
2.5Mbps in recovery.
SOOOOOO SLOW copying videos over yaaawn.
Using a card reader means switching off the phone, which is not really an option IMHO.
You can benefit from the faster rated cards if you use a card reader, and even better if you buy a second card so that you can load up one while using the other. Quick swap, job done!
I have a Transcent 8GB class 6. I get speeds from 6mb/s-8mb/s.
I have set up the CM7 on an SD boot and it works for the most part.
However it seems very unstable, about 3/10 uses it will crash apps. I really only have Aldiko and the Nook App on it and maybe Angry Birds and a Task Killer.
Aldiko and Nook etc will just go into an error loop saying the app stopped unexpectedly and then I have to hold the power button to shut it down.
My question is if this is typical of using the SD root method?
Then, if I do a full hardware root/ROM is it generally more stable in your experiences?
I suspect that part of my problems are the SD card itself, I had a 4GB Class 2 Sandisk card initially and it worked well but it was very very slow. So I got a Transcend brand 8GB Class 6 card which should work, it is a big name brand and all, and is much faster but CM7 seems very unstable. Is it all just the card?
Yes, your card is the culprit. So far from people reporting here you need a SanDisk Class 4 card. Its all about the 4k read/write speeds of the card you're using. You want a 1.0+ in CrystalDiskMark to get decent performace and get rid of the FC's. I am using the card I linked here and have not had any problems running apps or the Nook freezing.

I had similar problems (sometimes intermittently) using an A-data card, I think it was 8GB class 6. I finally installed to emmc and have not had any problems since. The CM7 nightlies go to the point of being so good that I never needed to boot into stock anymore anyway.
So if I get it working on the SD, is it even worth doing the perm internal ROM mod?
Or is the SD MOD just as good/better?

Running off the SD is so good I haven't even felt like trying to put it on the internal memory. The only thing you lose by running it from the SD card is the ability to pop out the SD card whenever you want, though the only times I've popped out the SD card is to put the newest nightly on the boot partition. And thats just cause I've been too lazy to figure out the exact mount commands to mount it on the nook. If I want to get/put files off/on the SD card I just plug it into my computer.

Internal is always more stable.

I didn't run any benchmarks when I had it on a SD card (16 GB SanDisk class 4) but it seemed about as good as it has been after switching to eMMC.
The CM7 SD card mounts internal memory on mmcblk0 and uses it... (I presume for caching, etc) Speed of the SD shouldn't cause crashes. Slowness yes, but crashes?
Re: SD vs. eMMC, an SD install can be just as fast and stable as eMMC, but SD installs also seem somewhat prone to suddenly and mysteriously losing that stability, developing FCs, WiFi issues, lag and even freezes/crashes. There are also more robust and straightforward tools for managing eMMC installs; both CWM and ROM Manager tend to have quirky interactions with SD installs, performing some operations on the SD partitions and others on the internal partitions. I would advise anyone who finds that their SD install has become their sole or primary OS to eventually move it to eMMC. Even if you're still using stock quite a bit, an eMMC dual boot (see my sig link) has advantages over running one system from SD--mainly, that the two OSes can both use the SD for storage.

See this thread: http://forum.xda-developers.com/showthread.php?p=12964262
There's no such thing as "Speed of the SD." There are several metrics, primarily large sequential vs. small random reads and writes. Card class (what most people assume equates to "speed") is based on the former, whereas performance as a boot drive correlates with the latter. A card optimized for large writes tends to suffer badly in small-block random r/w. There's no such thing, presently, as a card optimized for small-block r/w, but SanDisk class 2, 4, and unclassed cards tend to have very balanced benchmarks, with reasonable performance across all metrics. This places their small-block r/w speeds 10x and 100x ahead of a card optimized to meet class requirements.
I've also been hearing there's an issue with some cards reporting their reads and writes using an oddball protocol that's currently unsupported in the kernel.
I know it has been asked a lot in the past, but searching didn't provide Milestone specific answer.
So If I buy Class 6 or Class 10, will the milestone be able to utilize the full write speed? I am running Cyanogenmod 7 RC0 (latest). At the moment I have 8GB class 4 Apacer microSD and tbh its a terrible card. All I get is 2.5 mb/s write on large files, but I am getting the same speed when the card is in card reader too so its not phone issue.
Thanks.
Maybe I'm wrong, but what I know is that the card class is the limit. It doesn't mean it will read/write at full speed all the time.
How are you testing your speeds?
Maybe SD Speed Increase help you.
https://play.google.com/store/apps/...t=W251bGwsMSwxLDEsImNvbS5zZGluY3JlYXNlLml0Il0.
I don't know how to test my speeds, but were getting 24mb/s read and 8mb/s write speeds in SD Tools ( https://play.google.com/store/apps/...1bGwsMSwxLDEsImFsZXMudmVsdXNjZWsuc2R0b29scyJd ). I'm using a Samsung 16gb Class2. I think the app is not calculating very well. Don't know.
I am using the SD card as USB mass storage instead of carrying separate thumb drive. I transfer a lot of large 1+ GB files.
I tried SD Speed increase last week and it does make a difference on smaller files, but when copying 2GB files it seems to start fast (like a burst mode), but if timed it takes exactly the same time to write something on the card.
I am going to change my 8GB card for 16GB today anyway I just wondered if class 10 is worth getting or should I get class 6 and save some money. Whatever I buy I will report back and test the speed.
I went ahead and bought Patriot LX 16 GB class 10 microSD. Now I get variable speeds from 3.5 mb/s to 8 mb/s depending on the file sizes. As I read somewhere this is due to fact that the phone is using MTP protocol to act as mass storage device.
Anyway with the old card I was topping only 2.5 mb/s no matter the file size, so it's definitely an upgrade and since class 6 was only 5$ cheaper I saw no reason not to buy the faster one, even if the milestone can't utilize its full capability. In the end its an old phone and I believe there weren't any class 10 cards out in 2009 anyway.
And one more thing, the camcorder isnt lagging anymore when recording videos
EDIT: After booting in recovery and clearing dalvik and cache partition I am getting 9.5 + mb/s, but it does start around 4.5 mb/s and then rises to its full speed. Cheers.
Except for the improvements in video recording, is there anything else that runs smoother for you when using the phone?

I think everytime any app need to access your sd, it will be smoother, like gallery, taking photos, loading maps cached in sd, music apps indexing songs, etc. Accessing apps installed on sd card may be loaded faster too.

Thats right. Gallery loads faster, applications and games moved to SD start up faster etc. Don't know about maps, but I suppose they cache faster too.
However the main difference is when copying stuff to phone in mass storage mode. Thats why I got a higher class card in first place. While all other stuff related to reading from SD do seem snappier, the difference is not all that great since even Class 2 cards can read with high speed, but when it comes to apps that are writing the difference is obvious.
I'm using a Samsung Essentials 32GB Class 10 Card.
Gave me some troubles at first, something with sector sizes seemed wrong - but after formatting it with this tool https://www.sdcard.org/downloads/formatter_3/ it worked.
Someone in these forums suggested the tools - search for the link to find the recommended settings.
Alright, thx for the answer. For someone not using the phone the same way as you, do you think it would be worth the money to get a faster card?

The difference between class 6 and class 10 right now is only few bucks. I don't see why not. You never know, may come in handy.
Here check this out, less then 1$ difference in price.
16GB microSDHC CARD Class 6 - Transcend
16GB microSDHC CARD Class 10 - Transcend
I wouldn't go below class 6 since the camera is lagging when recording videos.
Is it true that if a formatted microSD often will make it slow microSD?
It' unlikely, but possible.
My Samsung Essentials 32GB Class 10 card gave my Milestone hiccups at first (rebooted several times when powering on, rebooted every time I left USB mass storage mode) so I re-formatted it using these instructions: http://forum.xda-developers.com/showpost.php?p=23494134&postcount=7417
Now everything works fine and I still get a little more than 10MB/s when copying movies via USB - so no loss here.
Has anyone tried the 'adaptable' storage hack on the Note 8 yet?
Worked on my S7.
I have the same question
I was thinking about doing this but from what I hear it's more trouble than it's worth but if anyone whose done it would like to chime in I'm sure we'd all greatly appreciate it.

I feel the same way. More trouble than its worth. The 64GB is plenty for all your apps and for everything else you have your fat Micro SD card.
I can't find half a reason to bother with it. 1. Many apps, especially larger one will use SD card for storage, if not you can set it to do so in settings. 2. SD card is slower than internal memory, so frequently used programs shouldn't be there 3. It creates whole lot of problems if SD card goes bad and yes, had this happen to me multiple times on Sandisk included. 4. it can get complicated when you swap the cards between phones, computers etc and you use the phone without dedicated SD card inside 5. If you really think 64GB internal storage doesn't do it, hunt for elusive 128 and 256 GB versions. They should show up somewhere.
The only a reason to do it I can think off: "because I can?"
I wouldn't do it unless the UFS ever comes out. Supposed to be a lot faster external storage.

Note:
- You will need TWRP installed.
- It might not work for you. I've only tested it with Renovate.
- You will need to use adb to set up your sd card.
You won't do it on an unrooted phone. Samsung never implemented it.
The phone's built in memory is far faster than any SD card at this point. You'd be slowing your phone down... and not by just a little bit.
I beg to differ
Agree the phones internal memory is tops right now.
Disagree the phone will be slow if you offload storage.
Source: i have virtually every app i use daily (Save a couple) moved to SD card and ive noticed NO.. I repeat NO.. noticeable difference in speed or issue by moving these apps. And im talking about WhatsApp, textra, several video playing apps, Instagram, Snapchat, outlook mobile, and some other apps.
There is SOME residual data from these apps that LIVE on the internal storage—perhaps this left over data keeps the app from bottlenecking from the SD card. This is speculation though.
If interested, in mexico, the largest carrier, telcel offers the 128 Gb model
Hi - I got a Toshiba exceria 128gb micro sd card. Didn't really look when ordered, but turns out this is a UHS class 3 card - apparently the fastest class currently produced in terms of minimum read/write speads.
My phone recognises the card, asks for external/internal use - then says it 'too slow' irrespective of external or internal formatting.
If formatted as internal, the phone then get stuck in a bootloop when shutdown or rebooted - it will constantly go to fastboot/recovery. Occasionally, after going to fastboot 4-5 times it will reboot normally to system.
The only way to get it boot consistently is to pop out the sd card, then pop it back in once the phone is booted up and asks for the missing card. Then it runs fine - although I feel apps installed to the sd card run slowly.
Needless to say, this a PITA - my current solution is just to leave the phone on and put it in airplane mode overnight.
I can find mentions of similar issues on the other G5 series phones, and even the G4 - all those threads seem to indicate the these phones will only handle cards up to UHS class 1 correctly.
Before forking out for a UHS class 1 card, is anyone else experiencing this issue?
Cheers!
PS - Note the phone is stock with the october 1st patch level. I've tried wiping cache and/or doing a full factory reset via stock recovery, but the issue always comes back.
I got a super fast card like that (it was a Samsung 64GB though....from what I could tell by Amazon reviews, they make the most reliable fast flash memory), also formatted it as internal, and have had exactly zero issues in a month of heavy usage. So I'd say it's your card.
P.S. Are you in India or something? Because I have yet to see a single update past June.
No problem with mine, Samsung Evo Plus 128GB. Well, it says UHS1 card on the cardboard but have u3 logo on the card. I suspect it is the same with exceria
It also gave me notification that it is slow. Seriously, something is wrong with motorola, the speed is slower compared using it on PC.
Just an advice, don't use it as internal. There is no real advantage of internal except installing app on sd. It is a time bomb because it isn't robust enough to handle read/write for a long time. When the time comes, it becomes corrupted and you pretty much have to deal with what you had through and probably lose most of your data as well.
Do you know why Google never put sdcard support in their devices since nexus era? IMHO, that is one of the reason. It isn't as reliable and as fast compared to the one they use as internal storage. Well, of course nowadays, they are doing it mostly for gaining money by people using cloud storage.
