I bought a SanDisk U3 SDcard for my SM-G965F. I attempted to ensure that it was not a fake by making sure that it actually had the claimed storage capacity, and that the speeds were in the vicinity of what it was rated for. Everything checked out fine.
However, in the phone, it's quite different. I used AndroBench to compare the internal storage and the SDcard. Here are the results:
AndroBench:
Internal Storage:
Sequential Read: 804.58 MB/s
Sequential Write: 193.8 MB/s
Random Read: 135.4 MB/s, 34663.32 IOPS (4KB)

SDcard:

Sequential Write: 47.73 MB/s
Random Read: 5.75 MB/s, 1472.04 IOPS (4KB)
Random Write: 2.51 MB/s, 643.61 IOPS (4KB)
SQLite Insert: 1111.91 QPS, 1.83 sec
SQLite Update: 2160.5 QPS, 0.94 sec
SQLite Delete: 2185.27 QPS, 0.94 sec
The SQLite benchmarks are similar, but the raw benchmarks are drastically different. When the benchmark runs on the internal storage, it seems to run each test smoothly and quickly. However, when it runs on the SDcard, it's jerky - it runs quickly, then pauses for a second, then runs some more quickly, then pauses for a moment, etc....
This can't be normal, can it? Does anyone have any idea why the performance is so much worse for the SDcard then it should be?

Looks about right to me, SD cards are a lot slower unless you splash out on a really expensive one. Shouldn't be an issue, I'd just save music, photos and videos on there and use the phone storage for apps

That's just it - I did splurge. My card was U3 rated, which means it was suitable for apps, not just general storage. It's rated for 160 MB/s Read, and 90 MB/s write. So it's not going to be as fast as the internal storage, but it's benchmarking at 50% of what I would expect.

Maybe it is a limitation of the phone, mine was also u3 but rated at 100 & 60 mb/s respectively

It's a comfort to know it's not just me, then. Thanks for letting me know.
As I know these card spec are max performance tested under certain condition that boost their capabilities. Still faster than U1 though. But much much slower than internal.
Close to claimed benchmark is on pc or laptop system, not android.

Here is a thread that seems to be making the rounds throughout the forums...

Following the guidelines in the thread, here are my results with CM7 using a Kingston 8GB Class 6 card...
Before:
Write - 6.6 MB/s
Read - 15.2 MB/s
After:
Write - 5.8 MB/s
Read - 94.4 MB/s
I would recommend playing with the values to see what works best for your particular SD card... Not quite sure
if it is a placebo type effect, but apps like the Gallery and games that use the SD card are noticeably faster...
Have fun...
I did extensive testing on a patriot class 10 8gb card today.
I had lowest standard deviation on results using 1024 buffer. I also had the highest reads at that buffer with a higher write speed.
I had the highest write speed at 4096, but the read speeds were slower than 1024.
I rebooted several times to make sure that wasn't playing into it, and reran many test. All results were relatively consistent.
~11.6 write
~86 read
@1024
~11.9 write
~79.4 read
@4096
~10.8 write
~71.9 read
@128
The change wasn't huge for me. Most have reported 2048 as the best setting.
Also, I updated my cm7_mod to include this. Working on making it installable w/ the scripting...

It's only meant to be used with cm7_tablet_tweaks as a base now.
Couldn't such a buffer size setting be usefull for emmc (internal memory) too ?
I'm using dalingrin's OC kernel with the IO issue, and it feels slower than my SD card...
I've commited this tweak already today. I would be interested to find the optimal value for mmcblk0.

Instructions for tweaking the emmc are in that thread. I wouldn't mind taking the time to test and crunch the numbers but sd tools only wants to test my SD card.
EDIT:
App called J Disk Benchmark 2.0 can test internal memory. Working on testing now.
Uhm... my SD card tests faster...
I hope people don't go over board and incorporate this type of permformance increases in their roms by default based on bench mark tools. there is value in increasing readahead for some access patterns, mainly when doing lots of sequencial reads. the trade off of course is at the expense of memory usage. nook even with its 500mb of memory is still not considered high in memory. setting the readahead to 2mb is quite aggressive and will work well in some work loads like galary when reading lots of files around 2mb in size while in other work loads it may actually have negative affects. I am not saying that this specific tweak is bad because I haven't done any tests myself, but don't always believe the numbers u see from benchmark tools.
I'm only setting it to 1024k. I feel like that is plenty high.

Yes 1024 is what I'm running really gave the best all around performance.
I think I found the internal memory and it's set to 128 by default
can't find any real difference between 64 and 4096. That looks like the only other mmc device though, so it must be it.

Yep, it's the same for me, my Class 6 SD card achieves 6,3/11,6 and the internal memory only 4,86/7,52...

Balls.
I'm going to jack it to 1024 and hope that works then.
OK, I can't get any meaningful numbers anymore. I think yesterday's test was a fluke. I can't get any real changes from 128 to 4096 (or in between) with fast or slow SD cards, big or small, black or dark black.
The write speed on slower cards is lower (5-6mb/s) and the faster cards are higher (10-12MB/s) and read speed for all is 80-90mb/s.
Maybe this is a performance mod not for us?
So, most of you probably noticed you have to have the Camera set to INTERNAL STORAGE in order for it to be even possible to shoot HD video as the external CLASS 4 SDHC card is incapable of writing fast enough. After searching all over the web I'm hearing about some successful upgrades to class 6 and even class 10 sdhc cards to fix this issue with mixed long-term results.
One of the issues I see popping up a lot with the class 10 cards is data corruption. Sometimes the data can be recovered with chkdsk, sometimes the card needs to be outright formatted to be useable again and all data is lost.
Does anyone know what causes that?
Is the Droid X2 even capable of taking advantage of the Class 10s speeds or is there an innate bottleneck that gives it speeds comparable to a good class 6?
Are certain cards performing better in the Motorola phones, such as this one?
I'm really interested in a 32GB card because the damn thing fills up quick when you shoot video, but I really don't want any headaches considering the cost of these things.
Has anyone with a Droid X2 upgraded to a 32GB Class 6 or 10 without any problems? Can you post benchmarks that show that the card is capable of writing at 10mb/s or faster?
I'll update this OP with any helpful feedback if it comes to that.
Please don't link me to any of the half of dozen other SDHC threads as it doesn't answer my question regarding the application, compatibility, and potential bottlenecks of Class 6 and 10 cards in a Motorola Droid X2.
I had a class 10 card, it gave me tons of errors. Sometimes just by plugging it directly into the computer would fix it. Twice that did not work and I needed a complete reformat.
I had my class 10 SD card in my Droid X2 for about 2 weeks before I needed a reformatting. But I'm a tech disaster zone, I think I ate a powerful magnet as a kid. But either way keep that number in mind. I got a quick replacement at walmart that didn't list the class, but it is working well now.
Oh and it was a 16gb card
Could you benchmark its write speed? If it's able to record 720 video without stuttering, all I need to know is how fast it's capable of writing data. Class 4s are apparently too slow, so it's probably a class 6.

Here's what I did. Removed old sdcard, installed new sdcard, powdered on phone, navigated to settings> sdcard & phone storage> unmount sdcard | format sdcard | mount sdcard.
Zero errors, it's been weeks since installation. Benchmarks 8.8MB read 13.7MB write.

i've got a 2yr old Kingston Class 6 8GB card that handles 720P video on this thing just fine. almost went for a class 10 but didn't feel the expense at the time was worth the minor speed boost. The handful of videos i still have are from a concert and going by size and length its writing around 1.5mb/s on average for mine. was a techno show, low light and lots of moving flashy lights.
Class 4's should be fine... but again i've rarely hit full speed with sd cards.
The Class 4 that it comes with isn't able to handle the HD video recording. View the resources section at the bottom of this post. There's also a youtube link to what kind of videos people are getting with class 4 SDHCs at the bottom of that list.
Could you bench your class 6 and post the results?
Here are two free apps that can do this easily for you:
An Tu Tu Benchmark
SD Tools
Thanks
SD Tools doesn't work on my X2 it says "Error reading buffer..."
I've tried to reinstall it as well with no luck. Anyone else having the same problem?
I just ran a test with AnTuTu, only I just realized there is only one spot for SD card speed. Did it just test my internal only? I also tried SD tools but it says "Read Buffer Error".
If it did test my external card then the Write was 5.2MB/s and Read was 8.2 MB/s. This card came from walmart, capacity 16gb, it was just what they had.
Ugh, stupid double post. Where's the dang post delete button? LOL

Oh wow antutu only benchmarks the internal. Personally, I benched mine from my PC. I didn't try the android apps myself. I just assumed they worked. Does anyone know a benchmarking app that works for the Droid X2 External SD CARD? I use ATTO from my PC. I get consistent 4.2 MB/s on the external but on the internal I cap at around 5.4. This leads me to believe that a class 6 card is more than sufficient, but I'm really interested in investing into a class 10 for the long term.
I haven't heard of anyone having problems with class 6s, so that seems to be a safe bet.
Anyone else out there with class 10s on their DX2 wanna post some feedback?
Edit: Benching program SD Card Speed Test. I have run the tests w/ a class 6 but I forgot where I placed the text files, but ican say there is a pretty decent difference.

Zero, and I've had this card for at least 2-3 weeks now. One thing I can say though is the portioning seems to slow it down significantly, not sure if it frees up much RAM doing it anyways with most of the apps going to the SD instead of the internal flash. But w/o bloat removal and the V6 supercharger I had 180 MB of RAM free at one time. I've pushed the old vold.fstab back, and I'll check out the differences in speed once again, along with total free memory.
Awesome. I'm gonna go ahead and list this as a known compatible. Let me know if any issues crop up, please.

I can see where hidef video recording would be important to have a fast sd card, but some are assuming the sd card is the issue for audio pops on the DX2. The problem with that theory is that MP3s cache a chunk or (depending on size) all of the file to memory and there are parity checks for audio continuity. MP3s do not stream from the card, per say. Even cheap CD players buffer at least a few hundred KB with cache and more for better players (to cover for driving environment).
I thought my SD card was causing my Mp3 files to stutter but after moving them over to internal memory it only helped a bit and stuttering continues.
This thing is a pos =p
I also can not find an app called "sd card speed test"... which one are you using zetsumeikuro?

Never had any of the stuttering issues w/ mp3 etc. If you think the phone is a PoS get rid of it .
Thanks blaq, but unfortunately that doesn't help much because motorola devices are supposedly fussy with some class 10 cards causing file system and corruptions and whatnot that other manufacturers' devices aren't experiencing.
As for music I have been using google music without any skipping issues and it's also freed up a few gigs on my SD card.

It's hard to know what's causing it but there is definitely a lot of freezes in the otherwise butters smooth animations. If I'm downloading torrent in the background, the device become unusable and applications (mainly the launcher) stop responding.
Every media take much to long to load,
I also suspect big movie files to suffer from that.
Transferring files on and from a computer is a pain and often the tablet simply stop responding.
In my opinion the storage speed is the bottleneck of the Prime performance wise. It s like using a computer with a slow ass HDD versus a one with a super fast SSD.
Of course i wish someone could re-run the bench on their tablet to confirm this.

I wonder if it's just that the internal SD card is slow, or if it's poorly optimized in software? I guess we'll find out once the bootloader tool is released.
My fingers are crossed for poor software optimization!
That write speed is just too low, I'll try the benchmark on my TP tonight.
When custom roms/mods etc. arrive we will have the chance to test it under ext4,JFS and other filesystems so i believe we'll see better performance
I remember seeing early reviews on the TF201 that the internal memory is unusually slow.
Why would Asus put such a high build quality on everything but the storage speed?
I have a feeling this is not hardware related but rather software related. There is no logical explanation why the flash memory inside our devices is so much slower than the common average.
What I want to know is how much bandwidth is available for the internal storage?
For example: I purchase a 64GB SSD drive that is meant for internal 2.5" storage drives. I hook it up externally and plug it into a powered ESATA port. The max read/write speeds of the SSD are around 300mb/s but the port's max read/write speeds are only around 200mb/s.
Did Asus make some unnecessary sacrifices to make the price of the Prime reasonable? I really hope not.
On a different note:
Copying files from Windows 7 to the Prime is immensely slow.
On Mac OS X 10.7.2 (Hackintosh) copying the same file is MUCH faster.

Well, I wanted to test Bonnie++ also on a USB stick on the ATP, but somehow it took insanely long, so I canceled that. I also suspect it to be a S/W problem, which gives hope for it to be fixed in an update.
I've not got my Prime with me to perform the tests, but having seen the results posted in here, I have to say that my SGS2 absolutely *smokes* the Prime in terms of I/O throughput. Very disappointing, I think that this thread needs to be brought to the attention of Asus.

I get the feeling they knew about this before launch.
hi ive got a genuine 32gb samsung class 10 micro sd that i ordered from play.com im doing some speed test and im only getting 13mb read and 11mb write speeds would it be because im using a old sd card reader?
thanks in advance
exfat as you can transfer files above 4gb if you are going to watch 720p movies or even 1080p movies. fat32 restricts you to only 4gb files. so yh exfat all the way. i think the siyah kernel can read ntfs, im not too sure. But yh exfat is the way to go.
Are you talking Mb (Megabit) or MB (Megabyte, 1MB = 8 Mb)
(The first letter is always in upper, since a lower-case m means milli which equals 0.001 instead of Mega which equals 1'000'000)
I'd guess MB: Class-10 cards have a minimum Write speed of 10 MB/s so you're still in the boundaries.
Also note that a card that has once been filled already is slower than a "virgin" card.
But of course old SD-card readers can make a difference.
I want to have a new micro SD card ready to go when I pick up my V30+ next week. There are some decent deals for 128GB cards at BestBuy and Amazon. I have tried searching for the info but haven't had any luck finding the maximum read and write speeds the LG V30's micro SD slot is capable of.
Samsung EVO Plus 128GB - BestBuy
Samsung EVO Select 128GB - Amazon
They are essentially the exact same card, just different branding due to when they were manufactured. Same specs and all but the EVO Select seems to be the newer of the two where the EVO Plus has been around since 2015. If the V30's micro SD card slot isn't capable of 100MB's read and 90MB's write, then I may as well go for something cheaper and slightly slower and save $7.
SanDisk Ultra Plus 128GB - BestBuy
Is anyone aware of what the maximum capabilities of the V30's micro SD slot is capable of? Is there a way to test this that someone wouldn't mind testing and posting their results?

Somebody did that a few weeks ago, I'll see if I can find the post.
EDIT
I was mistaken. It was the internal storage read/write speeds they tested.
V30 Internal storage speed?
https://forum.xda-developers.com/lg-v30/help/v30-internal-storage-speed-t3687990
They were trying to determine whether the LG V30/V30+ had UFS 2.0 or 2.1. It has UFS 2.1. (Earlier this year, Samsung shipped some S8 phones with both standards -- the Snapdragon S8 got 2.0 while the Exynos S8 got 2.1, while all chipset versions of the S8+ got 2.1.)
But several websites have done thorough reviews and have stated what's inside the V30/V30+, including exact components...

Other sites even give the manufacturer and component number:

This 6-inch display features a Quad-HD+ (1440 x 2880, 538 PPI) resolution 18:9 panel with nearly zero bezels all around, and is covered in Gorilla Glass 5. It’s also both Dolby Vision and HDR10 compliant. Inside is a Qualcomm Snapdragon 835 chipset with Adreno 540 GPU, 4GB of LPDDR4X ram and either 64GB or 128GB of Toshiba UFS 2.1 (THGAF4G9N4LBAIRB) internal storage, all with microSD card support for expandable storage.

As it’s pushing the same resolution screen as the G6 with a processor and GPU boost, it’s pretty obvious why the phone feels so blazing fast all the time. Combine this with Toshiba UFS 2.1 (THGAF4G9N4LBAIRB) storage and you’ll quickly understand that LG has outfitted the V30 with the highest end components available right now.

Even the Toshiba UFS 2.1 storage inside is a perfect match for Samsung’s best UFS 2.1 storage, which is used in most flagships now, and averages out just as fast as those chips. See the results of the benchmark suite we run for each phone, including 3DMark Slingshot, GeekBench 4, AnTuTu V6 and Futuremark’s PCMark internal storage test.

Under the hood, the V30 is powered by Qualcomm's Snapdragon 835, with LG using a heatpipe to assist in cooling. This is paired with 4 GB of LPDDR4X, and either 64GB or 128GB of UFS 2.1 storage.

Just used the A1 SD card speed test app. LG V30 - Samsung 128GB Evo Select formatted as a 'removable' storage device - did the standard 4GB size write / read test twice without closing apps etc (so bit of a real life test) and once did reboot (waited 5 minutes before launching), ran the accurate test (does write, then reboot again with another 5 minute wait, then does read):
Test 1
Read - 64.01 MB/s
Write - 35.38 MB/s
Test 2
Read - 65.25 MB/s
Write - 33.13 MB/s
Test 3 (accurate test)
Read - 60.56 MB/s
Write - 37.63 MB/s
Based on other benchmarks I have seen for this SD card (~95 MB.s read and ~70 MB/s write), it does appear the V30 is not able to get full speed out of it.
And just for 'fun' here is what the internal memory was capable of in this app (only ran the 4GB test once):
Read - 524.87 MB/s
Write - 199.30 MB/s
I am wondering if even if it were stuck at the slower speeds, would this have any impact on the camera, video, music, etc? I am planning on using a 128G SD card also if I get this phone.

That should be enough to handle 4k and pictures being directly written to the micro SD card. You will want a card that is better than those speeds but there isn't any need to go for anything super expensive that are rated for super fast performance.
Found Out Too late..
While the measurement numbers are great info - I didn't need to run a test, I noticed as soon as I tried to play some PSone and PSP games. Any game with heavy disc access while trying to play (sports games especially, due to commentary) stuttered like I was running them off of an external USB hard drive. Move the game to internal storage and (obviously, from the benchmarks, above) no trouble at all.
This is disappointing, as I picked up this phone expressly due to its specs for playing games (It was on sale, and replaced my cheapie Blu phone). Not the end of the world; I can move games to internal that are particularly problematic, but rather annoying and ironic, as the games most affected are the ones taking up the most space, requiring the extra MicroSD storage...

Go AOSP/non-Stock, format microSD to ext4, flash custom kernel and see how it changes things,
write speed will be improved by 100% (so twice as fast), read speed approx. around 10-20% (or more) compared to exfat.
Also custom kernel got general speed improvements so that might make a difference - haven't tried running anything particularly heavy off the microSD though.
That particular thing is probably the reason why Android/Google doesn't recommend using microSDs - it can really degradate and mess with experience/fun at times

Thank you for this info! I will definitely look into it - Although I just ran a few tests of my OLD phone, (A Blu Vivo 2(?) XL(?) - I forget), and it's read time from the micro Sd is atrocious, like 32 read and 24 write, and yet it plays PSone games just fine from the Micro SD - the SAME Micro SD that the LG V30 is stuttering on (and I've tried a drawer-full, now) - which leads me to believe it's some other type of bottleneck. After all, an actual PSone cd only reads form 150 to 300 KB (not MB) of data per second. Even with a single emulator emulating individual autonomous chips, there should be headroom, I would think, to keep things going.
... Aannnnd this moves me off-topic from this thread - So I'll stop right there.
