Tests Explained:
- Integer: Comparable to other MSM7201a devices and in SKTools listed as one of the fastest.
Only faster devices are Touch HD2 and Samsungs OmniaII, scoreing 813 and 530 respectivly, showing what we already knew, the new generation of ARM's is quite a bit faster.
- Floating Point: Okish with only new CPU's being much faster (HD2 is 5x faster in FPU operations.)
- RAM Access: REDICULOUSLY SLOW, but exactly the same as all other MSM7201a devices. But scoring just around old 200Mhz device speeds. There are PXA2xx based devices with a RAS from 4x that of what our MSM7201a's show to 20x that speed.
- Draw Bitmaps: Okish compared to other MSM devices, but way slower then Intel PXA's and even the HD2 is only 2ce as fast. (PXA's go up to 3x-4x as fast, Omnia 1 and Omnia 2 being nice examples.)
-Main Storage (Write): Here is where it gets interesting and clear something is funky as hell, either the HD has ****ty ROM chips or the interface in Windows Mobile is messed up. There are devices scoring from 2x to 10x the speed the HD does and some of them (notably the Diamond and Sony X1i which are MSM72xx devices) are 10x faster.
-Main Storage (Read): Same as with Write, slow as ****, the Diamond scores 3x the Diamond, same for X1i, with the HD2 surprisingly being able to read its internal storage at 64MB/s! Our HD's around 5MB/s, pitifull, even a Class 2 SD reads 2ce that easily.
- Storage Card (write): I ran this test a billion times and found the score going from 50KB/s to 500KB/s but never higher. There is a serious problem here, I use class 6 SDHC's of several sizes and all of them score very low. The SD interface is slow as hell which I'm certain is a software / driver problem, because I've tested some drivers from other devices, which worked mindbendingly fast.
As you can see, Ram, Internal Storage and SD speed are all lacking extremely.
Compared to other devices (notably, even the Diamond) its quite ridiculous how slow the HD's internal storage really is.
I propose taking a new approach to speeding things up, most other projects so far have been about tweaking graphics drivers, to offload graphics to more optimized routines, streamlining roms, etc etc.
I propose we start looking for ways to get Ram, Internal storage and SD storage speeds up to par with other devices. That is, if its not all limited to hell by substandard hardware. Which would piss me of even more, since the HD is the most expensive phone HTC had at the time and way cheaper devices like the Diamond score much much better.
A few weeks ago, I tested a driver for the SD Interface in Windows Mobile and overal, read and write for the SD were boosted to phenomenal levels, Class 6 cards were actually worth using (while the above results show a class 2 card doesn't even get used right)
Problem was that after a while I was experiencing data corruption on the SD card, mostly after syncing the phone with Outlook to my Exchange account and getting several thousands of small files on there.
I cleaned the card and did the sync again and the same corruption happend.
My tests with big files (MP3's and AVI's) showed no corruption.
So, I'm at least sure that SD speed can be improved quite seriously. And seeing there are devices like the Diamond, which have a lot of the same hardware the HD does, internal storage should be possible to be boosted quite a bit too.
RAM is weird and I don't really see how it can be so bad because of software alone. Did HTC really set us up with ****ty ram chips there? I don't know.
So yeah, anyone with me to explore the storage area to improve the HD's speed?

Micro SD class speeds

I know the differences between the classes, but I'm more concerned about how the speeds effect some what I do on the phone. Currently I have a 16gb Samsung C2 that I took from an Epic. It seems to be working ok, just nothing to write home about. I am thinking about getting a 16-32gb c4 or higher. I'm just curious about what gains I would see
*would the camera be any quicker?
*I assume the gallery would be quite a bit quicker, can somebody verify?
*I use my phone as an mp3 in my car, would the lists load faster? as a player its just fine but it takes a while to load all the artists/albums, which is annoying when I am driving. I thought those were indexed but would a better card help that?
*any other daily activities that would see a direct effect?
I searched, but most people just asked questions I already knew. Thanks

I have a 16gb class 4 and I haven't noticed any significant increase in speed from a 8gb class 2 card both were from sprint don't know the name of them yet

Class 4 cards will record HD without any hiccups. Class 2 skip all day long, because they can only right at 2mb a second which is far to slow for HD.

thanks for the info.

I just put a 16GB Class 6 card in my Evo and it more than doubled the write speed and more than tripled the read speed. I had the stock SD card that came with the phone. I believe it was an 8GB Class 2 SD Card.
I do alot of flashing of new ROMs and such, so the increase in write speed is very noticable when copying files to the SD card. I use to hover around 1.9-2.0MB/sec and now I'm seeing 4-5MB/sec write speeds.

Internal speed

Anyone notice that "internal" calculations seem very slow on the N7? When I use a Cache Cleaner, it calculates cache about 10X slower than my Optimus-V. If I go into settings/apps and open an app, it takes over 30 seconds to compute memory usage (also about 10X slower). I would have thought with this processor this stuff would be "instant"....
Just curious if rooting or Roms would improve this speed, or if I'm the only one with the problem. My only other gripe is small (microscopic) text on many apps. Otherwise it's a fantastic product!

I've noticed this, too. Considering it can perform so well in every other category when benched it's weird that the read/write is so slow. I've been tweaking and benching like a madman though, and I'll post any positive results I find.

The 8gb model has a slower emmc speed than 16gb. Even my 16gb is relatively slow compared to my g2x.
You can try other kernels with a script that improves benchmarks but in use it doesn't really do anything .

SD Card is So Freaking Slow!

I have a PNY U3 Turbo Performance 64GB High Speed MicroSDXC Class 10 UHS-I, up to 90MB/sec Flash Card. It seems to get slower with time. I mean it is literally taking me like 60 seconds to delete a few pictures. The card is formatted to portable storage. I only store music and photos on it. Reformatting offered no improvement. It is borderline unusable.
So, I benchmarked and found that my read speed is about 59 mb per sec and my write speed is 4.4 mb per sec. I can live with the read speed but the write speed is horrible. What gives?

How many pictures are you talking about, and how large are they?

128KB clusters?
I found trying to use 4K clusters in exfat was resulting in the same slowness. Reformatted to 128KB clusters and it flys (~20MB/s write ~70MB/read). Sandisk ultra plus 64GB.

I have this issue as well I have one of the fast Samsung cards. First few months worked great super fast but now takes a while to carry over a gig of pics and music. I also notice lag in loading and delteing photos through the phone

These are normal pics 5-6 MB. There has to be something wrong.

If you find any info/solution let us know.
Im thinking about running it through one of the tests that show the read/write speed, if its not up to par on that I will contact samsung see if its covered under their warranty.

Why not opt for a 128GB sd card? My Moto X Pure will be here Thursday. I have a 64GB in my old phone but I may get 128.

Has the OP tried backing up their data and reformatting the card?

Yes, I have tried this a few times and it did not help. The write speed of this particular card is somewhere between 5 and 9 mb/sec. I have used multiple benchmarking tools that all confirm the same thing. The sad thing, if you drill down into the specifications for a lot of these new sd cards there is no mention of write- speeds. I asked a question similar to my OP on Reddit and had somebody with the same card echo my issue. Terrible write speeds. I am not in the mood to buy another card with great specs only to find it performs poorly in my phone? There is still a part of me that thinks it's hardware or software related and specific to the phone. I can't quite believe that something advertised as "turbo", UHS-1, Class 10, and 90 mb/sec has an actual write speed of 5 mb/sec. It seems criminal.

^^See my post #3. I've found this card to have very good write speeds on the phone of ~14-16 MB/s, reads around 40-50. On the pc through a usb 3 card reader I can write at the speeds posted above.
But yes, unless you drill down, the marketing and advertising doesn't list write speeds. I can see why. It all depends where you'll be using it. I'll be lucky to see sustained 10MB/s read through my dash cam (not sure what the write speed even is) even through the card is capable of 40MB/s +.
I should say, using the moto x, through MTP, I've seen read speeds upwards of 35-40MB/s, write speeds of about 7-10MB. The card is faster through twrp, backup stats indicate ~14-16MB/s.

Microsd card - Which one to use?

Hi All,
Just like to ask. My S7 Edge will be coming next week and I wonder which of my microsd cards is better to use for Mobile Phone specifically for S7 edge.
I have 2 Sandisk Ultra 64GB with attached speedtest result:
microsd_x - higher read but lower in write. i'm using it on my Yi Action Camera currently.
microsd_y - lower read but higher in write. used it on my HTC One M9+
I just like to know your opinion which one will be better for the S7. Will the microsd_x is better for S7 edge since it has higher read speed that can be maximized when the phone reads the apps that i installed to sdcard? will the write speed is just enough for average daily use?
and will my action cam benefit for microsd_y since it has higher write speed and read speed will not be used most of the time?
Please help. need you advise. not sure if my logic is correct based on the speedtest results. or is there a deeper explanation behind it.
Thanks!

I think it will depend on what you use the card for the most. If it's mostly loading apps, then the one with the faster read speed. OTOH, if you mostly use it to store photos or videos you take with the phone, then then the one with the faster write speeds.

i think i will try to test the microsd card with higher read speed first on S7 edge and see if the write speed of the same card will be sufficient for mobile phone use.

The left one seems to peform far better with random IO and is fast enough for 4K recording so that's the one I'd choose unless you copy a lot of lage files to your phone mostly.

Thanks for your suggestion. that is what I'm thinking also, if the write speed is sufficient to record 4K videos. Anyways, I'm not into capturing videos and 1080p is okay for occasional videos. I think i will be using it more for transferring installed apps to microsd and the read speed is definitely faster. But with your recommendation that it can capture 4K videos, then I will be using the left one instead.
I checked the recommended samsung evo+ speeds, the left one image has similar speed with evo+.
