There was recently a WP7 benchmarking app called WP BENCH released in the market and I am interested to see how the stock sd card is functioning compared to the user replaced sd cards. The benchmark consists of 3 main parts. These are CPU, DATA and GPU.
Stock 16GB SD Card (NoDo)
*non typical result
CPU
Sequential: 21558*-10875 ms
Parallel: 13058*-10312 ms
Data
memory: 13.07-9.8* MB/s
storage: 3.56-0.19* MB/s
GPU
Frames: 698-666*
avg: 23-22 FPS
Here are my results. DVP unlocked 8GB NoDo Tmo USA. Base on my 5 tests, the Storage speed on test #1 is .25MB/s and the others are ~3MB/s+.
Test #1 with reboot
Sequential 10888ms, Parallel 10470ms
Memory 13.07MB/s, Storage 0.25MB/s
694 frames, avg: 23FPS
Updates:
Test #2 no reboot
Sequential 10859ms, Parallel 10404ms
Memory 13.07MB/s, Storage 3.27MB/s
676 frames, avg: 22FPS
Test #3 no reboot
Sequential 10938ms, Parallel 10414ms
Memory 13.07MB/s, Storage 3.02MB/s
689 frames, avg: 23FPS
Test #4 with reboot and #5 without reboot
results were consistant with tests #2 and #3.
My storage on DVP 8GB no-do was 3MB/s

Same here on my pre-nodo 8GB DVP.
FWIW I also tried on a stock Samsung Focus (no SD card, no updates) and got 2.6MB/s.
I have a 32GB Transcend card (upgraded 16GB model), no NoDo (OS version 7008).

DATA @ 0.8 MB

Installed NoDo on my 8GB and now getting 3.25MB/s pretty reliably. Pre-NoDo was 3.0MB, so results didn't change much and are probably within the margin of error.
16GB Stock card....
First Run:
Memory : 13.07mb/s
Storage : 0.14mb/s
Second Run:
Memory : 12.9 mb/s
Storage : 0.19mb/s
Third Run:
Memory : 9.8 mb/s
Storage : 0.13 mb/s
So am I to believe that the 'Memory' test was for reading and the 'Storage' was for writing?
If this is the case, these damn cards are as defective as could be. I know 2 other guys with Venue Pro 16 GB and they both have the same problem.
How the hell do they get an entire warehouse of defective cards? Did they buy these things refurbished?
Here are my stats based on a 8GB stock Dell Venue Pro pre-nodo:
Test #1 - Power Off & Power On
CPU: Sequential 10866 / Parallel 10471 - 21337ms
DATA: Memory 13.07 / Storage 3.56 - 14810ms
GPU: Frames 694 / Average 23
Test #2 - after 15 minutes of browsing & calls
CPU: Sequential 10868 / Parallel 10470 - 21338ms
DATA: Memory 13.07 / Storage 0.53 - 77737ms
GPU: Frames 692 / Average 23
Test #3 - after 30 minutes of idle
CPU: Sequential 10884 / Parallel 10468 - 21352ms
DATA: Memory 13.07 / Storage 3.56 - 15007ms
GPU: Frames 681 / Average 23
manually replaced with Sandisk 32G Class 2 after NoDo (changed dehydrateonpause to 0):
Test 1 @ 0.8m:
Memory 13.07m
Storage 3.27m
Frame:668 average:22 FPS
Test 2 @ 0.8m：
Memory 13.07m
Storage 3.02m
Frame:660 average:22 FPS
So who's got the best 32gb sd card?
http://www.newegg.ca/Product/Product.aspx?Item=N82E16820220452&cm_re=32gb-_-20-220-452-_-Product
And will a class 10 word, or does it have to be 2?
Updated my 16gb DVP w/ NoDo to 32gb Sandisk class 2
Did 2 test runs immediately after
1) installing 32gb micro sdhc
2) set up phone
3) set up all my accounts
4) installed 60 apps & games over wifi
5) synced with PC, copying pictures, videos, and songs totalling 11 GB
AND I HAVEN'T FROZEN OR HAD TO REBOOT ONCE!!!
CPU
sequential: 11049, 11068 ms
parallel: 10486, 10322 ms
DATA @ 0.8 MB
memory: 13.07, 13.07 MB/s
storage: 3.27, 3.27 MB/s <-- MUCH IMPROVED!
GPU
23, 22 avg FPS
Also, the ##634# CIT sd card test now shows status 0 OK.
All in all, I'd say the sd card swap was a huge success.
I got a class 4 SanDisk from Amzn and the write speed dropped (from previous 8 GB SanDisk class 4) from 3 MB/s to 0.64 MB/s.
Update: Ok, just reinstalled and re-ran the WP Bench app - and data performance shows 13.07 MB/s for reads and 3.27 MB/s for write. I say the WP Bench app has issues
For those interested, I posted about my experience in upgrading to a 32gb card.

You´re right. It happens to me as well. I have a Samsung Focus, NoDo installed (with Chevron.Updater), and a Sandisk 16Gb Class 4 loaded with 13Gb.
The storage speed varies from 0,18 to 4.9mb/s but the higher speeds (above 3mb/s) I only got during the first 3 or maybe 4 times running Wp Bench.
Nevertheless, the usage of my device has no lags at all, even when WP Bench shows a slow storage speed.
So, I think that this odd speed variation is due to a WP Bench´s issue or, even if it doesn´t has an issue, the way that WP7 manages the device´s memory is causing this odd behavior on WP Bench´s speed results.
What I do see - and I've seen others post about it as well is that when you download large apps (Fruit Ninja, Star Wars game, etc), the phone grinds to a halt. I didn't have to pull the battery, but I did have to do a power-off/on. I noticed that leaving the phone in the download screen helps - takes a looooong time to download but it does eventually finish.
Don't know if DVP firmware or Mango or something else is needed to address this.
I do have 14 of 32 filled.

It seems that you´re having a microsd card incompability with your device. Check this thread below where I have recommended a microsd card that doesn´t present any incompability issues like slowness, auto-resets and data loss.

Here's the test results for my custom 32gb DVP w/ FW 212 & Mango 7712
CPU
sequential: 8251 ms (improved from 11055)
parallel: 7792 ms (improved from 10400)
DATA @ 0.8 MB
memory: 13.07 MB/s (same)
storage: 13.07 MB/s (improved from 3.27?!)
GPU
23 avg FPS (same)
Looks like either the new mango or the new FW really boosted my cpu and data/storage scores... anybody else care to share results? I'm interested to see what improved with just the new FW, so if somebody can run the test on NoDo w/ and w/o the new FW that'd be great.
I just tested our TF101 with "sd card tester" and the write speeds are really slow - 2.24 MB/s for a 472MB test file while the read is pretty decent - 12.09 MB/s. Compared with my new Kingmax MicroSD Class 6 doing :
read speed - 9.89 MB/s average
write speed - 10.81 MB/s average
How's it possible that the write speed is so incredibly slow? Could anyone test it out with the "sd card tester" app from the Android Market and let me know?
i got 9.59 write speed and 11.54 read speed
damn...
the internal memory is so slow at writing..
i use a cache of 3072 with 300mb test file lenght
internal sd card:
write 2.68 mb/s
read 19.97 mb/s
class 6 external card
write 10.44 mb/s
read 18.66 mb/s
Internal
Write 8.18
Read 16.07
External 8Gb MicroSDHC class4
Write 43.77
Read 43.29
FullSD Panasonic HighSpeed
Write 31.7
Read043.78
FWIW my write to internal SD was ~5 mb/s initially. I freed up about 6 gigs space by deleting some video content and it improved to close to 9 mb/s.
Those with > 5mb write speed, are you guys on custom or stock rom?
also guys please try it on a larger test file like > 2gb if you have the space or as much as you can, the results would be more accurate. using a small test file i could get around 9mb too
Hi all,
What's the maximum speed the Note 3 can read and write to its expanded micro sd card?
As just got a Samsung 64Gb Pro and I'm only getting 20mb/sec read and write. The card is supposedly be 90/80 read/write.
Thanks
Paul
Reading should be fine... but writing seem to max out 20mb/s - so you're getting the average/max speed, but you will notice the file type and size will have impact on speeds. I've seen upto 34mb/s on some mp3 or image files, but otherwise speeds hover around 20.
Wish knew that before right? Could have saved some money on getting a slightly slower sd card, but if you use a good card reader (yeah you have to remove the sd card) you will get your max speeds.
I noticed little issue with my brand new Moto X Play (upgraded to Android 6.0). I bought sd card Kingston microSDXC 64 GB UHS-I U3 90 MB/s read and 80 MB/s write, put to device and formatted as internal memory. After successful formatting phone displays popup: "Card is too slow". I did benchmark (A1 SD Bench). Results: Read about 20 MB/s and Write about 15 MB/s. The strange thing is that I do not feel any lag when I launching app installed on sd card (it launches nearly in the same time as from phone internal storage). Has anyone had a similar problem?

I experienced the same thing with my phone. After formatting my new strontium 64 gb uhs 1 card for internal show, it displayed the 'card too slow" message. After running the benchmark test, I got around 25mbps read and 14 mbps write speed.
Planning to return the card. How has your experience been so far using this card?
