(micro) SDCard benchmark, testing your Android device disk I/O performance

ArcTools now offers a I/O benchmark test feature to evaluate the performance of your device internal or SDcard storage. Please note that this benchmark is a work in progress and we may adjust the benchmarking procedure based on our users feedback.

We are trying to help building a list of reliable, fast and affordable microSD cards. With the help of users reports, we will try to identify fake or unreliable cards that you should avoid.

The I/O test consists on writing and reading a test file of about 90 MB. The file is made with random data, written to disk and read again. All operations include a verification thru a CRC32 test to make sure there is no data corruption.

Usage:
Enter your Username, that will identify your reports on this page
Select device to test, either Internal Flash storage or SDCard (if available)
If you are testing an SDCard device, please select the Vendor, card Class and specify some details to clearly identify the card in the “Card description” edit zone.
Press Start button
Wait a few minutes until the test finished
Test results will be displayed on screen and uploaded to this site
Graphics and data table on this page will get updated after a few minutes

Thanks goes to Florian (@archoslounge) for this help translating this article and Jean-Luc for testing the application.

Iphone4S的数据如下，而我的Note1，W只有7.8M，硬件性能的差距其实挺明显：

I'm curious about if I/O performance of iPhone 4S has enhanced or the same...

Could someone who has an iPhone 4S try to iBenchmark! and share the scores ?

itunes.apple.com/sk/app/ibenchmark!/id423223184?mt=8

iBenchmark! is free btw...

My scores for iPhone 4 w/ iOS [No JB] are here below:

Memory Allocation: 200.3 per sec.
Memory Copy: 863.1 per sec.
Disk Write: 20.5 MB/s
Disk Read: 101.2 MB/s
