Re: How can I test my read speed of my MMC

--------------------------------------------------------------------------------

In XTerminal, As root type: time dd if=/dev/mmcblk0 of=/dev/null bs=4096 count=40000

Mine took 30secs but thats with the MMCPlus Modified kernel and MMCPlus card. I dont know what a good speed for a normal card and/or normal kernel is.

I also have the modified kernel loaded on my 770. I used the zImage-su-18-200639-2gb-mmcplus52Mhz-multiblockw version. My test results with a Kingston 2GB MMC card is:

/home/user # time dd if=/dev/mmcblk0 of=/dev/null bs=4096 count=40000
40000+0 records in
40000+0 records out
real 0m 29.83s
user 0m 0.09s
sys 0m 3.85s

And the result, is exactly as above! I also confirm with a real time clock, and the result is also 29.5 seconds. Well, looks like my patch is alright, and I am curious to see those that did not patch and post what is the time counts for 40000 records on a 2007He2007.36-2 MMC system, the more the merrier, post any system you like, just for the record.
