Hello! I've tried USB flash drive on older boards. Got 2-3MB/sec write/read speed with cpu LOAD 100%.

Can anyone share info regarding microSD or USB write/read speed on newer boards like RB750Gr3?

Thanks.

Thanks. Actually that's very nice. I have 100Mbit network so rate would be limited to 10MB/sec and I wont overload the router.

I didnt expect such high rate from router. Ordered that board... will test it out on weekend, will share my results.

Okey so I tested so far few USB Flash Drives, doesnt matter ftp/samba or ext3/fat32 - Write Speed 2-3MB/sec :( It takes only 10% CPU load, but speed the way to slow... Same flash drives connected to PC are writable @ 10-12MB/second.

Using micro SD card is much better. I'm getting 6.5MB/second write speed at 16GB class 10 card. It takes about 20% CPU load.

I dont have USB hard drive to test at the moment, will post info later.
