B3 performance over eSATA
Posted: 08 Mar 2014, 14:45
Hi all,
Here is the situation... in my B3 I just changed my original WD Green 2TB with a WD Red 4TB (works very nicely by the way, the temperatures are rougly the same as with Green 2TB), and then I connected the Green 2TB with B3 over eSATA (with a external disk enclosure of course).
Now, I created a manual entry rsync entry in crontab, where I basically ordered a copy of about 1,8TB of data from B3 to external disk. At this very moment it already lasts roughly 24 hours, and it managed to copy roughly 1TB of data - this ammount to about 45.000 files.
I find this performance very poor - when calcualted, this is about 12MB per second. This kind of transfer speed I get over my 100Mbps LAN connection. Over 1 Gbps connection I get speeds (with B3) just around 25MB/s.
Shouldn the speed over the eSATA be limited by disk performance? Honestly, I expected at least 50 MB/s over eSATA, but this not even close to it.
Could there be aproblem with eSATA port on B3?
