I also made a iozone Test using USB instead of SATA, the results are similar. So I think the cable i ...
Similar results with USB 2.0? You get read throughput exceeding ~35 MB/s? If you're talking about slow write performance I've no idea what's going on.
The performance of disk access is affected by many factors (CPU and DRAM clock frequency, kernel config, filesystem settings, partition layout and so on) that it's hard to get a clue why you get only 25%-30% of the maximum throughput already measured between SATA disks and A20 SoC without knowing anything about your installation. In case you're only testing against your Lian Li enclosure I would suggest using another single disk to nail the problem down.
Or did you setup a RAID and test against that currently?
