I was curious about the hard drive speed between a pre-built NAS and a H3 NAS
I was unable to load Iozone on the Lenovo NAS
 
Equipment:
NAS1
Orange PI PC
4 port hub, USB 2.0, 5V/3A powered
Inateck FE2005 2.5†HDD enclosure, JMS567 chipset
Seagate, 2.5â€, ST1000LM024, 1T 5400rpm
 
NAS2
Lenovo Iomega EZ Media
armv5tel
Debian 7 wheezy (Original OS)
Seagate 3.5“ 1T, 7200 rpm
 
Results:
Orange Pi PC
 hdparm -t --direct --offset 500 /dev/sda
 Timing O_DIRECT disk reads (offset 500 GB): 102 MB in  3.01 seconds =  33.88 MB/sec
 
Lenovo
hdparm -t --direct --offset 500 /dev/sda
 Timing O_DIRECT disk reads (offset 500 GB): 308 MB in  3.00 seconds = 102.60 MB/sec
 
 
Dmesg reported several errors with the HDD(/dev/sda) when it was connected directly to the on-board usb.  I solved it by passing through a powered usb hub.  There appears to be current limits to the on-board USB.
