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.
