Likely the desktop systems are not providing any power through the eSATA port.  You will need to plug the USB cable in as well provide power for the drive.

I concur with kode99, I have faced a similar problem before and plugging in an external power adapter to the drive helped resolve the issue for me with desktops.

from the specs :  eSATA interface (plug directly into any compatible motherboard or laptop with powered eSATA port)  so probably those pc's do not have a powered eSata port  (as kode 99 said)

The esata interface is connected on the motherboard. Is it possible the interface to be non powered esata ports?

To get power out of SATA you need 'eSATAp' ports,  heres a link with pictures


eSATAp looks a bit different.  You can get a eSATAp adapter bracket for desktop systems if you don't want to use the extra cable.

Not sure how many desktop boards you would find these eSATAp ports on.  All my eSATA stuff is too power hungry to power without a external adapter so I never noticed the different ports.   USB3 seems to be on many new boards and will probably overshadow eSATA for most consumer products.

Anyway the drive specs from the manufacturer list 90 mb/s for reads so your benching is pretty close.

Here's a link to the manufacturer's product page,


Apparently the drive came with a USB cable for powering it with a plain eSATA port.
