Segate 500g/7200rpm drive 5v .5amp
OCZ Arc100 5v 1amp
OCZ Vertex 5v .5amp

My Vertex appears stable, the ARC100 wont stay online. drives are not drives either.

My 2 cents:

My drive is a 500GB Western Digital WD5000BEVT.
It seemed to work fine attached to the SATA port with my power cord so that I have moved bananian to /dev/sda1
Although, now, I am noticing some errors in /var/log/messages:

Copy the Code
Anyway, looking around for some more information related to upgrading the firmware, I have noticed a feature I did not know: the R.P.S. (Reduced Power Spinup)
Western Digital says:
2.5-inch drives are primarily utilized in notebook systems. To provide the fast spinup preferred in these systems, the drive can consume approximately 1A of power which does not lend itself to the external hard drive market. To address both the external 2.5-inch drive marketplace requirements as well as the notebook marketplace requirements, WD has created the capability to configure its 2.5-inch drives to spin up using minimal power consumption


Depending on the drive, there may be a jumper setting which enables this feature.
Here is the jumper settings for my drive:

Reduced Power Spinup - Western Digital

I am about to try this right now. Do you know how I could measure any difference and share my experience in this forum ?

Maybe this would help some of us ?
