A Bad WD Sentinel DX4000 Power Design

A user by the name of Koitsu is reporting that there is an unacceptable power design on the WD Sentinel DX4000 hardware.

In his post Koitsu states that the external 6.3A at 19V power brick is not good enough:

“The unit comes with 5400rpm drives — if you were to shove four 7200rpm drives in there, you almost certainly would be taxing that little brick of an AC adapter. Your drives would start falling off the bus and experiencing strange anomalies during high I/O.”

Koitsu then works out the percentage of power use a single WD2002FAEX drive would require and gives us his findings, which you can find here.
