My WD RED WD30EFRX experience
2 out of six WD30EFRX has failed- this is my third year with readynas ultra6 - and this disks are the first to fail on me. All other disks have not been on the HCL. This time I wanted to be smart and ...
Temperature scales with power use (all the power gets converted to heat, one way or another).
According to WDC's data sheet (http://www.wdc.com/wdproducts/library/S ... 771442.pdf) the WD30EFRX has the same average power spec as the WD20EFRX, so the temperature should be similar. Both models also have the same acoustic specs. Per the data sheet, the new WD40EFRX uses 10% more power and is slightly noisier. Of course if the higher capacity means you can use fewer drives, the WD40EFRX would save you power.
