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 follow Netgears advices - that ended with thousands of pictures lost since I started replacing 2TB disks with these "magnificent" HCL

Guess what - I got a VERY pissed off wife here she has lost her private pictures - so have I, thank you very much Western Digital and Netgear

I am stuck with 4 of these chinaware shitty disks - can't be returned as long as they "live" WD don't accept returns before their customers has lost their data

Yes bad day for me today

  • I have 2x WD30EFRX, as I was early adopter, they are probably first models that got into the market.

    So far no problems...they are cool & quiet...

    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.

    Interesting that the WD20 and WD30 have identical specs throughout. I was starting to wonder if it was the same drive just with the WD20 just firmware size limited. Then I saw that the weight is slightly different. I'm surprised then that it there's more platters in the WD30, it really does consume exactly the same power as the WD20.

    Either way I expect it'll be within about 5% since the WD40 is only 10% more.

    Thanks for the responses. I'll probably get the 3TB units since they're only a fraction more expensive than the 2TB drives.
