  12. Conclusion



Just as the WD 3TB counterpart, the WD20EFRX a foam to decrease vibration between the drive and the PCB & a thermal pad in the middle to help the controller in heat dissipation.


Same controllers and same Cache: Micron 88I9346-TFJ2 Controller and Hynix DDR2 64MB Cache. The only difference? 1 platter short.

I would like to see if this would improve the Large file transfers and Access times.


The drive stays pretty cool in closed test system considering that current ambience here is about 29-31 +/- depending on the time during the day and even lower during the night. This is very important to look when it comes to NAS, especially with personal NAS box where you get to connect 2 drives stacked on top of each other.

During a 30 minute Anvil endurance testing, the maximum temperature that I was able to touch on my system is 32 degrees, that 3-4 degrees lower than WD30EFRX drive.
