For one year, I have the WD20EZRX used together with a WD20EARX in an external housing as a backup in a RAID 1 array.
Since 6 months, she now serves as a pure data drive in my current gaming / video editing computer next to a Samsung SSD 840 EVO for the OS and a 1TB WD Blue (WD10EZEX) for my games.
OPERATION
The drive is practically inaudible at idle when accessing one hears occasionally discreet "Geklacker". The temperature is in a well-ventilated cabinet usually only a few degrees above room temperature, and the speed is sufficient for a disk (benchmark by CrystalDiskMark as an image at the end of the review).
Only when renewed access after a period of inactivity, the GREEN begrudge a short pause for reflection accompanied by a short clacking. This feature is called "IntelliPark" and ensures that the read head is moved in a short time without access to the park position and then not again until "ausparken" must.
ATTENTION: In the past there were (especially when used in NAS systems) always the problem that the read head is parked on the basis of "IntelliPark" features permanently in an 8 second intervals, making the specified 300,000 load cycles of GREEN be reached very quickly which can significantly shorten the life of the panel. The number of load cycles can be read via the SMART values. My drives are not affected acutely them thankfully.
While there is an unofficial WDIDLE fix to extend the interval of the read head parking of such officially unsupported "firmware intervention" I leave but generally prefer the finger.
GAMES FOR INAPPROPRIATE
Because some of the 2TB was still on disk space, I originally wanted to use the disk for my games. But at the first game came the sobering realization that the GREEN is not suitable for games. Every minute, sometimes even shorter, the game had a short trailer, every time something had to be recharged, accompanied by the typical short clacking when the read head moves out of the Park position.
Meanwhile I use for my games a WD Blue 1TB (WD10EZEX) because there is no trailer yet other Geruckel.
CONCLUSION
Although I'm not entirely happy with the GREEN series, I trust still on hard drives WD, but with other "color". I would opt for a RED or maybe even a SE for use as a data grave today. Until larger capacity SSDs are affordable, I recommend for games the series BLUE or BLACK for enthusiasts more expensive.
A GREEN I would no longer buy at the moment.
