I'm not sure on the TLER issues by themselves, but after the nightmares I have gone through dealing with the 'green drives', which have both the TLER issue and the IntelliPower head parking issues, I would just stay away from it all entirely and pay extra for the 'RAID Editiion' drives.
Just out of curiosity, I took a peek a newegg. Western Digital RE3 WD1002FBYS 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive are only $129. vs. $89 for the 'regular' black drives. 45% higher price, but it is my understanding that the 'RAID Edition' ones also are physically constructed for longer life, lower vibration levels, etc. On Oct 5, 2010, at 1:30 PM, Roy Sigurd Karlsbakk wrote: > Hi all > > I just discovered WD Black drives are rumored not to be set to allow TLER. > Does anyone know how much performance impact the lack of TLER might have on a > large pool?
