dikkiedirk Posted February 14, 2013 Share Posted February 14, 2013 Eventhough I promised myself never to buy a WD drive again, after the rather bad experience with some WD20EARS, I took the plunge and ordered me a WD30EFRX (AKA WD RED). QUestions are: Should WDIDLE be runon this drive? Is it an Advanced Format drive? Should i specify the -A option when preclearing? Quote Link to comment
Automatic Posted February 14, 2013 Share Posted February 14, 2013 Can I just ask what your bad experience was? I myself have never had anything go bad with Western Digital and I'm about to buy three more of their 3TB red drives. Quote Link to comment
mcs Posted February 14, 2013 Share Posted February 14, 2013 Dont know about WDIDLE. -A option is ignored when preclearing 3TB+ drives. Quote Link to comment
BobPhoenix Posted February 14, 2013 Share Posted February 14, 2013 NO don't run it. There is NO problem with LCCs on the RED drives. They are designed for NAS boxes rather than low power so they don't need to park the heads as often. I have some REDs myself and I'll have to verify tonight but I believe one has about 50 LCC with a 1000 power on hours. Edit: I was a little off it is 80 LCC count and 2444 power on hours: smartctl 5.40 2010-10-16 r3189 [i486-slackware-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Device Model: WDC WD20EFRX-68AX9N0 Serial Number: WD-WMC300511324 Firmware Version: 80.00A80 User Capacity: 2,000,398,934,016 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 9 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Thu Feb 14 17:04:44 2013 CST SMART support is: Available - device has SMART capability.

dikkiedirk Posted February 14, 2013 Author Share Posted February 14, 2013 Can I just ask what your bad experience was? I myself have never had anything go bad with Western Digital and I'm about to buy three more of their 3TB red drives. I had 4 in my NAS, 3 of them got an increasing amount of reallocated and pending secors in SMART after 12-15months, all have been RMAd and on the positive side were advanced replaced. Currently here in Europe WD is the only one that seems to offer advanced replacement. Maybe it was a bad batch of drives. At that time I also learned about WDIDLE. I hadn't used it on the drives that went bad. My NAS did signal the bad disks and were replaced in time. But replacing the disk and rebuilding a RAID5 array is annoying and doing this 3 time in 2 months pissed me off. Excuse me for the bad language. There are still a couple of WD20EARS the seem to hold fine (knock on wood). I just hope the WD30EFRX will be a better experience. Quote Link to comment

Lots of the negative reviews of drives on places like Newegg are for exactly the same complaints listed here and I think it's unfair to the manufacturers. Green drives are not intended to be used in always spun up RAID5 arrays. wdidle3 can help but the firmware on the drives is simply not designed to cope with that type of usage. This is the whole reason the Red series of drives was created. Before this you really needed to use pro-sumer (like the WD Black series) or enterprise class drives in RAID5 arrays to avoid those problems. Those drives were a lot more expensive so people just bought green drives and then they'd fail. Unfortunately Red drives still have enough of a premium that people will probably still continue to buy greens for RAID5 and they'll continue to fail. That's one of the great features of unraid, that these green drives can be used without those issues. Quote Link to comment
