I have two out of twenty WD Black drives that are still operational. I prefer HGST Deskstar NAS (7200). The larger the cache the better.
I agree with Chalenge and Skuzzy
As for the Hitachi (HGST) DeskStar HDD platter Hard Drives, I wouldn't go lower than the 73000/74000 series 7200 rpm ... I also like and prefer the UltraStar enterprise HD models, too...(is early morning and no coffee yet, hope I typed that right)
As for WD drives, I have only 2 in use out of 12 desktop computers, a home server and (2) LG model# N2B1 NAS systems that have built in Blu-ray DL RE-Writers and (2) 2 TB Hitachi HDs, that have ran non stop since April of 2016 (I have one of these each hooked to the TV's in the Den and in my bedroom)
I have the ability to access any computer from any other computer as well as from any TV in the house... including the ability to access any of the NAS' and the Home Network Server...
After witnessing my Mom's computer brick (2) WD Black platter Hard Drive's and (1) WD Blue platter Hard Drive...then having a WD Raptor 450 GB 10,000 rpm HD fail on me, I personally will not allow another WD Drive be installed in to any family members computers ever again...
The 2 WD drives that are still in use are (1) 320 GB HD on an old Windows XP system, with a 250 GB data storage drive on the same system ( and each of them have bad sectors problems )
There was a pretty good discussion/debate in this forum about which manufacturer made the better Hard Drive/most reliable drive....
Maybe someone can research it and repost the link to that discussion/debate...
