Hello, I'd stay away from Toshiba and Intenso drives, which are just overlabled Toshiba drives at least here in Europe. They are extremly loud and get quite hot compared to WD and Seagate. And be careful with Seagate ST4000DM00X. The -0 are good drives, but the -3 is a SMR (shingled magnetic recording) drive. At least for raid6 they don't work. A friend of mine has two and they are kicked out of the array on a regular basis. I don't know what kind of technology the -6 uses and I don't know if they might work in a Raid1 setup. At least for raid6 SMR drives don't seem to work. I personally don't use ERC-capable drives and increase the timeout in /etc/rc.local for each drive: echo 180 > /sys/block/sdX/device/timeout I run a ten drives raid6 based on 4 tb drives and had no problems so far. I have a lot of WD Green and cheap Seagates. To me raid means random array of inexpensive drives, so I see no point in buying expensive WD REDs. Keep in mind: A two disk raid1 with the cheapest, crappiest drives is still much saver than one single expensive disk, because any disk can fail. Two premium drives in a raid1 is a waste of money in my opinion. For a private living room setup I would consider 5600 rpm drives. They are much quieter than 7200 rpm drives. Here the drive models I use: WDC WD40EZRX-00SPEB0 ST4000DM000-1F2168 ST4000DM000-1F2168 WDC WD40PURX-64GVNY0 WDC WD40PURX-64GVNY0 WDC WD40EZRX-00SPEB0 ST4000DM000-2AE166 ST4000DM000-1F2168 ST4000NM0033-9ZM170 ST4000VM000-1F3168 All bought second handed.
