NAS specific hard drives

[Mr crowley]

Hi
I'm currently speccing a nas which will be for home use, for keeping general media on. I'm thinking of using freenas, and i'm just looking at the requirements which recommend specific NAS hard drives such as WD red. I was going to use 4x 3tb drives with the ZFS feature to provide raid, to have 6tb storage which will be mirrored, so would this eliminate the need to use top notch hard drives? If so, the only advantages remaining with the WD red would be noise/power consumption?
I suppose another option would be to not use the ZFS raid and just trust the better hard drives, although this seems less safe to me

Yes thanks for the info about the raid, i'm just researching as I go so point taken. Looking at getting the hardware soon as I've got some error checking ram on the way, just trying to nail down the minimum cpu/mobo spec which would run well as on the freenas forums people report ZFS being a bit more power hungry
