Should I sell my loud and power hungry (10 W idle) WD Black 2TB drives for the RED?? There only 4 months old and maybe could sell them for 100 a piece.

You really shouldn't ask the question that way. You're the best judge of what you should do for your situation. You seem to already know the pros & cons of each. Black... longer warranty, faster seek, louder, more power hungry. Red... opposite. You may want to look into if the Blacks have manageable TLER as I didn't look.

What Western Digital has to say.

I'd undoubtedly go Red if I were buying/building today.

WD Black doesn't have TLER unfortunately but is 7200 RPM, the new WD Black 4TB are faster then the Reds at sustained writes while WD Black 2TB are slower then any RED. This really doesn't do anything for me, I don't think but power difference is big but I don't think it beats the 2 year warranty additional that WD Black offers but I was looking at enterprise drives with TLER still expensive.

At the bottom of the thread that the link takes you to WD that saids that it is

"Critical: WD Black, WD Green, and WD Blue hard drives are not recommended for and are not warranted for use in RAID environments utilizing Enterprise HBAs and/or expanders and in multi-bay chassis, as they are not designed for, nor tested in, these specific types of RAID applications."

I'm not using Raid card or anything but using the motherboard SATA controller not in hardware RAID of course so maybe this doesn't apply to me but I am using RAIDZ2.
It doesn't specifically state and separate software RAID like ZFS and suggests that TLER is needed which are there more expensive enterprise drives. I did some searching I can't find any definitive answer or explanation on whether ZFS could benefit or suffer from using TLER. I'm thinking that its probably in between and negligible in most environments, in my particular environment its for heavy home use and not necessarily a critical environment but I am using 4 WD Blacks in Raid Z2.

Any system where you must rely on more than 1 disk in an array-like system can always benefit from TLER.

To expand on what noobsauce80 said, it's again your choice. I run a 6x2TB RAID-Z2 setup. If my drive encounters a marginal or faulty sector, do I want it to sit there trying to recover/read that sector for some (potentially long) period of time, or do I want it to go ahead and give up so ZFS can use its parity to (seamlessly) provide the data? Keep in mind the marginal sector will likely be addressed the next time you do a scrub. The deep error recovery process is a nice feature, but it's not necessarily nice on a good FreeNAS system. I wouldn't throw my NAS from a 3rd story window because it doesn't support TLER, but if I were building today, I'd use drives that support it.
