Ability to handle heat and vibration is no more subjective than the safety ratings of cars. They've been tested, and are able to make that claim (objective). However personally, I think it would take so long for vibration or even heat to kill a drive that you will have already upgraded / replaced it. Only in extreme conditions of either would a drive fail under 5 years as a result. So ultimately I'd also say it's a marketing gimmick. Personal opinion supported by no real hard evidence. Just have had hardware survive being in a house closet with no ventilation and old 15k disks that vibrated the shit out of all the other 7200rpm disks :-) Hey, I was young.
I'm pretty sure there is no communication happening with TLER - it is simply the disk taking less time on error and then letting the raid card or OS decide how to handle it. Instead of stalling for several minutes on an error trying to fix it internally, it only stalls for 7 seconds. If it stalls for too long (without TLER could be several minutes) then the controller/OS considers the entire drive degraded, whereas with TLER (and similar tech) it only stalls briefly - enough time for the OS/controller to realize it cannot write/read to/from that sector but the drive is still active.
Drives will fail from all vendors, it is how they handle it (RMA process) that should influence your decision. I don't think the WD department will care if it's blue red purple green, they'll treat you the same either way.
Dont put faith in any brand and expect the disk to die and plan accordingly.
@Zygizz Use partpicker or the like, and organize by price per gb and find the best deal. If you want to use FreeNAS I'd suggest getting a drive labeled for NASs to make sure you get a drive with error recovery. Seagate tends to be the cheapest, and I can personally speak for their RMA process (being my drive died at 11 months) as being excellent. Though you won't find much love for them from other users because there's a lot of complaints for failures. However since they are the cheapest, more people buy them - thus more there's just going to be more people to complain. So take it with a grain of salt.
Most "extended" mouse pads are 30+ euros usually, but if you look around you might find a good deal on one. Or just search for "extended mouse pad" and see if you can find a cheap off-brand one.
The following pads are mostly just plain black, with maybe just a small logo in one corner:
Perixx DX1000XXL/DX2000XXL
HyperX Fury Pro Gaming Mouse Pad XL
Mionix Sargas 900
Corsair MM200 Extended
SteelSeries QcK XXL
