[CentOS] hard drive question - WD red

I see a really good price, and better for quantity, for 3TB drives. Now,
I've been down on WD for a couple of years, since I found that they'd
protected certain h/d parms from being changed (like TLER). The ones I'm
looking at are the Red, which seems to be a new color (at least to me),
and one technical review I've read says that they're intended for NAS,
etc, and you can adjust those parms. They're *not* supposed to be
"enterprise" or server grade, but it sounds like they'd work with RAID.

Anyone know anything about them?

       mark, checking before I buy
