Howdy,

Tuxic's recent thread brought me back to looking at SDDs again.  I
recently learned about HDDs having SMR instead of PMR and how that can
be a negative in some situations.  I've since found out that one of my
/home drives is a SMR.  I didn't know to look at that when I bought it. 
So, before I find a SDD to buy, what are some things I should look for
it to have and what are things I should avoid?  I'm sure SMR and PMR
doesn't apply here but I bet you gurus have ran up on things the hard
way to either avoid or make sure SDDs have. 

As is, the OS itself is on sda.  That includes everything except /home
which is on two drives using LVM.  It's about 9TBs or so I think.  One
6TB drive, SMR I'm afraid to admit, and a 3TB drive that I'm pretty sure
is PMR. I may put /var on a HDD since it changes a good bit.  Everything
else, except /home, would be on the SDD. 

Anyone care to share? 

While at it, if I look for a NAS type HDD, would all those be PMR
instead of SMR?  From my understanding that should be correct.  Mostly I
buy WD, Seagate and Samsung.  I've had a WD fail, I've had a Seagate
fail. I'm not looking for a HDD flame up.  O_o  I'm starting to look at
HGST.  I think I got the spelling correct.  Never had one tho.

Thoughts?
