My mobo is just old enough to not support NVMe drives. I checked on that a while back. It'll be old school SDDs, well, the ones that mount hardware wise like HDDs anyway. It's not like SDDs are really that old. Avoid flash. Got it. A couple I looked at mentioned NAND. I'm somewhat familiar with AND/NAND gates so I think those are different from flash.

I figure that should weed out SMR drives pretty quickly. I don't mind it to much on my backup drive but I'm hoping to get rid of the one I have for /home and expand a bit. I may buy a 8TB drive and replace the 6TB drive that I currently have that is SMR. Later, I'll replace the 3TB with either a 6TB or 8TB drive. Since my external drive is 8TBs, I may have to recompute my backup drive situation. I'm likely to hit a few walls on that. Plus, NAS drives are designed more for my usage anyway. I have my system on 24/7. It's rare that I reboot since I run my TV off this rig plus am always downloading stuff. Heck, if it wasn't for updates to KDE and friends, I wouldn't even logout very often. >> From my understanding that should be correct. Mostly I >> buy WD, Seagate and Samsung.

What I've learned about hard drives is this, they break, regardless of brands. That said, there is some batches that prove to be problems but other than that, it's just a matter of time. None of them are designed to last forever. Even tho I've had a WD fail before, I still think they are very good. I just avoid those that are not made to handle my usage, being on 24/7 plus lots of read/writes. Thanks much for the info. Avoid flash. NAS should avoid SMR drives. Dale :-) :-)
