And here I was thinking everything was fixed now that they differentiated their SMR and CMR drives. That's ridiculous. Guess it's over to Seagate.

A warning for anyone, you should never use 2 hard drives from the same "batch" of hard drives ever (try to buy from multiple different stores and/or models). No matter how high quality and safe the drive, because they are placed in the NAS at the same time and used the same amount, they will die at the same time. And unless you are doing a RAID-6 where you can afford to have 2 drives die at the same time, you will lose everything period. It has happened to numerous people.

This is a great deal, but do not use more then 1 drive for any single NAS system (2 drives if you have a RAID-6 setup) unless you wait at least 6 months between placing them into the NAS. Very important.
Has there been a study that confirms your theory, or is it just your projection?

Had four of these in my synology NAS. Although they are excellent performers, two of them did fail within two years of purchase.

buy the amount they need +extra drives, test them for a few weeks, bad ones are exchanged, use extras one to test, if okay then deploy setup. receive replacements and test as extras to replace damaged deployed drives as needed. Then think why are we using SATA instead of SAS drives?
Whatever. We actually moved over to SSD drives.

No, he is just trying to act like he knows something that everyone else doesn't.

Raid1/mirroring is not the same as backup. Get the drives wherever you want and back them all up properly.
2 drives dying at the same time still breaks a raid1 setup as well.

Um yes actually, lots of them. For example, read any of the many times BackBlaze has many whitepapers around it (actually they have tons of really awesome whitepapers around a LOT of different things you would never even think to have whitepapers around even). I learned all of this multiple times from first hand failures before realizing that there is tons of studies out there explaining why my raids kept failing and I was just being an idiot in how I purchased hardware.

So you think when the data companies order 100's of drives at a time, they ask for each one from a different batch?
Actually I know exactly what data companies do because this is where I learned about this problem from is by the white papers from data companies. Yes they buy 1000's of drives at a time and they are very careful to have them splitup across multiple raids. Do *you* think data companies have only a single raid setup?

facepalm... this is why you backup regardless of raid configuration. Are you not getting it?

Synology or Qnap are great as a starter or no-nonsense NAS. Spend a little more for some basic server hardware ($500-$1000 no drives) and you can go to TrueNAS or Unraid. I do storage for a job, so I like to play with ZFS and Docker on minimal CentOS install at home. I also lean more toward open source.
It's probably overkill for me if I have to spend much (not that these Nas don't go that high), for my needs the basic Nas hopefully will be enough. But thanks, it's something I can check in the future. I build my own gaming pc but never tried anything like this

Waste of $$$ if you're running Windows 10 since it only supports up to 2TB, or 16TB
Say again? I have several Win10 boxes running 4TB drives.

I'm a newbie to this, can I ask what monitoring software you use and is it friendly for beginners? Thanks
There should be several options, even for free.

Google 'SMART drive monitoring tools' or similiar.

I believe Crystal Disk Info does this as well.

Then you're only using 2 TB of each of them. That's the limit unless you jump up to 16 TB.
