novice here. are four of these 12tb drives good for plex using a 4 bay nas? just using to watch library of tv shows & movies. any 4 bay endorsements?
These drives will be more than enough. I would strongly recommended that you run a test on the drives before committing to using them and adding all your media to it. Also, RAID...RAID....RAID...RAID... well redundancy is key when using large pools of data. Good luck with your build!

What's a simple, cheap way to get these into a raid for redundancy if I don't have one yet? I have an unused desktop, can I plug them into that or do I need extra hardware?
Quote from lastwraith View quoted comment :
Software raid - unRaid, OMV, TrueNAS Scale, etc.

This a thousand times. If you have a spare desktop these will run fantastic. Depending on your needs, one is better than others. If you are going media sever will some files shares, I would suggest unRaid since you can mix and match your drive pools/arrays. TrueNAS is another great option but you have to keep your arrays planned before implementing.

I suggest you look up what those two servers can do and can't do before committing to one. I have moved away from FreeNAS (TrueNAS) and to unRaid since this I much prefer having the ability to add "mix and matched" drives to my arrays whenever I come across deals like these. unRaid is not free so that is something to keep in mind.

Earnestly recommend everyone stay away from refurb HDDs. Even when you don't lose any data, you lose whatever "value" you think you get from these drives when you consider the amount of time you will spend "recovering". *ugh*

...find it a bit ironic everyone testing their drives when they get them and declaring them "good". I'd rather have a drive fail right away than find out 6 months later the entire backup array is full of swiss-cheese bit-rot. Units with refurb drives are constant "projects". If you get enough spare drives on hand and enough redundancy in your unit to not worry about them, that's about the same cost as just going with new in the first place.. but with no peace of mind.

Well if they did, this drive would be either of the two:
1. Significantly more expensive than what it is being sold for because of the extra cost going into it
2. Questionable in terms of its reliability, now that it has been "finagled" with, if you follow my meaning!
Filling Helium to a vacuum chamber is the same as filling helium to a balloon. Just pressure valve. The weld/seal is the same as the guy does with the air conditioner. Helium is helium you cannot mix with anything else. The most concern is helium leaking regardless of refill or not.

Well I guess you didn't get my 2nd point. Will you trust the drive to be in good condition after this is done? I would be hesitant. There are certain things I would be ok with at the time of manufacturing but I would not be ok with at a later date which would potentially jeopardize the drives state. The impact may not be immediate but I would rather this didn't take place. I would rather take the drive as is since it has been running fool proof for years, than have it "rewelded" prior to my purchase. What I'm saying is that I just don't know enough about the process to deem this as a drive in "good shape"

thanks. it appears raid 5 is for me. it's when you have 4 total drives and the 4th one protects the other 3 from all losses, correct? i'm a multiple copy person, and wonder if a 5 bay nas with 2 discs protecting the other 3 (raid 6?) is wiser? and suggested model/s?

also, how is running the disc test you mention, done?

Look up the ugreen Kickstarter. They have a NAS with great hardware (software is still to be determined), but you'd have to wait until June. I'm okay with it because I don't plan on using it for much beyond a NAS and maybe Plex server. If you are looking to use it for more, go with a Synology.

yes, i've been following the ugreen. are these 12tb drives a good option in the ugreen 4 bay? i ask since i couldn't test them until i'd get the ugreen.

Quote from heibakarii View quoted comment :
I need help. I cannot convert this HDD from MBR to GPT. I have tried to convert it using various items but it only allows me to make two partitions and a large portion of it remains unusable. Any suggestions ? My OS is windows 10.
You should do mbr2gpt using a bootable USB (or at least using Windows booted from another disk) - so basically, don't try to convert the system drive while it's in use.
Having said that, here are my notes on using mbr2gpt. Beware, they are long....

In CMD, do this:

Type: diskpart
Type: list disk
Note the Disk # for your C:, which should NOT show an * in the GPT column
Type: exit
Type: mbr2gpt /validate /disk:X, where X is the # of the disk you
got from diskpart for your C:
If it validates okay, you're good to go. If not, stop because
there is some problem!
Type: mbr2gpt /convert /disk:X to do the actual conversion

DELL ERROR = "Cannot perform layout conversion. Error: 0x00000000"
Issue the following command instead =
mbr2gpt /convert /disk:0 /map:222=ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
(222 is for the Dell OEM Recovery partition, and the other string is
the GUID for an MS Basic Data Partition under GPT)

Reboot your computer, and don't forget to change boot mode to UEFI

ERROR1
If there is a "disk layout validation failed" error
*Shrink the system partition in Disk Manager by some amount (200MB was
mentioned, I used 600MB without issue)
Go to Disk Manager -> Select disk # (matching diskpart #) you want
convert and select the non-GPT system partition (eg. F: Drive)
Right click --> Shrink the disk and put shrink value to 600MB ->OK
Continue with above mbr2gpt commands

ERROR2
If there is a "failed to update reagent.xml" error, this is just an
error finding the recovery partition (doesn't affect boot)
To fix:
-Boot into Windows
-Assign Recovery partition a drive letter temporarily
(admin cmd, diskpart, list disk, select disk #, list partition - to
find which has Type = Recovery)
-assign drive letter to recovery partition
(select partition #, assign)
-check that drive letter is assigned to Recovery partition
-from ANOTHER admin cmd = reagentc /setreimage /path F:\Recovery\WindowsRE
...Directory set to....
...REAGENTC.EXE operation successfull...

-reagentc /enable
...winre activating (or something)
-close this admin CMD prompt but leave the diskpart one alone
"reagentc /info" to check information on the recovery environment variables

Remove drive letter from recovery partition
-go back to diskpart and make sure it is still on the same partition
(if so, just type "remove" and hit enter to remove the assigned drive letter)

Those are not the only options. OMV is free and works well using the mergerfs and snapraid plug-ins. It can do differently sized drives with no issue, offers parity protection, and can combat bitrot using checksumming. unRaid doesn't (or at least didn't used to) believe in bitrot so didn't offer any real solutions. For TrueNAS you probably want the Scale version.

On Windows, Stablebit DrivePool + snapraid is pretty solid and similar in functionality to OMV with mergerfs and snapraid. DrivePool is a paid product FYI.

You couldn't be more wrong. Figure out a distro that does what you want (including checksumming if you want to combat bit-rot) and then never worry about what drives you put in again. Also, have backups like any sane person who cares about their data. Just because you're dealing with large TB numbers and have high availability protection doesn't mean you can all of a sudden ignore backups. Corruption, malware, and human error are still in play.

You don't want RAID5. Rebuild times will be insane at higher drive sizes and you're probably going to stress another drive to death during that process. RAID5 is no longer a popular option unless people are keeping legacy arrays alive perhaps and don't want to convert.
I would go with parity protection (and do) over RAID5.
Parity information is written to the largest disk (and it must remain so if you're going to protect all data) and any drive failure can be rebuilt simply by your array doing the math to restore data to the missing drive. Easy process.
