6 of one, a half dozen of the other.
If you're doing drive imaging backups of something like a system drive under Windows, I'd recommend Macrium Reflect.
If you're just doing a basic sync, I like FreeFileSync personally.
If you can, I like to buy slightly different models or try to buy from a different vendor to differentiate model numbers or at least HDD batch numbers. Just in case a firmware bug or some other unexpected flaw for that particular model or batch eats one of my drives. At least the other one (or other set) will likely survive. Just a thought.
Also don't forget to do a full surface test, which will likely take more than a day at these drive sizes. You can use something as simple as WD Data Lifeguard for this.

do they always replace with refurbs?
This is my back up
1 Synology 8 Bay +2 expansions at 20TB per drive at Raid 6 or synology equivalent. SHR-2 64GB ram around 300TB (off site) parents house
4 smaller nas
1 synology 8 BAY SHR-2 12TB each drive = 65.5TB
1 Synology 8 Bay SHR-2 16TB each drive = around 76.4TB
1 Synology 4 Bay (legacy) 14TB each drive = SHR1 or raid 5 = 38.2
1 2 Bay ( 18TB raid 1 (mirror) = backing to the remote NAS = 18TB
so not to brag but i back them up to the remote NAS ( if this not back up proof :/ i don't know what else is
NAS could be a solid back up solution.

By the way, the two 10Tb drives that I got had 5.5 years worth of 24/7 hours on them according to the CrystalDiskInfo utility program.
That means that they have another about 280 years to go before MTBF.
(These drives are rated at 2.5 million hours MBTF, or about 285 years of 24/7 operation.)
The 10Tb drives I got are amazingly quiet, better than some consumer drives.
That doesn't mean that they may not fail before that, but it indicates that they're pretty good hard drives.
Should be kept in an active ventilation enclosure/PC case, that means cooling fan(s).
A standard NTFS format of the 10Tb disks takes overnight and the drive gets pretty warm.
Same if one runs the command prompt check disk command for bad sectors/clusters: chkdsk X: /f /r /b (X is the drive letter in your computer)
Best to do these two operations when you get the drive(s).
Anyone who follows SD enterprise HDD threads knows the approximate pricing. You're quite obviously getting a refurb for under $100.
And more importantly, this is not the first or the last time someone has accidentally omitted a tag in a title. My primary issue, and the reason I responded in the first place, was that someone said they WOULDN'T BUY THIS because it was a used/refurb drive at that price.
This IS the good price for a refurb enterprise drive, as evidenced by it going Frontpage. There is no better deal currently.
I don't think any of us will dissuade folks who are hesitant but math-wise if you have a good protection/redundancy plan your data will survive a drive(s) failure.
I'm already doing high availability (parity) and separate backups so I'll take the discount on a drive that likely has more life in it.
Every drive will die, you have to plan for the worst if you care at all about your data. If you're NOT planning for the worst, that says more about your contempt for the data you're storing than anything else. Drives are gonna do what they do regardless.

If you were buying from a random on ebay or Walmart marketplace or something..... that's a different kettle of fish.
So I agree with you, but the SD vendor choices are pretty static on these particular types of drives.
So, learn the lesson, and RAID is not considered a backup.
If one of my drives fail, I smile and say to myself , "I was told many times to make backups and I'm glad I listened, ... thank God".

1) i use 4 x 2TB portable external drives..(keeping the same copy of data on two different drives manually)
2) recently bought a 14Tb Seagate expansion drive from Bestbuy which I am keeping as a Master Copy of All data
I don't know if keeping multiple copies manually will help me, or is there something I could do better in budget?
please someone give me any budget idea's I could build it myself?
