Actually I shared my experienced to kinda say that all harddisk will develop issues regardless of brand but I should add some context. My current setup is a 16 bay Synology with 15x Seagate Ironwolf Pro and 1 x Seagate Exos for backup.
I've tried WD Reds previously and both develop I/O errors after awhile (Bad sectors are not as bad as I/O errors in my view) so have shunned from WD. But Hitachi drives I've used (x2) were problem free but low capacity drives 4TB drives.
In total of running various setups I probably gone thru about 35 - 40 Seagate drives ranging from 4TB/6TB to 10TB/16TB. So far with Seagate a handful will developed bad sectors.
Generally the 4TB Seagate's (Seagate NAS model) are okay though, at one point I had 10 x 4TB Seagate NAS running for about 4 -5 years and only 1 developed a bad sector issue in the late stages before I migrated the volume. They now renamed the NAS model to Ironwolf.
I typically go for the NAS recommended drives which for WD was the WD red hence didn't consider the WD blacks.
So what would be the way to go?
Buy cheaper harddisk and hope for the best?
Buy more expensive harddisk which has better chance to last longer without problem?
So far, all the WD Blacks that I bought have proven to be good. Seagate gave me the worst experience. The previous batch of Seagate I bought ALL RMA-ed. The only lucky thing is that I just need to drop it off in Changi South, which is less than 10mins drive from my place.
