I’d think any NAS or Surveillance drive would be fine, but SSDs are the way to go for reads
Data Hoarder
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
Get an enterprise class hdd, externals aren’t meant to be ran 24/7. Any brand.
I used a 4 TB WD Green for 3 years of torrenting and no trouble. Now it's my security camera HDD as well as some other duplicate storage.
I've been using a refurbished enterprise drive from serverpartdeals.com for about a year and it's still going strong. Plus side: cheap. Downside: refurb.
Since it's torrents I assume it's not critical data, so it shouldn't be too big a deal if the drive fails. Buy two and put them in RAID0¹ if it's actually important.
¹ yeah yeah RAID is not a backup service
Seeding will wear out any HDD quickly. Use a SSD instead.
Sequential access is where HDDs shine.
Random access is where SSDs shine.
Do would surveliance hdd perform better?
No those would be worse, they are designed to sequentially write and almost never read.
Would be worse.
How storage do you need?
Look for enterprise or NAS grade drives. Really no matter which brand, just look for the best $/TB ratio.
I need to look ₹ / TB
Whatever, just use instead of $ your local currency...
