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.

Options for 2.5" SATA CMR spinning drive in 2023? (alien.top)

I'm looking for non-shingled spinning 2.5" SATA drives

  • due to data storage policies, it must NOT be a SSD but a spinning drive
  • due to the use of ZFS, it can't be a SMR
  • 1Tb or more (2Tb would be nice)
  • ideally 9.5 mm or thinner (7mm would be preferred for a better airflow, 15 mm would require a 3d-printed cover)
  • ideally new (new-old stock and used drives would require a few days of testing to validate the SMART info and the absence of bad sectors)

I've heard the WD Blue 2.5" and the Seagate Exos might be valid options:

If you know about other options, could you please list them?

Seagate Backup Plus Slim & Backup Plus Fast USB drives from a few years back are shuckable and have 1TB or 2TB Seagate 2.5" drives in them from pre-shingled days. Fast is 4TB (2×2TB in RAID-0). I have shucked a number of the 2TB and they contained Seagate ST2000LM003 drives. Not sure but I believe these are all 5400 rpm. You may be able to find some new.

I am also a fan of the HGST Travelstar 7K1000 which is a 1TB 7200 rpm drive. Bought those as bare drives and they performed well.

Personally, my opinion is that whatever policy is mandating 2.5" hard drives which are no longer being made is simply outdated and uninformed. Find some reputable 4TB/8TB 2.5" SATA SSDs with high endurance ratings and implement a backup requirement. Samsung, Intel, Micron... go with enterprise drives if desired.

I thought I hit the jackpot as I have a few, but I've just read in a reply below they ARE SMR as I suspected

HGST Travelstar 7K1000

I will look for them immediately

Some of these systems are left powered off for years, so requiring HDD next to NAND seems reasonable to mitigate the risks of data loss.
