I own several external 2.5'' HDDs on the 1 TB range where I save my data. Samsung has worked well for me, but now I need more space.
One option would be to buy an external SSD instead of HDD.
Another would be to get an external NVME, but so far I haven't found cases for them.
Nowadays we even have 1 TB flash drives, should I get one of these instead?
I could also buy 2 0.5 TB micro SD cards instead.
So many options make it difficult to decide.
What brands and technologies do you recommend?
Software is going to be debian based.
WD/SanDisk have completely gone to shit. I’d go with Seagate. I have a bunch of IronWolf Pro drives that have been fast and reliable.
What happened with WD? I've never had a drive from them go bad but I'd like to switch if that's going to change
I have a Seagate Barracuda in my gaming rig and it's making really concerning sounds since the very beginning. Even my 12 years old laptop's drive isn't that bad
You could check out c/datahoarder. They should be able to tell you about brands, reliability, best practices ...
The cheapest you’ll find that is still pretty good for HDDs is serverpartdeals. They have recertified Seagate Exos X22 20TB drives with 2 year warranties for $215. They also offer new drives with the full 5 years, ofc. Exos can be a little loud, as with other enterprise drives. You’ll still need a way to read from it in case you don’t have a spare drive bay, too.
Be careful if you buy a Samsung 8x0 SSD. They have long standing bugs that may cause data loss. They are worked around in the kernel, however you have to ensure that the workaround for your particular model exists in the kernel version you use.
