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.
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.
Buy from TrueNAS. They sell hardware.
ASUSTOR has NAS that can have up to 12 NVME SSDs (but speed is very limited by PCIE lanes).
NVME SSDs are still very expensive compares to HDD.
NAS that have many HDD bays are expensive but designed for easy setup and easy management.
Fractal Design Define 7 (XL) can have up to 18 HDDs by design, but then you will need to search for PCIE to SATA cards and PSU that have many SATA connectors (for example RM850x/RM1000x) and Molex to SATA cables.
FSP CMT370 is a much cheaper case with up to 3.5" HDD *9 or 2.5" SSD *10 but it’s not on amazon, it probably doesn’t sell to western world.
SAS drive enclosures (and SAS cards) are also an option, but the cages might be very loud because they are designed for servers that also are very loud.
You could check out c/datahoarder. They should be able to tell you about brands, reliability, best practices …
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.
