Seagate Exos X20 hard drives have a cache of 256 MB and they're using Conventional Magnetic Recording (CMR).

You are technically correct, best kind of correct. But you missed this: > It certainly seems that way. Earlier this year I was looking for internal 2.5" HDDs with more than 1TB of capacity, and I could only find Seagate drives.

  I didn't miss it, I was under the impression that the discussion steered to all kinds of hard-disks. I don't think you can install into a laptop the previously mentioned WD Red and Seagate IronWolf :-) By the way, I'm shocked that someone would put a SMR HDD into a laptop. Most laptops already had slow disks when CMR was used, but with SMR, I don't even want to think of the results.

Fair assumption. > [...] laptop [...] If you said this because of any message from me, then I probably should have given more context. This was for a desktop PC upgrade, in a Corsair 5000D case. The OS (FreeBSD), user files, and almost everything is in M.2 (two of them, in a ZFS mirror). I just wanted a mechanical drive where I could send ZFS snapshots, local git mirrors, and some other rarely-read rarely-overwritten files (stuff like also videos/epubs/etc that I occasionally serve over HTTP). The purpose is just having as much storage as cheap as possible, and more conveniently than an external USB HDD (which I also have and use for backups, but I don't want to keep it connected to the PC). The initial plan was to use 3.5" HDDs because the 5000D case technically supports them, but while actually building it and saw the PSU cables my noob lazy self thought how much of a PITA it would be to actually use 3.5" HDDs (or how ugly it would look if I put them in a different place than intended). So the plan changed to using the 2.5" mounts, and here I am now. I'm currently working on building a NAS (separate from this Corsair 5000D desktop build), so soon-ish I should be able to just use that NAS for these files, and use the free 2.5" mounts for SSDs to increase the system ZFS pool. Hopefully this additional context clarifies things.
