Something that's interested me is how hard drive capacities have continuously gone up, but read and write speeds have not really changed. To the point where it would take multiple days to read these new high capacity drives.
I wonder what the use case for them is, they aren't ideal for RAID as they would take far too long to rebuild the array in a drive failure, but they also aren't great for long term cold storage. Perhaps they are ideal for periodic backups where you want to take a daily 1TB backup of a server or CCTV where you don't really care about backing up the data as it's all deleted on schedule anyway.
RAID 5 being too risky doesn't invalidate the whole concept. You can use RAID 6 with two parity drives instead of one, or something higher level like ZFS or Ceph. If you have a trustworthy backup and can tolerate an amount of downtime risk, you can even run RAID 0 or mergerfs on your main array. Many ways to arrange storage.
