Awesome can’t wait til they’re cheap so I can replace my many hard drives with just one much larger one.
Make sure you buy two of them so you’ve got a backup. I’m uncomfortable storing 16TB worth of data on one drive, no way am I putting 32TB of anything I give a shit about onto one drive.
If you have 20TB of data to store, a single drive is safer than splitting it across multiple drives. Few point of failure in total.
If you are storing your own data a single drive is asking to lose all your data.
3 2 1 for all your important data.
This single point of failure equals to putting all of your eggs in the same basket.
If it’s split up sure, but I’m talking about a raid > 0 setup and/or having backup copies of your data onto drive #2
First, if you have more than one disk, you should be either getting redundancy through mirroring, or building arrays of several disks with redundant methods like RAID5 / RAID6 / ZFS zraid2.
Second, no single copy of data is safe, you must always have recent, tested backups.
