I've got a machine with data stored on two 3TB disks formatted with
btrfs in a raid1 configuration.  Machine is used as a desktop, home
server and does a bit of data crunching periodically with a mariadb
installation.  One disk is showing signs of failure.  I'm not a gamer
but my usage is probably not quite typical  for a home user.

Yes, I am aware of backing up - so we can avoid that discussion.

Given that I have approximately 700GB free on the filesystem I don't
need to go for a disk larger than 3TB, and owing to raid1 I would not
utilise it until I added a further disk to the raid1 array or replace
the other disk with a larger one.

So I'm wondering which one of the three options below is best:

1. Get any cheap 3TB desktop disk.

2. Get a NAS disk intended for 24x7 such as a WD Red.

3. Frighten my wallet and get an enterprise disk at twice the price of
option 1.

Whatever I do it will be paired for now with a desktop or possibly ex
usb enclosure hdd until that disk expires or is redundant.

Thoughts?

Pete
