AWS does not re-use disks under any circumstance. It is strictly forbidden to protect customer data. Disks also do not leave the datacenter until they have been degaussed AND crushed.

Here is a Glacier S3 rack:

10Gbe TOR

3 x Servers

2 x 4U Jbod per server that contains around 90 disks or so

Disks are WD Green 4TB.

Roughly 2 PB of raw disk capacity per rack

The magic as with all AWS stuff is in the software.
