<p class="MsoNormal"><br>
Weird question:<br>
<br>
I can get a bunch of ancient (~2013) HDDs. Each have varying amounts of space, and few (if any) are ever the same size.<br>
<br>
These were marked to be disposed, though that is just because of age or having plenty that are better. Thus I can take them. However, them being this old, and having found about 3 that eventually broke or never worked, I'm left with this question:<br>
<br>
Because purchasing new drives takes too long (no idea when/if they would arrive), I can take as many of the decommissioned drives I'd like. Seeing as some failed, how does one build a system that is resilient to drives failing?<br>
<br>
It can be reset as much as wanted, hardware is literally in arm's reach, and there is not burning need for it to be up immediately.<br>
There is also massive (comparatively) external drive space and as many live boot USBs as one might desire.<br>
<br>
So how would one build a system that is designed expecting HDD failure regularly?<u></u><u></u></p>
