Stuck choosing between 5400 and 7200 RPM drives

Hi guys,

Previously I had Synology clone installed on my HP Microserver equipped with 2x 8TB WD NAS Plus HDDs in RAID 1 mode, which are 5400 RPM drives.

Now, when I’ve decided to go for TrueNAS, I thought maybe it’s a good idea to also upgrade the drives to have more capacity.

But to my surprise WD does not have 5400RPM drives with more capacity than 8TB… 7200 RPM drives are more faster, yes, but I like the fact that 5400 RPM drives are quitter, less power hungry, and more reliable.

So get two more same 8TB 5400 drives or go for 7200 drives anyway?

What’s your thoughts?
