Hard Drive Use Cases

So, my friend didn’t have the need for a 2TB external hard drive, and he gifted it to me. The drive was used with a Mac Mini, and was pretty much never turned off after it came out of the box. This is what the SMART statistics came out with:

OhhBarracuda

It turns out that its a Seagate Barracuda Green (hence the 5900 RPM spindle speed). The drive has over 5 years of Total Power On Hours! That’s 44,500 hours – by far and away the most I’ve seen on a drive personally.

I compared it to my Western Digital Caviar Blue 500GB:

WD500

As you can see, it only has 7777 hours on it, but has been started and stopped over 2,300 times, compared to just 150 for the Seagate. My question is: what is worse? Continuous power-on or heavily repeated start-stop cycles? Hmm.

I’ll keep an eye on these drives – this could turn out to be interesting! Stay tuned…
