Will your hard drive last longer if you enable sleep or not?

I’m not sure whether it’s a good or bad thing to allow my Mybooklive to sleep or not.  I’m actually curious about this not only for my MBL but the network attached external hard drive I backup my MBL to.

My mybooklive backs up to my network attached hard drive only once a day.  Besides that, I never use that external hard drive.

My mybooklive is not accessed all that often - maybe 3 times a week for a couple hours each time.  However, I do backup about 4 cell phones to it using mycloud.

Yes.

The drive should not wear as much since the unit won’t be running all the time.
