Hard drive Spin down or not?

Do you guys set the hard drives to spin down after an x amount of minutes?

I always set it to "never" and have good luck with it as I haven't had a drive failure for several years. Now that the number of drives in my server has gone up quite a bit, I'm thinking of setting it to spin down to reduce power consumption.

I'm sure there's some debate whether to spin down or not and how it affects the life cycle of the drives. It's probably better not to get into that debate. I just want to know from real experience if you guys let it spin down or not and what is the average life cycle of your drives?

Do not spin down.
BOOT: 1x 80GB SSD (Intel X25-M G2)
DATA: 4x 1TB (WD10EACS, WD10EACS, WD10EADS, WD10EARS)
Going about 2 years now.

Spindown for power savings, and more importantly, heat. The only real downside I see is anytime a rercording is called up from a spun down drive there is a small delay while it spins up and you get a spinning circle until the drive comes online. Interestingly enough the only hard drive failures I've had in the last few years (knock on wood) have been from a bad batch of Seagates that were used in different systems in very different operating environments.

Most drives today use liquid bearings and are quiet enough and efficient enough to not need spin-down. I personally do not use power saving techniques except shutting the server off during extended non-use periods. If you are looking for extending the longevity of drives your biggest culprit is heat and fluctuating power. So make sure you have enough air-flow to keep the drives relatively cool and that you have a power supply that is of pretty good quality. Using a UPS doesn’t hurt either. Unless you have a traumatic event overheating, jilting the drive while it is running, or power surges, flickers, and brown outs your drive should run fine for many years. Typically my drives are replaced for size issues well before failure.

I don't care much about noise as the server is located in the back room. I rather keep the drives spinning too, but since I have so many drives, 7 and counting, I'm looking to reduce power consumption since the server runs 24/7. And the drives are cooled properly so I can't recall the last drive failure. I replace my drives every 2 or 3 years. I'm gonna set it to spin down after 20 minutes of inactivity and see how it reduces power consumption. Just wanted to get opinions from fellow SageTV users.
