What's your highest "power on hours" HDD?

Sun May 28, 2017 6:08 pm

Current or historic.

I think the highest I currently have is 22K, then a few 20Ks. Not sure about historic ones.

Not a stat I've kept track of but since I run 24/7 (since 2001 in multiple boxen), I just might.

No idea at this point. Pretty sure I've had some go 5+ years. I have a couple of old servers sitting around that had been in operation for a very long time when they finally got retired; if the servers will still spin up without any more effort than punching the power button I'll report back on the POH stats in a bit. You've got me curious too. :wink:

Old web server (just retired recently)

2 500GB SATA drives in a software RAID-1 array:

/dev/sda - WD WD5000AAKS-007AA0 - 55358 hours
/dev/sdb - WD WD5000AAKS-00UU3A0 - 55225 hours

Both drives (and the RAID array) appear to be perfectly healthy. No uncorrectable errors or reallocated sectors. System made some scary noises for a minute or two when I first powered it up, but that's probably one of the fans.

Old file server

Sadly, when I punch the power button it just sits there with the HDD activity light solid on, and never appears on the network. This would've been the more interesting one, since it has more drives in it. Unfortunately, the server is barely accessible physically (I had to reach in past the current file server and piles of crap in the crawlspace just to hit the power button), so I'm somewhat disinclined to dig it out, hook a monitor and keyboard up to it, and figure out why it won't boot.

So these are just the four in my current rig.

WD300 Velociraptor: 44 358 hours
Crucial BX100 500GB - 1596 hours
Seagate 320 GB from two rigs ago - 72 958 hours
WD Green 2tb - 39 107 hours

All but the SSD came from a previous rig (and the Seagate from two rigs ago! Oddly in Crystal Disk Info it's the only one of the mechanical disks not in Caution state due to reallocated sectors.

The WD Green is a bit newer than the veloci because I had a WD Green 750 that ate it

Got an old maxtor/seagate diamondmax 21 320GB drive with 62834 powered on hours, bought 2 of them during a frys sale, I recently broke the other one's power connector :lol:
I still use it as a small supplement to my multi TB drives, smart data looks perfect too, wish the 1TB and 1.5TB Seagate drives I bought had that kind of reliability, one of them did the click of death and the other has a **** of bad sectors.

More stats...

Current File Server

An assortment of drives, the bulk of which are WD Reds and have just over 18000 POH, and two Toshibas with ~12000 POH. All drives still healthy.

Primary Desktop

Couple of Seagate ST3000DM001-1ER166 drives with ~9000 POH, and a WD40EZRZ-00WN9B0 with 5345 POH.

Secondary Desktop

This was my primary desktop until about a year ago. It originally had 2 Seagate 7200.12 or .14 (don't recall which) in a RAID-1 array, which I replaced at some point with newer/larger Toshiba ones after one of them failed. System was powered down after I set up my current desktop, and powered back up recently (but only intermittently) and reformatted to do stuff in Debian (I normally run Ubuntu). Current drives are TOSHIBA DT01ACA200, with ~9000 POH.

Since the old file server isn't emitting any smoke or bad noises, I'll leave it powered on for a while to see if it eventually manages to time out whatever hard drive error is giving it grief, and limp onto the network. If the error isn't in some critical file on the boot drive it should eventually put in an appearance.

Got an old 320GB Seagate drive I bought when my wife and I were dating in late '02. 56,772 hours, which translates to almost 6.5 years of being powered up; it outlasted its direct replacement, one of *those* 1.5TB Seagates, which was fine for several years. Nowadays it's semi-retired as extra/scratch storage on my main computer.

Was still hung as of a minute ago. Gave up and powered it back down.

I think we have a winner!

I'm guessing that most of the drives in my old, retired file server (that wouldn't boot earlier this evening) were around the same as the ones in the web server (~50K hours), or perhaps a bit higher; but I don't think any of them were anywhere near 100K. Drives in my primary desktop builds tend to get used for the life of the build (typically 2-3 years), then relegated to intermittent duty of some sort (e.g. external backup).

Intel 120GB SSD: 21K hours / 18TB NAND writes (over 5 years, at this rate, this thing will outlast me :X ).
WD-Green 2TB: 31K hours / 500K load/unload (yuck)
WD-Red 4TB: 13K hours / 24K load/unload (Fixed overzealous head parking with some software shortly after I bought it)

I have a Bigfoot XT that's well over 130K hours. It was on for a decade and a half or so, and it still powers up just fine. It predates SMART, though, so I have no real proof.

None of the other drives come close, but many of the drives in my NAS are far north of 40K hours (5 years or so).


If I could grab the stats I think the drives in the SGI Indigo^2 from work would win. I retired it a year ago, but it ran 24/7 from 1994 until 2016. That would be...192720 hours of power on time, give or take a few thousand. I could dig up the original purchase order if I was sufficiently motivated, but it was a monster that wouldn't stop working. It took considerable zeal to get the sysadmin to let it go for a Dell R420.

Lot of those No's make mine look relatively new-Oldest-Samsung 103SJ-31017 hours.Approx 7 years old.

Reason I posted was to mention a anomaly I've noticed with a USB 2-1/2" drive.
Drive is a WD-Elements 750GB that's several years old.
Drive has been connected to a set top box to record rugby for at least 5 years.
Basic math-9 hours week for say 26 weeks by 5 years=1170 hours.
Crystal disc gives usage at 22 hours.
My best guess is 22 hours is probably the time connected to PC to transfer files,
and time connected to set top box not logged.

Mentioned this to a friend who was buying some portable drives off e-bay with "low usage"
could be a bit of a trap......................................................................

The only proper drive I currently own (Sandisk X300) is at 9023. The SSD before it (Crucial MX100) probably got to at least twice that, but started bitrotting stuff. I broke it in half when it did that, so I can't really check. Before that was an Intel 320 that is still in use elsewhere and is probably over 30k (it spent a while on server duty). I'll have to check that one when I get a chance.

Somehow, my brother's OS drive is a 128GB Toshiba SSD with 34145. I know that thing has had an unimpressive average duty cycle in the couple years he's been using it, and IIRC it wasn't even installed in anything for the year or two before that, so it must be pretty ancient as SSDs go.

I'd like to chime in. My longest power on hour (currently) is on a WD3200AAKS (320GB) with a power on hour of 34,673 hours from 2007-now I believe.

Hitachi Ultrastar nearline SAS (7200RPM); I Purchased a DAS enclosure with 24 of them in back in 2005 and I only changed half around a dozen drives in that thing over its lifespan, so some of them have to be the originals still.

Despite no longer being production storage, that enclosure has been in use as a D2D backup staging area ever since, so I'm pretty sure those drives are permanently powered, even if they're not constantly spun up. The only downtime in the last twelve years would be measured in hours due to relocation of the hardware.

Consumer drives?
My WD reds in my NAS are on 24/7 but I don't tend to keep them around for more than half a decade for capacity/reliability reasons.

Nice! My limited experience with Enterprise drives was disappointing, but the sample size was too small to say much.

Check the raw value. Maybe CrystalDiskInfo decided that drive reports minutes instead of hours. 22*60 = 1320.
BTW, I wonder how drives log partial-hours when they're powered down.

That load/unload seems fishy. Maybe the raw value means something else, or needs interpretation. Or maybe it's not what I expect "load/unload" to mean. :)

It's a known issue with some of the WD Green models. As a power saving measure, the head unload timeout is set ridiculously low (like 8 seconds IIRC). If your system tends to touch the drive frequently (but not frequently enough to prevent the unload timeout from kicking in) you end up with a ridiculous number of head load/unload cycles.

If your system "touches" the affected drive once a minute you'll end up with 500K load/unload cycles in about a year.

I have a Samsung/Seagate (post-takeover, not sure what's written physically on it) Spinpoint M8 2.5" that shows 420K load/unload (0xE1) after 17K hours.
The normalized value for it is 59, started at 100, with a threshold of 0.

I'll have to check what other drives show here.

I have a couple of greens that I set the idle timeout with wdidle3 to the highest value. The load cycle count on one that was probably downloading torrents climbed to 620k before I rectified the situation. Drive still seems good.

My two 500gb WD blues are at 48k and 62k hours, two 1gb greens at 46k and 34k, two 2gb greens at only around 4k hours. The new greens have load/unload cycles under 100 so far, I did the wdidle fix right away.

Workload seems to matter a lot more than raw hours in my experience.

Treat the drives nicely (streaming reads/writes only, not much seeking) and they'll last for a very long time. Hit them with 4K random and they'll wear out in a few years.

:lol: It's a loud beast. It sat idling forever without anyone touching it...just running along with zero workload. I'm not sure anyone even used it for a few years, but it remained powered up. Skifree still played well when I dismantled the case.

Same here.
Had the WD20EARS for a couple of years and only noticed the Idle3 problem when I bought my WD40EFRX.
I set the timer to 300s on both drives after that.

According to WD, their drives are certified to endure 1M+ load/unload cycles, so despite the rather scary number, we should be fine for many years to come.

Nice, that edges out the 67,510 hours (7.7 years) of my Seagate 320GB that I still use for a scratch disk. I'll drag movies onto it for smooth playback or just unpack files onto it to save the SSD some wear. Those Seagate 320 drives really lasted.
