LifeTime(Hours) apparently rolled over on a couple of my drives. One of them has about 12 years and five months on the Head_Flying_Hours counter, so at least that.

I have two WD Red 3TB with 109.858h and a Samsung SSD 830 256GB with 110.639h on my main workstation (which I built in 2011). That's 12½ years and some extra hours uptime. They are all three fine and still in use.

Power_On_Hours_and_Msec 0x0032 000 100 000 Old_age Always - 46892h+00m+00.000s

some of my higher ones... ~6 years continous

I just hope you've got backups 🙂

Seriously though, we found an old Dell server at work that hadn't been rebooted for years.

We knew that it was fine whilst it was running, but the stress of a reboot would finish it off with all those POST fan speed tests, RAID array tests, etc.

We took as much data off it that we thought might be relevant and rebooted it.

1 drive failed immediately. 1 fan must've had all the dust as that blew out a cloud during the fullspeed test.

A few days later more drives started failing and it just gradually died.

It was actually a sad day when we powered it off for the last time. 🥲

I just had to replace a 4tb drive with a mfgyr of 2016 from a customer's Synology box.

I couldn't get SMART data off it because it wouldn't initialize to do a test, but the thing was damn reliable right up until it went kaput.

About a decade ago, I did some contract work for a local credit union upgrading some of their systems and one of their secondary servers had an old Maxtor drive that had over 31 years of uptime on it. It was wild because at the time, that drive had been running constantly longer than I had been alive.

About the only thing I have in that range would be an old Connor CP30174E from the 90's. It doesn't get any use tho. I framed in in a shadow box for display along with some other drives that I disassembled and display as a curio. I just think they're neat.

I don't understand this whole thing about years of uptime. Don't you ever get system/security/kernel updates that require a reboot?

No screenshots, but I had an old server with a pair of mirrored 8GB Seagates hosting a particularly specialized service on a very beefy and regularly maintained UPS and it had a server uptime of 21 years (had not been rebooted since somewhere around 1999) when I finally decommissioned it about 5 years ago, both disks would've been the same. It was on the public internet the whole time too, running Debian Slink with kernel 2.0.36, which had been awkwardly patched and rebuilt somehow to make the service (itself already obsolete at that time) actually work. I don't know why I remember all this, but I do.

I do remember monitoring the SMART status at various points and the drive bearings must've been pretty cooked because those two drives were always running at 50-60C and I had a big old box fan pointed at the thing with the side panel off.

This example is also why I don't always buy into the cult of "you must always regularly update all software immediately all the time". Old software is not always bad software, same with old hardware. Sometimes it's genuinely possible to have a bulletproof system. The problem is you never really know you do, until it either enters survivorship bias or becomes catastrophically proven otherwise. But you can make educated guesses, and if you're going to naively assume that your old software must have exploitable security holes it seems equally naive to me to assume that updates must never have exploitable security holes. I think the risk calculus has to be done on a case-by-case basis.

These are running ZFS and I have 2 other boxes with similar, most in the 10-12 year range. Spinning drives.

Good stuff.

I've got 12 years and 5 months on a Western Digital WD20EARX HDD. It's starting to get some bad sectors.

I've got a similar runtime on a SAMSUNG SpinPoint F2 and it still seems to be healthy. There's nothing important on either of them, I just want to see how long they will last.

Most of these drives served on Windows Server bare metal w/ StableBit DrivePool + SnapRAID before migrating to Proxmox mergerfs + SnapRAID & ZFS. My raidz1 pool has a combine total of 36+ years lol. Yes I do have backups. :)
