alexander-n8hgeg5e,
You have never hear a real HDD with a real stepper motor.
Voice coil activated head servos (any HDD over 1G or so) are so much smoother and quieter than the buzz of a stepper motor.
Lots of long seeks can make a voice coil head servo noisy too.

The oldest thing I had was such a 5.25 " drive with 4Gbyte i think...
But i can't remember if it was loud.
At that time it was already old, don't know why i mounted it
in the computer, i think i was attacted by the size of the case.
It was 40Gbyte best price/value time. , approx.

That are real harddisks  , you can probably read your mails with a
lens and some iron dust...
The new ones are guessing your data, are trying to read from the atoms...
Do you run them in some system that you use ? |

Sounds like a late-model Quantum Bigfoot to me. Pretty common, and the last of the half-height 5.25" drives IIRC.

The 80MB drive was a (mostly r/o) boot drive in my router for many years after the 386 SX16 it belonged to bit the dust (a drive outliving a motherboard, imagine that!). Now it's in my IBM 330-100DX4 retro gaming machine, again as a boot drive, with a Conner 540MB (also loud as f*) for storage.
The 120MB is sitting on a shelf along with a couple of 640MB drives, they're all goers, I just have nothing to put them in right now.

I run ZFS on my storage server, it's wicked cool. Snapshots, checksums, transparent compression, deduplication, network replication, adaptive caching, all the other good stuff.
BTRFS looks promising, but it's still kinda feature-poor next to ZFS.

Just put more of them in the device.
Mix the models good up.
And make raid1's to combine them down.
Then put btrfs raid1 over that.
Btrfs can fix bitflips, if the drives fail to find them.
I have my disks somewhat frankenstein... One disk died young.
One is to small so i have lvm-combined the wd-blue and the wd-black.
So actually 3 x redundancy.
The other 2 are hitachi ultrastar and one is wd-green
I have discovered something,
smartctl -s aam,128 i think makes them quiet.
This should probably help for longer life.
Device Model : WD5000AAKS-00A7B2

Power_On_Hours : 41329
Device Model : WD10EADS-00M2B0
Power_On_Hours : 15960
I know, they draw power, they are slow, and make noise.
But my data is on a real disk, and they do not die if i write
to the same sector a few times. |
You right, that's make sense.
HGST Travelstar

SAMSUNG HM250HI
http://dpaste.com/12CJR7B
Those are old one, the HGST show some failure but still handle)
About seagate, I got a usb drive Seagate RSS LLC Backup Plus Portable Drive for less than a year, never worked too :

Can't get a smart result on this one |

Yes I think it was a quantum bigfoot.

I cannot believe the board died,... These old computers look that reliable,...
Probably the capacitors,... maybe fixable.

But then i recognized , it is not in my loved kernel, and something with the license... |

You've never owned a Quantum Fireball (or Atlas for that matter), have you.

I did, that was my first drive |
