Hard disk orientation...

Sorry if this question has already been asked and answered. I did a search of the forum and couldn't really find anything about it.
I was wondering if hard disk orientation plays any role in reliability/longevity of the drive.
"Google" has some very basic and contradictory information, official websites like Seagate and WD simply state "drives can be used in any orientation."
Would like to get some qualified answers/opinions from the HDD guys.
I have a client with an ext HDD enclosure (LaCie) that has the removable drive installed vertically.
This is the third time I've had to replace the HDD in just over 12 months.
Drive installed when purchased was a WD "Black" 2 TB and the second was a WD "Red."
This time I've replaced it with a Seagate 2TB "Ironwolf"
The drives are under warranty so replacements are not a problem, but when they fail they take her data with them.
TIA
 
I have no data to back failure rates on being mounted vertically. But hard drives in Synology's are mounted vertically. My own computer case has no option other than mounting them vertically. I suspect it doesnt play a part.

However, in the case of the LaCie external hard drive, Id say things like heat and 'movement while running' play a greater role.

Yes, I tend to agree with you about the "movement while running!" These people (3 user SoHo office) use it to backup their laptops and just grab it, unplug it and place it on their desk before it even has time to stop spinning! (yeah, yeah, I know I've tried, believe me!)
As for the heat, It has some fairly good ventilation holes in the bottom and sides, but it does get rather warm.
 
I'd say that you need look no further. Sell them a NAS and bolt it down in a cupboard.
They already have a small NAS that backs up daily as well as continual cloud backup. This drive backs up their (dare I say) more important files as a third option. It goes home with one of the employees nightly, so it cops a bit of a pummelling! It's supposed to be for work related only, but I find personal stuff on it all the time!
 
I would agree with what the others have said that hard disk orientation itself would not be an issue with the fail rate of the hard drive. While I can not back this with a study, I do believe that hard disk orientation and how the end user uses or abuses the system itself (kicking the system around, how much ventilation they give the system generating unnecessary heat, etc) would affect the hard drive and most of the components life cycle.

They say it doesnt but i dunno, vertical has better heat dissipation right? i mean when compared to horizontal in a configuration where the hard drives are right next to each other.

For over 20 years I've installed racks and racks of servers of both drive orientations. Since servers are designed to run as trouble free as possible, 24x7x365, I would have faith in their designers knowing that "It doesn't matter if the drives are vertical or horizontal". Compaq/HP Proliants, Dell PowerEdges, IBM/Lenovo ThinkServers, SuperMicros, Synology NAS's....all the top brands do both.

If I had to think deep about it from an engineering and physics standpoint and make a choice, I'd wager that vertical has less wear and tear. But...the industry has proven it doesn't matter.

I have seen hard drives mounted topside-up and or horizontally including in servers and SAS drivers too. Never seen it to make a difference. Have her backup.
 
I suspect what they're not telling you is how many times the drive has been dropped, tossed onto a desk or into a drawer, etc. Three different hard drives just don't fail like that without some sort of physical abuse.

Agreed - That's what the engineer in me is saying. But, if they say it doesn't matter then why do some old drives fail or scream when you turn them 90°? (I used to love to pull the old big heavy 2TB drives out of the dock after they parked their heads but were still spinning. The gyroscopic forces were very pronounced.)

I think the answer to that one is easy..."the bearings aren't used to a different axis"....they evenly wear in a certain axis over time. Change it..and they need a few years to settle into that axis.
 
Understood and the same that I concluded after I posted. But, I've had three drives scream/struggle (ever) when they went from flat to vertical in the dock. I've never had a drive care about going vertical to flat but my sample selection is small.

Back to the original question. I wouldn't think it's the drive type or orientation but that the unit is mobile.

I have difficulty believing anyone could move an external drive or laptop about without rotating it about anything but its current axis of rotation. It's not impossible, just highly improbable, IMO. Given that the heads are floating just nano-meters above the rotating platters, it doesn't take much of a bump or deflection of the head gimbals before much damage is done. If the heads are parked in the ramp, it's less of an issue, or course, but still not risk-free.

Moving the drive about and especially when the drive is still spinning is just asking for a failure.
I have seen them do this on many occasions despite my protestations about damaging it!
They're in a hurry to get out of the office so they grab the box, yank the cords without going through the "safely remove" routine and just plonk it down on another desk....:rolleyes:

Thanks all.
... both Seagate and WD say that "drives can be used in any orientation" so I think I have my answer. The abuse the drive (or more specifically) the whole unit gets from rough handling is the major issue.
Even though Seagate and WD replace them without question and I charge a good chunk for "fixing it" I still need to get the point across to them. The data they contain is backed up to NAS and cloud also, so it's not a door closing issue. The only tears are from the loss of the "private data" that's not supposed to be on it anyway!

Well, you can't fix – or educate, apparently – stupid, so just increase your chunk by 15% every time. They just don't deserve nice things. Let's hope Seagate and WD aren't tracking your failure rate.
