We had been buying WD drives for years. But after flooding ran drive prices up, Seagate was the first to have prices become a bit more reasonable, so as you can see we bought four Seagate drives.

Withing two weeks of each other the WD 3 TB failed, and one of the Seagate drives died outright. Testing of the other three Seagate drives showed abnormal error rates.

So I bit the bullet and bought Hitachi drives and junked the Seagate drives, at a cost of nearly a grand and hundreds of n=man hours making the switch.

That kind of thing only happens once with a vendor, and they are toast. So while Seagate was the primary cause to switch vendors, I tossed WD because their drives are less reliable than Hitachi and because the WD drive should not have failed that soon.

The issue is reliability and not losing data. The combination of the two drives failing so close to each other cost me data, and about $30,000 to recreate just part of the lost data.

From then on Seagate would never sell us another drive. They make unreliable junk.

You’re an idiot Richard….a classless troll with no manners. Your parents obviously taught you well. People like you need to shut your mouth and stay off the Internet and get a real hobby that involves getting out of your mom’s basement.

Now that I read your reports, my legs are shaking as I use my Baraccudas to store my most valuable data. Now that I think about it, 2 of 4 of my ST2000M001s have died and at least one WD 2TB died (died yesterday). None of the IBM/Hitachis have ever died on me. Three of the 8+ years old 1TB IBM Deskstar drives are still running 18 hours a day. I am now writing this on the subway heading to the computer store to buy HGST drives to replace the Baraccudas and WDs. Thanks for the extremely useful reports.

You fail harder than Seagate.

You can get that off the SMART data that they publish on their Hard Drive Data page! Go… analyze it for us!

I have a 2TB WD Green sitting in my cupboard at the moment and it still works to this very day. And i’m also surprised that a 18yr old HDD is still working and it’s a Maxtor the one that is a failure.

Also ripped from another computer was a Seagate was a 1 and a half year HDD, but it was also too dead. My most trusted brands are WD, Smasung and Hitachi. Wouldn’t mind Hitachi or Fujitsu, but they’re getting way past my curfew, so now it’s time to pull out my big guns of speed.

I’ve also noticed none of my drives developed faults in them during the course of certain doom with my MOBO and they’re still here by my side working.

I wouldn’t think it’s reliability that causes this. I would possibly think about how much data is on the persons Hard Drive and what they’re using it for (big files can cause the hard drive to wear down over it’s lifetime, therefore making the drive fail would be that it’s being stressed pass it’s limit), but then again Seagate is on the bottom of my list.

But guess what the Xbox One is certain doom for? Yep it’s got a Seagate HDD in it. And is really a bad brand to pick up. After my incident I am lucky to survive and to have 1000’s of dollars of my stuff still here.

This gives me a good gap to sue Seagate for a Safety Hazard with the Hard Drives they make.

My theory might not be correct, but at least some of you understand what i’m saying correct? I wonder what i’m going to do with all the GB’s I have at the moment? I have got at least 4tb of empty space waiting to be filled up with who knows :)

I am going to tell you a very short story:

I had a 32GB USB in tip top condition, but one day it wouldn’t be recognised by Windows. I thought the drive was stuffed and it looked like it. Until I plugged it in to my Linux PC and BAM recognised it straight away.

I would not go out of the 2TB barrier I set upon my self as higher capacities will have higher failure rates. It would seem like i’ve arrived in a modified world of No Man’s Land. If I had the 1TB I had today from a year ago I would’ve been very happy. Alas I dropped it and the click of death overwhelmed me. Simply put I would’ve cracked the enclosure and fixed it myself, but if it happened to the new one I have which I would never do, then come out the gloves and in a clean room I go.

Anyway too much storage is a no for me, except my 2TB HDD. which holds my Naruto and One Piece anime.

More information: Desktop HDDs tend to have a duty cycle of 8 Power On Hours (POH) per
day. Enterprise drives tend to have a duty cycle of 24 POH/day. A lot
of NAS drives are spec’d at 1 POH/day (8760 POH/yr).

Apply these duty cycles to the failure rate of each drive population and adjust for how many actual years you’ve consumed from the drive health.

They should do case temperatures of the drives within the array. Reliability decreases by a factor of two (2) for every 15 degrees the drive is above 25C-30C.
