How reliable are Seagate / WD / Hitachi Laptop Hard disks ?

I was wondering if anyone has a reliability/failure chart of these major hard disk vendors ???

 

There's no one brand that's more reliable than another brand - some hard drives by one manufacturer are more reliable than others by another manufacturer, while other drives by that manufacturer may be more prone to failure.

In general though, there's very little variation in failure rates among most equivalent HDDs, so just buy the HDD you want/need/can afford.

 

of the 2 seagate momentus drives i've bought, both have given me some sort of grievance

but like teh above poster, i'm sure the issue rates are comparable with any brand

 

Ive bought 4+ of WD harddrives [Laptops, Desktops, PS3] i never had a problem with them. I only killed 1 out of the 4+ because i did something REALLY dumb to it and it fried.

 

Storagereview.com used to have a reliability database, I'm not sure if they still do.

Newegg's rating system can be used as an indication. Last time we had this discussion Seagate 7200.4 was rated 3.6 stars, Hitachi 7K500 got 4.4. It's by no means scientific but it can say something.

Where do you base this on?

 

It's not a scientific analysis, but I've had a Seagate 320GB @ 7200rpm (Forgot the model), WD Black 3200BEKT, Hitachi 7k500, and a 1TB and 2TB WD desktop Green drives. None have given me issues.

In any case, all/most other things being equal, I'd prefer WD, then Hitachi, and then Seagate. I have no experience with Samsung.

 

I have a 1.5TB External Samsung Station Drive,and I never had any issues yet.Samsung should be reliable in my opinion.I have never seen a person complaining about Samsung devices/hdd's/laptops.Almost every hdd is same,you know,the structure.There is disk(s) on a box inside,there is a motor,and there is a metal that reads that data.You can not figure out which one is more reliable,it is all about luck and usage.

 

In general they all seem to have their strong and weak devices. you have to just lok at some reviews to stay away from the weak items.

My only example so far is the Momentus XT. These use the same platters as the 7200.4. While I have a 7200.4 that is great, the momentus XT suffered high vibration. Enough so the device didn't function properly.

I think they just used a variant of the 5400 RPM platters without tightening the weight tolerances enough. It is like a car with slightly off ballance tires that may drive fine at 55 MPH but be a real beast at 75 MPH.

So as anything else in this world YMMV. With HDD tech it is luck of the draw and just purchase on capacity and performance that you can afford. Now SSD's are a whole other story.......

 

I've never had any problems with Seagate or Toshiba drives. Only recently got my 750gb Western Digital so can't comment on its reliability.
