Wd 10k vs samsung 849

Just ordered 2x samsung 840 1tb and 2x seagate thunderbolt adapters and now I'm maybe getting cold feet. I heard the wd 2tb 10k velocoraptor was more than suitable for my needs and half the price. A buddy of mine who works on drives told me the WD are generally crap, but I understand they use better components in the 10k. I mainly do motion graphics, adobe suite and cinema 4d. Used to do a lot of editing but that's gone by the wayside...any opinions. O and nMP 8,32,512,d500 will be here this week. I hope :)
 
i've been using WD for years (Greens and Reds) without any failing, quite happy with them, not sure why your friend thinks so.
 
I have been using WD VelociRaptor drives in my Mac Pro for the past 4 years and they are terrible in the Mac Pro.

I think the issue isn't the drives, because I have these in a server and that thing runs fine for the past few years.

The Mac Pro, although has great cooling doesn't really cool the very hot VR drives well.

Over the past 4 years, I've had to warranty each drive at least twice for failures. So all the drives in my machine are refurbished warranty units at this point. I also keep a spare ready at all times, and my spare has been warranty exchanged twice.


You want performance? Get SSDs.

Aren't your drives the old, full size 3.5" units though?

haha. I love this sort of stuff. What does your buddy base this informed opinion on?

He's a certified apple tech, he told me he sees more failed WD drives than any other brand. Is that "informed" enough?

Talk to any 'informed' person and they'll all give you completely different answers on what brand of hard drive have the most failures. It's all subjective.

No. His experience and prior observations alone are insufficient to make that judgement.

The way the human brain works, and the way that statistics works are quite different. In many cases our observations lead us to conclusion which seem sound but which are not.

The size of the potential service pool (those systems which have not failed but are similar to those which have) is also important. Imagine that computer models X and Y are in active use. Model X uses A drives and model Y used B drives. If X systems were bought in much larger numbers than Y systems, a service tech would see far more A failures than Bs. This would be expected even if B drives failed at much higher rates than did A drives.

Your friend might have additional knowledge or experience which could justify his conclusions. However, in isolation, the relatively frequency of failures he has observed is not sufficient to support a statistically sound conclusion.

Absolutely. I'm a non certified self taught apple and PC engineer for almost 25 years. WD is my preferred brand for the past 5-10 of that. Put it this way, I have far more hitachi and Seagate drives in my graveyard than WD, kept for drive recovery purposes to swap out PCB's for clients failed disks.

My experience with hard drives says it's less platters that matter so for example I shy away from buying HGST with their five platter drives. Too much heat and too many moving parts. Wd greens and reds spin slow, generate less heat and are therefore are more reliable than a 7.2k or a 10k spinner.

Besides unless it's for big data storage spinning disks are off my menu anyway - solid state is the only great if you need speed. If you can afford the pair of 840's go for it - they are superb and will make mincemeat out of any spinner, plus won't sound like a miniature angle grinder if you accidentally knock it ;-)

You sound like you have some other problems. I thought you are here to learn interesting things from other members.

I have been spending a lot of time out of the basement building a shed for my tractor. I hope that counts? :confused:

Perhaps you should, I had plenty of that when I had a full head of hair and no kids and wouldn't have even dreamed about sharing my knowledge on a mac technical forum back then cos the internet didn't exist fella! :D

With the monsoon winter we've had I hope you haven't had a Passchendale moment building that! :D
