If you needed it, you'd be using it.
I wrote a test program where I duplicated (not ported) a portion of my 2-D geometry library in C#. Test consisted of finding all the intersections in a list 100,000 arbitrary polygons of between 7 and 15 corners.
My first run came in at 7 times slower than my C++ code. After reading about optimization techniques and doing my own tuning, I got it down to 2.5 times slower and was actually quite impressed. The problem was the tuning and optimizations made the code look like crap and any potential structural benefits went right out the window.
Bottom line is, CLR is not great for finding polygonal intersections, but it does a bang-up job on many things I don't need.
Use the tools for the job.

I have one of those Popcorn Hour network media tanks [^]on order and I see it supports up to 2TB SATA hard drive so I'm scoping out the 1TB ones and the prices are very surprisingly reasonable, in some cases as low as US$150.00, i.e. less than double the price of a 500gb. I'm planning on using it as a NAS as well.
Trouble is I came across all sorts of conflicting info on Seagate vs Western Digital vs what have you.
Anyone have any personal experience with any of these SATA 1TB drives?
[EDIT]After reading this and particularly the post from JazzJackRabbit I did some more digging and found what appears to be the perfect 1TB drive for a network media device: http://www.westerndigital.com/en/products/products.asp?driveid=388&language=en[^] It's 1TB and optimized for low sound, low heat, low power consumption and for streaming video and audio files.

I am running two of them at home, just ordered a third for the wife. Running about a dozen external USB versions of them at work. What do you want to know?

I hear conflicting info on reliablity between the major brands, wondering if anyone has had reliability problems with any particular brand and I guess I could toss in did they seem to run unusually hot.

In the last 12 years I have had problems with Quantum, IBM, Maxtor, WDC, and Seagate. When I see an increase in failure rate from a manufacturer I just select a different brand for the next few years..

all my drives run hot, for the last 2 years I cool all drives. That has become more and more the norm. From 15k rpm drives at work, to 10k rpm drives to 7200.11 drives, they run hot. Anymore I have dropped all but seagate. Work only buys seagate. Every failed seagate drive we have had can be traced to physical damage, not age. 5 year warranties are hard to beat. I have replaced all but 2 WD I have ever owned, half of all WD's I have had have failed on me. I just stopped. The only surviving ones are the 10k raptors, go figure.
I cool everything from CPU to memory to drives. I don't over clock, but I cool as if I were going to.

I prefer Seagate 7200.11 drives since they have a 5 year warranty. I have over 100 7200.10 and 7200.11 drives at work for that very reason.

Except for the 5 DOA ones I have returned 1 or 2 in the last 3 years. I attribute most of the DOA problems from neweggs packaging though. Sometimes they will put a drives in a box with just peanuts around them but most times they will do the right thing and bubble wrap each individual drive.

i dont know about the 1TB drives...
but from my personal experience i wont trust anything other that a seagate drive. Ive never come across a dead one (and i have old 500mb , 1gig and 2gig drives by the crate load) or had any troubles with them.
I have how ever had Western Digital drives die on me, controller boards overheating and blowing for no apparent reason.
I heard that Western Digital got bought by Seagate, so the quality of their drives might have changed but i wouldn't take that chance.
So my vote goes to Seagate

Yes, I did. And as it invariably does, a second after I'd hit submit!

Equipped with 8 MB cache buffer for improved performance
Hmm. If that is true it means the drive is probably 2 to 3 years old since no company makes drives with only 8MB buffers anymore. 32 MB is the new standard...
[EDIT]it looks like they still make a few 8MB models.[/EDIT]

I guess, it serves me right for being too lazy to research the thing out enough! The "Tech Specs" tab on that site says the buffer size is 16 MB though.

That sounds better. I guess the documentation was just old.. Although it appears a few of these 8 MB drives still exist..

Maxtor got bought by Seagate. What it did to the quality of both brands is hard to say.
Western Digital is still a separate entity.

oops, your right! i got it mixed up a bit

agreed, which is why i wouldnt take the chance of putting a MAXTOR in my box
for the record ive had issues with WD aswell as maxtor...

Seagate made a bad batch for MacBook and MacBook Pros a year or so again. Mine died horribly and so did my girlfriend's.

Ditto on the Seagate. Been using them for a long time, and never had any data loss. The 7200.11 drives are also great performers. Check out Tom's Hardware charts for some benchmarks.

I would suggest WD GP 1TB drives. They spin at 5400 RPM which means they run very cool to the point where they don't need active cooling and they run quiet, yet they are still fast enough to do everything except most demanding tasks.
Whatever you decide, stay away from Samsung 1TB drives. Samsung made some excellent drives in the past such as 2504C, HD321KJ and 500 series, but there are some questions about their F1 drives reliability.
Most of the Hitachi 1TB drives use 5 platters which means very high heat and very high noise. As far as I know Hitachi drives also support dynamic speed control, meaning drives slows down from nominal 7200RPM speed to conserve energy and lower noise, which is certainly nice, but I still wouldn't buy them. The newest Hitachi drives that have been recently announced (I think it's called 7K1000.B) have only 3 platters, but I'm not sure you can buy those yet.
As far as I know all current Seagate 1TB drives have four platters. Which makes them middle of the road between F1 and Hitachi.
Currently WD offers more choices than anybody else, it has 7200RPM four platter 1TB drives as well as 4 platter (3 platters in the newest revision) 5400RPM drives, along with the usual plethora of "enterprise" or "black" edition hard drives.
Anyway, it looks like you're looking for a media/backup drive, for which WD GP 1TB drive would be a perfect solution. They are quiet, cool running and pretty fast, especially latest 00D6B0 revision which only has 3 platters instead of original 4.

Nice post! Exactly what I was looking for. Coolness appears to be an important factor and ultimate speed isn't so this is very likely the way I'll go.
Thanks for the information.
