How much faster is a 10000rpm than 7200rpm HDD? I know its about 2800rpm faster but what exactly is that in seconds. Im thinking about getting a 74gb raptor but dont know how much faster it would really be. Sound and heat arent problems... just money and if it'll be well spent or not.

Alot of it depends on the conditions. Under some situations, a 7200 RPM 1TB will be faster than a 10000RPM 74GB.
A the 1TB drive will transfer large files faster, while the 74GB will start transfers faster (this results in faster transfer of small files).
The average latency on the Raptor 74GB is 3ms, while the average for the 1TB seagate 7200rpm is 4.16ms. Becuase of this, if a file takes less than 0.005 (aproximately) seconds to transfer, it will transfer faster with the raptor. This seams like it would be of little use, but it can help a lot with operating systems & games, as these typicaly have lots of little files.
[edit]
When used in RAID-0, RAID-5, RAID-6, RAID-50, RAID-10, or any other raid that uses stripes, higher RPM drives make a much more noticable improvement over low RPM drives thanks to the fact that stripes are small (usualy less than 512K).

Depends which 7200 and 10k drive. Any 7200 drive up until 2008 will be substantially beaten by pretty much any 10k drive. However, latter 7200rpm drives like the Samsung F1 and Caviar Black have very high read rates which means for processing large files they are faster than the smaller drives. Since the 37,74 and faster 150GB raptors, however, the Velociraptor has come out, which is still ahead of even the best 7200rpm drives in this department. Something ALL 10k drives do better than 7200 drives regardless, however, is access time. This makes reading large numbers of smaller files faster, the most common example of which is loading an OS (this has an effect in certain games but not many).
In general, I would avoid recommending RAID to anyone who does not have any experience with the technology.

How else might one get experience with raid?

I do not mean first-hand experience, I mean knowledge of how it works, all the drawbacks and risks.

Well, that's a 5400rpm drive designed for low power usage. As it happens, the PC I'm typing to you on uses this exact drive as an OS drive. It runs alright, it's not especially quick but it's perfectly accceptable, it boots XP a hell of a lot quicker than my Raptor boots Vista (though that's because Vista is 32GB in size, and it's only a 37GB drive, so brimmed, and I had to put my page file on a separate drive)

The 74GB Raptors are old and slow by normal comparison. A Velociraptor is your best 10k option, if you don't want one, you may as well buy a Caviar Black instead.

I know their good but compared to 5400rpm... I need some speed. This is gonna be my main computer for everything I do. the caviar blacks are good but wouldnt the old raptor still be faster? The veloci's cost too much and I dont need the whole 150GB of space. 74 would be enough. I saw one for 65$ with shipping

One more question cause Ive been hearing that Raptors sometimes die fast. If my OS is installed on it and it dies, would I have to format my 1TB drive to reinstall my os?

If you keep your HDs cool you should have no problems with quick deaths.
I use HDD health to check up on mine.
It's found here: Panterasoft

I have two Raptors, both several years old, both still working. They can fail (the 150GB ones I think were the most likely) but ultimately, any HDD can fail, it's a risk with any drive.
I don't think you'd see a huge difference between an old raptor and a caviar black, and the Black will make a quarter of the noise.
Contrary to popular belief, heat is not a cause of premature failure of HDDs, it is design flaws and tolerances, and over-cooling. HDDs that run below about 31-32ºC all day are at as much risk of failure as HDDs that are at about 50-51ºC. Go hotter than that and you are indeed at risk, but only original Raptors and Seagates get that hot on their own, without a fan.

I just got a Load of Graduation money
(I just finished High school today =D ) So I have the cash for a New HD, I just dont want a 5400RPM Hd as my main cause Im gonna be using it almost 24/7 and want the fastest possible. So would the Raptor 74 gb be faster than the Caviar black 160GB? Or is the velociraptor that much faster than both.
One more thing, would 10000RPM be to much for 24/7 use? its gonna almost always be on.

nope, my 10k drives had heavy use and suffered no ill effects. Basically, buy either a Velociraptor if you can afford one, or a Caviar Black if you can't.

Ill probably Painfully buy a 150GB Velciraptor... Found one for 100$ brand new with shipping
EDIT: NVM its 20$ shipping. I still thinking of a Cav Blk
(just renamed it lol) are there any speed differences in the sizes cause Im just gonna get a 120 GB.

Oh........Oops, that caught me by suprise. I though every 150GB Raptor is a veloci, never seen any regular raptor besides the 37gb and 74gb ones.

I guess Sam has forgotten how hot the maxtors used to run.. mine was always too hot to put your hand on.. but it did a great job keeping my coffee hot all night... one day I decided to stick a fan near it.. and it failed the next day. After a year knocking about in my junk box it came back to life... some idiot has it with a load of his data backed up on it.. I bet it won't work now after a year hanging about somewhere else.
and as for how much faster.. I guess the actual answer is 2800rpm *grins*

I guess the title should be changed from 7200rpm to 5400rpm vs 10000rpm cause my Hdd is even slower than I expected. Still debating if I need a raptor though, the velocis out of my price range and Ill never even use the 500gb on the caviar black. I have a 1tb internal, a 120gb internal, 2 250gb externals and a 750gb external. 500 more is overkill (although I might actually manage to fill them all eventually lol)

Maxtors got hot, agreed. Seriously though, leave a hard disk with no fan running against it, Seagates are the only brand that will break the 60ºC mark. I actually burnt myself removing one once, I could feel that for a good couple of days.
