HD parameters explanation need.

Hi everyone!

Just wanted to ask some little question that's bothering me a lot.
Recently I took a look at WD hard drives.
Generally my question is:

If I would take two HDs with these parameters:

1. X(GB) 16MB of buffer and 10kRPM
2. X(GB) 32MB of buffer and 7.2kRPM

X(GB) - actually doesn't matter.

Which one is better, the higher buffer size or RPM speed?
And which one of those two parameters more affects the HD's
performance and why?

Sincerely.

Tnx in advance for help.

Is life an issue?

As to buffer or RPM the problem while deeply discussed can by answered by "benchmarking with your application." Let's be clear that some SQL database may work better on one drive and a home user would get better results from the other drive as their benchmark was "time to load my game."

So far given the limited factors you supplied, the winner could lose as we change our benchmark.

ok, so lets take two specific HD:

1. WD CAVIAR BLACK 1TB SATA2 7200RPM 32MB BUFFER
2. WD 300GB VELOCIRAPTOR SATA2 10000RPM 16MB BUFFER

Lets assume that their main usage will be for home PC with WINXP PRO.
How do I need to compare these drives?
And what about SQL database you mentioned above, can you give some more explanation please.

Thanks for help.

About SQL.

Please use google as my explanation would just duplicate web content.

While you narrowed it down that you are not using SQL but home, what sort of home user?

Gamer? Might want the 10K drive.
Home user? Needs space for video files, etc.
