It's kind of like somebody telling you the exact date of your death and how it will happen.

The only consumer 10K RPM HD are the Raptors. Those are basically 5 year old technology (even the newer 150GB models). Now that the VelicoRaptor arrived with improve technology... go compare them to ANY 7200RPM hard drive. VelicoRaptor beats them by 30% or more.

The 5yr old Raptors still hold out against brand new Samsung Spinpoint F1 (which is a top performer). Think about that..... 5yrs in the PC world. That's 4 video card generations or 2-3 CPU generations.... and only recently Raptors are getting beat.

The article does not state that these drives do not outperform others, it's obvious that they can.

However, even the velociraptor has very poor performance per dollar. It costs at least three times as much as a good ~300GB 7200rpm drive, but does not come any where near having 300% of the performance.

So, while some people are willing to pay more for this performance, it's not for bang for the buck reasons.

Anyone who cannot partition a drive, or use the manufactures software to set a different capacity in the firmware, probably does not have the know how to to select the best drive for their needs anyway.

waste of $$$.. those 10k+ rpm drives never caught my attention... sure 1.5 sec in loading time is so not worth the money...

It's kind of like somebody telling you the exact date of your death and how it will happen.
But that's not necessarily a bad thing, particularly in the critical business functions at which these drives are currently being marketed. Makes it easier to plan and budget ahead of time.

As is true in all things technological, price does not increase linearly with performance. You see it with CPUs, memory, networking gear, etc. So while what you're saying is true, it's not really an important argument...it's simply the status quo.

Well, what I really meant by that is that no one (or very few relatively speaking, to be more accurate) is going to buy a 500GB drive and only use 200GB of it (or whatever number makes sense). It's just not human nature. If we have 500GB available, we're going to use 500GB.

And in the data center I run, I can tell you that the demand for ever increasing storage capacity far exceeds the demands for faster storage. Granted that my apps aren't at the same speed requirements of, say, banking or telecom apps; but still, I think this is probably the case in a very large number of data centers.
