Are 10,000 rpm disk worth the money?

When I bought my computer 3-4 years ago I got SATA and 10,000 rpm disk
drive.

I want to add a bigger disk now and wonder what the current evaluation of
10,000 rpm disk is.

Are they worth the extra money?

Are they popular now?



Thanks

Speed costs money. How fast do you want to go?

They never were popular with makers of garden-variety PCs, since those
folks prioritize low cost over high performance.

If you want really fast, try a RAID0 set of 15K RPM SCSI HDs on a
hardware RAID controller; anything less is just a compromise.

Actually, some of the new SSDs look like fun. The MTRON here, is
something like $1200 each, and you can RAID them :-) One limiting
factor, is in the comment section of the second article, the
device is limited to about 125 writes/sec. For writing small
random files, that can be quite a restriction. But for large
linear writes, these are quiet and fast.

Have a good look at the specs...especially data transfer rates...
the few 10,000 rpm drives I've spec'ed out did not seem to be any better
thab 7200 rpm drives...
though they were a lot more expensive!

Lower seek time is an advantage of higher RPM disks. Max transfer
rate varies, especially when comparing different generations of head
technology.

And for some numbers, this site has a few. It is interesting, that a
WD Caviar 750GB, actually has a faster sustained transfer rate (97MB/sec),
than the Raptors.
