This is the best explanation I can give you:

It shows you how it writes in a diagram below.

I believe it is the 7200.9 and 7200.10 models that have this.
So what I am getting is that perpendicular storage increases hard drive capacity, not speed?

It does increase speed but it also increases storage more than it increases speed.

It allows for more space in a smaller / same sized enclosure.

From what I understand from those two links, yes, it increases capacity.

Haven't seen any info about why it is faster. (From claims of people who have used them).

Since there's more data per square cm, it can read and write faster.

Sorry Raptor owners but I see no point in shelling out so much money for a drive that spins at 10k-rpm and and have only 75GB of space, so don't get offensive.

IMO, performance wise it wouldn't be noticeable between a Raptor and Seagate Perp's, so I'll always recommend the Perp's over Raptor because of price and 3x the size amount of extra space the perp's drive would give you and of course being somewhat less expensive.

ok well I just moved over from a RAID0 setup with 2xWD 3Gbs SATA to a 74GB Raptor and I can't notice any difference. I mean apart from synthethic tests the perform and feel the same for me, programs load at around the same speed, and windows boots in around the same time. So my advice would be to get the larger storage drives and raid0 them, as long as you have another drive equal to the size of the raid0 to backup.

Personally i'm going to go for a RAID0 of 2x36GB raptors and store my OS on that then have some sata drives as storage and my program files, its the best of both worlds, a raid 0, redundancy and 10k rpm
