Raptors or Perpendicular??

post #1 of 29
Thread Starter 
I have two WD 74GB Raptors (8MB Cache version) right now that I am planning to run in RAID 0. I was wondering if two Raptors would run faster in RAID 0 then two Seagate 320GB Perpendicular drives in RAID 0 or visa versa.

If anyone has any good places to buy these, I am open to any suggestions.

I can also buy any other HDD's, I just want the fastest with SATA.

The 750GB Perps are as fast as 150GB Raptors, otherwise, the raptor is faster. Just for reference.

Raptors 8MB is comparable to Perpendicular drive 16MB. I'd get the Perp drive if i were u.

So would a 36.7 GB Raptor be faster than a 74 GB Raptor?

No, the data density is less, so less MB per turn.

The density on the 750GB Seagate is so high, that it meets or exceeds the Raptor X even though it's at a 2800RPM disadvantage.

Well would two 320GB or 250GB Perps in RAID 0 do better then the one 720GB Perp??? I think I will make the change to Perps soon, I just needed to know so I can order them.
