Fastest SATA 3.0 drive?

[ExcaliburMM]

When speaking of non-SSDs, what is the fastest type of HDD? I figured either a raptor or one of the single platters with 32mb but I'm not sure.

Are the platters larger in diameter on the non-Raptor drives?

Looking at these pictures I might be inclined to say YES.

Now if platters are larger diameter on non-Raptor drives wouldn't that negate any disadvantage due to lower RPMs? (re: surface area scanned by drive arm is related to both diameter of platter being read and drive speed)

non ssd, then the raptor has the fastest seek times, for sequential read writes then probably one of the new drives with the 500gig platters (though the raptor is close).

According to the 4th post in this thread Raptors have 2.5" platters while larger drives have 3.5" platters.

So what is the big deal about 10,000 rpm vs 7200 rpm if this is true? (Wouldn't larger diameter platter somewhat offset the decreased RPMS in terms of surface area read per unit time)

Now if we were talking 3.5" Platters spinning 10,000 rpms vs 3.5" Platters spinning 7200 rpms then maybe the differences would be greater.

Heres my picks for large Sata 3 drives

1. WD black caviar 1 TB (Overall winner despite being expensive)
2. Samsung Spinpoint 1 TB
3. Hitachi 7k1000 1 TB (Overall bang for buck winner)
4. Seagate 7200.12 T TB

Caviar is the best overall , Hitachi is the overall winner in price / performance ratio (as of today when i wrote this, i scored a hitachi drive for 78ish with the 10% 1 day newegg coupon)

I was under the impression that the new Seagate 500 GB 7200.12 smoked the 1TB drives in every aspect. No?
Here's a pair in RAID0 short stroked

The fastest nonSSD HD would be a 15k SAS drive.

it would. at the cost of random writes / seek time because it takes longer for the heads to move from the center to the outside. the raptor being 2.5 inch sacrifices some sequential for random performance and seek times

Depends if you want access time (2.5" 15k drives) or sequential read performance (3.5" 15k drives).

Then again, the title says "Fastest SATA 3.0 drive?" so SAS is excluded.

The question is whether this is a OS or storage drive. Most home users that need storage have relatively large files compared to an OS access pattern.

Velociraptor is going to smoke any non-SSD SATA drive out there. They are faster in access times and seq. transfers than 10k rpm SAS drives in desktop usage.
