These new SATA II/perpendicular disks rock on reads... test was done here:
See subject-line/title first...
(& then, this comparison in the URL below that I did here vs. one of these types of disks)

I.E.->
A.) Dual WD "Raptor X's" in RAID 0 driven via a Promise SuperTrak EX8350 128mb Caching Controller w/ Intel I/O CPU onboard (this one "surprised me" a bit, it beat its 150gb/sec SATA I transferral bus ceiling, but it's probably bursting out of its cache & Hdd 16mbx2 buffers in RAID 0)
&
B.) Also vs. a CENATEK Solid-State Ramdisk drive (PCI 2.2/PC-133 SDRAM constrained though, vs. the newer bus-types used in SATA I (in the Raptors) & SATA II (this perpendicular technology disk))!
(Results on a disk using this technology were ASTOUNDING in read-speed... especially what I put them up against, very different "high-end" technologies vs. it)
APK
P.S.=> In "burst-read" scenarios, imo @ least, these new SATA II/perpendicular technology disks are incredible...
However, vs. the competition I put them up against, this new perpendicular recording disk used more CPU (understandable, the disks I used have onboard io-controllers to lessen this) & in access/seek time, they were slower than both of what I put up against them... apk
