Doesn't sound like me, 'think there's some quoting mis-attribution

Well, this _does_ sort'a sound like me ;) Sort'a dated tho. IIRC,
before some of the Mandrake 2.4.18-6 kernels, there was some
consternation about VIA chipset bugs and some hestitation from the Mdk
and other developers. Turns out that the VIA chipsets are no more
flawed, probly less so (ie, erratta), than any that are currently even
worse (eg, Intel-i8xx, SiS, Nforce, etc.). Actually the truth is that
any chip ever released has an errata list 'bout 80+ items long. Some
twice that much.
'Anyhow, whatever' �, currently with 2.4.19 kernels (mdk kernels are
already including some 2.4.6 tech), the chipsets showin the most
problems aren't VIA. Intel, SiS, Nforce et al, still lead the pack in
that regard. Gettin back to hdparm, it hasn't been neccesary for some
time now, 'cept on some buggy hardware, to get max performance. ata/33
drives should yield 11 mb/s, /66 drives 22.5, /100 drives 40 burst.
Past ata/100, includin serial/ata, it's currently just sales talk. They
all still run on the PCI-idebus bus at 33 mhz.
That 80g in the subject should be doin 40mb/s (hdparm -t /dev?) at
udma5, unless there's a mobo or other hardware problem. Winder$ B$
(eg, HdTach) might even report higher burst speeds, since M$ likes to
say stuff in 1000x1000 terms, 'stead of base16, 2's complement computer
reality like 1024x1024 (~95% less).
