I ran analysis software of my drives (all SATA) and here's the numbers I
got:

Seq. write: 50.92MB/s
Seq. read: 54.68MB/s
Buf. write: 55.96MB/s
Buf read: 99.62MB/s
Random read: 25MB/s

Do these numbers sound off? I'm pretty sure they're at least comparable to
the IDE's that I replaced. I sure don't want to go to the trouble of
starting from scratch since it's taken me almost two months to get my system
back where it was. I'm going to run HD Tach and Leoni's app and see what I
get.

HD Tach numbers would be more useful in comparing the drive. My Seagate
320 GB SATA II drive: sequential read is 64.4 MB/s average, with about
73 MB/s at the beginning and about 45 MB/s at the end.

Burst speed is 215.4 MB/s

The newest version of HD Tach is 3.0.4.0

Those are smokin' compared to what I used to get on my drives the last
time I checked a few years ago.

My advice now is the same as my advice then: Looks good enough. The
hard disk isn't a bottle neck. Move on.

I don't think the fact that the CPU is the bottleneck has changed over
the last couple of years. If anything the plug-ins will have gotten
more CPU hungry.

I see HD Tach is $45 so I won't be running that. Mine are 500GB Sata's so I
guess mine are running about as good as can be expected (and apparentely in
SATA mode)?

They're UDMA.
