Yes, dump the ATA drives.  Most have no check-sum or error correction
anyway,  so "new" is a very false sense of security.

I have a performance tuning section in my LDAP presentation -
ftp://kalamazoolinux.org/pub/pdf/ldapv3.pdf

As well as a general performance tuning presentation (for LINUX) at -
ftp://kalamazoolinux.org/pub/pdf/PerfTune2001.pdf

And a presentation on Disk Management which explains why you should
ditch ATA and has some performance related info-
