drives we converted to "SATA" with the
adapter did very well. The converted Hitachi 180gxp
RAID 0 pair beat or tied the fastest "native" SATA
drives in 2 out of 3 Real World tests. The
converted Maxtor drive beat the "native" Maxtor
SATA drive in two tests.
only downside with using the
adapter is that you can't close the door
on the G4 tower. I've suggested a simple design
change to the company that would make the
adapter more viable as a way to convert existing
internal drives to SATA. Until then, they will
need to remain as PATA drives or be put outside
the box in a FireWire 800 enclosure.
If you are
buying a G5 and need more than two drives or
are wanting to keep the drives you have, the
best short term option is putting them in a
FireWire 800 enclosure. However, expect some
SATA products to appear that enable you to put
extra SATA drives (or converted PATA-to-SATA
drives) outside the G5 tower.
