Ok, for those who have been following my VelociRaptor HD
Mac mini Hack I've done something you might find interesting
and possibly useful.

If you remember, I attached a 300GB VelociRaptor with a
cloned OS via Firewire 400 to the mini. The performance
increase was unbelievable. Then I attached the VelociRaptor
to the mini via its internal SATA port. Yes the performance
was better, but you could figure out it would be.

Well, Philip Arcario sold me one of his cooling fan modified
SansDigital HD enclosures. Its the TowerStore TS2CT.
It holds two 3.5" Hard Drive in RAID-1 or RAID-0 and
is bootable via eSATA, Firewire 400 & 800, as well as
USB.

I have two 600GB 10K VelociRaptors sitting here collecting
dust. Yes your right, I dropped those two bad boys into the
SansDigital, set it to RAID-0 for speed, cloned my iMac PPC
G4 too the RAID-0 VelociRaptors and then rebooted the iMac
using the SansDigital RAID-0 Velociraptors via Firewire 400.
(Can you say that fast three times?)

Some things were a little faster and some things were a
little slower. I guess you could say it was a wash. The
reason I did this little experiment was because of the
amazing success with the Mac mini/Velociraptor/SATA
hack. My intention was to clone my Imac G4 PPC's Hard
Drive to a Velociraptor and install it in the iMac's stock
Hard Drive location. Using an IDE-SATA adapter.

I now know not to bother. What was a fabulous success
with the Mac mini was pretty much a failure with the PPC
iMac. The processor was the weak link. If you were
doing something that taxed the processor, faster HD's
didn't help much. And don't forget a Velociraptor runs
a lot hotter. I don't know if it would slowly cook the
iMac's insides. It probably would.

Sooner or later I'll get a 2011 Mac mini and use the RAID-0
VelociRaptor SansDigital attached via their SATA ports.
I wonder if I'll like it.

A lot of waisted performance on the iMac
PPC but killer performance on an Intel mini.
