I can tell from
the email I'm getting that there's a lot of
interest in the Toshiba 60GB 5400rpm "GAX" 2.5 inch
9.5 mm drive with 16MB cache and the Hitachi* 80GB
4200rpm Travelstar 80GN 2.5 inch 9.5 mm drive with
8MB cache.
Which is the
fastest? Which is quietest? Which makes the best
replacement drive for a PowerBook G4? Which
performs best in a FireWire case kit? And which
FireWire bridge chip works best with these drives,
the Initio 1430 or Oxford 911? And is USB 2.0 still
slower than FireWire?
I tested the two
newest drives, two fastest "2002" drives (40G GNX
and GAX), and the original drive that came with the
PowerBook (40G GAS).
ANALYSIS
Although the
Toshiba 60GB "GAX" was fastest 4 out of 6 tests, I
think the Hitachi* 80GB "GN" is the best overall
choice to upgrade your PowerBook. For one thing,
even with the slower spindle speed and smaller
cache it was first or second fastest in 5 out of 6
tests.
Furthermore, I
was struck by how quiet the Hitachi* 80GN drive
was. While the Toshiba was whining and clicking,
you could barely hear the Hitachi* purr. Both
drives have fluid dynamic bearings in their spindle
motors but Hitachi* has added further dampening to
their voice coil motors and actuator.
Finally, the
Hitachi* 80G drive holds more than the
Toshiba.
FIREWIRE
versus IDE (ATA)
Do the drives run
faster or slower if put in a FireWire case kit?
Overall, the drives ran 2% faster when testing in
FireWire case kits. The Hitachi 80G GN gained the
most from being in a FireWire case with its 6%
increase, pushing it past the Toshiba 60G GAX as
the fastest FireWire notebook drive.
In other words,
if you add storage to your PowerBook using an
external FireWire drive, you aren't giving up any
speed.
I tested the two
newest drives with both Oxford 911 and Initio 1430
bridge chips. The speed difference was
insignificant with the exception of the Toshiba 40G
GAX which was "happier" in the Initio
case.
FireWire 400
versus USB 2.0
I didn't have a
USB CardBus card for the PowerBook but I did test
the Toshiba 60G GAX in a Wiebetech
MicroGB+ Combo kit connected to an Orange Micro USB
2.0 PCI card which was installed in a PowerMac
G4/1.42 MP. The drive ran 44% faster using the
FireWire port.
USB 2.0 remains
slower than FireWire or IDE/ATA in the real world,
no matter what they say about theoretical speed.
And FireWire 800 is only going to widen the
gap.
WHERE TO
BUY
TransIntl.com
has the lowest price on the Hitachi* 80G Travelstar
80GN drive.
GoogleGear.com
has the lowest price on the Toshiba 60GB "GAX"
drive .
Wiebetech
will sell you a dual port FireWire or FireWire/USB2
Comob case kit with or without the drives mentioned
above.
TEST
NOTES
The internal ATA
and FireWire testing was done using an
Apple
Titanitum G4/800 PowerBook with 1MB of
SDRAM.
USB 2.0 vs
FireWire 400 testing was done using an
Orange
Micro USB
2.0 PCI card in an Apple
1.42GHz MP Power Mac.
FireWire and USB
2.0 case kits were the MicroGB+ from
Wiebetech.
