[Ti] new drive for macbook

[David Delmonte]

I have swapped plenty of drives in my powerbooks, ibooks and macbooks.  
The thing is, what computer do you have. I do not think you can put a  
SATA drive in a Ti Powerbook. I'll do some more digging in the morning.

Hi Alexandre,

In November bought a WDC Passport 250GB USB external HD for $150  
including tax at Best Buy.  It had a SATA drive in it so I just cloned  
my Mac to it then swapped the drives.  I now have the 250GB internal  
and put the original 120GB into the enclosure.  The whole process,  
including copying, took maybe an hour.  I don't think it took more  
than ten minutes to actually do the physical swap.  It took a bit of  
fiddling to figure out that the external enclosure just snaps  
together.  I was a bit timid about prying on it until I got a corner  
started and saw how it went together.

It is a 5400 RPM drive and is plenty quick.  The actual spindle speed  
is not super critical to the speed of the drive.  What matters is how  
fast the bits pass by the read head.  All other things equal, a 4200  
RPM 128GB disk will have about the same read/write speed as a 5400 RPM  
100GB as the bits are packed closer together on the track.  The seek  
time is directly related to the rotational speed.  On average, the  
platter has to make a half-turn to get to the requested sector.  The  
4200 takes about 14ms per turn and the 5400 about 11ms.  These are not  
huge differences.  I do notice a performance difference but I can deal  
with either.  The slower drives do use less power and put out less  
heat.  If you are running on batteries most of the time, it might be  
worth going for the slower unit.  They are cheaper too.

Of course it depends on what you are running.  Editing video demands a  
faster drive.  Checking email doesn't care.

Cheers,

Scott
