FYI: review of the 320 GB drives.

I just got one yesterday from Best Buy. The one thing I do notice is that the Buffer size is 2MB. I wonder if this makes a huge difference as the Scorpio had a Buffer size of 8 MB. That is the only difference I can see between the Scorpio and the Passport.
How did you determine this?
I just installed mine, and I can find no mention of the buffer size at all on the drive itself --- just a bog-standard Scorpio part number: WDC WD3200BEVT-00ZCT0.
Is there a way to determine this via software? System Profiler and Disk Utility don't report it.
For what it's worth, my boot time seems much faster now, versus my previous 160GB HDD. (And no, this isn't a new OS installation --- I Carbon Copy Cloned)
It said that when I went to purchase the Passport at Best Buy last night. It said on the yellow card "2Mb Buffer". It could be wrong. I won't really know until I open up the passport and see the drive information physically ( at least to get the model #). If the drive in the enclousure says "WDC WD3200BEVT-00ZCT0" then its just the Scorpio place into an enclosure. If it says something different, I need to see how a 2MB buffer is going to affect performance.
Ok, at this point I'll just trust that I have a full Scorpio, as my label looks nearly identical to the one in the Tom's Hardware review, model number and all:

WD3200BEVT-227CT0
Very interesting. So there definitely are slightly different models in use here.
There are also 2 different models of WD Passports. One is WDXMS3200TN and the other is WDME3200TN.
I wonder if each has a different version of the Scorpio in it. I know the XMS one is newer, so maybe it is the one that has a newer drive with 8MB cache and the ME has a 2MB cache?
Major bummer, here.
After using Carbon Copy Cloner to put my former drive contents onto the Scorpio, Time Machine now wants to back everything up again. ...there goes 100GB of my Time Machine drive for no reason.
A note to others who may encounter this issue:
Don't use Carbon Copy Cloner in the first place! Just install the blank drive, boot off your Leopard DVD, and choose Restore from Time Machine. Then, you'll just keep on trucking from that restore point.
So simple, I can't believe I overlooked it.
I just popped the WD Passort open....the hardware number is:
WD3200BEVT-227CT0
Now if I do a search on WD3200BEVT I can see its a scorpio. Not sure what the other numbers are "227CT0"
Man popping that open was a bitch. My fingers are raw!
What if someone isnt using Time machine? Is carbon copy still a viable option?
Yes, but in all honesty, I don't bother with it. I just pop the old drive in the enclosure, install Tiger/Leopard on the new one, and use the Migration Assistant to pull everything off the old drive (now in the enclosure and connected via USB) and I'm off!
