I was wondering what the cache size was on the upgrade 500GB Serial ATA Drive @ 7200 rpm that Apple is offering? Does anyone know what drive they are using for this?
Thanks.

500GB HD @ 7200 rpm ?

At the Apple store the 17" MBP had a 5400RPM Hitachi HD. Don't know about the 7200RPM version. I should know no later than May 4. 
Well, I believe the two laptop drives of that size and speed available right now (Seagate momentus 7200.4 and Hitachi 7K500) both use 16 MB caches.
idk, I'm looking at the 15" 2.4 i5.. the 500gb 7200rpm hd is + $135... you can buy the same/better hard drive for $80-90. And you can throw the 320 that it comes with in an external enclosure. I don't see why anyone (who's buying the 2.4) wouldn't do this.. I looked it up and swapping the drives doesn't seem hard.
I think a lot of people simply don't want to take the time to buy the 7200rpm drive and install it themselves. I bought a Hitachi 320gb @ 7200rpm drive and replaced the stock 500gb @ 5400rpm drive in my 17" i7. I then took that 500gb drive and put it in an external enclosure to use as my Time Machine backup drive. Works perfect!
This is why I'm asking... The upgrade is only $50 on the 2.66. So, I'm wondering why it's so cheap (other than a bulk discount for Apple).
I should know no later than May 4.
Thanks, I'm still saving, on a student budget, and can't purchase until mid-May.
Breathesrain: That's what I see as I research, as well.
