I am assuming that the SDD is quicker, given the Apple website description,
"...solid-state drive (SSD), which has no moving parts and delivers increased drive performance for many operations".
however would one really notice the difference in loading applications / documents etc..i thought it is was the memory and speed of the processor that did the 'speed' thing
if this is true, what is the benefit of the SDD?
Thanks in advance
The capacity is limited because SSDs are still relatively new and expensive.
The speed advantage is due to the fundamental design differences. In any process (and data storage and transfer is a process) the slowest step is the bottle-neck. In this case for ATA and SATA drives it is the electro-mechanical interface between the spinning disk platters and the heads.
In an SSD (solid state drive) this interface is missing and data transfer speeds are limited only by the electronic interface.
All of the above is a simplification, but I hope it helps.
I've always wanted to be smart, handsome and modest. But, I guess I'll have to be satisfied with two out of three . . .
