3.5" 7,200RPM vs 2.5" 7,200RPM


C

I'm considering using a 2.5" 7,200RPM as a primary C: drive for the OS
+ applications, would it run as fast as a 3.5" 7,2000RPM? i.e. latency
and throughput. I'm aware it's more expensive per GB but that doesn't
affect since it's only for the OS installation and not for massive
storage space. Would I be correct it that it would use less power and
generate less heat also?

Seagate Momentus gen 3 notebook HD draws 5 Watts max and 2.1 Watts avg, while
the 3.5" Barracuda gen 11 HDs draw 38 Watts max and 8.5 Watts avg.
HOWEVER, notebook HDs are designed for 5V power, and desktop HDs are designed
for 12V power. Make sure your MoBo has the proper interface for a 2.5" HD...

For SATA hard disks, both 2.5" and 3.5" are the same. So...?

So a 2.5" SATA drive will use the same power connector from my PSU as
my current 3.5"?

Yes, and that's why we have this:
