Why remove old hdd when installing a ssd?

[jonneymendoza]

As title says, why? whats the major benifit? i just got my first ever ssd, a ocz ventex 2e 120gb and did not disconnect any of my 5 mechanical hdd's and windows installed well.

i also installed most of my other apps fine as well and so far so good. AHCI was enabled before i installed though so why do i keep hearing people suggest that you disconnect all other hdd's before installing the OS on a ssd?

ahh ok so nothing about reducing performance of a ssd or anything like that?

teh boot files are the ones that take up only liek 100mb? i notice how everytime i use to install an os on my mechanical drive it says how it needs to reserve space for addtional OS files?
