Hello guys , im planning to buy an ssd and install OS now my question is what should i get the oem or the retail?  if i install the oem version ,  can i put my ssd on the different comp

i hope u understand what i mean 

Sorry for bad english and thank you

"comp" you mean computer? If so, you can't transfer a hdd of any kind to a new machine without re-installing Windows.

Please post in the right subforum next time.

Take OEM. The same thing, just cheaper.
