SCSI - RELAX vs others

[cara@dorsai.dorsai.org (Cara A. Bissell)]

Summary:  My Relax 20 megabyte hard drive recently went on my //GS.  I've put
in a request for a MSDOS 200 megabyte hard drive which will be utilizing the
unix system.  A guru friend of mine will be setting it up for me.  I was
wondereing, just to help me be more knowledgeable when he does it, 

will the exisiting scsi card in the GS be the one to control the new 200 meg
hard drive?  Will using the low level Apple software ( that I used with the
RELAX hard drive and did not come with the relax hard drive ) be what I can
use with this new hard drive??

Thanks for your response ahead of time whoever, whereever you are!
