New Hard Drive installation/Dynamic instead of Simple/Question

I just bought a new 250Gb Enhanced IDE HD and installed it in my system To this effect I unplugged the CDROM drive and replaced it with the new HD (I know ATAPI is slower, but I only did this temporarily just to transfer my main 2nd HD files). Then I went to Control Panel/Administrative Tools/Computer Management/Disk Management and followed the wizard to give it an NTFS format. After transferring all files from my main 2nd HD I replaced it with this new 250Gb drive. After also reinstalling the CDROM drive and rebooting everything is fine (it shows in MY SYSTEM with all transferred files in it). I have one concern though I went back to Disk Management Console and the drive is listed with a different satus as follows:

The main OS primary drive has a "Partition" Layout whereas the new 250Gb drive has a "Simple" Layout. Also, the Type shows as "Basic" for the primary drive whereas the Type for the 250Gb drive shows as "Dynamic". Are these settings fine? Or should I reformat the 250Gb drive so that it shows a Partition Layout and a Basic Type like the primary drive? Will leaving everything as is now cause any kind of performance/reliability problems?

Thanks for your help.
