I have many NTFS drives, and will be sharing them between a PC (XP SP2) and OSX via external USB2 enclosures. I don't want to change my drives formats to HFS+ because I have alot of data on them...also I have to buy MacDrive for that and is that really that stable for work? IE format all drives to HFS, and use MacDrive 7 to have XP read these discs...will I get maximum data rates that I used to get with the NTFS format? Which one is a better solution? Thanks folks.
