Format speed?

[dbminter]

Is the format speed of rewritable media the same as the maximum write rate for that media?  For instance, if you had a 4x DVD-RW, formatting it would format at 4x speed.  And a 6x DVD-RW would format at a 6x format speed?  Thus, the 6x DVD-RW would finish formatting sooner than the 4x DVD-RW?

 

 

I'm guessing this is the case because isn't a format just writing out zeroes to all sectors?  This implies a write operation and the maximum format speed would be the maximum write rate. 

 

 

Is that so?

Yes, the format rate would match the write speed rate.
