I have had CD-RW media which were labelled 4x, but I could write
them at 10x. They read out as:

ATIP info from disk:
  Indicated writing power: 3
  Reference speed: 6
  Is not unrestricted
  Is erasable
  Disk sub type: High speed Rewritable (CAV) media (1)
  ATIP start of lead in:  -11940 (97:22/60)
  ATIP start of lead out: 335975 (74:41/50)
  speed low: 4 speed high: 8
  power mult factor: 1 5
  recommended erase/write power: 5
  A2 values: 00 00 00
  Disk type:    Phase change
  Manuf. index: 43
  Manufacturer: Acer Media Technology, Inc.
  Blocks total: 335975 Blocks current: 335975
Blocks remaining: 22593
Starting to write CD/DVD at speed 10 in write mode for single session.

Further, I have had other CD-RW media which I could burn at 8x and 4x,
but not 6x.
