With BD-RE there are three format types : 00h, 30h and 31h.
00h offers the default size format.
30h offers several sizes with defect management. Usually there are three
size th choose: #1: default size, #2: maximum spare area, #3: minimal spare.
size to choose: #1: default size, #2: maximum spare area, #3: minimal spare.
31h offers a single size and disables defect management. This has the side
effect to speed up writing to nominal speed.

Usable with 31h seem also 00b Quick Reformat and 01b No Certification.
(mmc5r03c.pdf 6.5.4.2.15.1)
Other format types have their certification intensity controlled by
a pair of bits: CmpList and DCRT.
CmpList resides in CDB byte 1 as bit 3. DCRT resides in the payload byte 1
as bit 5. Both together should request a quick size change without lengthy
certification but maintaining the list of known defects.
(mmc5r03c.pdf 6.5, table 249, 6.5.3.2)
With DVD-RAM on my PHILIPS SPD3300L drive they prevent any format size
change though. The TSSTcorp SH-S203B works properly.
With BD-RE format 00h, the default is specified to be Quick Reformat,
and with 00h in general certification can only be disabled not enabled.
