I dd from CD-ROM and DVD quite often to make iso images for mounting under VMWare ESX server. I always use a bs=512 in the dd command when creating the ISOs. I've never timed it, but also never been disappointed with performance - most data I've ever dd'd from optical media is around 1.4Gb.
Cheers

patchmedia
patchmedia(1M) System Administration Commands patchmedia(1M)
NAME
patchmedia - modify Solaris media with patches and packages
SYNOPSIS
/usr/bin/patchmedia -d media-root [-v] [-o iso] [-l label]
pkg_or_patch [pkg_or_patch ...]
DESCRIPTION
The patchmedia utility takes a list of patches and packages as input and updates the install miniroot in media-root (the root directory of
an on-disk image of a Solaris installation media) to include the specified patches and packages. These patches and packages are also placed
in a subdirectory called DU under the Solaris install image. For example:
media-root/Solaris_10/DU
When booting a system from the updated media, the patches and packages will be part of the booted Solaris image. They will also be applied
to the target system being installed at the end of the installation process.
If -o is specified, a bootable ISO image is created in the file media.iso that contains the Solaris install media. The ISO image can then
be burned onto a CD/DVD with utilities such as cdrw(1) or cdrecord(1). (The latter is not a SunOS man page.)
OPTIONS
The following options are supported:
-d media-root
Top-level directory of on-disk image of Solaris installation media. This is option must be specified.
-o iso
Create a Solaris ISO image of media-root.
-l label
Label/volume name of the ISO image (if -o option is specified). If -o is not specified, the name of Solaris directory under media-root,
for example, Solaris_10, will be used.
-v
Verbose. Multiple -v options increase verbosity.
OPERANDS
The following operands are supported:
pkg_or_patch [pkg_or_patch ...]
One or more patches or packages (you can have both patches and packages in a single command) with which the Solaris installation media
media-root will be updated.
EXAMPLES
Example 1 Updating a Solaris Install Image with Patch and Package
The following command updates the Solaris install image in s10u1 by adding patch 123456-07 and package SUNWfoo.
# /usr/bin/patchmedia -d s10u1 SUNWfoo 123456-07
