i.e.. 1x. In other words, if you need some 70 minutes to burn the whole CD
(650 MB) at 1x, it takes 35 minutes at 2x, 17,5 at 4x and so on.
Speed of reading and writing are definitely two different things. Reading is
always much faster and does not depend on the speed with which given CD was
written. All speeds are always indicated next to the drive name as three
numbers. The first means the speed of writing the CD-Rs, the second - speed
of writing the CD-RWs (usually the lowest), and the third - speed of reading
(the highest). For example, my CD-RW has the following characteristics:
4/4/6. It means that I can record CD-R and the CD-RW at the 4x, and read
them at 6x.
But there is also another parameter included, namely the speed of transfer
of data between your computer and an external CD-RW drive. This exactly what
depends on the type of connection. Briefly: the parallel port is the
slowest, the USB is better, the Firewire is the best. As I mentioned, I have
USB version 1, and this probably why I can use only 2x and not 4x speed for
But as long as one do not copy the whole CD but operates on archive or
backup files of around 200-300 MB each, the 2x is OK, meaning that you need
some 10-15 minutes for one file.

I just wanted to add to the conversation that not ALL Packet
Writers support writing to CD-R media (versus CD-RW media). In
fact, this appears to be the NORM, not the exception.
Also, I have used a 1999 edition of Veritas Backup Exec and it
would NOT recognize my IDE CD-RW nor my USB ZIP drive. That was
the last Veritas I intend to purchase; I absolutely could not
determine from their retail box nor their web site what EXACTLY
was supported as back up devices before purchase. It looked good
to me. I was disappointed.

supports your drive. I had an "old" version of CDRWin from April 2001,
but it could not know my new drive because it wasn't in production back
