CD Write Tests
As we stated earlier, for those who were under the impression that this drive will only write at 32x due to some
incorrect specs/feature information on the Toshiba USA Website, this is not
the case. This Toshiba SD-R5372 will write to CDR media at 48x.
Let's begin with testing...
1. CD-DVD Speed - CDR Media
The SD-R5372 uses the CAV method of writing to
CDR media. Writing is quite fast with this drive, starting at about 21x
and eventually hitting 48x. Average write speed was approximately 35x.
As with all our CDR write tests, I use the same
695MB of data and burn them to various brands of CDR media. With Ridata
branded 48x discs, it wrote 695MB in only 2:43 minutes. That's the
fastest I've have seen on a 48x drive. Below is a table of the results
with various brands.

CDR
media compatibility was excellent, writing to even a 24x Imation music CDR at
48x. The write times we see here are the lowest I've
seen with a multi-format DVD writer and a majority of the writing
was done in under 3 minutes.
If you are using one of the latest builds of
Nero 6 Ultra Edition, you now have the option to perform disc quality tests on
your burned media. With CD media, this is measure by the number of C1
and C2 errors. All discs will report a certain number of C1 errors, but
what you should be more concerned with is the number of C2 errors reported. There were
no C2 errors reported with Verbatim 48x discs and overall write quality was
good.
Checking both discs with the ScanDisc utility
also reported no file errors or damaged sectors.
2. CD-DVD Speed - CDRW Media
The Toshiba SD-R5372 supports 24x writing
to Ultra Speed CDRW media and 16x writing to High Speed CDRW media. However, it uses the slower Z-CLV method of
writing and 24x writing does not occur until it gets to the middle of the
disc. This resulted in slightly higher write times when compared to the
other drives we have looked at.

3. Over-burning and 99min CDR Media
Although I did read somewhere that this drive
does support overburning, unfortunately, I could not overburn at all with this
drive. I got the error above when attempting overburn tests with Nero
CD-DVD Speed. This included Ritek 24x 99min and Melody branded 48x 99min
discs. When attempting to perform an actual write test, Nero failed to
write to the media.
