BD Write and ReWrite Tests - Nero CD Speed v4.7.7.16:
To test the BD writing performance of DIGISTOR's new drive I used BD-R, BD-R DL and BD-RE media from MBI, TDK and Verbatim. To get the writing times, CD Speed's "Create Data Disc" feature was used. I also ran the discs through CD Speed's transfer rate test to make sure that the DIG-79102 could read them back.

While the DIG-79102 is rated at 6x when writing to BD-R and BD-R DL media, it never reached that speed in our tests. By looking at the screenshot above, you can see that the drive started writing at 2.59x but instead of reaching its maximum speed at the end of the disc, it peaked at about 5x. I ran this test a number of times, using different media on various computers and never came close to reaching 6x.
| BD-R | BD-RE | BD-R DL | |
| DIGISTOR DIG-79102 | 22:23 | 43:19 | 47:55 |
Needless to say, the DIG-79102 did not perform as well as it should have when writing to BD-R and BD-R DL media at 6x. With its writing speed limited to 5x, it took more than 22 minutes to burn an entire 25GB disc and nearly 48 minutes to burn 50GB worth of data.
With a maximum BD-R writing speed of 6x, the DIG-79102 wasn't nearly as fast as some of the desktop Blu-ray Disc writers we've looked at recently. Nevertheless, the drive performed very well, taking a little more than 22 minutes to burn an entire 25GB disc. DIGISTOR's new drive didn't disappoint when writing to BD-R DL media either. Thanks to its 6x writing speed, the DIG-79102 took less than 45 minutes to burn 50GB worth of data.

| Verbatim 25GB 2x BD-RE | VERBATIM0 | 2x | 43:19 | Transfer Rate |
Aside from the problems writing to BD-R and BD-R DL media at 6x, the only other issue we ran into was with Verbatim's 6x BD-R LTH media. Despite giving the option to write to these discs at 6x, the DIG-79102 limited the writing speed to 4x.
Sadly, I was not able to test the DIG-79102 with any BDXL media. The discs are not available in the United States or Canada and importing them from Japan really isn't feasible as they cost anywhere from $30 to $90 each, depending on the type and capacity.
Performance Revisited:
When it comes down to it, the performance of DIGISTOR's portable Blu-ray Disc writer was hit and miss. The DIG-79102 performed as expected when reading Blu-ray Discs, but failed to write to BD-R and BD-R DL media at 6x. On the other hand, the drive did reasonably well in our CD and DVD read tests. While its seek times were a little higher than I would have liked, it read CD's at speeds as high at 24x and single layer DVD's at 8x. Writing CD's and DVD's wasn't a problem for the DIG-79102 either. For a portable drive, it turned in some respectable times and the writing quality was fairly good with most CD-R and DVD±R media. With all of these things considered, the DIGISTOR DIG-79102 gets a 7 out of 10 for its performance.
