for anyone wondering what's inside the techPulse120 external slim Blu-ray drive (sold on Amazon.de and techpulse120.com):
Manufacturer: MATSHITA
Product: BD-MLT UJ272
Revision: 1.01
Bus encryption flags: 1B
LibreDrive: not supported
Results with MakeMKV 2.0.0 on Windows:
DVD: works fine, approx. 3.5x (4.7 MB/s)
Blu-ray: works, approx. 2.1x (9 MB/s)
UHD: not tested (not a UHD drive)
Update after about 35 discs:
I have now ripped around 35 DVDs and Blu-rays of all kinds – older titles as well as very recent releases. Every single disc was read and processed without any problems: no read errors, no failed titles, no retries needed. The drive runs quiet, stays cool and has been completely reliable.
Conclusion: If you only need DVD and regular Blu-ray (no UHD), this is an inexpensive and trouble-free choice for MakeMKV. Recommended.
