Blu-ray Writers: Internal SATA and USB Burners

Write speed, disc types and what 16X means

A 1X Blu-ray speed is 4.5 MB/s, so a 16X writer peaks around 72 MB/s, and the listed BD-R speeds run from 4X to 16X. The disc's own rating caps the speed; slower discs burn slower however fast the drive is. Single-layer BD-R holds 25 GB and dual-layer 50 GB, BD-RE can be erased and rewritten, and 100 GB BDXL discs need a drive that lists BDXL. Writers also record DVDs and CDs, so check the DVD+R and CD-R speeds as well.

Internal, slim or external: connection and 4K support

Desktops take an internal 5.25-inch SATA writer; laptops and small cases take a slim writer on the compact slim-SATA connector; external USB models suit anything with a port, and USB 3.0 matters because 16X Blu-ray writing outruns USB 2.0. Playing 4K Ultra HD discs is a separate requirement: it needs a drive described as UHD friendly, compatible player software, and a display path that supports the discs' copy protection. Ordinary movie playback on a PC also needs licensed player software.

Questions about Blu-ray Writers: Internal SATA and USB Burners

Can a Blu-ray writer burn DVDs and CDs?

Yes. A Blu-ray writer records Blu-ray, DVD and CD discs, and the listing gives a separate speed for each format. Check the DVD+R and CD-R figures if you burn those discs often.

Will a Blu-ray writer play 4K Ultra HD discs?

Only drives described as UHD friendly are suited to them, and playback also needs compatible software and a supported display connection. For plain data burning, UHD support is irrelevant.

What is the difference between BD-R and BD-RE?

BD-R records once and suits archives. BD-RE can be erased and rewritten, which suits temporary copies. Both come in single-layer 25 GB and dual-layer 50 GB; make sure the drive supports the layer count and speed of your discs.
