Plextor PX-B310U External PX-B310U Blu-Ray USB DVD Writer Review
Plextor PX-B310U External PX-B310U Blu-Ray USB DVD Writer Review - PCSTATS
Abstract: On the test bench today is Plextor's PX-B310U external Blu-ray drive. In addition to Blu-ray playback (but not burning), this full sized external ODD, which connects to the PC over USB2.0 cable, doubles up as a DVD and CD burner. The PX-B310U supports DVD reading and writing in both the + and - formats, as well as reading and writing to DVD-RAM and Dual-Layered DVD discs.

The DVD+R DL test brings the Plextor PX-B310U back to normal levels. It's still a fast drive, but Asus and AOpen seem to have an edge when it comes to dual-layer burning.

Benchmarking with movies can be problematic - while the PX-B310U had no problem playing Blu-ray movies, benchmarks can at times conflict with the embedded DRM that's on Blu-ray discs, which we suspect what is going on here. Nero simply crashed repeatedly during this test, so there aren't any results that we can report.

Blu-Ray has gone portable!

From a performance stand point, the Plextor PX-B310U drive did quite for itself, frequently coming out as the fastest drive in several of the write and read speed benchmarks. There were a few hitches with read performance, but for the most part they didn't affect the drives overall speeds.

Blu-ray reading performance was similarly excellent, although it's important to stress that you'll definitely want a dual-core processor and at least 2GB of memory for playing back Blu-ray content smoothly. Anything less that and be prepared for skipping, buffering and hitches. If you have the luxury of choice, it's generally easier to go with a SATA-based internal drive, they just tend to be a bit more reliable than external USB options and circumvent a lot of potential system bandwidth bottlenecks.

At $220 CDN ($160 USD £125 GBP) the Plextor PX-B310U is a little pricey when compared to most external Blu-Ray drives. However that extra price is buying you a whole lot of convenience. The PX-B310U is an easy way to get Blu-ray onto PCs that could otherwise be difficult to upgrade, such as non-SATA PCs or laptops.

For computers that do meet the minimum requirements, it's pretty easy to get the PX-B310U set up and playing movies. Plextor bundles this external Blu-ray reader with Cyberlink's BD suite, as well as is own PlexUtilities software. The software has everything you need to read Blu-ray discs, burn CDs and DVDs, as well as a few utilities for creating CD labels.

Perhaps the best part about the Plextor PX-B310U is that it can handle pretty much every type of optical disc that's currently in use, and since it's external this mean it has a lot of versatility. It's a suitable solution for those who need to administer multiple computers and have lots of media coming in different formats. Although if you're just someone who wants to watch some Blu-ray movies without having to spring for a standalone player or crack open your computer case, the Plextor PX-B310U will work just as well.
