When considering this model, you should really think about your needs in terms of performance versus portability. You won't easily find a faster external Blu-ray burner out there, let alone one that is even as fast as this model. It has Blu-ray write speeds of up to 14x, with 12x speed for dual-layer and 6x for triple-layer. If you plan on burning a lot of discs then this is very important to have because the difference between burning at 14x and 6x onto a disc is very noticeable, and only increases with each additional piece of media you create. There's also a 4MB buffer on this pick which is as good as it gets and helps protect your data as you burn to a disc. This model also uses a USB 3.0 connection which ensures that its fast speeds can be fully utilized when you burn a disc. It's a little bit large, so keep that in mind if you really need a slimmer device for optimal portability.
If you don't quite need the speeds of the LG BE14NU40, but you still want to burn or read from discs quickly, then this is a great option that outperforms a lot of other models. It has write speeds of up to 12x to Blu-rays, and 8x onto dual-layer Blu-ray discs. There's no triple-layer support, so keep that in mind if you need to burn your data on discs with three or four layers. The read speeds are also excellent, supporting up to 8x from Blu-rays, up to 16x from DVDs, and 40x from CDs. All of these terrific transfer rates would probably be wasted except this model also uses a USB 3.0 connection so you can take full advantage of them. You can also use USB 2.0 with this one, but you probably won't get transfers as fast through it. It has 4MB of buffer memory and comes with a stand that lets you use it in a horizontal or vertical configuration, making it a great fit for just about any workspace.
There is a lot to like about this model, though it sacrifices performance for portability, so keep that in mind. The maximum burn speed with this is only 6x on a single or dual-layer Blu-ray, though it can burn at 4x on a triple or four-layer disc. When burning to a DVD, it only goes up to 8x and 24x on a CD. All of these burn speeds are pretty low, especially compared to something like the LG BE14NU40. However, this model has 4MB of buffer memory so it can match any other external Blu-ray burner when it comes to preventing errors or data corruption due to low memory. Pioneer designed this model to have a very slim shape and size, with a slot-loading function that lets you easily transport it and set it up just about anywhere. The USB 3.0 support helps ensure you don’t get any bottlenecking from an older connection and it's a great choice if you need a portable option and do not plan on burning on media that is faster than 6x.
In terms of raw performance, this model is quite comparable to similar burners on the market. It has write speeds of up to 6x on single and dual-layer Blu-ray, up to 8x on DVD, and up to 24x on CD. This pick also has 4MB of buffer memory which is nice and USB 3.0 connectivity. USB 3.0 support would be a lot more impressive if it had faster write speeds, but at 6x you'd probably get about the same level of performance from a USB 2.0 connection. While a lot of other models on the market use trays that slide in and out to load or remove discs, letting you use them in either horizontal or vertical orientations, this one does not. This burner also comes with a hinged top that opens allowing you to manually place discs inside the drive; that feature alone is worth considering if you know you'll need to use your drive in a vertical position (since this one cannot be used that way) but you don't have to worry about the risk of a tray breaking down over time.
There's a lot to like about this external Blu-ray burner with a maximum Blu-ray write speed of 6x for both single and dual-layer discs, with 4x speeds for triple and quad-layer. This is something you should definitely keep in mind if you know you'll be burning a lot of discs, as your workflow could suffer while you wait for writing to complete. It only uses a USB 2.0 connection, but considering the rather slow speeds it offers as you probably won't find an issue with that. There are two integrated USB cables on this model, which makes it very easy to pack up and take with you, without ever having to worry about forgetting cables. Only one USB 2.0 connection is necessary for it to run, but you can use the second one as a “power boost” option to improve performance. Buffalo also offers a two-year warranty with this model, while most other options on the market have only one-year warranties to protect your investment.
In terms of read/write speeds, this is just as good as, or better than, any other model on the market. This model actually has write speeds on Blu-Ray of up to 16x on single-layer discs, 14x on dual-layer discs, and even up to 8x on triple-layer discs. Even other burners out there with multilayer support usually can't burn that fast, which truly sets this model apart. For older media, it has write speeds up to 16x on DVD and up to 40x on CD, which is pretty much as fast as you could want.
When reading from media, this model has speeds up to 12x from Blu-Ray, up to 16x from DVD, and up to 40x from CD. It also has 4MB of buffer memory which is comparable to most other burners and it provides excellent protection while writing data to a disc. You also get a good amount of software with this pick, including programs for playing Blu-ray and DVD movies on your computer in addition to burning both data and home video discs using this drive.
As you're comparing this model to the Pioneer BDR-2209, you should keep in mind that the differences between them are very minor. In terms of overall design, they are both very similar and excellent Blu-ray burners. This one would be the equal of any other Blu-ray burner on the market, if not for slightly lower multilayer burning speeds. It supports write speeds of up to 16x for single-layer Blu-rays, but only up to 8x for dual-layer, and 6x for triple-layer. While that's a fairly minor distinction, it's worth noting and ultimately can make a difference if you plan on burning a lot of multilayer Blu-rays.
For older media, it writes at up to 16x for DVD, and up to 48x for burning CDs. When reading from discs, this model can go up to 12x from a Blu-ray disc, up to 16x from a DVD, and up to 48x from a CD. This burner has 4MB of buffer memory, which is very good and BD-ROM access time of 180ms while the included programs are great for watching movies, making and burning your own movies, or backing up your data onto a Blu-ray disc.
Overall, this is a very solid drive that offers good speeds and a terrific amount of memory for buffering data as you read or write a disc. While this may not be the absolute fastest model out there, it'scertainly a very good one. It has write speeds for Blu-ray of up to 12x for single-layer and 8x for dual-layer, with burn speeds for DVD up to 16x, and up to 48x on CD. If this model had 16x Blu-ray burning, it would probably be the best one out there, but it just can't match the speed of some other burners on the market.
This drive has read speeds of up to 8x for Blu-ray, 16x for DVD, and 48x for CD, which are quite good. However, what really makes this a great drive, is that it has 8MB of buffer memory which is double the amount in pretty much any other model you're going to find. That much memory really helps prevent errors as you burn data to a disc as well as ensuring smooth playback. The BD-ROM access time on this burner is rather high at 250ms. This model includes the same great software as the ones from Pioneer and LG, but if you want the fastest speeds possible then this one just falls a bit short.
If you're looking for absolutely the fastest drive on the market, then this one is definitely not for you. The read/write speeds on it are respectable and should be fine for most situations, but the difference is noticeable compared to faster models on the market. When burning to a disc, this drive supports speeds up to 6x on Blu-ray, including both single and double-layer, up to 8x on DVD, and up to 24x on CDs. That's less than half the speed that you can get from some other burners out there, especially the Blu-ray write speed.
Read speeds on this model are similarly low with 6x coming from Blu-ray, 8x when reading from DVD, and 24x from CD. 4MB of buffer memory is quite good and will help protect your data during burning. The 120ms BD-ROM access time is about as fast as it gets, so that's one very strong point for this model. If you have a full-size computer then you can definitely have some better options but for a notebook or laptop that needs a slim drive this is a terrific choice.
There are some great technical aspects of this Blu-ray burner with a maximum Blu-ray write speed of 14x with options for 12x, 10x, and lower, though dual-layer write speeds with this one only go up to 12x. It has 4MB of buffer memory, which is what you will find on most of the other best models out there, which helps keep your data free from errors or possible corruption while you're burning.
The BD-ROM access time with this burner is 180ms which is quite good, but certainly not the absolute fastest time on the market. LG includes some very nice software with this drive for backing up your data or burning media and it can even play 3D Blu-rays. All of this adds up to a great burner that is definitely one of the best on the market, but nothing quite pushes it to being the best of the best.
