This model can burn DVDs at speeds up to 24x, along with a number of lower speeds including 22x and 16x, with read speeds of 16x for DVDs and 48x for CDs. That gives you a lot of control over how you write data to a DVD or CD, and 24x is as fast as you'll find for burning to a DVD. This model has a data buffer of 2MB, which is very good for an internal device. The software included with this model is decent but the fast speeds and good amount of buffer memory really make this a stand-out DVD burner. The burners ROM access time of 140ms from DVD is terrific and ensures quick access to any disc you place in it. ASUS designed this model to have pretty low power consumption, so it doesn't draw too much from your system's power supply and can help keep your electric bills down over the long term.
In terms of read/write speeds, this DVD burner is just about as good as any other model out there, capable of burning DVDs up to 24x but only has a maximum speed of 8x for dual-layer DVDs. That means it will burn slower than a drive that can burn dual-layer discs at 12x, which other models on the market can do. However, it can read DVDs at 16x and both read and write CDs at 48x. The buffer memory on this one is only 0.75MB, which is definitely less than it could be but still higher than some other models. While it still works just fine for burning discs, this difference could lead to issues with data corruption when burning a DVD. You get DVD-ROM access time of 200ms with this drive, which is decent but definitely about as slow as you should accept. The Nero software included with this model is excellent so if you don't have any burning software of your own, this is a great option that doesn't require the use of any other programs.
In general, this is a solid choice and a well-built DVD burner with a maximum burn speed of 24x much like similar models on the market and a maximum read speed of 16x. For burning to a dual-layer DVD it only has a maximum speed of 8x which is decent but certainly not remarkable. This model has 0.5MB of buffer memory, which leaves quite a bit to desire as this low amount of buffer memory can result in slow burning and a higher risk of data corruption, so keep that in mind if you plan on doing a lot of large-file writing and need fast, reliable performance every time. DVD-ROM access time with this model is excellent, at 145ms when using a single-layer disc. You'll probably want your own software with this one, and it can have some issues with specific programs, so be sure it's compatible with any software you plan on using.
There is a lot to like about this DVD burner, and while the DRW-24B1ST from ASUS is just a bit better, you get great options with this model that make it an excellent choice. It has a maximum write speed on DVD of 24x, with 12x when using dual-layer DVDs, which is very fast. 48x speeds when burning or reading from CDs is pretty common, but as good as you can find. The buffer memory on this model is a bit lacking, at just 0.5MB of memory, which diminishes how well this model deals with errors or data corruption while burning a disc. DVD-ROM access time with this burner is quite good, at 160ms, but just not quite as fast as the very best model from ASUS. This is a well-designed model, with dampers throughout the device to help absorb vibrations so overall operation is faster and helps eliminate errors caused due to disc or hardware vibrations.
In some respects, this model is almost comparable to the DRW-24B1ST from ASUS, but that other model remains superior in certain key ways. This burner has a maximum write speed for DVDs of 24x, though you'll probably use it closer to 12x, and a maximum speed of 12x when burning to a dual-layer disc. For CDs, it can read and write at 48x speed, which is pretty much the same as many other models on the market. One great aspect of this model is that ASUS includes a lot of environmental software with it. These utilities monitor when you're using the drive, and when you're not it can "power down" to save you money on your electric bill and reduce power draw by your computer. It has a 1.5MB memory buffer, which isn't as good as the DRW-24B1ST from ASUS, but is still excellent. Access time with this drive is great, with DVD-ROM access at 150ms, which is slightly slower than the DRW-24B1ST but still great. If you can deal with slightly less buffer memory, then the environmentally friendly software and additional features with this drive make it an excellent choice.
