Pros: The Quantum Blu-ray Media was able write at a speed at 12x speed, which I didn't anticipate. I tried, 4x, 6x and 12x and they all worked fine. Out of the first 8 I burned the media was able to write without any issues.

Cons: None.

Overall Review: These worked well with my ASUS USB 3.0 12X Blu-ray Burner Model BW-12D1S-U/BLK/G/AS without any issue. With this media, I was able to write 6 in a row at 12x speed with no issues.

Pros: This drive is extremely fast. The package was delivered on time. The drive installed like a charm. The drive is quiet for its speed and power. That data transfer speeds are impressive. This drive doesn't allow me to do anything more than my old drives did, but it decreases the lag that was in applications at load time, and improves my experience.

Cons: The drive is an OEM, and the packaging that it was delivered in was the drive in a plastic cover in bubblewrap, insided a peanut filled packing box. This might seem adiquate, but I would still prefer an anti-static bag.

Overall Review: For some reason this is my first OEM drive that I have bought for personal use, and I am really pleased with its performance thus far. The warranty helps to keep me asleep at night, and overall for the money and performance this is in my opinion the best option for a single drive or for any mid sized raid application.
