Excerpt: Pioneer's DVR-212BK is one of only three internal DVD writers in this group with a SATA interface. Like the two SATA Sony drives, it doesn't come with any software at all. The DVR-212BK was the slowest burner in our CD-R test. With a speed of 23.44X, it was the only writer that couldn't exceed 25X. It fared better in our rewritable DVD tests where it was one of the fastest, writing DVD-RW discs at 5.5X and DVD+RW discs at 6.7X.
