WD360GD Raptors with the Marvell 88i8030-TBC PATA to SATA bridge chip, such as WD360GD-00FNA0 (December 2003) and earlier, are limited to UDMA 5 transfers. In Linux, "applying bridge limits" is displayed and then it allows transfers up to UDMA/100. In Microsoft Windows, they are reported as UDMA 6, but give a burst rate of 104 MB/s, while WD360GD with the 88i8030-TBC1 chip are reported as UDMA 6 and give a burst rate of 122 MB/s, close their theoretical limit of UDMA 6. Those Raptors limited at UDMA 5 were bought for SATA I 150 MB/s support, but they only support the legacy PATA UDMA 5 at 100 MB/s.
