"A SATA 3Gb/s interface on the disc drive can increase system performance when the application takes advantage of the drive’s cache burst ability. In the case of writes, if the drive’s write cache capability is enabled, any write that fits in the buffer will be transferred at the full 3 Gbits/sec into the buffer. In the case of reads, caching helps when the data requested is small enough to fit into the drive cache and is present in the cache at the time of the request. That data will be transferred to the host at the full 3-Gbits/sec rate. In either case, the data must be in the form of small, sequential or near-sequential files, such as those found in some video editing applications. The reason: Small sequential or near-sequential file transfers require less mechanical movement or seek overhead and maximize caching capabilities of the drive. In these types of applications, SATA 3Gb/s drive interface rates can greatly increase performance."
