Samsung's New SATA II Hard Disks Offer 3 Gbps I/O

Samsung Electronics began shipping the first Serial ATA II hard drives offering native 3.0 Gbps I/O transaction capabilities in addition to Serial ATA Native Command Queuing. The 3.0 Gbps speed doubles the 1.5 Gbps data transfer rate of current Serial ATA hard drives. Serial ATA also allows for the "daisy chaining" of drives via sleek and slim cables, so that systems can be expanded by simply adding additional drives.


Samsung's family of Serial ATA II hard drives include an 80 GB model ($93 estimated street price), 120 GB model ($120) and a 160 GB model($150). All feature a 7,200 rpm spindle speed, an 8.9 millisecond average seek time and a 8MB cache buffer.
