Are On-Board SATA 6Gbps Ports Fast Enough? | bit-tech.net
Bit-Tech UK said:If you’re perfectly happy with your motherboard but want to add a couple of SATA 6Gbps ports to your system, there’s a relatively cheap and brutally fast way to do so in the form of Highpoint’s Rocket 620 add-in card. This unassuming little card is home to the same Marvell 9128 controller that many Intel boards use.
However, as the card plugs into a PCI Express slot, it bypasses any Southbridge-related bottlenecks and can write and load data at breakneck speeds. In the 1MB and 4MB read tests, the Rocket 620 was 20MB/sec faster than any other SATA 6Gbps controller we tested.
