Superb Performance of SATA3

How fast of the latest hard drive Serial ATA (SATA) interface can offer? The world’s largest manufacturer of hard drives and storage solutions, Seagate, has collaborated with the microprocessor manufacturing leader Advanced Micro Devices (AMD) at the Everything Channel Xchange Conference to demo and present to the public the superb performance of latest SATA3 which can offers speed up to 6Gbps or 600MBps, almost double the speed of current SATA or SATA2.

The new SATA3 (or SATA 6Gb/second) was developed by the Serial ATA International Organization under the Serial ATA Revision 3.0 specifications. This high performance interface is good for bandwidth-hungry desktop and laptop PC applications including gaming, streaming video and graphics multimedia. Seagate has highlighted in its statement the new SATA3 will be backward compatible with the existing SATA and SATA2 interfaces and it share the same cables and connectors. SATA3 enhances power efficiency, improves Native Command Queuing, a SATA feature, increase overall system performance and data transfer speeds.

SATA3 will be practically useful for bandwidth-hungry desktop and laptop PC applications including gaming, streaming video and graphics multimedia. Seagate reveals that this new SATA3 is in the final phase of development and users can only expect the first SATA3-based hard drive by the end of the year.

Hard drives? I would have thought SSDs would benefit more from this. I have read in Newegg reviews (of SSDs) that just two SSDs ( of around 150-170MB/s each) in RAID0 can saturate the SATA II controller bandwidth. Does even Velociraptors reach these speeds?

i think you are not getting the point.

we are here talking about the new technology, The new SATA3 (or SATA 6Gb/second). can a velocity raptorr(SATA-II) outperform SATA3, if the burst rate of velocityraptor(SATA-II or Sata 3Gb/sec) would be 300MBps, so how come it will out perform buddy. So how come it will out perform?..

this is something The new SATA3 (or SATA 6Gb/second)

now we can xpect faster load times in games.

SATAI/II/III are specifications that indicate the data transfer bandwidth available to storage devices.. meaning that the devices CAN transfer data at that speed IF they are not bottlenecked by anything else.

it does not mean that the device is currently working at that speed.. in fact the fastest HDD available now.. the velociraptor has an average read speed of abot 105 MB/s, while for that in RAID 0 is around 150 MB/s. So there is currently no hard disk in the market that can saturate even the SATA bandwidth, let alone SATA II.

SSD disks on the other hand are different... but they are insanely expensive.
