can a motherboard that list SATA 3Gb/s support the speed of a faster hard drive?

can a motherboard that list SATA 3Gb/s connectors support the speed of a hard drive with a 6Gb/s transfer rate?

    SATA-III HDs are nowhere near saturating the SATA-II bus (speed wise), so you'll achieve the same speed whether you attach the HD to a SATA-II or SATA-III controller.

    +1  presently there is no gain with Sata 6GB over sata 3gb
    the sata 6gb are nice due to the added (64meg) cache and yes they work on Sata 3GB

    syntheticpop,

    To answer your question: No.

    A SATA 3Gb/s port can not support the speed of the 6Gb/s hard drive.  As Jim pointed out, the 6Gb/s hard drive will run at the 3Gb/s speed when plugged into a 3Gb/s port. 

    If you begin to connect SSDs or setup a RAID, you can then see a benefit to using SATA 6Gb/s ports.

    SSD? there is no SSD that actually hits stated numbers including the new Crucial 300. in fact 285 was about it with that drive and the Mushkin did 275. (reads)
    the Mushkin did better on writes. (yes i know what the review sites say)

    as far as raid it takes an 8 drive raid array to finally see the advantage of sata 600 and that also requires an expensive controller.
    here are some numbers

    WD 1 TB 64 meg Cache Sata 600 Drives
    Intel onboard Controller
     Single drive - 112MB
    2 Drive Raid 0 - 196MB
    4 Drive raid 0 - 364MB
    3 Drive Raid 5 - 108MB
    4 Drive Raid 5 - 296MB
    Marvell 6G controller
    Single Drive  - 111MB
    2 Drive Raid 0 - 215MB
     
    Intel SAS RS2BL080 8 Port controller with 512 DDR2 Ram.
    Single Drive - 111MB
    2 Drive Raid 0 - 215MB
    4 Drive Raid 0 - 429MB
    3 Drive Raid 5 - 219MB
    4 Drive Raid 5 - 315MB
     
    Seagate 1TB 32 Meg Cache Drives
    Onboard Intel Controller
    Single Drive - 103MB
    2 Drive Raid 0 - 206MB
    4 Drive Raid 0 - 395MB
    3 Drive Raid 5 - 202MB
    4 Drive Raid 5 - 299MB
     
    Intel SAS RS2BL080 8 Port controller with 512 DDR2 Ram
    Single Drive - 101MB
    2 Drive Raid 0 - 199MB
    4 Drive Raid 0 - 399MB
    3 Drive Raid 5 - 204MB
    4 Drive Raid 5 - 310MB
     
    Intel SAS RS2PI080 8 Port controller with 512 DDR2 Ram
    8x WD VelociRaptor 600 GB, SATA 6 Gb/s, 32 MB Cache, 10,000 RPM
    8 Drive Raid 5 - 745MB/s read 735MB/s Write
     
    8x WD 1TB SATA 6 Gb/s, 64 MB Cache, 7200 RPM
    8 Drive Raid 5 - 703.8MB/s read 670MB/s Write

    Future technology generally builds upon existing technology.   We should expect to see SSDs that hit close to the 6Gb/s transfer rates in the near future, at least at the read level.

    But for now, as Scott pointed out, it takes a large RAID to really reap the benefits of SATA 6Gb/s.
