    I had Acer Aspire 5749 with Intel 2nd Gen. Core i3 2330M and i want to replace my HDD with an SSD. The crystal Disk Info says that HDD transfer rate is SATA/300 or SATA 3 Gbps where as HWinfo64 Says that my notebook's motherboard has two SATA ports which are SATA 6 Gbps.
    I knon that if you use a SATA 3 Gbps HDD on SATA 6 Gbps port than speed will decrease to 3 Gbps according to device so it is possible that my HDD is 3 Gbps that is why Crystal Disk Info is showing that.

    Check screen shot for more details:

    What you think, is it has SATA 3 Gbps or SATA 6 Gbps ?

    Port is SATA3 (6Gbps), it's your HDD, which is SATA2 (3Gbps), hence the transfer is limited to SATA2.

    HM65 chipset supports up to 2 SATA3 ports plus up to 6 SATA 2 ports.

    Obsolete 5400 RPM HDD (suitable only for storage) is holding you back to SATA 2. Upgrade to better storage drives and experience the full speed and efficiency of SATA 3.

    SATA 2 or Generation 2 = 3.0 Gb/s transfer rate = 384 MB/s

    SATA 3.0 or Generation 3 = 6.0 Gb/s transfer rate = 768 MB/s

    Two SATA 3s side by side. Everybody's a wiseguy.
    .

    I meant SATA 3 (@6Gb/s)

    Well, it's simple - take SATA III drive. SATA II SSD are often more expensive, with less capacity, older technology NAND chips and controllers, which have more bugs and higher memory fail ratio with less read/write cycles etc.

    Also SATA-300 means SATA II, which might be limited by your HDD since HM65 chipset support SATA III interface.

    As a side note you will not notice any difference in real life between SATA II and SATA III unless you are going to do some large file transfers from folder A to folder B or some frequent video editing.
