SATA HDD connections

I have a Mother Board with a SATA 1.5G connector. Can I attach a HDD that is SATA 3G or 6G ?


Sorry I posted this in peripherals first. I'm new here as you can tell by my question.

  1. Yes, all versions of SATA (except the first for obvious reasons) are 100% backwards compatible.
  2. you may have to use the jumper on your drive to set it to sata 1

    So the 1TB drives will work with my MB just slower I assume.

    Thanks for the answer
  4. That depends on the drive (specifically the spindle speed 5400, 7200), You wont notice and real world difference though.
  5. Most Hard Drives aren't fast enough to saturate a 1Gb/s connection, let alone 1.5/3/6.
  6. It is supposed to work perfectly - the SATA 3.0 Gb/s or 6.0 Gb/s units are supposed to figure out what their controller is doing and adjust themselves to that automatically. In a few cases this fails. If that happens, check your HDD manufacturer's website for the way to force your newer SATA HDD to slow down to original SATA 1.5 Gb/s communication rate.
  7. Thanks for all the info and your time
