| 1318886 | 2012-12-18 03:53:00 | Hi. I am confused between the SATA3 hard drives and the Sata2 hard drives. The reason so, is because I have recently bought a brand new motherboard, and it supports 1x SATA3 HDD, and the remaining 4 are SATA2. I have brought a brand new SATA3 HDD (500GB), and thought to buy another hard drive that is SATA2, since my mother board only supports 1x SATA3 HDD. I've looked on TradeMe, Pricespy, Sella NZ, PriceMe and it seems that there are more SATA3 hard drives than SATA2 and also cost less than the SATA2 types. So I am a worried, having spent money on what I thought would be a good investment for me now, since its been 14 years I have upgraded and feel like I have wasted my money seeing there are less SATA2 hard drives available than I would of thought, since using the IDE Hard Drives. Anyway, whats the big deal about SATA than IDE? My question is, If I buy another SATA3 Hard Drive, would this work on a SATA2 port? Or would I need to buy another motherboard? Cheers Motherboard type: Gigabyte B75M-D3H rev1.1 |

| 1318887 | 2012-12-18 04:17:00 | SATA 3 drives are backwards compatible with SATA 2 motherboards; the drive will simply run at the slower speed of SATA 2. | pcuser42 (130) | ||
| 1318888 | 2012-12-18 05:19:00 | Also you can add more SATA3 ports with a plug in PCI card. Can't comment on how its speed would compare with the MOBO port, which should be quicker, but dunno how much quicker. |

| 1318889 | 2012-12-18 05:35:00 | SATA3 will work with SATA2 just theoretically slower. Theoretically b/c I have a SATA 2 motherboard, I have both SATA1 and SATA2 HDDs. No speed diffrences. Unless maybe if you go with stripe RAID or Solid State HDDs ;) | Nomad (952) | ||
| 1318890 | 2012-12-18 08:31:00 | The only thing that maxes out sata2 is ssd's If you just buy another sata3 hd it will plug into sata2 fine and be as fast. |

| 1318891 | 2012-12-18 09:35:00 | Even the high speed hard drives have transfer rates barely faster than the top speed of the original SATA. SATA2 and SATA3 will only make a big difference with SSDs. SATA is generally backward and forward compatible (though some drives need a limit jumper), unless you have some weird bug with a certain drive \ chipset combination or such. |

| 1318892 | 2012-12-19 10:34:00 | Thanks all for your help. That was really helpful. I have one more question though. Do I need to make any configurations between master, slave or cable select if I have two or more SATA drives in my computer, like when I used to use jumpers with IDE hard disks? |
undiejuice (16495) | ||
| 1318893 | 2012-12-19 13:37:00 | No, there are no master\slave setting jumpers for SATA, because you can only have one drive per SATA port\channel anyway. Some SATA drives do have jumpers for other things though, like forcing slower link speeds, configuring 'Advanced Format' (4k sector) drives etc. |

| 1318895 | 2012-12-21 07:55:00 | ATA 3.0 Gb/s (SATA 2) and SATA 6.0Gb/s (SATA 3) refer to the speed of the link between the drive and the motherboard. However, the best hard drives reach about 210MB/s in best scenarios. SATA 3.0Gb/s is plenty sufficient to handle that and for hard drives, SATA 6.0Gb/s does not offer any recital advantage, since the hard drives can’t even max out a SATA2 3.0Gb/s link." I tried pointed for some really testing data but couldn't come up with any. I keep the site booked marked as they do have good in sequence on computer part. I hope this helps. |
