    sata 6.Gbps drives

    crmark

      My intel dp67bg extreme mobo has Two Serial ATA (SATA) 6.0 Gb/s interfaces and Four internal SATA 3.0 Gb/s interfaces.

      Should I look for samsung drives that have high transfer rates. Would it be wise to put two of these on RAID 0?

      How will they compare to WD velociraptors @10k rpm?

          for the most part you can ignore it the benchmarks differnce between Sata 600 and 300 is non existant

          however if buying new drives you want 64meg cache which pretty much means sata 600 at this point.

          Raid 0 is great but you need 2 equal sets

           

          Raptors(new ones) will give better performance but may be over kill and the differences are not all that much

          here are some benchmarks

           

          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 Rqaid 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

            Wow thank Scott.

            I presently have 1 WD velociraptor 150GB @10k rpm. Im a little slow...

            For instance when you say "

            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

            "

            Does it mean you get a speed of 112MB/s or are you mentioning what GB drives should be combined together on RAID?

              those are the measured benchmarks for the listed drive configs

                Scott, I assume that the single number is the read speed and the you are using HD Tune Pro for the benchmarks--is that correct?  It appears that a 32 GB Seagate is slightly faster than the 64 GB WD.

                  So I took Bills advice and got myself 2x 1TB HDDs with 32MB cache that run at 7200RPM, I also have 1x WD velociraptor 150GB HDD that runs at 10000RPM.

                  Im wondering what would be better? leave my WD HDD as the boot drive and run the other two in RAID 0?

                  Also I haven't opened up a CPU ever, I'm wondering which ports I should plug them in to get them to work at RAID 0 before I enter BIOS? My baord the intel DP67BG has 4 SATA ports  (3.Gbps ) and 2 SATA ports that are (6 GBPS).

                   

                  Thanks

                    Raptor as OS

                    Again you need 2 x raid 0 sets  or 2 non raid drives.

                     

                    You never want to read and write from the same drive(s) unless it’s a 8+ drive array

                      Thanks again Scott. So I've installed my Drives, set them up as RAID.

                      I had to install WIN 7 again, it crashed for some reason when I added 8GB RAM and the drives.

                      SO C drive is my 150GB Velociraptor.

                      Ive set up the other drives but WIN 7 hasn't recognised them. I'm installing all the updates. I should hopefully be able to see them after the updates are installed.

                       

                      Question now is when I run AE & PREM. Which drive should I use as scratch disk? Which drive do I save my files in? Which drive do I export the output to?

                       

                      Thanks
