    HDD Choice


      I've purchased an i7-970

      based computer. To reduce cost for now i use old owned hdd :

      HD Tune: ST3160811AS Benchmark

      Transfer Rate Minimum : 36.2 MB/sec
      Transfer Rate Maximum : 75.7 MB/sec
      Transfer Rate Average : 62.0 MB/sec
      Access Time           : 17.1 ms
      Burst Rate            : 97.1 MB/sec
      CPU Usage             : -1.0%


      HD Tune: ST3160811AS Benchmark

      Transfer Rate Minimum : 35.7 MB/sec
      Transfer Rate Maximum : 74.8 MB/sec
      Transfer Rate Average : 61.5 MB/sec
      Access Time           : 17.3 ms
      Burst Rate            : 97.0 MB/sec
      CPU Usage             : -1.0%


      HD Tune: WDC WD800JD-00LSA5 Benchmark

      Transfer Rate Minimum : 24.7 MB/sec
      Transfer Rate Maximum : 58.2 MB/sec
      Transfer Rate Average : 48.5 MB/sec
      Access Time           : 14.5 ms
      Burst Rate            : 131.7 MB/sec
      CPU Usage             : -1.0%

      I would like to know which hdd is the less worth to be OS&program disk ?


      Note: I'm thinking to change hdd few month: fist priority must be OS & program disk for which I'll choose WD 150Go Velociraptor.

      Which hdd could scarth and project / Media be ?

          For the time being, it does not really matter. All your disks are pretty slow for todays standards and your current solution is a temporary one anyway. When you get a Velociraptor for a boot disk, you need to do a fresh install anyway. With the i7-970 all your current disks will be the main bottleneck in terms of performance and speed. Given the HDTach results I would choose a Seagate for OS & programs for the time being.


          This is hindsight and does not help you, but maybe it will help others. Had you gone for a i7-920, which has a lower clock speed to start with, you could have gotten a more balanced system by using the savings on the CPU for more and faster disks and making your editing experience more pleasant.


          To see where this new system is in terms of performance now with your old disks, run the http://ppbm4.com benchmark and report the results to Bill, then repeat that when you have the new disks and see what it does to your performance.

            Thanks Harm for the answer,


            I know that it isn't a good solution, but next month, I would have Velociraptor, and in 3 months I could buy 2 decent hdd.


            And ppbm4 can show the progress !!!

              To me those numbers look like you have tested them with a USB controller.

                Bill, you are very positive about USB. Average rates of 50-65 MB/s looks to me as either IDE or pretty old SATA disks with limited cache or a pretty high fill rate.

                  They are pretty old SATA disks.


                  For project and output disk I planned to purchased 2 Samsung Spinpoint F3 1 To disks. Is the better choice ?

                    There are IMO 3 good choices and the final choice could be based on an attractive sales price. They are Samsung F3, Seagate 7200.12 or WD Caviar Black.
