    Disk Benchmark Results - Please Decipher?

    alexdejesus Level 1

      I know I'm  imposing, but I don't have anything to compare my results to and I don't really understand the measurements in these tests. I'm certain my drives are bottlenecking me big time. Do these numbers look  appropriate for the types of drives and connections? I tested my internal drives with Samsung Magician and then all of the drives, including externals, with Crystal Mark.

       

      My system is Sandy Bridge w i7-2600k processor and 32 GB RAM. GTX-580 video card. I'm currently editing HDV, but expect to upgrade cameras and format this year and need to know where to focus my system upgrades.  Thanks.

          To give you something to compare with, here are some results from my own system.

           

          Corsair Performance Pro SSD:

          CrystalDiskMark D.png

          In comparison, your SSD is significantly slower.

           

          Single Seagate Constellation ES:

          CrystalDiskMark F.png

          Your first raid0 shows understandably better figures than this single disk, but your second raid0 is only slightly faster than this single disk on sequential results. What surprises me is the disappointing random R/W results on both raid volumes. My single disk does a better job at that.

           

          My large 3 x 7 R3 striped to raid30, Constellation ES:

          CrystalDiskMark E.png

          These figures are of course incomparable, because of the size of the array.

            And I should have mentioned I'm using the onboard SATA controller. Is there an affordable controller I should look into?

            I'm wondering how the limitations of the motherboard affect drive performance. The SSD and my 1st RAID are about a year old. The rest of the drives are more dated. I have not been following the newer models.

              I wonder if you have processes running that influence your random R/W speed, like anti-something software, compression or indexing,  or disk optimizers that can reduce your R/W scores. Did you optimize your disks before running Crystal Disk Mark (I did not...)?

                Samsung Magician has a performance optimizer and an OS optimizer that recommended certain things be shut off: "Superfetch," a Defragmenter, and an Indexing service. There's a thing called 'System Mechanic' that monitors certain things. ASUS has a system monitor as well. I'm sure I have other background services, but I'm not sure which ones I can turn off. I usually disable the Norton when I edit, but not sure if it makes any difference. Compression and indexing have been off. 11-February-2013_07-45 SSD Kingston.png11-February-2013_07-49 D Drive.pngI'm concerned about the drop in R/W on the 4TB RAID about half way through the benchmark11-February-2013_07-52 E Drive.png

                 

                I realized I had the wrong SSD installed. I put Tte Kingston HyperX so I could format the Patriot Wildfire, and never re-installed the Patriot which is supposed to perform better. I cloned and installed the Patriot, and it scored about the ssame as the other SSD.

                 

                I am still concerned about my RAIDs, thinking I should re-configure. The slower RAID consists of SATA 2 drives. I have not checked out the latest SSDs or spin drives in a while. I moved the pagefile from the slower RAID 0 to the SSD.

                  My BIOS is not in 'AHCI' mode - because I have RAIDs setup. Is that why I'm not getting the performance from my SSD?

                    Harm Millaard Level 7

                    Not using AHCI mode used to be the best setting on older motherboards, but with new motherboards and up to date BIOS versions that may no longer be the case. Try enabling AHCI and report if that gives any improvement.

                     

                    The spikes in your HDTune charts suggest background processes that disrupt a nice non-spiked line like this one:

                     

                    Areca transfer rartes.png

                    BTW, if you post your images with the HDTune results, can you include the Block Size Test, like above?

                      I once accidentally switched to AHCI and lost my RAIDs. I think I may have to format and re-install Windows. That's not going to happen today

                       

                      Thanks, I'll go hunting for background processes
