Happy2Play 8142 Posted July 5, 2017 Share Posted July 5, 2017 (edited) is the difference down to the speed of the cpu's - intel vs AMD (old!) I would guess the amount of data, 18TB vs 36TB. Both seem to perform about the same for old technology. http://cpuboss.com/cpus/Intel-Xeon-X3450-vs-AMD-Phenom-II-X4-955 Edited July 5, 2017 by Happy2Play Link to comment Share on other sites More sharing options...
PenkethBoy 2063 Posted July 5, 2017 Share Posted July 5, 2017 i made a mistake and added lots of photo's to my "extrafanart" directories and that kills the scan speed went from a few minutes to over an hour also where the data is on a disc can have a large effect - fast on the outside edge and slow in the centre DP is not raid so the speed you get is mainly down to the native speed of the disc Link to comment Share on other sites More sharing options...
Happy2Play 8142 Posted July 5, 2017 Share Posted July 5, 2017 So in theory I should get better speeds if I had matching drive speeds. I have a mix of Seagate, Western Digital, and Hitachi drives (5400, 5900, and 7200rpm). Link to comment Share on other sites More sharing options...
Guest asrequested Posted July 5, 2017 Share Posted July 5, 2017 Seek times will definitely vary between those drives. All my pools have matching drives, especially my movie pool. For that pool they're all HGST 7200 rpm Link to comment Share on other sites More sharing options...
PenkethBoy 2063 Posted July 5, 2017 Share Posted July 5, 2017 in Scanner from stable bit - if you have it installed - you can do a burst test on a drive to see how fast it is or a better option would be HDTune which does a read test across all sectors and gives you a max and min - does take a few hours to run - although you can run multiple copies at the same time to test multiple drives IIRC when i did this on my HGST 4tb drives it was 170 MB/s to 130 MB/s from outside to inside Also size matters - bigger disk usually more buffer - so generally faster - have a Seagate Archive drive 8TB and that will do over 200MB/s Faster drives also have better seek time so 7200 better than 5400 etc And controllers will have an effect...... Happy - one thing to be careful of in the future as and when you move away from WHS to say win 10 - Rocket Raid controllers do not work well with Windows - had three 2720 and all they did was lock the system up with DP - driver/bios issues - this is with two different motherboards etc - very reproducible when put under load Link to comment Share on other sites More sharing options...
Happy2Play 8142 Posted July 5, 2017 Share Posted July 5, 2017 Don't really know know how useful the burst test really is. SSD 461MB off motherboard 5900 250MB RR2720 7200 450-471MB RR2720 Depending on Manufacture Drives on the RR2760 were 25-50MB slower. Transfers from outside saturate my gigabit connection at 113MB and Pool to SSD about 137MB and SSD to Pool about 120MB. @@PenkethBoy - Thanks for the warning for when I do upgrade.
