    SSD vs HDD Linux performance compared - minimal advantage at best?

    dixter1 - Thanks for the helpful information. I ended up moving the SSD to the other build, the one for a new Windows 7 machine, which I run separately, not as a virtual machine. The Windows 7 boots VERY fast, just a second or two. I like that a lot, but it's hardly worth the extra cost. I...

    Linux SSD vs HDD performance - minimal SSD advantage at best?

    That's what I repeatedly read in those glowing reviews I mentioned. But it misses the point that caching overrides that performance difference much of the time. I don't think this is "poorest circumstance" at all. These are not artificial tests that I devised. Yes, two of the tests repeatedly...

    Linux SSD vs HDD performance - minimal SSD advantage at best?

    That's a great question. Assuming the test results I presented are correct and the SSD is wasted expense, I guess the answer is: 1) I let my false hopes get the better of me, based on the many glowing SSD reviews I saw that said adding an SSD would be the best way to improve performance, and...

    Linux SSD vs HDD performance - minimal SSD advantage at best?

    I don't just "want to argue with anyone that tries to help". I want to have a discussion, and figure out if I am doing something wrong in my tests or missed something. And if the tests are correct, it's something that might be helpful to others. Am I supposed to just accept everything you (or...

    Linux SSD vs HDD performance - minimal SSD advantage at best?

    Thanks much for doing the tests. That agrees with my "time cat bigfile > /dev/null" test with a 4 GB file (BTW, I may have misread, I think it was 0.4 GB but the principle is the same) after a fresh boot, where SSD is 0.76 and HDD is 3.83 seconds. But the second time (file is cached), the times...

    Linux SSD vs HDD performance - minimal SSD advantage at best?

    I greatly appreciate your comments and suggestions, even though I don't think they hold water. This is very helpful getting feedback on this forum. No, I did not secure-erase the SSD before partitioning. I marked the entire SSD as one partition. I boot from the HDD, the SSD is not bootable as I...

    Linux SSD vs HDD performance - minimal SSD advantage at best?

    Thanks for the response. The HTML files are each around 30 KB size. There are about 300 of them. Each one is converted through a series of about 8 steps. At each step, the script saves an intermediate file. So there a lot of file reading and writing. You're right the files are not huge. You...

    Linux SSD vs HDD performance - minimal SSD advantage at best?

    I recently posted a similar message to the storage forum, did not get any replies. Here is a modified version. I am hoping some linux experts can either confirm my findings, or suggest what I am missing. ************** Introduction: I recently built a system: Supermicro X10SAE-O ATX DDR3 1600...

    SSD vs HDD Linux performance compared - minimal advantage at best?

    The other thing I should mention is that the 250 GB SSD has about 50 GB of files on it. So there is not a performance problem from the SSD approaching being full. I look forward to any responses, anyone else who has done other real-world tests, anyone who might point out something I'm missing.

    Could someone explain vcore = 1.75 for i3-4130

    So is the issue that "superdoctor iii" and "bios health status" are reporting the VRM / FIVR input voltage, as explained by InvalidError, instead of reporting the internal cpu voltage? I don't see any other cpu voltages reported, do not see a way to show the internal voltage. I do see the RAM...

    Could someone explain vcore = 1.75 for i3-4130

    I have an i3-4130 with a supermicro x10sae motherboard. I am not overclocking. The motherboard comes with superdoctor III (windows 7) which reports lots of status information. And the BIOS has a hardware health tab. superdoctor iii says that the vcore voltage "low / high limits" are 0.60 to...

    Professional Workstation with ECC

    I never thought of that. "make -j" "Specifies the number of jobs (commands) to run simultaneously." I use make to build lots of different things. So it sounds like that might make full use of the extra cores, as you suggest. There is also a "make -l" option to keep starting new jobs as long...

    Professional Workstation with ECC

    The Cooler Master case has somewhat a problem with right-angle SATA connectors (does not fit well), according to several newegg reviews. The asrock C226 WS has right-angle SATA connectors. So I switched to the supermicro X10SAE-O motherboard, with straight SATA connectors. Current config...
