  • DNS Benchmark v2 is Finished and Available!
    Guest:
    That's right. It took an entire year, but the result far more accurate and feature laden than we originally planned. The world now has a universal, multi-protocol, super-accurate, DNS resolver performance-measuring tool. This major second version is not free. But the deal is, purchase it once for $9.95 and you own it — and it's entire future — without ever being asked to pay anything more. For an overview list of features and more, please see The DNS Benchmark page at GRC. If you decide to make it your own, thanks in advance. It's a piece of work I'm proud to offer for sale. And if you should have any questions, many of the people who have been using and testing it throughout the past year often hang out here.
    /Steve.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

    (You may permanently close this reminder with the 'X' in the upper right.)

It was a bit fiddly getting the system to recognize the USB stick for boot.
Otherwise, READSPEED ran with no problems. The HGST drives were read in a matter of seconds.
Spinrite 6.0 took over 50 hours to read and verify the same disks (level 4) on a different MB.
I never could get Spinrite properly to run on this system. DOS and Spinrite would load from a CD, but would never discover any of the drives.
I Can't wait for 6.1

MB has 32GB of ECC memory

Hi, thanks for posting your results! Interesting to have the CPU and mainboard info too! :)

Also interesting to see several identical drives' results together!

Those figures of 546 MB/s are the fastest I think I've seen!

I'm assuming that a lot of modern SSDs are maxxing out the SATA III bus, so that the top speeds that we're seeing are the limits of the SATA link. My Gigabyte GA-H87-D3H motherboard (with i7 4770S) caps out at 543.0 MB/s with my Samsung 860 Pro 512GB SSD, at least that's what I assume is happening.

Your system seems to have a slight edge! :)

It sounds like your system is AHCI. In which case, SpinRite 6.0 would not see any drives. ReadSpeed has no problem with AHCI, nor will SpinRite 6.1.
