    This new 64-bit build is working great here in my testing so far. :thumb:

    @angstrom - the 64-bit version works just fine in a PE10 configuration, should work without issue in PE3.1 or PE5.

    Thanks much for the effort!

    @angstrom - quick question. Does this benchmark run under Windows XPx86? I've tried it a coupla times and it fails with msg in the LOG... which I can't seem to find anywhere :confused:

    Any help, greatly appreciated...

    I don't think so.
    website: "Requires: Windows Vista or newer"

    Never tested it on XP to be honest. Tried just now and it fails in NtSetSystemInformation() call when trying to clear the standby list (you can see the log by starting the program with "-d" switch). This effectively means that there's no reliable way to purge the file system cache before testing, so the results will be skewed and the whole thing will be largely pointless.

    That said, you should be able to switch off cache purging by changing test type to Custom, and then setting "Cache control" to "Leave cache alone". That's in theory. In practice however you need to set it to the exact opposite - "Purge cache before each test" - because I messed up and put options there in the reverse order. I'll patch it tomorrow.

    Edit: regarding this -
    To be more precise, any tests of the "buffered / cached" variety will be pointless. The "unbuffered" bunch should be OK... at least in theory.

    Thank you for making this tool available. On a two year old 250 GB M.2 drive w/98% drive life remaining, in Good health via CrystalDiskInfo. Results are somewhat compatible with Passmark's https://imgur.com/QWgX2XM Disk Mark, read status, though not write. The driver and firmware are the latest by Samsung but I believe the write speed is rather below what is advertised (1800). Things are snappy regardless so I think it's got a ways to go.

    Edited for clarity. Edit: searched for below-advertised write speed for the Samsung EVO 960 but haven't come up with anything useful (yet).

    • Volume serial number is now masked out from the screenshots.
    • Also, this update pulls in all the changes in libraries it shares with bvckup2 that accumulated since August last year.
