    I have posted elsewhere [forums] on this issue and find sympathy & empathy but no answers, so I fear the answer is "yeah... gotta learn to live with that awful performance".

    If you are running a notebook with AMD chipset/mboard/APU and are getting GREAT SSD performance, please post your config and especially your DRIVERS. I have had a number of them, presently culled down to two of the older Zacate era [a G4 and a Thinkpad] and never seen even "good" performance on their SATA devices.
    The best performance I see is via the aged, unremarkable, generic MS-provided "Standard" SATA device driver.

    Post your AS SSD benchmarks, or other reputable mark, pls.

    I'm afraid this is just the way it is. SSD performance on AMD platforms lags significantly behind Intel. That's why professional SSD reviews are always done on Intel testbeds.

    AS SSD bm 'scores'? No.

    But some AMD APU based platforms have impressed me with the responsiveness/snappiness of certain tasks (browsing the O/S, for example) vs. same gen Intel based platforms. But ultimately (always) fail when real horsepower is required of the storage subsystem (not to mention the cpu, of course).

    Both get blown away in all aspects when compared with a current gen Broadwell platform (Intel based, of course).

    Same with the NVidia chipsets and platforms that I dumped so long ago. Buggy, inconsistent and always requiring attention to keep working as the years (and O/S updates) wore on. But, man, were they ever 'snappy', at the time. ;)

    The SSD performance I measured for the Samsung NP905S3G (AMD A6-1450 APU) was about what I would expect for that SSD. You will have to use Samsung's SW Update program to download the driver provided for that notebook.

    John, while that APU and SSD seems to be a match made in heaven, you have to admit that neither one could push the other for any real world workload (even back in 2013) that could challenge even yesteryear's better (then current...) SSD drives.

    A notebook with an AMD A6 APU isn't designed for heavy work? Do go on.

    thank you John for posting some numbers. my tester is another system so when I get time I'll run Crystaldisk there and post.
    but some of the numbers here are significantly diff http://www.guru3d.com/articles-pages/samsung-840-pro-ssd-benchmark-review-test,11.html
    definitely not an apples/apples comparative.

    the yangtze chipset is, I guess, 2 generations newer but dunno about the sata device in use there... I could never find a crisp answer to what SATA device they are actually using per-platform.
