    Hello everyone,

    I recently bought a Samsung 840 Pro 256 GB ssd that I use use as the sole harddrive on my Lenovo Ideapad Y580. Using the Samsung Magician tool, I have the following benchmarks:

    As you can see, it seems my random read/write speeds are lower than they should be. Anything I can do to improve these numbers? Are they way lower than they should be? Any advice would be appreciated.

    Go into windows power options, switch to high performance, go into advanced power options, change both minimum & maximum processor state to 100%, and rerun benchmark. If you're still not seeing improvements or numbers that you like, it's related to power saving features and/or chipset limitations on laptops.

    Edit - In addition to what I mentioned above, I'd also run Prime95 on a single thread while benchmarking. You should see much higher scores by doing this.

    Edit 2 - I'm sure you already realize this, but the above is not a permanent solution, but rather something you can do temporarily to improve benchmark numbers :)

    All laptops will bottleneck an SSD's random performance due to the CPU C-state switching which is much more aggressive than desktops (which these SSDs are normally reviewed on).

    Almost all SSD reviews are not only done on desktops with high end hardware you'll notice also the drives are empty of data and tested from a different boot drive that's in safe mode.

    Anyone use their SSD in Safe Mode and not as the primary boot drive.I think not but that's the way they are reviewed.

    Some reviews are done with custom software that no one other than the reviewer has.

    Also missing are screenshots of the benchmarks of the drive being reviewed.

    Everything now is graphs,graphs and more graphs.They're OK for comparing to previously tested SSDs but the drive being reviewed IMO needs to have benchmark screenshots.

    I like to see an Anvil Storage Utilities screenshots of the drive being reviewed with both 0Fill and incompressible.

    A picture is worth a thousand words.
