Samsung 840 Pro 256gb ssd slow on my build? Help!

Hello, this is my build

Gigabyte 990FXA-UD3 motherboard
AMD FX 6100 Processor
Samsung 840 Pro SSD

(will post additional components if needed)

For some reason, my AS SSD benchmark ratings are slow. My spec sheet says all of my SATA ports are 6 gb/s. I'm not sure if I'm using AHCI? Also I don't know what else I should be checking? Can someone help me/troubleshoot me?

Here are my ratings:

  1. Your read / write benchmarks aren't that bad, but could be a little higher. Restart and go into you BIOS. (Usually you press the delete button slowly, but repeatedly until you see the BIOS screen ) In the advanced tabs find the Sata configuration and you will find your choices for IDE, RAID, and AHCI. Most newer MB's default to AHCI, but you should check anyway. Does your system feel fast and responsive, programs like browsers and e-mail clients should load instantly, almost before you let go of the left click on your mouse. Have you tried moving large files. You should max out your HD's transfer rates.

    Operating System: Windows 7
    1. Ensure your SATA ports are configured to use AHCI mode in BIOS

    This is the very first step to ensuring that you’re getting the most from your SSD. SSDs using AHCI (Advanced Host Controller Interface) SATA mode will perform much faster than SSDs in the old IDE (Integrated Drive Electronics) SATA mode, so this should definitely be the first thing you do when you after physically installing your new SSD. Unfortunately, there’s no universal way to do this, but be sure to check out your motherboard manual on how this is done. Do make sure to do this PRIOR to installing Windows!

    If you’ve already missed this step, there’s a pretty easy way to do this in Windows.

    Click Start
    In the Search bar at the bottom type in “regedit”
    Browse to “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci”
    Right click on “Start”
    Click Modify
    Change the value data to “0?
    Restart your computer
    Go into your BIOS/UEFI and set your SATA Configuration to AHCI


    2. If your SSD supports it, enable TRIM!

    You may be asking yourself what is TRIM? Well, TRIM is a series of commands that are sent back and forth between the SSD and the rest of the computer that tells the SSD when files are no longer being used so that they can be deleted or cleaned up. These files are usually files like temporary internet files, so no need to worry about losing anything important!

    To enable trim it’s pretty easy. Just a simple command through the command prompt (CMD), but first we want to test and see if it’s enabled. Click Start, in the search bar type “cmd” and right click your search result and click “Open as Administrator”. Once that box is open, type “fsutil behavior query DisableDeleteNotify” without the quotes. If you get DisableDeleteNotify = 0 then TRIM is working. If you get DisableDeleteNotify = 1 then we need to enable it.

    To enable it simply type “fsutil behavior set disabledeletenotify 0? without the quotes and restart your computer! It’s that simple. That said, most Windows 7 users will find that TRIM is automagically enabled, but just in case it’s not, be sure to do it!
    3. Disable Superfetch and Prefetch

    Superfetch and Prefetch, when running, simply tells Windows what it should expect to load next so it’s cached to your RAM. The nice thing about having an SSD of course is that you don’t really need to have things pre-cached into RAM. SSDs have ridiculous fast access times that are many, many, many times faster than traditional platter HDDs. Since, Superfetch and Prefetch is only going to eat up precious memory without giving you much of a benefit in the performance department, might as well disable them since you’ll probably need the extra memory after disabling the pagefile.

    Click start, in the search bar type “regedit” right click your search result and click “Run as Administrator”
    Navigate to this location “HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SessionManager\Memory Management\PrefetchParameters”
    Right click EnableSuperfetch and EnablePrefetcher and modify their values to 0
    Restart your computer

    4. Disable indexing

    When indexing is enabled, Windows is taking what it thinks is the most commonly used files and stores its file locations for quick access. While this isn’t taxing on your SSD, this does tax your processor. With SSDs being fast enough to access all files – commonly used and not at lightning speeds, there’s no reason to have indexing bog down your PC. Turn it off!

    Click Start
    Click ‘Computer’
    Right click your SSD (usually C:)
    Click ‘Properties”
    Under the General tab look to the bottom and untick ‘Allow files on this drive to have contents indexed’


    5. Disable Hibernation

    Similar to disabling system restore, disabling hibernation will allow you to free up tons of space as well. Plus, with your new SSD you can boot into Windows from a complete shutdown and open all your work back up again, just as fast as you can resume from a state of hibernation! That, or just use this other sleep mode called “standby”.

    Click Start, in the search bar type “cmd”
    Right click the search result and click “Run as Administrator”
    Type “powercfg -h off”


    6. Disable Write Caching

    With mechanical hard drives, write caching is quite useful as hard drives frequently can’t keep up with the data that needed to be written on them, so data was stored onto memory first then transferred onto the hard drive. However, since SSDs are capable of extremely fast sequential and 4k writes, this is unnecessary.

    Click Start
    Right click ‘Computer’
    Click ‘Properties’
    Click ‘Device Manger’
    Click ‘Disk Drives’
    Right click your SSD
    Click ‘Properties’
    Click ‘Policies’ tab
    Untick ‘Enable Write Caching for this drive’


    Well, that’s it for now! It’s a pretty good list of optimization for those first time SSD users.

    Hi. Thanks for your long reply. I actually had done most of that. The part that I was missing was ACHI. At first, I couldn't boot at all, it was stuck on loading operating system.

    Here are my new benchmarks, I still think they are kind of low when compared to google searches. Can you take a look?

    Side not for anyone that gets this same issue, I recommend checking for any external drives (it tried to boot my external instead of my SSD), and that my CD drive was needed to be on the IDE sata ports while my SSD was on the ACHI sata ports.
  4. Still looks a little low but definitely not horrible

    What am I doing wrong then? I'm using ACHI for ports 0-3 and IDE ports 4-5. My CD rom is in port 5 and SSD in port 1. I made all the suggestions you made and restarted. Now my write speed is 210 MB/s which seems really slow..

    Am I missing any drivers or anything??

    EDIT: Unchecking write cache makes it WORSE by almost DOUBLE... I checked it back..
  6. You can try to check if your firmware is up to date for your ssd it isn't as bad as your thinking what kind of scores are you seeing have a link?

    Yeah check it back if it's doing that it didn't do that for me but i have different ssd.

    I actually never installed firmware for my SSD. Haha.. let me do that.

    But pictures like this make me worried that I'm lower: http://img233.imageshack.us/img233/8205/samsung840prolsi.png
  9. Yes check that other then that i am out of ideas.

    Oh well I installed samsung magician and updated the firmware. it's still about the same. :/

    Hmmm... sorry bud i don't know why.:(
  12. Just wondering if you tried the automated OS optimization in the Samsung Magician. Although I have a 8350 at 4.7Ghz, your MB and SSD are better than mine ( Asus M5a99x and 830 ) and my 830 is reading at 500 and writes are 280(typical of this model). I also have a Kingston Hyper 3X (data, should be my OS!) and it is 540 and 500! and my old 50GB Vertex 2 is 250/200. When I got the Samsung 830, all I did was run the Magician's OS optimization and let it make the changes, I didn't do anything. All of the steps Bigcyco1 mentioned in his thorough explanation is done for you in the OS optimization. Couldn't hurt to try it, if you haven't already. Not sure if ram speed has any effect, but mine is Crucial Ballistic Tactical 1866 9-9-9-27.
    Question for Bigcyco1: Do memory and CPU speed have any influence on SSD speed? I ask because the flow (speed) of data to the SSD would have to come from the Ram, wouldn't it, or am I not getting something?

    That is using a older version of the benchmark tool so i wouldn't worry about that it's not the same version your using so it's not a good comparison.Also read this http://thessdreview.com/ssd-guides/beginners-guide/the-ssd-manufacturers-bluff/

    That might make sense. I guess it's unknown whether or not my performance is ok? I was told that an SSD during boot time will load before the windows 7 logo finishes. Mine appears to boot as slow as my hdd, for some reason. Or maybe the performance isn't that noticeable?
  15. Just to throw up as comparison

    http://tinypic.com/r/970lft/5

    This is a OCZ Vertex 2 60 GB SSD (SATA 2 incase it isn't obvious enough) with about %85 storage used.

    My 4K measure is slightly better. I don't fully understand those tests but I find it interesting.

    How long does it take to boot? My ssd's are different brand but it takes mine about 15 seconds
