Solved Samsung 840 Pro 256GB Slow Benchmarks!? Tags: SSD Storage Samsung Last response: September 11, 2013 8:48 AM in Storage Share woot903 August 4, 2013 3:51:50 PM I have followed numerous optimization guides on these forums and the web to still be left with an SSD that is under-performing. Here is an image of a benchmark I ran. Not sure if this is a driver issue or what? Bad SSD? I did have stability issues on my first windows install and I had to reinstall. System Specs: Storage: Samsung 840 Pro 256GB (Running in AHCI Mode) MOBO: ASUS M4A89GTD-PRO/USB3 CPU: AMD Phenom II X6 1100T BLACK EDITION FAN: Zalman CNPS9500A-LED GRAPHICS: PNY Performance GeForce GTX275 MEMORY: Patriot Gamer 2 Series 4GB (2x2gb) PGD34G1333ELK (2 of these) CASE: Antec DF-85 Full ATX Tower OS: Windows 7 Ultimate 64bit More about : samsung 840 pro 256gb slow benchmarks Best solution Dereck47 a c 532 G Storage a b Ô Samsung August 4, 2013 7:43:05 PM Your AS-SSD results show msahci - OK, which means that you are using Microsoft's default AHCI drivers. Install AMD's latest Chipset/AHCI drivers and see if that gets you better performance. http://support.amd.com/us/gpudownload/windows/Pages/rai... Also, although your motherboard has 6 SATA 3 (6Gb/s) ports, connect your SSD to the 1st port (SATA1) and see if that makes any difference.

It includes AHCI drivers. m 0 l woot903 August 5, 2013 4:32:15 PM Moved the SSD to SATA 1 (first sata port) noticed a small boost in some areas of performance. I will install the drivers and update my other results here. m 0 l woot903 August 5, 2013 8:37:20 PM Installed AMD SATA Drivers for AHCI and saw a boost across all benchmarks. Sadly the Random Read is still very under-performing and all other benchmarks could still use a significant boost. What else can I try? m 0 l Dereck47 a c 532 G Storage a b Ô Samsung August 5, 2013 8:59:29 PM Sorry, don't know what else to suggest. Hopefully other Forum members will have suggestions. You went from a total score of 503 to a total score of 857. That is an approximately 70% increase. Other AS-SSD benchmarks for your model show 4K Random Read results in the 30's, which is in line with your results. What results were you expecting? Here's a link where you can look at benchmarks from other review sites: http://www.johnnylucky.org/data-storage/ssd-database.ht... m 0 l woot903 August 5, 2013 9:33:14 PM http://www.overclock.net/t/1379302/are-my-4k-read-write... Many others report final scores of over 1000 with AS SSD. With lower acc times, higher sequential and 4k-63thrd speeds. m 0 l Dereck47 a c 532 G Storage a b Ô Samsung August 5, 2013 10:23:00 PM Your motherboard uses the AMD 890GX / SB850 chipset. You probably need the current generation chipset (990FX / SB950) to get maximum performance from current generation SSDs. m 0 l beetchu_ez August 8, 2013 7:59:18 AM woot903 said:Which driver set do install?

Not sure what the issue is there. m 0 l woot903 August 8, 2013 1:55:56 PM Quote:You probably need the current generation chipset (990FX / SB950) to get maximum performance from current generation SSDs.
