    Very slow SSD 4K read speed

    My WD black 1tb drive used for data would randomly Freeze with a loud hum. So I upgraded to a Crucial ct960 SSD. I noticed the folder that held my downloads was still slow loading medium icons when opening the file first time after restart. So i checked it with CrystalDiskMark. The 4K QD32 read was 1.201.
    My primary drive is a crucial M4 128 SSD so I tested it also and it read 1.87.
    I went back to when I first installed and tested the M4 in August of 2011 and the read speed was 245.5. What happened?
    In 2011 the M4 was installed on a Gigabyte CA-P55A UD3 with a I7 868 2.8GBT and windows 7 32Bit. In June of this year I replaced the Gigabyte P55 with an AsRock Z97 Pro3 and a I7 4790 3.6GBT. A couple weeks ago I updated to 64Bit windows 7 and did a clean install on the M4.
    Which brings me here, to a problem I have not found an answer to. I've been Goggling for days and have found nothing that is the same as my problem or fixes that relate.
    Only thing I can think of is the Motherboard. Help.

    It could be a partition alignment problem.

    That was the first thing I checked and I did have to Align the partitions. Didn't make a lick of difference.

    Thanks for the suggestion.

    Matidor,

    Very Interesting as I get similar results on both my SSD & HDD!

    SSD: SanDisk Extreme Pro 240GB

    HDD: Segate ST1000DM0003 1TB

    Must be something about the 4K algorithm.

    HTH

    Similar results from the Crucial M4 256 in my laptop: (SATA II)

    Note: I used AS SSD (available from Major Geeks) for this test. This program does NOT require an install so it can be run from a USB key and it also reports on the Alignment Status, see the yellow highlight.

    Ditto for my wife's Dell XPS14z w/Crucial M4 128Gb

    FYI: When I first ran AS SSD it showed that the partitions were NOT aligned! I'd recently restored a HDD backup to this SSD assuming that since the PC had Win 7 from the start the partitions would have been aligned on the HDD but not so! I used Partition Mini-Tool Home Editioin 8.1.1 bootable CD to realign all the partitions in one fell swoop...great tool even if it is mini.

    BTW: The installable S/W doesn't create the bootable CD you have to scroll down the download list to the .ISO at the bottom.

    Actually, think your numbers look pretty normal for scandisk and the numbers for the seagate are why we like our SSDs

    Results are similar on my drives too as far as 4K goes.
    I don't think it's your motherboard either, even if you haven't updated your
    BIOS or chipset drivers recently.

    Invest a little time and energy in a well thought out BACKUP regimen and you will have minimal down time, and headache.

    Build your own system; get everything you want and nothing you don't.

    The clean install with windows 7 64Bit was done with all the latest drivers. I have not updated BIOS, Just for fun I'll look again
    to see if there is anything new. But I am now of a mind that would not be the problem. I am perplexed.

    I have the same situation with my Samsung 840s and I have seen tests on places like Tom's Hardware which all have the same type of numbers on 4K reads and writes. It must be systemic to this size read/write pattern.

    Has anyone asked their manufacturer for an explanation?

    I was looking thru Crucial and Samsung's forums but have been busy of late. I've been all over crucial's site Its hard to find how to contact a real person from these sights. A real answer would be nice.

    Obviously someone with a limited CS repair script - at least they have Toll-Free number you can use in the US and Canada - are you going to give them a bell or use the e-mail route ?
