    Ridiculously slow transfer speeds


    I have been having an issue with file transfers starting at 300MB/s then tapering down to around 20-30MB/s (as low as 6MB/s on the Firecuda) This is based on a 26.4 GB folder of Karaoke files (CDG & MP3 only). This seems ridiculously slow to me.
    I am not sure how to tell if it's the Ryzen chip, motherboard, or controller etc. My computer guy moved away, so I am hoping someone here can offer some advice on how to proceed.

    This happens with all three discs on my system.

    I only consider myself a low to mid level tech type, so please keep that in mind.

    System Specs

    MSI B350 Tomahawk
    Ryzen 5 2400G OC'd @ 4GHz
    Patriot Viper Elite 2800 2X8GB OC'd @ 3200
    Crucial CTX500 SSD in SATA3_1
    Samsung 961 Polaris 128GB M2 in M2_1
    Firecuda 2TB 2.5" in SATA3_2
    Gigabyte GTX 750TIOC 1GB @ 1.1GHz in 16x
    Windows 10 Pro 64 bit

    I have set the optimize drive service to automatic in windows, and that help bring the low speed average up on the SSD's (No change on low end for the Firecuda) but I would still expect at least around 200MB/s out the SSD's on a SATA lane. This is not the case.

    I would like to clarify that the base system (board, ram, polaris (for OS only)) with the OC was tested by my computer guy, when built, and found to be rock solid over a 48 hour test, and the Radeon graphics are disabled in the BIOS. This system is babied being used in a cool room with air filtration (I know a little excessive, but just as much for me as the system. LOL)

    RAM Usage is at 20-27% (CPUID HWMonitor)
    CPU Usage max was 73%max on CPU#7
    the rest were anywhere from 3 or 4% to
    around 45-60% (CPUID HWMonitor)

    I have tried to to provide as much info as I can think of, but again, just learning. So, if there is any further info needed, I will do my best to get it posted asap (I have an insanely hectic schedule, so might be up to a day or two to reply). Please be patient. I WILL answer back.

    Again thank you in advance.

    Hi there

    @Lequarius

    1) try and remove any sort of optimising off an SSD drive - these don't need it - especially with that CPU you have
    2) disable all A/V (Anti Virus software) apart from WD (Windows defender).

    The other thing is that HDD transfer is highly dependent on the RPM speed and cache size of the HDD -- don't worry about the SSD - it has no moving parts and speed is light years faster than typical classical HDD's anyway.

    If you've got slow RPM disks with a small cache size you'll get hideously slow transfer even if you had the fastest cray supercomputer on the planet with the fastest I/O bus around.

    HDD's should be at least 7200 RPM or even better at 10,000 RPM with the largest possible cache size. A slow 5400 RPM HDD (probably what your 2TB disk is with a tiny cache) -- will make a system run as slow as molasses for data transfer !!!!

    Without knowing more about the physical engineering specs of that machine I can't suggest anything else -- but you should be getting normally at least 300 - 500 Mb/s transfer speeds on average. I assume its direct file transfer and not over a LAN or wifi.

    Cheers

    Seems the right sort of speed to me considering the hardware components involved and the file sizes.
    The lowest speed components involved in the transfers in the system will prevail.

    Thanks guys. I have all SSD's in my system except the Firecuda which is hybrid SSD/HDD.

    This is my whole point of my question. I would think the speeds should be 300-500 like you said, but I am getting nowhere near that kind of transfer speed.

    I am trying to figure out why/where is the bottleneck.

    Suggest you find out what's using your CPU time if your PC was nominally idle then. Should be <3% -say- when idle (which includes no updates/internet usage...)

    There are threads on this site on low transfer rate which you are welcome to research.

    Transfer speeds are variable, depending on the size of the file, CRC, hardware, LAN, LAN to WAN speeds, etc. Dslreports.com has tools to check line conditions, etc. Speed tests, ping tests and bandwidth tools | DSLReports, ISP Information

    The usage was during file transfer. Have determined the slow transfer speed on the Seagate Firecuda is due to a bad HyHD. In the process of getting an RMA. Not too happy with Seagate lately. Seems like nothing but junk.


    Other drives are all SATA lanes with SSD's capable of 550/530 read/writes according yo manufacturer. Am going to run some Crystalmark tests this weekend on them. I will posts the results.

    Thanks again for the input folks.
