    SATA III is giga**bit**, so the max speed is actually 600MB/s.\n
    \n
    What filesystem? For example, on my ZFS pool I had to let ZFS use a good chunk of my RAM for it to be able to cache things enough that rsync would max out the throughput.\n
    \n
    Rsync doesn’t do the files in parallel so at such speeds, the process of open files, read chunks, write chunks, close files, repeat can add up. So you want the kernel to buffer as much of it as possible.\n
    \n
    If you look at the disk graphs of both disks, you probably see a read spike, followed by a write spike on the target, instead of a smooth maxed out curve. Then the solution is increasing buffers and caching. Depending on the distro there’s a sysctl that may be on by default that limits the size of caches to prevent the “I wrote a 4GB file to my USB stick and now there’s 4GB of RAM used for it and it takes hours after finishing the transfer before it’s flushed to the stick”.

    From Wikipedia, the free encyclopedia\n
    \n
    Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
    \n
    Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
    \n
    ### Rules\n
    \n
    - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
    - No misinformation\n
