    If you want to know the performance of your hdd installed in your Vu+ box you can use this procedure and post here the results.

    Warning: This test need 2 Giga free on your hdd. Be sure that your hdd is mounted and to cd into your hdd folder or you will fill your flash.

    1) telnet to your box
    2) be sure you know where your hdd is mounted (my hhd is mounted in /media/hdd)
    3) cd to your hdd (using the path of your hdd):
    Code:
    cd /media/hdd
    4) run the command
    Code:
    dd if=/dev/zero of=./output.img bs=8k count=256k
    5) run the command
    Code:
    rm ./output.img
    Post here the result with this form:

    dear users.
    from these tests it seems that the disks formatted in ext4 have really better performances in Vu+ box.
    As you can see the first disk of this list was able to tranfer 2 Giga data in about 13.9 seconds with a transfer rate of 146.9MB/s.
    This disk is partizioned with the optimal alignment and formatted in ext4.

    All the other disks formatted in standard e2 ext3 of this list are too much slower with tranfer rate about 44/55 Mbs.
    The only other disk near a good value is the internal WDC of cyborgpunte that is formatted in ext4 that report about 90MB/s of tranfer rate.

    For this reason the hdd initialise function in the next Bh 2.0.5 have been modifyed.
    The next Black Hole 2.0.5 will format your hdd with optimal alignment and ext4 filesystem.

    So for all users that want to improve their INTERNAL hdd performance i suggest to start to backup their data and to format again theyr hdd in the next bh 2.0.5.

    P.s. @all users that are planning to buy a new hdd: Remember that the next Bh 2.0.5 will support internal large hdd up than 2 TB.

    Someone asked me howto discover what kind of filesystem is using your hdd.
    A simply way is to telnet to your box and digit command: mount

    Here is an example output showing:
    usb pen: ext3
    hdd: ext4

    Code:
    /dev/sda1 on /media/usb type ext3 (rw,relatime,errors=continue,user_xattr,barrier=1,data=ordered)
    /dev/sdb1 on /media/hdd type ext4 (rw,relatime,barrier=1,data=ordered)

    Uhmm there is another variable that could make the difference.
    Solo2 and Duo2 could be more faster because are SataIII

    Looking at the results it seems that all the better tranfer rates are in Solo2 and Duo2 box.
    We have to wait for comparaison on the same box with the same hdd to know if there is a significative difference between ext3 and ext4.

    Thank you for the test
    and don't worry, ext4 is better anyway.

    P.s. i suggest to repeat the test two times when you will be ready.

    Wierd, but when testing fileaccess R/w (samba) to my 2 disks
    from my windoze XP/wifi, the external USBdisk is the fastest one approx 1/4 faster.

    Just thought I'd try this a few times
    Code:
    root@vusolo2:/media/hdd# dd if=/dev/zero of=./output.img bs=8k count=256k
    262144+0 records in
    262144+0 records out

    2147483648 bytes (2.0GB) copied, 23.592363 seconds, 86.8MB/s
    
    Got varied results from 73.8MB/s to 86.8MB/s.... Don't know if that info is useful but their you go.

    But using Mount command found out
    Code:
    /dev/sda1 on /media/hdd type ext3 (rw,relatime,errors=continue,user_xattr,barrier=1,data=ordered)
    
    So drive actually formatted as ext3 (I'd assumed it was ext4 as used solo2 to initialize) and getting good speeds in Solo2?
