    I have a Thecus 5200 BR pro.
    I have 5 drives in it (4x Seagate 1.5TB and 1x samsung 2.0TB) in raid 5

    Max continuous writing throughput I've observed while copying over gigabit is between 12-17MB/s.
    Max continuous read throughput is about 30MB/s.

    For my purposes this is ample.

    The way i read that was consumer grade networks will reach gigabit speeds but its the NAS that holds you back.

    For what its worth i can get 80mb/s on a Dlink DGS1008D switch from laptop (7200rpm) to Freenas system with no raid (also 7200rpm drives).

    NIC's are all on board/builtin.

    tobes, save yourself hassle, money, time and everything.

    1. grab a 2tb drive from pc shop (don't pay more than $150)
    2. whack it in a PC
    3. share it on the network
    4. relax with beer in hand

    I got the n5200B from these forums. Currently have 3 x 1TB WD Green drives in JBOD with an average write speed of 40MB/s over gigabit. :confused:

    Jbod doesn't slow things down at all - Raid 5 needs to write parity bits and requires parity calculations.

    That's why writing is so slow.

    I never expected it to drop so low though

    Yep, read up on how raid5 actually works and you'll see there is a lot more to it than just writing extra parity.

    yep! these lower end NAS have typically slow CPU with small amounts of RAM.

    It's not the disks or the network slowing their capacity..

    When you start looking at the $800+ to $1000 mark then you start talking boxes capable of writing to RAID5 (or the like) at closer to 50-70MB/sec

    This nas has a 1.6ghz celeron cpu with 512mb of ram.

    So yeah it's not a cheap nas, but there's a lot it needs to do.

    Is it a simple matter of the guys getting confused between gigabit/second, and gigabyte/second?

    Gb=Gigabit
    GB=Gigabyte....

    Or, am I missing something here :)

    I can only assume he now understands how Ethernet works.

    Never expected a reply btw...but would be nice to have closure after such a negative post :Pirate:
