Write Speed ReadyNAS 102

Hello

I have had a search through the forum and online and feel I have a speed issue but not sure what to do next. I thought it might be my router so I have connected my MacBook directly to the ReadyNAS and I am getting 16.8608640 Mbps (Megabits) write and 622.8530800 Mbps (Megabits) read. The read seems fine to me and more than fast enough but the write seems a little low (It is causing problems when trying to use the NAS)

Please could you help me try and troubleshoot this as I am now a bit lost as to what I should try next.

Many Thanks

Ashley

    How are you measuring the speed?

    Have you checked the SMART stats on the two disks?

    Write speed should be about 50 MB/s (~400 mbits) btw.
  • I am using Lan Speed Test to measure the speed.

    Please advise how I check the SMART stats?

    Thanks.
  • Thanks. The logs look okay to me:

    Does anything here seem like a cause for concern?
  • Hello the drives are about half full. this has been the speed since the beginning. All testing has been done in a Mac OS X environment as my Windows machine is rather old and I've had a pig of a time trying to get it to work in Windows.

    Any other ideas or do you think it's a call to tech support?

    thanks for removing the serial numbers by the way :)

    Contacting support is reasonable.

    I'd also try manually timing the transfer of a large file to see how that number compares with lan speedtest.

    Also, try testing both smb and afp.
