DSM 5.1 on Synology DS409slim

• • 3 Comments

Since I turned my DS409slim into a DS411j, I have access to DSM updates. So tonight, I upgraded from DSM 5.0-4528 Update 1 to 5.1-5004 using the update wizard. So far, everything went OK. On first reboot, I was recommended to keep my DSM up-to-date using automatic upgrade. As I don’t want my NAS to reboot while I’m working on it, I choose to “Download DSM updates but let me choose whether to install them”.

That’s all about it 🙂

    hi,
    Thank you verry much for your report, updating your ds to dsm5.x
    I’m thinking of trying it, too. But I have two questions:
    Is there any loss of performance with the new dsm?
    Is there a way to turn the dsm back to thedsm 4.2?

    Thanks

    Matthias

      Hi,

      The Web interface seem to be a bit slower. Probably because of the low RAM capacity. But the other services work well.
      I’ve never check for roll-back possibilities 🙂

    After a couple of weeks, DSM v5 is definitely not for DS409slim. Looking at the logs, there is not enough RAM to run the thing with decent performance. I’ll check and post about downgrading soon to DSM v4.
