Power down or freeze only on weekends???

For the last 3 weeks in a row and a few times at random before that (always on the weekend though) the ready nas 1500 (rackmount 1u) we have has shutdown or frozen. The DCT led (solid green) and the network led (blinking green) directly to the right of the DCT light remains lit but the nas itself is completely offline and not accessible nor is the admin http page. I have to turn it off and then back on. My first thought is this may be power supply related, it seems strange that it runs fine under load all week and then goes down on the weekend when no one is around.

The nas is running egnyte as an addon, other than that it is bone stock with a 3TB raid array (4*1TB).

The last sync that egnyte reports when these freezes or shutoffs occur has always been on a Saturday in the morning which means to me the box is going down Saturday morning every time. There was an update to egnyte that happened about a month ago, maybe their new addon is the problem?

Any thoughts or possibly related stories?

Thanks

    On the load-cycle count, I have some green drives in service with ~1.5M load cycle counts that are still performing well. My NV+ has green drives with over 500K LCC counts, and they are working fine also. So in my experience these drives generally do out-last the 300K spec by a large margin. However, there are better choices for NAS, so I don't recommend them for new installations. I've chosen to retire them from my primary NAS (a pro-6).

    I don't use enterprise drives myself, so I can't really recommend any. I had a run of seagate failures years ago, and have stuck with WDC for some years now with good results.

    Though the WD Red drives are much better than the green drives for NAS, and are somewhere between consumer and enterprise grade. There is a 1 TB model - the WD10EFRX. I've used WDC Reds in my pro-6, my duo v1 and my RN102 with good results. They might not be on the compatibility list, but if you are out of warranty that probably doesn't matter much.

    There's a new WD Red Pro line which appears to meet enterprise specs and warranty (for instance the WD2001FFSX). 2 TB is the smallest size though. There's also the RE line which is their true enterprise line, and still has a 1 TB model. I haven't used either though.
  • I don't see the ReadyNas1500 in the list to select hard drives. Link to the NAS: http://support.netgear.com/product/RNRX400E%2B$28ReadyNAS%2B1500$29
  • Is the air conditioning set to a different setting on the weekends? Or maybe doors closed that are open on work days, changing air circulation? If it's getting warmer, that could be the trigger.
