The compatibilitylist lists up several 1TB disks - but what happens if you put in Seagate and/or Western Digital 1.5TB disks?

Will it work - and if so, with 1.5TB or only with 1TB?

Per this link:

which I gather you located :-)

Are the tested drives we feel comfortable recommending since Q&A tested with them. 

So what happens if you put something else in there cant be answered until someone tries...

Then of course, it becomes an issue of support if it doesnt work (may be hard to get support)

I got an email from QA who is running the certification tests for bigger drives.  If everything is working, the  AVL list will be updated in a few weeks time.

Indeed, but it doesn't work well. We had several units with 4 times 2Tb approved disk, and it's a disaster.

With 4 times 1Tb, it's better but not really stable neither.

Don't trust the NSS4000 unit, it's not a professional device at all, and your data are definetely not secure on it.

RAID5 is not working properly, firmware is more a beta than a real firmware, and cisco support is useless on this kind of device.

In case of problems their only solution is always "delete the array, recreate one and restore from backup".

That's the 3rd time that we lost our 6Tb data due to problems with this device. We'll replace it with another brand with correct support and just throw this one away. It's useless.
