Hi, thank you for the review, I found it very interesting and useful! In the review you say that the nas supports system sleep, but does it work like a "Suspend to RAM" mode or is it just a slow hibernation to disk? Does it take so long to wake up? Also, there is no info about the performance with encrypted folders. I hope that the built-in cryptographic engine will be used by the system...

It's a pretty much a suspend to ram with HDDs in sleep - it, however, is pretty fast to wake up, seconds only and certainly not the windows hibernation experience. However, that is dependant on the storage you use. A HDD based RAID array is slower to wake up opposed to using SSDs in there, overall it's plenty fast in my experience. In my office I use an ASUSTOR with HDDs, that's roughly ~5 seconds to wake up. Not bad at all. If you want to encrypt your storage, I dunno. I have not tested it, but expect a perf hit on this specific processor. And overall, ASUSTORs I consider top of the range NAS units at an affordable price level.

I do not have the AS4004T unit installed anymore but it should be universal with all units using the same ADM (unless they removed the feature somehow related to the CPU). Here's what my current NAS shows with the latest ADM, did you check under hardware > energy control and power?
