Not sure if this is the Android application or the Linux Controller, but I came across a fun one the other day. I think somebody skipped the 'T' in the KMGTP sequence.

I am replacing my 10-year old Synology NAS with a new one, and I've transferred quite a lot of data from the old one (just under 4TB), but the Omada Android client is showing the new NAS as having used 3.6PB (yes, PETA-bytes).  For those that are about to Google it, each PB is 1,000,000 GB or 1,000 TB.  

Here's where the math gets fun.  I only powered up my shiny new NAS for the first time almost 15 days ago, and it is connected to my Omada switch via a GbE (1Gbps port).

15 days X

24 hours X

3,600 secs/hour X

1,000,000,000 bps

Divide that by 8 to get bytes

Divide that by 1,048,576 to get MB

Divide that by 1,048,576 to get TB

You get: 147.3TB

it's not even physically possible for my NAS to have done the following, even if the port was PINNED 24/7 at 1Gbps for two weeks (it would need almost a year!):

and here's the client (Synology NAS) history breakdown from the app.

As you can see it manages about ~5TB/day between the two boxes.
