StreamNAS Power Consumption

1229

Setting up the Stream as STREAMNAS!

First of all, I should probably list the (both self- and externally-imposed) criteria for my ‘NAS’:

  1. Always-on, and thus low-power.

  2. Non-fixed: needs to be person-portable.

  3. Cheap! I was determined to see what I could do with what I have rather than simply 'buy my way out' of the problem.

  4. Beginner-level... I'm not quite an experimenter yet, but I have ambitions.

Basically, I wanted an always-on, networked, backup system; it’s just a glorified (but somehow unholy) NAS. It consists of an old fanless netbook that was gathering dust and three old hard-drives (in various external cases).

My use-case is a central repository for the home which can be written-to and read-from with any device on the network, including mobiles, as a basic back-up. It means I can access data, & especially media, where I would previously need to copy over piles of media whenever I set up a new PC.

Every couple of weeks, I plug in an external HDD and copy over new data for off-site storage.

Using between 26W and 32W of power, which is more than BushNAS, but probably the lowest I'll manage with what I have. (Again, I'm trying to avoid buying my way out of problems.)


24.08pkWh–¹/1000/100*24h*365.25*28W = about £59 per year.

(£/Wh x hours in a year x ~average power draw)


Shares are (so far) appearing ok on another PC.


Seems to go down to around 15W when screen is closed: even better!
