When The Spark Fades…

My decision to buy my first “proper” NAS box, back in 2012, was  really driven by the mixed experiences I’d had with an Apple Time Capsule. In principle the ATC is a fantastic idea; in practice Apple designed it down to a price, chose poor quality components and mine – like so many of the first generation units – burnt out it’s PSU after about 2 years [just outside warranty].

I replaced that with a QNAP TS-459 [which has been brilliant], and did really well until the first set of HDDs I’d purchased [Western Digital Greens, 3Tb each] began to fail. A hurried purchase of a larger/newer/better TS-670 followed, with this crammed out with no less than six Western Digital Reds, 6Tb each, configured in to RAID 6. The older 459, meanwhile, took a brace of 4 x 6Tb Reds, configured to RAID 5, and now exists primarily to be a “local” backup to the 670. [I have the machines configured to run a 7-generation backup at 2am every morning – works brilliantly].


Not even this can cope with a power outage. Enter one of these:-

It’s a “UPS” – an “Uninterruptible Power Supply”, basically a battery, a mains conditioner and an inverter, all in a neat little box that measures about 25cm x 25cm x 10cm and has the ability to power up to 4 devices for a reasonable period of time in the event of a power outage…  From experience, it’s uncommon to get a power failure that lasts longer than a couple of minutes [usually it’s just the electricity company doing some sneaky maintenance in the middle of the night]. In other words, this should be more than enough to keep both NAS boxes nice and safe, even through a power cut.

Just to be on the safe side, this UPS also has a cable which I’ve connected to my NAS. If the power does fail, the UPS will alert the NAS, which have the ability to shut themselves down smoothly, before the batteries fail.

Not bad for £60 + cables; let’s hope that now I’ve got this, I won’t actually need it…
