Not happy with the transfer rates I get with my Thecus N4100Pro, I decided to look into what could possibly be the problem. It turns out that with overheads, the maximum transfer rate I’ll get from it is around 8-10mb/sec – if I’m lucky. Since I deal with large files on a regular basis, this has already gotten to the point where it’s beyond doing my head in, so I decided to upgrade my router (which doubles as a switch for 3 devices) to a gigabit model. That way I could expect transfer rates more along the lines of 70mb/sec, apparently*.

* I say apparently because while the maths behind that increase ratio does make sense, the maths also predicts transfer rates of more like 12.5mb/sec on a 100mbit line – so to be getting 8-10mb must mean there’s quite an overhead involved…

Anyway, after looking around I settled on a D-Link Xtreme N Gigabit DIR-655 and promptly searched for some prices on Google Products.

PIXmania was the first name that I’d heard of before (and bought from previously), so although they weren’t quite the cheapest I decided to go with them – the power of brand recognition working a treat. PIXmania had it for £79.90 including VAT, so I went to the site, added it to my basket and went to checkout. Just then Firefox crashed, so when it loaded back up I manually navigated to PIXmania’s site and searched for the router. To my amazement the router was now £96.98 including VAT! That’s a 21% increase in price, with the only difference being that on the first occasion I was referred from Google Products and on the second there was no referral.

I went back to Google Products and did the search again from there. Sure enough, the router came up again for £79.90, so this time I went in and bought the router from there. I checked out, paid via PayPal and now have an email receipt for £79.90.

It would seem that PIXmania is slashing prices on price comparison websites to make themselves more competitive, yet hiking them up again to non-referrals who are unlikely to have compared their prices before making a purchase. The moral of the story here is to always use price comparison websites whenever you’re making a purchase online!
