I was quite impressed when I received an e-mail advising me that Western Digital are now offering a new drive called the My Book Thunderbolt Duo with an Intel Thunderbolt interface port with a supposed transfer rate of 10Gb/s or 10 Gigabits per second.
But all is not what it seems.
Unfortunate my initial enthusiasm was somewhat diminished by reading the fine print in the speed graphic.
The actual performance of the device is given in MB/s or Megabytes per second, not Gigabits, so some arithmetic has to be done. Eight bits to a byte leaves us with a maximum speed of 2000 Megabytes/s or 2Gb/s, way below the indicated throughput of either Firewire or Thunderbolt port.
In fairness to Western Digital, the fine print is there, you just have to work at finding the truth.
The 10Gb/s throughput of the Thunderbolt interface is actually supposed to be a combination of up to two HD video channels, and multiple data devices, on a single cable, not a single device. The transfer rates are based on the manufacturers specification, not the realities of the device in question.
In short read the fine print.
I have been stung by transfer speed claims before. This is not the first time a manufacturer has erred on the side of hype, and will not be the last.
Have you been caught by claims that where not supported by reality?
Why not share with us, I would love to know how you feel.
I have used a D-Link DI-624S storage router for a couple of years now. I received a lot of criticism, much of it well founded. The ability to share printers and USB drives was a good idea, but it lost something in the implementation. Recently it died completely overnight. In the evening, the internet was offline, but the internal network was functioning. In the morning, I rebooted it, and it just did not come back. The same day I replaced it with the well reviewed Linksys (Cisco) WRT160N Wireless Router.
The WRT160N is a thing of beauty, looking more like a jet or flying saucer than a wireless router. But it also performs most impressively. It has outstanding wireless coverage. I walked around with my Asus Eee connected to the wireless network. I could get two doors down the street, or out into the back yard and to the back fence with full wireless network speed. And with 802.11n it is faster than any WiFi card I have at present.
It seems there is a problem though. It began to drop out, with DNS errors (site not found, etc) and I had to do some research. It appears the the router has a security vulnerability, and in an attempt to fix it, Linksys upgraded the firmware and introduced a bug. here I go again. I seem to buy the lame ducks!
The vulnerability is reported by Secunia here
Then solution was to install the older version of firmware 1.2.02_008. A web page showing how to do this has been posted here . Once the firmware was downgraded, and the DNS settings changes, the router began to work fine.
I will watch Linksys for a firmware upgrade, and hope they post one soon. In future I will spend more time reading the newsgroups associated with these products. It was a quick decision because I needed to get back on the air.
I am very pleased with the Wireless performance of the WRT160N, but not with the lack of comment or action by Linksys. I know it takes time to produce and test firmware, but there should at least be some comment on the problem.
How about it Linksys, are you taking any responsibility for this? The issue has been documented and discussed endlessly on your OWN FORUMS and still, four months later this defective product is still in the stores.
