But when your computer does have normal RAM which is faulty, it will corrupt the file and copy it to the NAS’s ECC RAM, which will write the corrupted file to disk, as it can not detect the corruption. First only a few, “pro” graded systems have dcc ram. All files would be lost! See another explanation in the FreeNAS Forum.Īs a side note: An external storage or NAS, like a synology, etc, will not be sufficient. When using ZFS this will be even more disastrous: The checksum for each file will be calculated wrong, and in the effort to repair the wrongly presumed file with the parity copy it will be written corrupted. Every time a file is read to ram and written to disk (when editing or copying) the file will be corrupted – the second and third bit will be changed to ‘1’ no matter what it really is (simplified example).

To illustrate why this is important imagine the second and third bits in your RAM are faulty, meaning they stick to the state ‘1’ permanently. Why? It is not so much the correction of a faulty bit which matters, but to avoid any faulty bit to be undetected, as a ECC supporting machine (RAM, CPU and Motherboard needs to support it) halts on RAM errors. First one needs a machine which supports ECC RAM. It is impossible to design an LED using current tech that does not do this because any angle (besides 90') goes through more phosphorous/etc coating depth to achieve white light from the blue LED die.I recently set up a file storage with the purpose of being super safe.ġ. In order to get a less perfect spread to produce more usable light, you also produce more less usable light that is going off in the wrong direction that decreases the vision of everyone else. There is also the intensity, beam spread of the LED vs incan elements which have perfect spread. It is not enough that they are in the same location as the original bulb filament. There is ALWAYS glare from headlights, just a matter of how much and where it's aimed. There is no way to increase light output, particularly in a colder hue, without increasing glare. 'To my (subjective) eye, light output seems to have increased considerably. 'I have noticed no glare while looking at the lights at night from a hundred feet away.' If you state they're legal I'd accept that, but your following two statements are impossible contradictions:

The Canadian Tire site lists this Zevo 9006 as approved for my truck and there is no maintenance required for these bulbs, so I don't see any basis to deny warranty.

I did not see any fine print re the 5 year warranty. Not bad at all if these last the rest of the life of this truck as I am expecting it to. Https:/ / en/ pdp/ 9006-sylvania-zevo-led-headlight-bulbs-2-pk-0202691p.html#srpĬanadian Tire had a promo, around Christmas time, where they mailed you a $50 coupon for a $200 online purchase, so I effectively paid $149.99 for a pair.

Makes me long for the good old days when a shop only had to stock round and rectangular sealed beams, 11 for turn, parking and backup, 194 for instrument panel and 211-2 for dome lights, to service any car. The Zevo lineup at Canadian tire seems to have expanded considerably since I last checked I bought them from Canadian Tire, not from some questionable e-bay source.ĭo they have other bulb configurations? I will have to go have a look at these. They are available at Canadian auto parts stores.
