Re: Raspberry Pi Powered Forum

Yup I found that caching works fine as long as it is properly configured. Host all your images off-site (such as picasa) and compress the css and gzip the entire lot and its pretty slick. You will find that Wordpress is also amazingly fast with static page caching. Basically you don't want to call P...

Re: Can Rpi Runs 24/7 as a server for my point of sale

My PI has been running 24/7 for over a year now. Its also still on the original SD Card (after eating a backup due to a number of power outtages a month or so back). Pretty good going tbh. Things that will work: static pages. Things that will not work: MYSQL/PHP5, using a $5 cell phone charger (lol)...

Re: My webserver, running 24/7

My server has been up 14 months @ http://grognard.sytes.net/ I had some early woes, but when I switched to using Sandisk SDHC 4gb cards I stopped experiencing issues with them becoming corrupt. I also use a proper regulated switching power supply, which was so worth the £13 or so it cost. I had been...

Re: ext3/4 and SD-card wear leveling

I've been using F2FS for a while now and it's definitely faster. Whether my SD cards last longer won't be known for a while yet, but it's close to two months now without any sign of any problems. That statement pretty much guaranteed that my SD card would die, and it has. All my previous cards have...

Re: ext3/4 and SD-card wear leveling

A small question: due the fact that sd has wear problem why not use it only for root and use an external usb hdd drive for the os? For sure it will be slower but for not intensive usage could be nice. Suggestions? Cost. Powered hub (a proper one) £20. A USB HDD and caddy (£60). Cables £2. Electrici...

Re: Read/Write cycles of a SD card

The main problem is unclean dismounts/shutdowns corrupting the fs and maybe causing damage to the cards themselves too. I've been through 3 cards since I got my rev 1 pi way back when. All caused by catastrophic root fs corruption, all caused by power outtages, lock ups leading to power outages etc....

If they make a version 3, or model C, or whatever, the only thing I would like to see would be more r...

Which SD card was it that failed? manufacturer, model and size? Well it didn't fail, so much as fall prey to PiAIDS ie. inevitable corruption due to power cycling. Outages, lock ups etc. I run it pretty 'mental' to cope - so no logging, no swap, chunks of mysql in ram, long periods between write ou...

Hey thats not a bad run eh. I wonder if some manufacturers claims about writes/lifespan are really being tested in ways (and short timescales) they may not have envisaged just a few short years ago? I think that is true; these cards were probably only intended to write large files not be subjected ...

I'll be naughty and answer my own question: http://forums.anandtech.com/archive/index.php/t-2084771.html In short, limit writes and its a viable alternative to sdcards. Probably less prone to power cycling causing the fs to eat itself too.. But not ideal due to lack of any real wear levelling. The R...
