If you're feeling frisky, you could clone my github repo, make the necessary changes, and send me a pull request and I'd be glad to roll it in. Or, you could send me a patch file. Otherwise, I'm not likely to get around to it any time soon. Thanks, though! I could probably do that.

I note that the Adruino LCD library has an option to NOT use the "RW" line. You wire RW to GND. You can get away with this if you have only a single LCD on the data lines. It saves an I/O line (always scarce). Have you considered add this as an option? Thanks... Nice library. I note that the Adruino LCD library has an option to NOT use the “RW” line.

]]> Comment on Why RAID-Z isn’t appropriate for me (or for almost any home user) by Erik http://www.ralree.com/2011/08/21/why-raid-z-isnt-appropriate-for-me-or-for-almost-any-home-user/comment-page-1/#comment-4523 Erik Sun, 28 Aug 2011 20:00:34 +0000 http://www.ralree.com/?p=23178#comment-4523 Jerry - thanks for pointing that out. I should have discussed that option in the post. I had seen people mention it, and decided against it since it's extremely inconvenient. It does depend massively on how fast you fill the space, as you say. If you're on a 3-year plan, it's completely viable, as you seem to be. However, I built my 4TB RAID in November, and now less than a year later I was getting low on space. So, for me, the ability to just slap another drive in there, run 4 commands, and have 2TB more space is extremely nice. Migrating from hardware RAID is a really good idea, unless you have a $300+ RAID card (mainly because it probably has built-in memory). Modern software RAID can get you close to the same performance for most activities - you're much more limited by the filesystem. Currently, I'm seeing 250MB/s+ for reads and writes using mdadm, and that's on 5 5400RPM drives - it's pretty amazing. I'm not using the disks for small files or random access - just large sequential reads - so XFS is working out really well. Deleting files is really slow, but I can live with that. Cheers!

Whether you can live with this alternative depends on how fast you consume the original data space. I started with 5 500 GB drives in a hardware raid three years ago and now am looking to migrate to something larger. I'm also looking to move away from hardware raid so I can move the drives to a new platform without worry of cost/time to replace the hardware raid card. I have not started the rebuild yet, but ZFS does appear to be the right solution for me. I think you should take a look at this blog post:
