*twitch* In almost every instance of someone setting up a *10, a *5 would be better. Or a RAID-6 for more than, say, 8 drives in the array.

It depends. Raid 10 is less likely to have drop out issues with cheap drives (ones that don't have TLER). Personally, I would just go two 1's if its just going to be used for storage. I don't know if this is a problem with whatever RAID implimentation Kitamesume may be planning on, but I wouldn't try it with my ICH10r chipset, nor with my old (and shitty) High Point (grabs the piece of shit off his desk) 2310 card. Haven't tried it with anything else, but if you don't have drop out problems 5>10 so long as you don't mind super super slow write rates. If you have a card with on-board RAM buffer chances are there will be drop out issues.
[edit] The on-board RAM buffer helps with the write rate A LOT, but those are on high end cards. I wanted to buy a Adaptec 6405, but with my Samsung drives, I would have had drop outs like crazy. In addition to the card, and the battery back up (don't use write-back without a back up of some sort), I would have had to purchase high end drives and tied up 8 lanes of my PCI bus.

lol, anything that'll cost me another 200$ would push the project another year or so XD thats how bad my funds are right now =(
well its either clustered drives with no raid at all and raid it later on or pure all out USB/eSATA-HDDs funfest(this is where the laptop HDDs idea came from, hah hah hah...).
nstgc:
Why not just use RAID 1 for storage? If that's all its form it should be fine, and as far as I know all major desktop and server operating systems offer OS implemented RAID 1.
kitamesume:
^ eh... i already said it "and raid it later on", because i'll be buying HDDs on piece by piece basis and it'll take months for each to be bought so... you know =D i can't raid something that doesn't have a pair. to begin with, my plan was stock piling external harddrives XD well the 2.5inch ones so there wouldn't be a hassle of an external powersupply, hence the question about laptop HDDs. but since someone replied that they don't have much difference in failure rate then maybe internal drives would be better because they're much more cheaper =P

I don't use RAID as a substitute for backup. For backup, I simply copy the files off to another SATA drive that is slid into the hard drive bay slot. When done, open the bay door and the drive is ejected out and I put the backup drive back on the shelf in its OEM antistatic wrapping. It's easy, fast, and economical to backup my large files that way. For other small frequently updated files, I use an external hard drive via USB.
Hotswap RAID is to reduce downtime for business use. In my mind, it's not appropriate for home use as backup.
