Raid 5 or Raid 10?

[Banzai_Joe]

So,
new HP microserver has 4 bays, my dilemma is:
4 x 1tb WD reds in raid 5 = 3072Gb of usable storage
4 x 1tb WD reds in raid 10 = 2048Gb of usable storage.

2046Gb isn't enough really, so i may have to pay more for the 2Tb reds to give 4096Gb of storage in raid 10.

What would you guys do?

a) if you only had 4 x 1tb drives, raid 5 for more storage or raid 10 for less storage but better performance etc?

Thanks for any input.

Well.....ideally i want to load the host hyper-v 2012 onto a 512gb ssd,
then have 3 x 2tb wd reds in raid 5 which would still give me 4Tb usable storage.
I will hyper-v WHS2011, and whatever else i fancy as testbed or otherwise.

I'm not new to raid, i'd prefer it on a server for sure.
The new microserver has hardware raid controller.
Raid is pretty easy to setup imho.

I ended buying the kit in post #4, that'll do fine for me.

Yeah, you're right, which i think is a bit dumb of HP tbh.
So....been trying to find out if my RS2WC040 from my NL36 will work in this one, but haven't found any resources to say yay or ney.
Anyone know?
If not, what about the 'P' series of fully 6Gbit controllers?
Any recommendations?
