Why is UNRAID cool for home?

I’ve played with many storage technologies at home, ZFS being one of my favs when it comes to performance. But i’ve been looking for something that suits a typical home environment where power usage and capacity is usually more important than performance. Thats where UNRAID has come in…

UNRAID give me these advantages;

Different sized disks in a single pool (only requires largest disk as parity)
Files are distributed over all the disks - so even if you lost more than a single drive you still still have some of your data. Note : with parity drive you can handle a single drive failing without loosing anything, sorta like RAID4 - non distributed parity.
Power usage, since the files are stored on specific disks not all the disks need to power on to give you your file.
Runs on a USB stick - no large operating system required.
Crashplan module can be installed to provide backup options.

I’ve had a play with WHS but eventually got annoyed with its lack of performance. Yes i know its not built for performance and typically is used just as a backup / simple store with duplication as redundancy, just i couldn’t stand the speed of the thing. If you were ever unlucky enough (even post power pack 1) to do a copy during the “data moving” the performance was even worse. On a positive note nothing beats it if you have a heap of non-similar sized disks that you want to put together (with redundancy) as a single shared storage pool.
