I managed to scoop up two 150 GB 2.5" 10k RPM WD Raptors (enterprise, not consumer grade) for a measly $15 a piece since the were refurbished, which was perfect since I wanted something extremely cheap but fast and didn't care if they died randomly because it's just temp storage space. (I was considering cheap SSDs but figured that was just a money pit since they would probably die after a year or so due to all the reads and writes)
I will be striping these two together (may get a 3rd if it's worth it) and will be using it for a download directory for SABnzbd/NZBget, and maybe some other things, but largely downloads for NZBs. Since it will be doing a lot of unpacking/joining/copying.
My question is, is there a performance penalty associated with the tasks that ZFS does behind the scenes (CoW and other things), compared to just a simple RAID 0 array setup via mdadm (I'm using Linux until FreeNAS 10 is complete) with something like ext2 (no need for journaling) or XFS?
Also would it be beneficial to keep both the complete and incomplete folders on there or just the incomplete and put the complete in my multimedia pool which is 3 striped mirrors (6x 4 TB connected to my HBA) since it will be copying stuff from complete to my pool anyway?
....or was this a dumb idea to begin with and I should keep both directories within the pool? I had originally had the download directory on a single 2.5" laptop HDD and was getting abysmal transfer speeds so I got rid of it and put everything back in the pool. Since these are twice as fast, and there's two of them, that shouldn't be a problem this time.
