Drives in the machine:
1 x 60 GB Seagate (soon will have a second 60 GB Seagate to make the rpool a mirror)
5 x 1 TB Seagate Barracuda (storage pool, raidz1)
Raidz is basically 4 storage drive and 1 parity. I can lose a single drive out of the 5 installed and all of my data will still be safe. I will soon hopefully be getting some more money so I can add a sixth drive as the hot spare.
Copying data to it, I was unable to max out writing to it. My laptop internal hard drive does a maximum of 25 MB/sec, my external firewire drive maxes out at 30 MB/sec. Reading the data and then encrypting it over SSH to send with rsync sent my outgoing speed over my GigBit lan to 55 MB/sec, that caused reads from my internal drive and external drive to be maxed out, and my CPU to be maxed out encrypting the data to be sent over SSH. The server hardly hiccuped. I was watching zpool iostat, and every so often it would do writes out to the raidz1 at almost 200 MB/sec. Split between the 5 drives that equals to 40 MB/sec so I did not even max out the individual drives in terms of write speeds. Not sure what my kinda of cheap motherboard max transfer speed for SATA is when writing to all the devices on the SATA bus at the same time .
