Good to know, thanks.

I decided to stop the parity sync, and find out any drive problems before going further. I copied the drive performance script to the system USB drive, and executed it from the root account over SSH. It returned this error: "Error: There are invalid drives in the array" Is this because of the unfinished parity sync?

If I stop the parity, will it pick up where it left off when I start it again? Or will it start from scratch?

Hrmmmm... thanks for the info. Extra disappointing to see these speeds on my end, then. Hopefully a solution will be found soon (and hopefully one that doesn't require me returning the drives).

Diagnostics as attached. Thanks very much for your help. tower-diagnostics-20160706-1400.zip

It's 2x disks, but that's upsetting news. Could it perhaps be that the disks were damaged in transit? Are there any tests I can run?

'ullo! It's been a crazy few days! I was just about to buy a Synology DS916+ when a friend told me about the HP MicroServers and unRAID (I'd not heard of unRAID), and after a few days research and decision making, I decided that unRAID on a MicroServer was better in almost every way (the only exception being power consumption) than the Synology NAS, and found a good deal on a new gen8 MicroServer w/ 16GB RAM, and pulled the trigger. I've now set it up (firmware updates, enabling AHCI), and am running unRAID with 2x 4TB Seagate NAS drives in bays 1 & 2, and the parity is now syncing. Being so new to this, I of course now have some questions (most of which have been answered by the handy search bar). The one on my mind right now is about speed: the parity is building at ~33MB/sec, which seems slow (1 day, 53 minutes remaining after 9 hours so far). Is 33MB/sec perfectly normal for building the parity drive, or is there some setting I can change to speed it up? Further, is 33MB/s what I can expect for writing speeds until I save up for a cache drive (I was thinking it'd be around 60MB/s)? Many thanks.
