Readynas NV+ SLOW TRANSFER SPEED
ReadyNAS NV+ RAIDiator 4.1.15 4x 1TB WD Green Raid 5 PC is gigbit, but my transfer speed maxes out at 12MB/sec. I've tried connecting directly to the NAS, and no change in speed. Jumbo frames...

I didn't realize that it doesn't actually use raid 5. I do need the redundancy to protect my data,
It has the same redundancy as RAID-5. The only difference is the organization of the parity blocks. RAID-5 distributes the parity blocks over all the disks, RAID-4 puts them all on a dedicated parity disk. Distributing the blocks evens out the I/O across the disks. Your NV+ has hardware acceleration for RAID, and I think that is why it uses RAID-4.
Newer NAS (NV+ v2, ultra, pro, all OS 6 NAS) use RAID-5.

is there a difference between the raid 5 and xraid?
XRAID is built on top of standard RAID. In your NAS it will convert from single disk->raid 1->raid 4 as you add drives. If you upgrade all four drives, it will also expand the volume automatically. As you likely know, the NV+ can't handle drives larger than 2 TB.
On newer NAS, it can also handle drives of different sizes, and (if you want it) dual redundancy.
Found this in my partition logs.

This is normal, so don't worry about it. I don't know why Netgear continues to run fdisk.
Still no luck. Backed up all of my data, did a complete reset, formatted to raid 5, still getting about 10MB/s write speeds. I'm thinking when I'm in the market for a new nas I might just avoid netgear. I used to have a WD Sharespace and it was faster than this, even though it was quite a bit older.
Your NV+ v1's hardware design goes back to 2006 - I don't think WD was building NAS back then. It's been end-of-life for over 5 years. A new ReadyNAS can delivers 50-100+ MB/sec on a gigabit network (depending on which model you purchase).
That said, 10 MB/sec is slower than it should be. Did you look at the ethernet stats for packet loss?
