Hi,
I already run UNRAID. I have around 5TB of Media storage, and 1GB of general documents (docs/pdf etc) . UNRAID is slow. I would like advice on selecting a NAS for my network that will provide me with the fastest speeds for managing my files. I will backup this NAS to my UNRAID server, so no need for redundancy, just speed. In terms of storage capacity, it would be nice to go to 5TB, but strictly speaking, this could be as little as 2TB.
I run Windows 7 pc's and Android tablets.
Thanks for the help.

Which part of your unraid is slow?
I can read from my unRaid box at over 70MB/sec (megabytes, so almost 7200rpm disk speed).
I can write to my unRaid box at around 60MB/sec (I have a cache drive)
This is more than enough to stream 4 HD movies at the same time (from the same disk!)
Given your requirements to no have any fault tolerance, it seems like adding a cache drive will fit the bill. If you have some extra cash then lash out and put in a big SSD for your cache drive!
Sure its not your network link at 100Mbit ?
Are you running gigabit?
It is very easy for a NAS to saturate 100Mbit switch (even a cheap one these days).

unRAID is pretty slow for writes since it has to deal with the parity (write to two disks) and limited to the speed of a single disk for reads since it's not striped.
An alternative for the OP would be to switch to FreeNAS or NAS4Free and used ZFS if the existing hardware is sufficient.

Forgot about the cache drive, but I have used unRAID quite a bit. Keep in mind that your data is not protected when it is on your cache drive but hasn't been written to the array yet.
I'm actually in the process of moving on to FreeNAS. I'm personally doing it for ZFS support, including double parity, checksumming, snapshots, etc. I just feel like my data will be more secure (not worried about media, but rather documents, family photos, and backups). Still deciding what to do with media, but thinking of moving it directly back into the HTPC since I only really have one xbmc client.
unRAID was plenty fast for just serving media, and even the level of data protection was fine for that. Not sure why the OP wants more speed.
