Need a NAS RAID recommendation

[AMD T-type]

I am currently in possession of four 2TB enterprise class hard drives and need a nas to put them in.

It needs to have at least 4 bays (obviously) and be active directory compatible.
Also needs to have built in RAID with the option to run RAID5.
Rackmount would be a plus but not required.

This was what I was originally looking at, however I've come to find out that the diskless "Pioneer" version does not support Active Directory.

Any help would be appreciated.

Apparently they do sell the Business Edition diskless

What did you decide on? Looking for the same exact thing, but without rackmount.

Or you can use this Five bay hardware raid with ITX board run under FreeNAS

It will transfer about 80MB/sec


If you want you can easily DIY with FreeNAS and hardware raid

i have 2x ReadyNAS NV+ running RAID 5. They've been bomber. I swapped out the installed 80mm fan for a quieter one.
