Ive never heard of unRAID before until now, it does sound like an interesting route in terms of setting up your RAID. Do keep me posted with your build, would be interesting to know how it plans out! At the moment i have a N54L with a P410 using X4 500GB disks in RAID5 & a 120GB SSD boot disk. I used to use it with xpenology and streamed movies around the house but after focusing more on my day job and dealing with servers i got Windows Server 2008 R2 Std on it and currently setting to run it as a data/Plex server. :D
Cheers for the response - Took a look around on the web and it looks like 16TB (4*4TB) was the biggest at the time of manufacturing so that's all they can officially say (y)
It's working fine, but I have 4x 6TB REDs in two mirrors, so its two 5.9TB volumes.
Don't worry - I do understand all the RAID options (0,1, 10, 5, 6, synology's SHR, etc.) pretty well. :-) With unRAID it uses one or more parity disks for resilience. I currently have one 4Tb parity disk and one 4Tb data disk. I didn't want to get 3x4tb disks initially, as this is my first NAS and I wanted to see how much use I would actually make of it. If I do make a lot of use of it then I will start adding extra data disks. The downside of the parity approach is that real time calculation of the parity means that data transfer rates fall from about 112Mb sec (I assume that this is limited by the 1 Gbit network) to about 40 Mb sec if transferring more than 1 or 2 Gb. unRAID allows you to use a caching disk to resolve this issue. I have already installed a 512Gb disk in the top slot on the microserver but I will only enable this once I have copied over the bulk of the data to unRAID. (As I understand it once I enable the cache disk the most data that I can write in a day to unRAID will be the size of the caching disk - as by default it only flushes once per day at 3:40am. I assume that I can change this to flush more regularly but I cannot see that I will be writing more than 512Gb per day once the NAS is fully up and running with all my data on it.)
