July 17, 201114 yr SO I have seen some talk about an app drive, my understanding is it is a seperate drive that holds all the apps that may be running. Here is my question I have the 24 bay norco, now there is more room to fit a drive or 2 could I add a 25th drive to use that as an app drive or does it need to be part of the array?

It is best if it is NOT part of the array.. That way it does not impact the start-up or shut down of the protected array.
July 17, 201114 yr so I could use a 25th drive to have the apps on? As Joe L stated, it is preferred to have all your apps on a drive that is outside the array. So the answer is yes. My question to you is how are you using all 24 drive bays in your Norco for unraid? The maximum number of drives for the pro version is 20 data + 1 parity + 1 cache = 22 drives. So you should have two extra drive bays available. I don't understand why you need a 25th drive, if you added a dedicated app drive it would be your 23rd drive.
July 18, 201114 yr Author ok so lets go the 23rd drive then. I am hoping in the near future unraid will support upto 24 drives. with the norco 4224 available it is possible for 24 drives. The main point I was trying to get was since there is still lots of room in that case I could easly mount an extra drive or 2, judt figuring out if I do put a dedicated app drive in there and unraid alows 24 drives in the future I wont have to open up the case. to get the 24 drives + 1 app.

You can use a tiny portion of the same physical drive used for cache and have absolutely no impact on the array starting or stopping. You just need to define the second partition, mount it, and then use it. (cache as partition 1, your "apps" have partition 2, and yes, if you wish, you can even define a third partition as swap space)

July 19, 201114 yr just wondering... if the apps partition is on the same physical drive as the cache partition... could this possibly slow down writes to the cache drive?
July 19, 201114 yr just wondering... if the apps partition is on the same physical drive as the cache partition... could this possibly slow down writes to the cache drive? Most computers only have one drive. Does not seem to bother them.
July 19, 201114 yr Depends on the app. If you are using something like Sabnzbd, downloading, running par2, unrar, and copying data to your cache drive too, writes to your cache will be seriously degraded.
