If you put a line switch on 1-2 of the drives. You could manually stage them. Just make sure you have a good UPS unit. On startup the OS will proably report a bad drives (2) then you have problems with raid 5. It will proably start up with 3, then have the spare drive switched. The when a problem accours turn it on. Not running all the time in stand by you will have a good drive when that accours. We all know the Snap can rebuild an array with 3 drives, so if one starts up late, it will work. But will have the long resync or file check.

I think the in rush only last till the drives start spinning from a dead stop. Then drops off pretty quick.

If you have a patch or extender cable. Setup a fluke to measure the inrush, then you will have accurate data. Another note. My 2000 (fried) had a problem with loose power connectors early on. It tripped the fuse. After cleaning the connectors and tightening the sockets everything worked till the fan failed.

Just my 2 cents.

Not having one to play with, your on your own.
