hardware is completed...
raid 6 vs raid 50 for 12 4tb show this, mb/s:
raid 6/raid 50
seq q32t1 1697-95/1677-208
4k q32t1 34-5.4/50-5.4
as my storage is slow write speed is not concern.
I think that raid 6 is better solution because ANY of two hdd can fail and raid will be ok...raid 50 have much better write but if two disk go bad in same strip sub array entire raid will go down.
strip size, 256kb or 512kb?
enable or disable write cache on controler? wont have baterry but we have ups and gen set.
