Want to ask, in addition to the solid state do system,
Three pieces of machinery is made raid 1 put two pieces of data, do another piece of data backup,
Or make it raid5, all three pieces of machinery and then score according to partition and data backup partition,
Two kinds of practice, the size can be used, it is 4 t, are not bad two blocks at the same time,
Raid5 may speed quick, but it is said that the large capacity raid5, bad after a piece of, have a chance to restore,
Bosses, a recruit!
CodePudding user response:
Yes, reconstruction of raid5 array is likely to fail, easily, the greater the failure probability, the greater the suggest add a piece of hard disk, do RAID10 4 hard drives,
