of all hard disk space. RAID 0+1: The combination of RAID0 and RAID1, which is a mirror relationship of two identically configured RAID0, improves both the reading speed of the array and the security of the array data, and, of course, the cost is also expensive. RAID3: is to divide the data into multiple "blocks", according to a certain fault-tolerant algorithm, stored in the n+1 hard disk, the actual data

First, we recommend you read the article: from N to N+1:multiclass Transfer Incremental Learning Core thought is transfer Incremental learning In the traditional machine learning hypothesis the training data and the predictive data obey the same data distribution. In many cases, however, the assumption of this distribution is not satisfied. Situations that do not satisfy the same distribution assumptions often occur when training data expires, and it
