dual-port, high-performance SAS Drive and a high-capacity, Low-cost SATA Drive. So SAS drives and SATA drives can exist in one storage system at the same time. However, it should be noted that the SATA system is not compatible with SAS, so SAS drives cannot be connected to the SATA backplane. Because of the compatibility of SAS system, enabling users to use different interface of hard disk to meet the requ

Partition is the "section" of the hard disk ". Windows partitions have their own drive letters (C:, D:, and so on), which look like
bytes. Theoretically, this is not necessary, but it seems that there is no other value.Therefore, the maximum disk capacity is:255*1023*63*512/1048576 = 8024 GB (1 m = 1048576 bytes) or hard disk vendor commonly used units:255*1023*63*512/1000000 = 8414 GB (1 m = 1000000 bytes)In the CHS addressing mode, the value ranges from 0 to heads-1, 0 to cylinders-1, and
