Two hard drives to build a RAID0 disk array simple tutorial (picture and text) _ Server Other

Traditional hard drives are very slow to improve performance because of the limitations of their working principles. But the solid state hard disk price is expensive, in a short time is difficult to accept by the ordinary user. Therefore, the use of two or more pieces of hard disk to build a RAID disk array has become a more cost-effective hard disk performance i
