JMT PCI-E to 5-Port SATA 3.0 Expansion Card 6Gbps PCI-E X4 Controller Board Support for PC Computer Cascaded (Full Height Bracket)

JMT PCI-E to 5-Port SATA 3.0 Expansion Card 6Gbps PCI-E X4 Controller Board Support for PC Computer Cascaded Parameter: Size: 120*80mm Interface: Support PCI-E X4 (compatible with X8 X16) interface Output Interface: SATA3.0*5 System: Compatible with MAC OS/WINDOWS/LINUX Weight: 47g The system comes with soft RAID, supporting 4 storage modes. The expansion adapter board Compatible with desktop PCs with WIN8.1 64-bit Professional Edition or above,and four soft RAID storage modes are supported. RAID1 (Mirror (SAFE mode)) In this mode, two disks are mirrored and backup each other with the same data. If one disk is damaged, just remove the faulty disk and replace it with a disk of equal or greater capacity to automatically recover data without losing data. AHCI1 (PWM Mode) In this mode, each individual disk stores data without interfering with each other and each disk is independent. Each disk is an independent entity and the number of disks inserted will be displayed. SPAN (B16G mode) In this mode, the capacity of all disks is added up to the largest disk, and the data will be stored on different disks. The data will be stored on different disks, the disadvantage is that the data will be lost and not recovered if the disk is broken. RA1D0 (FSAT mode) In this mode, data will be stored on multiple disks to form a whole, but the capacity is multiplied by the capacity of the smallest disk. However, the capacity is based on the capacity of the smallest disk multiplied by the number of inserted disks, and the theoretical transfer speed is twice that of a single disk.
