Features:100% brand new and high quality100% brand new and high qualityThis adapter card supports desktop computer win8.1 64-bit professional version or higher system. Establish four soft RAID storage modesRAID1 (mirroring/SAFE mode): In this mode, the two disks are mirror images of each other, and the data are the same. If a disk is damaged, you only need to remove the failed disk and replace it with a disk equal to or larger than the capacity to automatically restore data without losing data.AHCI (PM mode):In this mode, the storage data of each individual disk does not interfere with each other, and each disk is an independent body inserting several disks to display several disksSPAN (BIG mode): In this mode, the capacity is the disk with the largest sum of all disk capacities, and the data will be stored on different disks.RAIDO (FSAT mode):In this mode, the data will be stored on multiple disks to form a whole, but the capacity is based on the capacity of the smallest disk multiplied by the number of inserted disks. The theoretical transmission speed is twice that of a single disk.Supports Serial-ATA (SATA) Gen III 6Gb/s hard drives, and is backward compatible with SATA I/II ;Made of high thermal conductivity material, the heat dissipation effect is better and more stable, the chip strengthens the heat dissipation, and the high temperature resistance is more stable.Package Includes:1 x PCIE Expansion Card1 x Short BaffleSpecifications:Product name: PCI-E 1X to 10 port SATA3.0 Expansion CardMaterial: MetalColor: BlackSize:approx12x10.4mm/4.72x4.9inInterface: PCI-E X1Expansion Interface: 10 x SATA3.0Supported system: Windows 7 32/64-bit/XP/Vista/WIN7/WIN8/WIN10Support hard disk: SATA interface Hard DiskInstallation method: in-line PCI-E card slotnote:Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
