20 Port PCIe X1 SATA Adapter Card: PCI-Express X1 extends 20 x SATA III 6Gbps ports, so PC can access 20 x SATA drivers at the same time. You can setup a storage pool with 20 x SATA disks, or configure Software RAID in windows/Mac OS/Linux. (Noted: Can not support Hardware RAID)
Based on 4 x JMB575+1 x ASM1064 chip, Upstream PCI-Express 3.0 X1 Speed: 20 x SATA III 6Gbps ports share PCI-Express 3.0 X1 bandwidth (8Gbps), so all 20 x SATA III drivers can not reach 6Gbps at the same time.
Advantages and Disadvantages: This SATA adapter can connect with 20 x SATA disks, but only PCI-Express 3.0 X1 Speed at max. It is an economical and practical mass storage solution.
20 x LED Indicators: Red color is working status, Red flashing is data reading/writing.
Widely Compatibility: No need extra driver. Plug and play in Windows/Mac OS/Linux/NAS/UBUNTU/ESXI. (Noted: Can not support OS Booting)
