Compliance: 1. Compliant with Serial ATA Port Multiplier Specifications. 2. Compliant with Serial ATA Port Selector Specifications. 3. Compliant with ATA PHY Series Electrical Specifications Revision 1.0 4. Compliant with Annex Specifications ATA Series High Speed Serialization. Specifications: Product: SATA3.0 1 to 5 Expansion Card Model: ADP6ST0-J05 Product Master: JMICRON JMB575 Product Package: Kraft Box Product Interface: SATA 7PIN System: For WINXP, WIN7, WIN8, WIN10 Size: Approx. 10.2*5.5*0.7 cm/4.02*2.17*0.28 in Package List: 1 * SATA3.0 1 to 5 Expansion Card 1 * USB-DC Power Cable 1 * Connection Cable 1 * Screw Bag Note: 1. This expansion card needs Motherboard or expansion card to support point(SATA Interface Multiplier) Funtion to identify 5 hard disks, common Motherboard SATA do not support such function. If not, only one hard disk can be identified. 2. Do plug in SATA or DC2.5 power cable to charge expansion card. 3. Cable Connection: Plug SATA input cable to Motherboard or expansion card to charge SATA. Support 6-Port: SATA3.0 1 to 5 expansion card supports 6-port 6.0Gbps SATA III interface. This expansion card requires the motherboard or expansion card support point (SATA Interface Multiplier) to recognize 5 hard drives. Normal motherboard SATA does not support this function. If not, only one hard disk can be recognized. High Performance: SATA III PHY output swing control and automatic impedance calibration. Plug in the SATA or DC2.5 power cord to charge the expansion card. Plug the SATA input cable into the motherboard or expansion card to charge the SATA. Asynchronous Signal Recovery: SATA3.0 card supports spread spectrum clock, asynchronous signal recovery, partial/sleep power saving mode, BIST and Loopback mode, interleaved rotation (optional), supports hot swap, asynchronous notification, ATAP driver, SWIT. About Specification: The SATA3.0 expansion card complies with the Serial ATA Port Multiplier specification, the serial ATA port selector specification, the ATA PHY series electrical specification revision 1.0, and the accessory specification ATA series high-speed serialization. Perfect Replacement: The SATA1 to 5 expansion card is a great replacement for the old or broken card.This product is a good choice for you. It can support part/dormancy power saving mode.
