The Startech.com PEXSAT34RH 4-Port PCI Express 2.0 SATA Controller Card adds 4x AHCI SATA III ports to a computer through a PCIe slot (x2), delivering multiple internal 6Gbps connections for high-performance hard drives and Solid State Drives (SSDs). Featuring HyperDuo technology, the SATA card offers SSD auto-tiering which lets you balance the performance advantages of SSD storage with the cost-effectiveness and large capacity of standard hard drives. By combining SSD and HDD drives into a single volume (up to 3 SSD + 1 HDD), HyperDuo discreetly works in the background to identify and move frequently accessed files to the faster SSD drive(s) for improved data throughput - up to 80% of SSD performance! (Note: The HyperDuo automatic storage tiering feature is compatible with computers that use a BIOS.) The PCIe SATA controller card supports Port Multiplier (PM), enabling multiple SATA drives to be connected to one port over a single cable, for a total of 7 drives (up to 4x drives through PM on one port, and a single drive to each of the remaining 3x ports). Plus, the SATA controller card offers an effective hardware RAID solution, with native RAID (0, 1, 1+0) support. Fits into any standard or low profile chassis with the included brackets. This PCIe SATA 6Gbps card is backed by a 2-year StarTech.com warranty and free lifetime technical support. * Bus type: PCI express x2 * Card type: Standard profile (LP bracket included) * Max drive capacity: currently tested up to 4TB per drive * OS compatibility: Windows 10, 8 / 8.1, 7, Vista, XP * Port multiplier: Yes * Ports: SATA III 6Gbps (7 pin, data) plug, x4 * Supported RAID modes: JBOD, RAID 0, RAID 1, and RAID 10 * System and cable requirements: available PCI express x2 slot (backward compatible with x4, x8, and x16 slots) * Product dimensions: 120 x 70 x 20mm * Manufacturer's part no.: PEXSAT34RH https://elecena.pl/product/27179869/startech-com-pexsat34rh-4-port-pcie-2-0-sata-iii-6gbps-raid-x2-controller 2024-11-08 https://elecena.pl/product/27179869/startech-com-pexsat34rh-4-port-pcie-2-0-sata-iii-6gbps-raid-x2-controller 2025-03-31 https://elecena.pl/product/27179869/startech-com-pexsat34rh-4-port-pcie-2-0-sata-iii-6gbps-raid-x2-controller 2025-05-16 https://elecena.pl/product/27179869/startech-com-pexsat34rh-4-port-pcie-2-0-sata-iii-6gbps-raid-x2-controller 2025-06-22 https://elecena.pl/product/27179869/startech-com-pexsat34rh-4-port-pcie-2-0-sata-iii-6gbps-raid-x2-controller 2025-08-01 https://elecena.pl/product/27179869/startech-com-pexsat34rh-4-port-pcie-2-0-sata-iii-6gbps-raid-x2-controller 2025-08-21 https://elecena.pl/product/27179869/startech-com-pexsat34rh-4-port-pcie-2-0-sata-iii-6gbps-raid-x2-controller 2025-10-02 https://elecena.pl/product/27179869/startech-com-pexsat34rh-4-port-pcie-2-0-sata-iii-6gbps-raid-x2-controller 2026-03-09 https://elecena.pl/product/27179869/startech-com-pexsat34rh-4-port-pcie-2-0-sata-iii-6gbps-raid-x2-controller 2026-04-02
