The Startech PEXSAT34RH RAID controller card is a device designed to expand and optimize a computer’s internal storage capabilities via a PCI Express 3.0 interface. This card adds 4 internal SATA III ports with transfer speeds up to 6 Gbps, ideal for connecting high-performance hard drives and SSDs, significantly enhancing data handling efficiency. Thanks to HyperDuo technology, this controller automatically manages a combined volume of up to three SSDs and one hard drive, maximizing performance by moving frequently used files in the background to faster SSDs, reaching up to 80% of typical SSD speed, provided the computer uses compatible BIOS. Additionally, the card supports Port Multiplier, allowing connection of up to seven SATA drives in total through a single cable, facilitating large-scale expansion without hassle. For security and reliability, this controller offers native hardware RAID support at levels 0, 1, and 10, providing effective options to improve performance, data redundancy, or both. Its hardware design includes a Marvell 88SE9230 chipset, known for stability and compatibility with Windows (up to Windows 10 Education and Enterprise), Mac OS X (from Yosemite to High Sierra), and Linux, confirming its versatility for professional and home environments. The device measures 120 mm wide, 70 mm deep, and 20 mm high, enabling installation in most PC cases with PCIe x2 slots. Verified performance shows sequential read speeds up to 490 MB/s with a single SSD and over 715 MB/s combining hard drives and SSDs in HyperDuo mode, demonstrating its ability to optimize intensive data flows and multitasking loads. Powered by a standard 240 V supply, this controller comes with an instruction manual for easy setup and operation. In summary, the Startech PEXSAT34RH is an efficient and robust solution for users and professionals needing to expand systems with multiple high-speed SATA III drives, combining advanced storage technologies with compatibility and flexibility in RAID volume management and performance optimization.
