Sedna - PCIe 4X - Quad 2.5 Inch SATA SSD RAID Controller Card RAID 0110 Marvell HyperDuo Technology with Built in Power Circuit, no Need SATA Power

** Sedna PCIe 4X Quad 2.5 Inch SATA SSD RAID Controller Card** The Sedna PCIe 4X Quad 2.5 Inch SATA SSD RAID Controller Card offers a unique solution for users looking to optimize older or budget-level SSDs. This card is capable of supporting RAID 0, 1, and 10 configurations through its Marvell 88SE9230 chipset. However, it lacks comprehensive instructions or guidance for setup, which may pose a challenge for users unfamiliar with RAID configurations. Despite this, users have found the configuration process manageable after installing the Marvell Storage Utility and ensuring that their operating system recognizes all connected drives. Users have reported mixed performance results; while the speeds achieved with this controller are decent for a budget option—particularly when using a mix of SSDs—the card does not deliver the high speeds associated with modern SSDs. With combined read/write speeds around 680 MBps based on a configuration of two Crucial and two Macron SSDs, it provides a notable improvement over non-RAID setups and USB enclosures. Nonetheless, the card is limited to PCI-E v2, which prevents it from fully utilizing the potential of SATA III speeds. A noteworthy concern is the card’s unusual physical design. Its layout might complicate installation in tight spaces, as the mounted drives extend further than expected. While users have had success with software RAID on MacOS Catalina, there is no native hardware RAID support for Mac, which limits its versatility across different platforms. In summary, the Sedna RAID Controller Card is an affordable entry point into RAID configurations for users with older drives. It effectively enhances the performance of slower SSDs but comes with several limitations, including speed Constraints and a lack of clear setup guidance. **
