This article covers PCI-E4X8X16X 拡張カード.

Overview

The Yunseity PCIe to 6-Port SATA 3.0 Expansion Card adds six SATA 3.0 ports via a PCIe 3.0 x4 interface. It supports Windows 8/10, Synology DSM, and Ubuntu, making it a versatile option for expanding storage on older PCs or NAS devices. With a price around ¥11,469, it offers a cost-effective way to connect multiple HDDs or SSDs without upgrading the entire system.

Connectivity & Compatibility

The card uses a PCIe 3.0 x4 lane, fitting into x4, x8, or x16 slots. It provides six SATA 3.0 (6 Gbps) ports for connecting storage drives. Compatibility is listed for Windows 8/10, Synology DSM, and Ubuntu. Note that the chipset is unspecified, so compatibility with specific motherboards or NAS models should be verified. The x4 lane bandwidth is shared among all six ports, meaning simultaneous full-speed access may be limited.

Product Info

Sold on online retailers for approximately ¥11,469. Warranty and accessories vary by seller. This card sits in the entry to mid-range market, offering six ports at a low cost compared to branded RAID controllers. However, build quality and driver support may be less robust, making it more suitable for home labs and hobbyist NAS builds than mission-critical servers.

Best Use Cases

  • Users needing extra SATA ports on an older PC: If your motherboard lacks enough SATA headers, this card adds six ports for connecting SSDs or HDDs. Ideal for bulk storage or media servers.
  • Synology NAS owners with a free PCIe slot: The card is listed as compatible with Synology DSM, allowing additional drive bays in compatible models. Check your NAS model's compatibility list before purchase.
  • Budget-conscious home server builders: For software RAID or simple JBOD setups, this card provides a cheap expansion path. Avoid if you need hardware RAID or enterprise-grade reliability.
