This article covers 2ポートPCIEインターフェースアダプターカード.
Overview
This 2-port PCIe interface adapter card adds two SATA ports to a desktop PC, allowing connection of internal hard drives or SSDs. Simply plug it into a spare PCIe slot (x1 or larger) to expand storage capacity. With a maximum data transfer rate of 5Gbps, it supports SATA III speeds and is a cost-effective solution for users who need extra SATA connectivity on an older motherboard or a budget build. Positioned as an entry-level accessory, it offers a simple way to increase storage without replacing the entire system.
Compatibility Guide
The card fits into any standard PCIe slot (x1, x4, x8, x16) and is compatible with ATX, MicroATX, and Mini-ITX motherboards. No additional power cable is required as power is supplied through the PCIe slot. It works with most SATA hard drives and SSDs, but check your system's total power supply capacity when using multiple devices. Some motherboards may require BIOS settings adjustment for booting from drives connected via this card.
Product Info
This adapter card is sold on by a generic manufacturer, with a price around 1,600 JPY (~$11 USD). Warranty terms vary; refer to the seller's page. It targets entry-level users who need a cheap and quick way to add SATA ports. Performance depends on the underlying chipset, which is not specified here, so it's best suited for standard file storage and backup rather than high-speed RAID or intensive workloads.
Best Use Cases
Users with older motherboards lacking enough SATA ports: easily connect additional optical drives or HDDs. Home server or file storage enthusiasts: add multiple SATA drives to a compact system. * Budget-conscious PC builders: a minimal-cost upgrade that works out of the box.
Things to Consider
The chipset used in this card is unknown, which means actual performance may vary. It may not support all SATA features (like hot swapping or TRIM) reliably. Booting from drives attached via this card may require specific BIOS settings, and it might not be recognized by all operating systems without additional drivers. If you need high throughput or RAID functionality, a branded controller from Marvell, ASMedia, or similar would be a better investment.
