This article covers 4 in 1 PCIe 5.0 X16 から 4 ポート分岐 PCIE 分割アダプターカード E1.S E3.S EDSFF ハードディスク分割拡張拡張用.

Overview

This adapter card converts a single PCIe 5.0 x16 slot into four independent ports for U.2, E1.S, and E3.S (EDSFF) drives. It is designed for servers and high-end workstations that need to expand storage capacity without replacing the motherboard. The card features gold-plated connectors (10U thickness) to ensure signal integrity and long-term durability. With PCIe 5.0 bandwidth (4×128Gbps), it allows multiple high-speed NVMe SSDs to operate at full potential. By using this card, you can connect up to four NVMe SSDs from a single PCIe slot, significantly boosting storage performance and capacity. It is especially useful when your motherboard lacks additional M.2 slots or when you want to leverage enterprise-grade drive form factors like E1.S or E3.S.

Key Features

PCIe 5.0 x16 support (4×128Gbps) : Each port can utilize full PCIe 5.0 bandwidth, enabling fast simultaneous data transfers for demanding workloads like real-time analytics or large file processing. 4-port independent expansion : Attach up to four U.2/E1.S/E3.S drives per card, allowing RAID configurations or tiered storage setups without consuming multiple PCIe slots. Gold-plated connectors (10U) : Reduces contact resistance and improves reliability over time, ideal for 24/7 server environments. Included baseplate for E1.S/E3.S : Ensures precise alignment and secure mounting of enterprise drives, preventing vibration-related connection issues. * Wide drive compatibility : Supports U.2 (SFF-8639) and EDSFF (E1.S, E3.S) SSDs, making it easy to reuse existing enterprise storage.

Compatibility Guide

The card fits into any PCIe x16 slot (gen 5.0, 4.0, or 3.0) and works with U.2 and EDSFF drives. It does not directly support M.2 SSDs, but adapters exist. The card likely uses a full-height PCIe bracket; low-profile compatibility is unconfirmed. Power is drawn from the PCIe slot (up to 75W), so drives with high power draw may require additional SATA power connectors. Check your motherboard manual for PCIe Bifurcation support – it must be enabled in BIOS to recognize all four ports.

Product Info

Available on since around 2025, priced approximately ¥8,000–¥12,000 (price varies). Warranty is determined by the seller (QiQuan1), typically one year. Supports PCIe 5.0 x16 with up to 128Gbps per port. Gold-plated connectors (10U) included. No drives are included.

Best Use Cases

Data center administrators : Add extra E1.S/E3.S drives to existing servers without replacing the motherboard, maximizing limited PCIe slots. Content creators needing fast storage : Build a high-capacity NVMe RAID array for video editing or 3D rendering workstations, achieving sequential speeds beyond single-drive limits. * Home lab enthusiasts : Expand storage on older motherboards that still have PCIe slots, a cost-effective way to add multiple NVMe SSDs.

Things to Consider

This card does not come with drives – you must purchase U.2/E1.S/E3.S SSDs separately. Not all motherboards support PCIe Bifurcation; check your BIOS options before buying. If your drives consume more than 75W total, you may need supplementary power. The card is aimed at enterprise users; consumer systems may find it overkill unless they have specific storage expansion needs. Also, verify that your case has clearance for a full-height card and the drive mounting area.
