SABRENT M.2 SSD NVMe 4ドライブ PCIe 3.0 x4アダプターカード

This article covers SABRENT M.2 SSD NVMe 4ドライブ PCIe 3.0 x4アダプターカード.

Overview

The SABRENT M.2 SSD NVMe 4-Drive PCIe 3.0 x4 Adapter Card (model PC-P3X4) lets you install up to four M.2 NVMe SSDs on a single PCIe 3.0 x4 card. It's a practical solution for users who have run out of M.2 slots on their motherboard or need a large, fast storage pool without replacing their existing drives. Each of the four M.2 slots operates over an independent PCIe 3.0 x4 lane, so all drives can run at full speed simultaneously. The card itself uses a PCIe 3.0 x4 interface, which provides enough bandwidth for four drives in most real-world workloads.

Connectivity & Compatibility

Interface: PCIe 3.0 x4 (physically fits in x8 or x16 slots) Supported SSD form factor: M.2 2280 (80mm length) NVMe only OS support: Windows, Linux, and other OS with standard NVMe drivers Important: Your motherboard must support PCIe slot bifurcation (4x4x4x4 mode) to recognize all four SSDs. Without bifurcation, only one drive may be detected. Check your motherboard manual for "PCIe Slot Bifurcation" settings.

Product Info

Released around 2023, the card is priced at approximately ¥33,000 (as of June 2026). Warranty details are available on the manufacturer's website. The package includes only the card itself; you'll need to supply your own M.2 SSDs and mounting screws. This is a mid-to-high-end storage expansion card. Its standout feature is the ability to add four NVMe SSDs via a single PCIe slot, making it ideal for creative professionals, server builders, and anyone needing high-capacity, fast storage without sacrificing multiple M.2 slots.

Best Use Cases

Video editors and 3D renderers: Store large project files, caches, and scratch disks on fast NVMe SSDs. With four drives in RAID 0, sequential read/write speeds can be significantly boosted. Note that RAID requires motherboard RAID support or software RAID. Home server or NAS builders: If your motherboard has a free PCIe slot, this card adds four SSDs for a storage pool. Bifurcation support is mandatory, so verify compatibility before buying. * Users with limited M.2 slots: ITX or some microATX boards often have only one or two M.2 slots. This card provides a way to add NVMe storage via PCIe without replacing the motherboard. ## Alternatives
Direct competitors include the ASUS Hyper M.2 x16 Gen 4 Card and the HighPoint SSD7101A-1. The ASUS card supports PCIe 4.0 for higher bandwidth but costs more. The HighPoint card includes built-in RAID hardware but is even pricier. Sabrent's offering is a solid value choice for PCIe 3.0 systems, providing four NVMe slots at a competitive price.

Things to Consider

The most critical requirement is motherboard bifurcation support. Without it, the card may only recognize one SSD or fail to boot. Always check your motherboard manual for "PCIe Slot Bifurcation" settings before purchasing. Also, this card is limited to PCIe 3.0 x4 speeds (around 4 GB/s per slot). If you install PCIe 4.0 SSDs, they will run at PCIe 3.0 speeds. For full Gen4 performance, consider a PCIe 4.0 adapter. The card uses a full-height bracket and does not include a low-profile bracket, so ensure your case has enough clearance.
